Cheap Surround Sound System with Amazing Quality?

I just setup a buddy with a cheap system and he LOVES it. The Energy 5 Micro is onsale at Crutchfield for $399 shipped and it's 4 surround speakers, a center, and a subwoofer. In terms of receivers you can save a bunch and buy a 5.

1 receiver instead of a 7. 1 receiver. Most people do not have 7 speakers to hookup anyway.

The newer Pioneer line of receivers (519, 819, 919, and 1019) all got outstanding reviews for their functionality and sound, and they range from $200-$500

1. Whats a sufficient yet affordable 7.1 Surround sound system ?

Amazingly the Sony STR-DH700 7.1 is a good sounding and affordable system that I would recomend.

I hate to say it but I have an Onkyo 805 and my friend bought the Sony and brought it over and it really does sound ... better in a way... It seems to get loud and crisp sounds.

But I do love my Onkyo it has good set ups.

2. Does the Turtle Beach Earforce P11 Headset Have Surround sound?

I think the work your looking for is stereo, or it can play a different sound in each ear.

Yes, they do that. It does sound like it is surround, though. I wonder of they will every make headphones that go around your head, truly surround :o

3.

What should I do for surround sound?

Well, I would suggest you increase your budget a bit & forget the idea of wireless speakers. At this point, all you need is a decent receiver & 5 speakers + a sub.

So, go that route. A home theater in a box is cheap. Wireless speakers have limited frequency range.

The newest Blu-ray discs have a full frequency range coding for the surround. So you will want speakers with the biggest frequency range you can get. The way home entertainment technology has turned, trying to get anything on a budget under $300 is just about impossible.

Last year in Oct & Nov, it took me nearly $2.5K to update my system with discrete surround, flat screen HD TV, & Blu-ray. Plus all new wiring. And my system, while still very nice, is still small in comparison to others.

Get a Yamaha RX-V663 receiver ($499) and Polk Audio speakers ($399) See link.

4. Will you help me find a surround-sound audio switching solution?

I have to assume that whatever you are using the multi-channel analog inputs for now has higher priority than your SACD player ....

otherwise I would suggest running whatever that is via optical and plug in the SACD. Assuming that is not an option (and I agree using splitters to combine two outputs is not a good idea) you are not going to find anything cheap. The first link is to a review of a multichannel analog switch that would do the job ...

but $450 is pretty steep. The second link is for an even fancier model for more $. At these prices I would suggest trading your DVD/SACD player for a new Oppo BDP-83 (last link) ...

it's no doubt superior to your present one and will add Blu-ray capability for $499.

5. Can a surround sound be achieved with a 4 channel stereo?

Yes, if you add two rear speakers you will get most of the surround sound effect.

Another good addition is a front center speaker for dialog. Most of the time if you are not a real audiophile, 5 speakers like that will sound just as good as a fancier setup.

6. What HDTV should I go for?

If you plan on getting a blue ray player, then you want to get the 1080p. Look for 60,000 to 1 ratio, you want to maximize your blue ray experience. You might want to check for HD MI ports and RCA ins and outs.

There very important for Surround sound and High def

7. Whats the best surround sound system I can buy?

I like Ryan L's answer.

You can get good components for the money you want to spend. Sony and Bose are low end and well suited for double wides and RV's. People buy them without even listening or reading the reviews.

Stereo shopping is fun. Bring a few cd's and spend a day and go to a few shops. You will enjoy the time and be a lot smarter about your choices.

Good luck!

  • Hampton-on-Sea of Cheap Online Shopping

    Hampton-on-Sea was a drowned and abandoned village in what is now the Hampton area of Herne Bay, Kent. It grew from a tiny fishing hamlet in 1864 at the hands of an oyster fishery company, was developed from 1879 by land agents, abandoned in 1916 and finally drowned due to coastal erosion by 1921. All that now remains is the stub of the original pier, the Hampton Inn, and the rocky arc of Hampton-on-Sea's ruined coastal defence visible at low tide.

    The site is notable for sharing its history with the eccentric Edmund Reid. Reid was previously the Metropolitan Police head of CID who handled the Jack the Ripper case. In retirement he chose to champion the plight of the beleaguered residents of the settlement.

We try to understand the psychology and ideas behind it.Section topic: The statistics on snow flurries in Washington DC area during January 29th 2014Introduction: This article will give an introduction on snowflurries and their statistics in Washington DC area during January 29th 2014. By analyzing all data collected by the National Weather Service (NWS), we can get a better understanding on how people react to snowfall events and what they do when they see it.solar street light turn on and off automatically, how does it work?Operation principle of solar street light's switch on and off function The output voltage (or charging voltage) of the solar panel determines the switching on/off operation, and the brightness of the sunshine determines the output voltage of the solar panel. Therefore the brightness of the sunshine determines the charging voltage of the solar charger controller. Charging voltage increases as the light intensity rises, and decreases as light intensity decreases. Solar street lights generally do not require a separate timing switch, because the controller can do a better job of switching the lights on and off automatically. The biggest advantage of solar streetlight is the elimination of buried wires, which can save the 2 major costs of digging and filling the ground, and purchasing cables. If the switch is set up uniformly, then these two costs are spent as usual (of course, the cable can be changed to a thinner signal line). So the solar led street lamp needs an auto switch function, otherwise, it will lose the meaning of solar energy. The good thing is that the development of the single-chip computer has been fully equipped to complete this task brilliantly. Solar street lights are generally composed of four major parts: solar panel, battery, LED lamp head, and solar charge controller. The solar charge controller places a very important role to take care of the charging and discharging, but also the "brain" of the solar system, which takes care of the switching on/off, working time, and light power management. Solar street light turn on and off automatically, how does it work? Back to the solar panel itself that the silicon chips integrated with the solar panel are photosensitive electronic components, and there is no need to add an extra light sensor. The output voltage (or charging voltage) of the solar panel determines the switching on/off operation, and the brightness of the sunshine determines the output voltage of the solar panel. Therefore the brightness of the sunshine determines the charging voltage of the solar charger controller. Charging voltage increases as the light intensity rises, and decreases as light intensity decreases. When the charging voltage determined with a certain value (e.g. below 5v to switch on and above 5v to switch off), the micro-controller in the controller will automatically turn on/off the electronic switch to turn on/off the solar street light. A lot of tests and experiences tell that solar charging voltage at 5v is the right moment to switch on/off the lights, it has been a standard value for solar controllers and photo-controller devices. At ANETHIC, we provide much flexible solutions for all these parameters, you can even determine them yourself to make your very personal decisions.

Importantly, challenge-response pairs differentiate our protein-based PUFs from other common unique objects and tags29,63. In reaction to optical challenges, defined by a unique set of excitation and emission bands of different fluorescent proteins, the edible PUF made of silk protein (i.e., fibroin) and fluorescent proteins generates distinct output responses, which are used to extract digitized keys (Fig. 1a). The source of entropy is randomly distributed fluorescent silk microparticles seamlessly embedded in a covert thin transparent silk film. First, we take advantage of four different fluorescent proteins (i.e., eCFP, eGFP, eYFP, and mKate2) that have specific excitation and emission peaks in the visible wavelength range (Supplementary Table 1). Specifically, we utilize fluorescent protein-expressed silk produced by transgenic silkworms as recombinant proteins via the piggyBac transposase method (Supplementary Methods and Supplementary Fig. 1a). Silk proteins are an excellent biopolymer to be genetically hybridized with fluorescent protein genes46,55,57,59. Second, to fabricate fluorescent silk microparticles (Supplementary Fig. 2), fluorescent silk fibroin is regenerated into an aqueous solution with a low-temperature process, is freeze-dried, and is gently ground into zeolite-shaped microparticles with sizes of 99.3 7.9 m (mean standard deviation) (Fig. 2a, b and Supplementary Fig. 3). Third, an admixture of the fluorescent silk microparticles is broadcast on a large flat surface and a white silk fibroin solution is poured on top. After an ambient drying process in the dark, this thin transparent silk film with a thickness of 150 m is punched into 7 7 mm2 squares, resulting in all protein-based edible PUF devices (Methods and Supplementary Figs. 2 and 4). eCFP, eGFP, eYFP, and mKate2 silk cocoons possess bluish, greenish, yellowish, and reddish colors under white light illumination (Supplementary Fig. 1b). However, after the regeneration of the fluorescent silk, each type of fluorescent silk microparticles are not distinguishable in the naked eye, while maintaining their fluorescent properties (Fig. 2 and Supplementary Fig. 5). This fabrication process is scalable for mass production without using any sophisticated equipment and is safe for oral consumption without any organic solvents or synthetic polymers (e.g., methanol, ethanol, isopropanol, or polyvinyl alcohol) (Methods and Supplementary Fig. 6a). Analyses of mass spectroscopy, energy-dispersive X-ray spectroscopy, and in vitro cytotoxicity (cell viability test) assays support the overall nontoxicity of the edible PUF devices (Supplementary Methods and Supplementary Figs. 7-9). In Fig. 3, the flow diagram illustrates how a cryptographic key is extracted from an output response when challenged by a set of excitation and emission bands, including the raw output measurement, the bitstream extraction, and the final digitized security key. We mainly use four representative challenge-response pairs (n = 4) based on the excitation and emission peak wavelengths of the individual fluorescent proteins in silk (Supplementary Table 1 and Supplementary Fig. 1c). An input challenge (C ) is selected as a combination of the excitation and emission bands at specific wavelengths such as = 415 nm and = 460 nm; = 470 and = 510 nm; = 470 and = 560 nm; = 530 and = 630 nm, corresponding to eCFP, eGFP, eYFP, and mKate2 in silk, respectively. Upon optical excitation, a raw fluorescent image is recorded by a charge-coupled device (CCD) camera equipped with a conventional zoom lens via a tunable color filter (Methods and Supplementary Fig. 10a). In other words, the corresponding fluorescent image acts as an output response (R ). A resultant digitized key (K ) is obtained by an extractor that converts the fluorescent image of silk microparticles to a binary bitmap (Fig. 4). First, to improve the quality of binarization, we normalize the raw fluorescent image (300 pixels 300 pixels) by the maximum intensity (Fig. 4a). The noise is removed by applying a threshold of 20%. Fluorescent areas smaller than a specific pixel size of 20 are also considered as noise. Then, the image is resized to be 150 pixels 150 pixels with a binning process. Second, to ensure a low bit error rate (high reproducibility), we find the spatial peak position of each fluorescent silk microparticle where the highest intensity peaks of the microparticles are located, subsequently reducing the image size to 50 pixels 50 pixels (Fig. 4b). Then, the peak positions are only assigned to 1 bits and other pixels are 0 bits. Third, to remove the bias of 0-bits, we apply an enhanced version of the von Neumann bias compression algorithm with two-pass tuple-output debiasing (Fig. 4c)64. Because the fluorescent peaks are relatively rare events in the entire image due to the density of the fluorescent microparticles, global bias is present such that 0-bits are generated consistently more often than 1-bits. Finally, after debiasing, we use first 64 bits as a digitized key in each response, because a typical minimum number of peaks in the fluorescent images is 32. Combining four challenge-response pairs (n = 4) together, the final digitized key size results in 256 bits (=4 64). We assess the quality of randomness of the edible PUF-generated binary sequences, using the NIST statistical test suite that was originally designed to evaluate random and pseudorandom number generators65. One of the minimal requirements of PUFs is randomness with high entropy, as PUFs rely on an entropy source to create an unclonable output response66,67. When PUF responses are used for cryptographic key generation, it is also critical to evaluate the randomness to ensure the unpredictability of the keys generated by PUFs. The NIST statistical test suite includes 15 different tests to quantify the randomness of bitstreams. Each test focuses on a specific aspect of randomness (Supplementary Table 2). Some of the tests rely on the minimum sequence length of 1 106 and the minimum number of substrings (blocks) of 55, requiring a total stream of 5.5 107 bits. On the other hand, the key size of the edible PUFs is significantly shorter than those of random number generators. To use seven statistical tests that require a reasonable stream length, we explore the randomness of binary sequences summed from 30 different PUFs (Fig. 5). Specifically, we collect a total of 7680 bits from 30 different PUFs (256 bits for each PUF) and divide the bitstream into 60 sequences to perform each statistical test 60 times on individual 128-bit long sequences (Supplementary Dataset 1). Each statistical test returns two results; a p-value of a chi-squared (2) test and a pass rate (i.e., proportion), as shown in Table 1. As summarized in Table 1, the binary sequence from the 30 different PUFs passes all of seven NIST randomness tests without any post-processing. The parameter values used in each test and the characteristics of the NIST randomness tests are summarized in Supplementary Table 2. In other words, the bitstream (7680 bits) extracted from the 30 PUFs is statistically random, supporting the idea that the output responses of all protein-based PUFs can be unpredictable and unclonable. This result also supports the idea that our simple broadcasting process of particulate fluorescent silk offers a random spatial distribution as a straightforward yet effective entropy source60,61. To evaluate the basic PUF performance, we examine the digitized keys of the edible PUFs. We first estimate the bit uniformity by checking the equal probability of observing 1-bit or 0-bit states: where K is the lth binary bit of the key and s is the key size. Basically, the bit uniformity is the Hamming Weight (i.e., number of 1 bits in a binary sequence) of the s-bit key. For 30 different PUFs, the distribution of bit uniformity converges to the ideal value of 0.5 (Fig. 6a). Then, to evaluate the device uniqueness of each PUF, we calculate an inter-device Hamming Distance (HD) by counting a number of different bits between two PUFs under the same challenge. The device uniqueness measures the degree of correlation between digitized keys measured from two different PUFs. Ideally, the digitized keys from any two selected PUF devices should be uncorrelated, indicating that the state of a PUF is unknown even when the states of other PUFs are known. The inter-device HD between any two PUF devices can be defined: where K and K are s-bit keys of the ith PUF device and the jth PUF device among q different PUFs, respectively. The 30 different PUF devices generate a total of C (=30 29/2 = 435) comparisons. In Fig. 6b, the histogram of the normalized inter-device HDs is well fitted into a Gaussian distribution with a center at 0.5032 with a standard deviation (SD) of 0.0458, which is close to its ideal value of 0.5, exhibiting the excellent device uniqueness of all of the edible PUFs. In addition, we investigate the degree of correlation among the digitized keys of four responses in each PUF by calculating an average HD (Fig. 6c). The 30 different PUFs result in a mean HD value of 0.499 with a SD of 0.0041, indicating that the individual digitized keys in each PUF are also unique. When the number of challenge-response pairs is extended to seven, seven resultant digitized keys are still uncorrelated with a mean HD value of 0.5089 with a SD of 0.0766 (Supplementary Figs. 11 and 12). In addition, we calculate an encoding capacity of the edible PUF-generated binary sequences. The encoding capacity simply means a number of codes that can be generated and is defined as cs where c is the bit-level (c = 2 for binary bits of 0 and 1) and s is the key size38,68. To accurately estimate the encoding capacity, it is important to use an appropriate key size. When an imaging scheme is used, one may think that the total number of pixels (variables) is the digitized key size. In this case, the actual encoding capacity can be less than this nominal encoding capacity, because each individual pixel (variable) cannot be completely independent. One way for estimating the number of independent pixels (variables) is to analyze the degrees of freedom; s = p(1 p)/2, where p is the mean probability and is the standard deviation31,34. In Fig. 6b, the resultant width of the inter-device HD distribution shows that significant subsets of the key are mutually independent, corresponding to the degree of freedom (or number of independent variables) of 120 (0.5032 (1 0.5032)/0.04582). As a result, the edible PUF has c = 2 and s = 120, resulting in a relatively large encoding capacity of 2120 (1.3292 1036). Importantly, the debiasing process is useful not to comprise the actual coding capacity. If a security key is biased with too many 0 s or 1 s, the actual coding capability is often diminished. A large encoding capacity could be utilized to provide information on manufacturer-determined data, including dose information (e.g., dosage strength, dose frequency, and expiration date), manufacturing details (e.g., location, date, batch, and lot number), and distribution path (e.g., country, distributor, wholesaler, and chain). If a higher encoding capacity is required for a specific application, the key size of our edible PUF can simply be scaled by further optimizing the density of fluorescent silk microparticles, which allows for a larger number of peaks in each image. The number of challenge-response pairs can also be increased by incorporating additional combinations of the excitation and emission bands (Supplementary Fig. 11). To examine the feasibility for reliable PUFs, we test the readout reproducibility and stability of the security keys from the identical PUF device. The reproducibility of a PUF represents the ability of generating the identical keys following the same repeated challenges. We calculate an intra-device HD, which is quantitatively described by a bit error rate (i.e., percentage of error bits out of response bits with an ideal value of 0) from 10 challenge-response cycles (nine pairwise comparisons) for each PUF device. For the ith PUF device, an average intra-device HD captures the readout reproducibility: where K and K are the original s-bit reference key and a s-bit key extracted from the same PUF device at a different time-point t and m is the number of repeated measurements. Figure 6b shows a relatively low mean value of 0.0632 with a SD of 0.0164 estimated from the intra-device HD histogram for the 30 different PUFs at the same 10 challenge cycles. We further examine the long-term reliability under the same challenges after 60 days in the laboratory environment (i.e., stored at 22 2 C and 40-50% relative humidity in the dark) (Supplementary Fig. 13). When the fluorescent intensity of the raw fluorescent images taken 60 days apart is compared, the correlation coefficients (r) of the four responses (R , R , R , and R ) range from 0.833 to 0.983. For the pixel positions of the first 32 peaks in the binarized images, the r values are even higher than 0.895 for all of the responses. These results support the potential reliability of the protein-based edible PUFs, although the reproducibility assessments do not reflect extremely harsh conditions, given the medical applications. We further estimate a false positive rate and a false negative rate from the inter-device and intra-device variabilities. When PUFs are used for authentication, the false positive rate is the probability that PUF A is authenticated as PUF B. The false negative rate is the probability that a correct PUF fails to be authenticated. The resulting false positive and false negative rates are 9.6394 1013 and 3.0982 1012, respectively, assuming that the inter-device and intra-device variabilities follow Gaussian distributions (Supplementary Fig. 14). The pairwise comparison map of cross-HD analyses further shows that all of the 30 different PUFs are highly uncorrelated (Fig. 6d) where the diagonal line indicates the intra-HD values for the identical PUF device itself, while the off-diagonal points represent the inter-HD values compared with the other PUF devices.

In fact, William %R, like all momentum indicators, is a lagging indicator - meaning the indicator level changes as the price of the stock changes.It ranges from 0 to -100. Usually when a reading is less than -80 the stock can be considered to be oversold, and when the reading is above -20 the stock can be considered overbought.

Show that $R$ is a division ring.Well, it's been a month, so here is the argument I had in mind. By assumption $R$ is simple as a left module over itself, hence every nonzero element $r in R$ has a left inverse $s$, thus $sr = 1$. But $s$ also has a left inverse $t$. Hence $s$ has a left and right inverse, which must agree, and hence $r$ does too.Showing $R$ is transitive and reflexive $to$ $R=R^2$, $R$ is transitive and reflexive $to$ $R=R^2$You need to distinguish very clearly between existential and universal quantification, and you should not use "let" when you actually want to say something about "any arbitrary given" something.Your first part of the first question should therefore be more precisely the following:If $R$ is transitive on $A$: For any $a,b in A$ such that $a R^2 b$: Let $c in A$ such that $a R c$ and $c R b$ for some $c in A$. Then $a R b$ because $R$ is transitive on $A$. Therefore $R^2 subseteq R$And here is the second part is in full:If $R^2 subseteq R$: For any $a,b,c in A$ such that $a R b$ and $b R c$: $exists x in A ( a R x wedge x R c )$. Thus $a R^2 c$. Thus $a R c$. Therefore $R$ is transitive on $A$

How Complicated Is It to Install Commercial Outdoor Pole Lights?
How Complicated Is It to Install Commercial Outdoor Pole Lights?
Everywhere you go there are commercial outdoor pole lights. They are so common, so numerous, that you probably do not even realize they are there. Every parking lot, walkway, and park you've ever been to is dotted with tall light poles. But if a pole light is damaged or missing, that's the only time when we notice the difference. After all, for many people, there are few things scarier than a dark corner of a parking lot. There are plenty of reasons why people need commercial outdoor pole lights installed. Whether you are developing a new property or need to renovate an existing one, new pole lights can transform your parking and pedestrian areas. So exactly how complicated is it to install new commercial outdoor pole lights? Here are a few things to consider from Atlanta's outdoor lighting pros. The town or city your property is in has a say about how tall and bright your pole lights can be. If the property falls under the jurisdiction of a homeowner's association, you could have a second layer of restrictions to navigate as well. So before you go buying a bunch of new lights, make sure you understand the limitations placed on your property. Nobody stops to think about the varying conditions pole lights are exposed to around the world. Not every pole light is built to withstand the extreme cold of Minneapolis, the incredible heat of Phoenix, or the frequent earthquakes of Los Angeles. Take the time to do your research and find the outdoor pole lights that are built to tolerate your local conditions. With these pieces of information in place, you can begin to narrow the field of possible pole light purchases. This is the time to start considering the affordability and aesthetic appeal of each of your light pole options. Once you know the brightness and spread of your pole light bulbs, you can do a little math. Sketch your outdoor lighting schematic to figure out how many light poles you need to purchase for your property. Again, your local ordinances and the light manufacturer's information will help you decide where the poles should be placed to provide even, optimal lighting. The next thing to check is the integrity of the pole light installation sites. The concrete or asphalt surrounding the install site should not be crumbling or cracked. You will need to dig an 18-inch deep hole, approximately two feet across, to pour the concrete footing that will support the light pole. (Check your local building codes for accurate specifications in your area.) Once the concrete is poured, the pole should be inserted immediately into the wet concrete. Use a crane to hold the pole straight up until the footing dries. Use levels to make sure the pole is perpendicular to the ground during the drying process. The last thing you want is a crooked 25-foot-tall light pole on your property! Also, this is one step of the installation process when you definitely want a professional's assistance. Wiring the new pole lights is often easier when old pole lights are being replaced. The in-ground wires are already installed. Assuming the existing wiring works, this will save you a lot more excavation and billable hours of work. If the lights are being installed at a new or extremely old development, new wiring should be laid down. Alternatively, you could install solar lights, which do not require any wiring. Make sure the lumens produced by these lights meet your property's requirements and your local ordinances. What Happens When Pole Lights Burn Out? This is inevitable for all light bulbs - well, except perhaps the Centennial Light, which has been burning in Livermore, California since 1901. But your new light poles will definitely require service down the road. When this happens, call an electrical service provider you trust to change out bulbs and perform other routine maintenance.

The rechargeable batteries in the lights have a shelf life, and time and temperature extremes have probably exhausted them. Try a new rechargeable battery in one light and see if it does not correct the problem2. list some advantages and disadvantaged to solar power?There are many advantages of solar energy. Just consider the advantages of solar energy over that of oil: Solar energy is a renewable resource. Although we cannot utilize the power of the sun at night or on stormy, cloudy days, etc., we can count on the sun being there the next day, ready to give us more energy and light. Oil, on the other hand, is not renewable. Once it is gone, it is gone. Solar cells are totally silent. They can extract energy from the sun without making a peep. Now imagine the noise that the giant machines used to drill for and pump oil make! Solar energy is non-polluting. Of all advantages of solar energy over that of oil, this is, perhaps, the most important. The burning of oil releases carbon dioxide and other greenhouse gases and carcinogens into the air. Solar cells require very little maintenance (they have no moving parts that will need to be fixed), and they last a long time. Although solar panels or solar lights, etc., may be expensive to buy at the onset, you can save money in the long run. After all, you do not have to pay for energy from the sun. On the other hand, all of us are aware of the rising cost of oil. Solar powered lights and other solar powered products are also very easy to install. You do not even need to worry about wires. And here are the disadvantages of solar energy: Solar cells/panels, etc. can be very expensive. Solar power cannot be created at night. As you can see the advantages of solar energy create a much longer list that the disadvantages, and the disadvantages are things that can be improved as technology improves.3. How do I replace AA batteries in outdoor solar lights with ultra-capacitor?Connect it the same polarity as the battery
Can Solar Lights Work in the Dark
Yes, the panels charge batteries that will allow it to work in the dark, until the charge runs out.. .Yes. They put out light in the dark of night and then they charge up when the Sun comes up.. .Solar lights collect solar photon energy during the day through their solar panel. This energy is converted into electricity and stored in the rechargeable (usually Ni-Cad) batteries. A photocell sensor detects whether there is sunlight available or not and acts to switch the lights on based on this. The electricity stored in the battery is regulated by a control board and, at night, the charged batteries provide power for the LED light. Once daylight returns, the panels repeat the process of charge.IBM Thinkpad T20, I want to use some car batteries... how would I do this?If you want longevity but not portability, please plug in the power cable to the power socket. You can run the notebook until the power to your home is cut or your notebook dies. But to answer your question directly, I do not think it's a good idea.How would i power multiple guitar food pedals without batteries?Yes. there's pedalboards and boxes which provide power for multiple pedalsHow to use car batteries for breadboard projects?THOSE SMALL LEAD ACID BATTERIES FROM YOUR LIST CAN PROVIDE AS HIGH AS 30A CURRENT WHILE ACCIDENCELY SHORT BOTH TERMINALS. BURNING THE BREADBOARD WITH SUCH POWER SOURCE AS FAST AS IN SECONDS. UNLESS, AS A SAFE WAY TO USE THEM, INSERTING A 2A FUSE TO LIMIT ITS CURRENT BEFORE LINKING TO BREADBOARD POWER INPUT. THIS WAY, FUSE BLOWS AND CUT OFF 12V POWER IF YOU MAKE MISTAKE ON BREADBORAD CIRCUIT. 12V CAN BE CHANGED INTO 9V POWER SOURCE BY USING A SIMPLE VOLTAGE REGULATOR IC CALLED LM7809.How the batteries in the vehicle recharged during moving?Your vehicle has an alternator, this is similar to a generator. As the engine spins, it drives the alternator which sends power to the batteryiGo electric screwdriver batteries type?if it takes batterys then u should be able to open it some how and then u can tell just on size alone and normally its written on it but if u see a hole in it some where than it probably is a rechargeable driver then u need to find the charger and its not a good idea to open itDoes brand matter for AAA batteries?not really.. but some brands are better quality and will last longer than othersAre my batteries safe to use after I made their contacts touch each other and it triggered a sound and a smell?If was just accidental short circuit then you just release some watts in the atmosphere. You should do a watched full charge. Anyway the charge controller should tell you if is gone. If it is not, carry on and be more careful next time. If they got hot then you just damaged them and you should replace themHow long will these batteries last if the radio has a resistance of 200 ohms?I came up with the same formula as Bill but with 133.3 minutes rather than hours: 240 / .03 = 8000 8000s / 60s/m = 133.3minutes = 2.22 hours Interestingly, the article below (quoting another article!) states: "The amount of charge that travels through a typical alkaline AA battery is about 5 kC = 5000 C = 1400 mAh. After that charge has flowed, the battery must be discarded or recharged." If that were true, we would have 4 * 5000C / .03C/s = 6.67E5 s = 6.67E5s / 3.6E3s/h = 185 hours = 7.7 days. .Solar controller with BJT transistor and PIC24 microcontroller to charge 3.6V NiMH batteriestl,dr: In your case, you do not seem to need charge control at all, and it is more complicated than you seem to sink because of various reasons. Just put a 1N4001 between the solar cell and the battery.The NiMH battery is a quite low impedance, pulling as much current from the solar cell as available at the cell voltage. During charging, it is likely around 1. 4V/cell. This is an output voltage of 4. 2 Volts, so in bright sunlight, you likely exceed the 170mA quoted for the maximum power point, expect something like 200-220mA, which is below C/10 of the cells. I have no idea how you want to do NiMH charging control at widely varying charging currents that never exceed C/10 (no -deltaU, no dT/T seems applicable, but let's ignore that).First thing to notice: Your circuit will not work as drawn. You drew a NPN transistor. It needs a voltage at the base that exceeds the emitter voltage (by around 0.6V) to make it conductive, but the uC has no access to provided the needed 4.8V (battery voltage 0.6V). You need an PNP transistor instead. In that case, you need to to provide current from the base terminal to a more negative sink. Also, you would connect the emitter to the solar cell in that case. Note that to turn off the transistor, you need the base voltage to go up to 0.5V below the unloaded solar cell voltage, this is around 8V. Start with the desired collector current (220mA maximum cell output) and take a look into the transistor data sheet. Let's choose a BC327 for it's higher current rating compared to the typical 100mA transistors. Take a look at figure 4 (Saturation region) if you want to have low losses on the transistor, which seems like a good idea now (but see later). They have curves for 100mA and 300mA collector current. As we do not have a lot of energy to waste, choosing a base current at the low end of the neary flat end of the saturation voltage curve is a good idea, which yields something around 4mA if you interpolate between the 100mA and the 300mA curve. To turn in the transistor, at 4.4V solar cell voltage, 200mV transistor drop, and 4. 2V battery voltage, you need to sink 4mA at 4.4V-0.6V (emitter-base voltage). To turn it off, base must rise to 8V (see above). This means, you need a pull-up resistor between base and emitter, providing the turn-off voltage from the cell instead of the uC and a diode (1N4148 will do) to protect the uC from that high voltage. So the circuit looks like this: PNP with emitter to solar cell, and collector to the battery. A resistor connecting emitter with base (the value does not matter much, and something around 100k will provide enough pull-off effect without disturbing the circuit while the transistor is on), a diode and a resistor in series to the uC. The uC needs to sink 4mA to turn the transistor on. This results in an output voltage of 0. 4V. So the resistor has to sink 4mA while having 0.4V above ground on the uC end and 3.8V above ground on the diode end. 4mA at 3.4V is 850 ohms. So 900 Ohms in your circuit does not seem off that much.You will not be happy at all with that circuit for different reasons, though: Constantly sinking 4mA takes too much of the charging current (getting 220mA outdoor on a bright sunny summer day is one thing, on cloudy days, being inside, expect something like 10mA maximum), and you are wasting 4mA of that just to turn that transistor on. Furthermore, when it gets dark, the solar cells draw power due to their leakage current and discharge the battery by operating the transistor in reverse mode (collector acts as emitter, base current is provided by the solar cells and the 100k resistor meant as pull-up, and the emitter acts as collector). Common wisdow is you need to protect against that, for example by putting a diode between the collector and the battery. You will lose voltage there, though. Another possiblity would be a "secondary pull-up" that will pull the base up, even if the emitter supply (the solar cell) fails to provide power, by connecting a resistor from collector to the base terminal. This resistor has to be low enough to pull the base up against the 100k that pulls it down, so go for something like 20k there. Of course adding all these resistors does not make the thing more efficient.Actually, your charging current is very low compared to cell capacity. As estimated above, you only get to C/12 on extraordinary good conditions, you the charging current can safely be considered as "trickle charging" unless you put the device into the beam of a bright headlight 24/7. You do not need any charge control. You just need to prevent discharge through cell leakage, and this can be povided by a single diode between solar cell and battery
