Would you need an additional microcontroller, such as an arduino, or could you control servos and lights directly from the IO-Bridge module?

Please Help! I need to make a bridge rectifier for a shake charging flashlight which also include using a 5V regulator - so it won't be a very high voltage, if that matters. What type of diodes do I need for this bridge rectifier? HELP! thank you! patti :)

This bridge launching robot by Flickr user Mahjqa is fantastic! The curled up bridge on its back is extended out up to 48cm (19 inches) over a gap before the robot disengages from it so it may drive across. On the other side it can turn around and pick it back up! [Youtube via Gizmodo]

Hello, What is the best way to construct a model bridge out of small wooden icecream sticks The requirements are as follows: 1) the icecream stick dimensions are 2mm deep 10mm wide by 115mm long 2) the bridge has to be 1 metre long and about 20-30cm wide 3) the only materials are the wooden icecream sticks , wood glue and cardboard to form the deck of the bridge. The idea is to construct the bridge so as to be able to hold the most weight.The most weight achieved so far is 450 kg before breaking

I'm making diode bridges to have a nice supply of DC. I'm making a high voltage bridge for a 7.5kv nst and a low voltage bridge for regular 120v wall outlet . My high voltage bridge im going to make with several 1N4007 but i read that they should be "shunted" with 10Mohm resistors im not sure what is meant by this. Does it mean resistor, diode, resistor, diode or does it mean diode and resistor, diode and resistor. The pic says it better than i do. Also, do i need resistors for a bridge for 120v bridge?, im going to use the diodes from a fluorescent light power supply.

Every textbook, reference, and manual I have or can find say bridge network so where does H Bridge come from. I do know that bridge circuits can look like an H the way some people draw the schematic but they are called bridge networks whether they are resistors, diodes, capacitors, transistors, or a mix and look like an H or not. Other than a hand full of dictionaries and the books I have written and anthologies my works are in on top of this books case, all these books and more that I have are on electronics and none of them say H Bridge. So I would like to know where H Bridge comes from and please post the book or competent reference. Joe

My LCR meter can only read inductances of mH to a few Henries. I need to make a 470uH inductor, since in my place inductors are not so common. How can i measure inductances at microhenries if my LCR meter's reading capability only ranges from millihenries to henries? Someone told me to use bridges like wheatstone bridge or maxwell bridge to have an accurate reading, but i don't know how to do it. Can you suggest any reference? I prefer doing wheatstone. Thank you in advance :)

Is it possible to make a transistor H-bridge with PNP transistors or can it only be done with NPN transistors. As far as my knowledge( or lack thereof) of transistors goes, I think it would be possible, but it would require more than 4 transistors and it would be much more complex, however I could be entirely wrong. Any input would be helpful, thanks.

Well, the question itself tells a lot (mostly how bad it's asked). I have a quad amplifier that i'm using as a stereo bridge. So is there a possibility to bridge those two (or parallel em?) This amplifier is not some factory made amp, It's a simple amp i made with TDA7375. The output is somewhere between 2x30 and 2x40W , but i'm only using one channel and it seems like a waste (I'm using it as a small woofer driver, didn't have another amp so this one had to do) So, The question is Is there a way i can make this Mono so i can get some more power out of it (or just use both channels so i don't only use one). The amp is TDA7375 and the speaker is Novex sps250i (yeah, it's crappy but sounds decent) Also it says nowhere that this one can be bridged to mono. Also won't it work if i parallel two channels and then bridge them to mono? (as in parallel four into two then bridge those) From what someone told me if i want to parallel it i'll need some 0.1ohm 5W resistors (those are really cheap and easy to find here) Thanks in advance.

HiIn the fit test I realized my printer (a Printrbot Simple) did not make the bridges for the holes very well. There are stringy parts hanging down from the ceiling in the holes at the sides. It is a bit difficult to see from the pictures. The stringy parts are affecting the tolerance when using overhangs or bridges. Of course I can sand it down but is there any tips on how to get better results from the printer?I use Cura, by the way.

I need to design a bridge for a project but it has to be made out of MDF that is 20cm x 33cm x 3mm MDF that is 3mm x 3mm x anything hot glue and string. It has to be strong, span 60cm have a 30cm clearance and be 20cm wide. It can have no supports and not attach to the ground. The wide MDF can only be used for the road and you cannot layer it.

I want to build a foot bridge across a creek! The width of the creek is 16', but I'm going 24' long to support the footers. The bridge itself will be 4' wide. I was thinking of using "C" channel iron welded onto I-beams to hold the treated 2x6's in place. I need info on what type and size of beams, etc. If it's not too obvious I'm a complete engineering noob, but this is the kind of project that makes country living worthwhile. Thanks in advance for your kind help!

The characteristic sound of a sitar is created by a bridge that gently rolls away from the strings; this creates a buzzing timbre which quickly depletes higher overtones in the string's vibration (I could draw some diagrams if anyone's interested). This type of bridge is something I'd like to make as a removable modification for a guitar. My guitar has a "floating tailpiece" as I believe it's called, in which the strings pass beyond the bridge to the tailpiece. The segment of the strings below the bridge have no part in tone generation, and so could have an object attached to them (a piece of wood wedged between the strings, perhaps) without affecting the guitar's tone. If some object (the "clamp") were attached to the strings immediately below the bridge, another object (the "sitar bridge") could be affixed to it some minuscule distance from the vibrating portion of the strings. The sitar bridge would not make contact with the strings at rest, and so would not be a node of vibration (and not affect the strings' pitch), but when the strings are played, their vibrations would make them rattle against the sitar bridge - much like the bridge of an actual sitar. So how about it? I think it'd be an interesting and relatively simple mod that could be made to be removable and not destructive at all to the actual guitar. I unfortunately have no idea how to refine the concept any further than what's written, so I leave it up to any willing DIY-ers. It all makes sense in my head, but I may have accidentally left out some important particulars of this kind of mod, so please ask any questions you have. Because this mod relies on the strings below the bridge in a floating tailpiece guitar, I don't think it would work on most solid-bodied guitars, but if anyone can come up with a similar mod for the more common bridge type, be my guest. Also remember that the "clamp" below the bridge cannot rely on the tensile strength of the strings, as not only are they not terribly strong, their tension needs to remain intact so that the guitar can be played in tune.

I am confused about the H-Bridge...I unfortunately just soldered the H-Bridge as mentioned in the example. I thought it is already the soldering for the Skitterbot. So the motor is only going in the other direction when I toggle the switch. you then solder it together in another way, right? I can't see it properly and I guess my english is not the best.red and black wires of motor and battery are not in the same line, right?Thank you!

If I use a bridge rectifier to convert AC 110V into "DC" 110(154V), I'm guessing the amperage rating on the rectifier is how much current will be available to use vs the voltage being output as well? The reason I put 154 volts is because peak voltage is 110ac times 1.4. I'm using this for LEDs, just to provide some more info. The bridge rectifiers I have are rated at 200V and 1.5A.?

It basically has two large screws, one on either side of the bridge, If anyone is familiar with this style of adjustable bridge can you please either tell me how to use it or send me a link to a site that will? the action is pretty low on the high strings and I'm getting a lot of buzzing (more than I should). Thanks for any help you can give!

Hello! I'm a bit stuck on making a stable, theoretical bridge. Rules: No one piece can be longer than 10, no shorter than 1. The bridge must span at least 8. Imagine a gully: \______/ There are three anchor points that you must use on each side - the highest is at the top, the lowest halfway down (not that that makes too much difference...). You have 80 pieces with which to build your bridges - please can you lend me your noggin's as I'm having trouble coming up with ideas that will bear a load. A regular suspension bridge or a tressle bridge won't work, as the joins for the pieces are not fixed solid - so you must use triangles / tension to support them. A bit like loose mechano, or whatever it is people have these days :7) Do they still have lego? I haven't seen a kid play with lego for ages... It's mostly P£3 and Sega Megadrives and stuff. tsk. Thanks! Claire. [ed] I just noticed a knex catagory. I guess that's mechano, right..?
