Hey all, Today I bought a PC board (printed circuit). I plan on making a flashlight with it and some 10 mm LED's I have, but I need some info on how to use the board. If I have a PC Board, how would I put the LED's on the circuit board for all of the lights to show up at once. (hence the flashlight). If anyone could diagram it out, or tell me a good way to do this, it would be really apprciated. Thanks a ton, Nicholas Brenn

I recently saw a show about extreme sports. This included mountain biking, street luge, and long-boarding (all of which I do) and it also showed mountain boarding. I had heard of it before, and I think that it would be very fun. But how much do they cost, and are they easy to use? I am willing to learn, but I cannot go out and spend $500 on one. Any info would be helpful, so please post! Thanks

I came up with an idea! There should be a place on the site called the "drawing board" in which you could sketch out ideas using your mouse and save them as a JPG. You could incorporate this into drawing plans and designs for your instructable! It could be a cool feature for everyone, but for pro membership you could have extra things (e.g. rainbow colors, a ruler, paint brush mode). I think this would be a cool addition to the website.

I have a shelf, about 2x2 feet, (not attached to anything) that I use as a work board for my projects. I'm thinking about adding some things to it, like built in helping hands, magnets for holding tools while i'm working, a light, etc. Do you think it would be worth making an instructable about?

I need to make a circuit board for a project. It is all 12vdc, I have a 1a fan and a 6a thermoelectric device one setting 1, plus another 6a on setting 2, and a 3rd on setting 3 So 1 is 7a 2 is 13a 3 is 19a How to make the board. Also a second device has the 1a fan plus a 4watt element, plus another 4w on setting 2, plus another 4w on setting 3 So 1 is 1a and I think 0.4a= 1.4a 2 is 1.8a 3 is 2.2a. I think

Hi. A basic question; I need to connect a breakout board to a strip board. What is the best method? PCB Latch plug header? I have tried putting a wire through the strip board, through the breakout board and then soldering into place, but I do not get good connectivity. Any help is much appreciated.

I have a Sony hcd-fx10 dvd home theater system, and one day I turned it on and it went into protect mode. I contacted Sony and they said it needs to be serviced. I found a service manual online and took the unit apart. I consider myself handy, so this was not a problem. Upon further investigation and with use of the service manual, i found a brown burn mark on the bottom of the motherboard, which corralates to the protection detection module on the board; which is my prblem. My question is, Can I simply remove this module, or does it need to be replaced with a new one or something similar? I don't know much about circuitboards but have some skill at soldering. Attached are pictures, the best I could get of the small board, showing the actual module on the board and the burn mark on the bottom of the board. Any info would be great. Thanks.

I've been looking around the web trying to find a place that sells ready made circuit boards, plated and pre-drilled; like what you would find in Radio Shack but with a larger selection. I've looked at Mouser and their selection is rather limited. What I need is a circuit board about 1" square for mounting tactile buttons on it. Like I said I've been looking all over and all I can find are websites that make custom circuit boards, but nothing already made. So anyone know of a place where I can buy already made circuit boards?

I am into electronics, but have had to use pre made PC boards. there is nothing wrong with this, but it can sometimes be inconvenient, and more difficult when the time comes to put the circuit board together. I have seen instructables on how to make custom printed circuit boards, but they all used laser printers. I do not own a laser printer, and cannot really afford to buy one. Is there a way to etch boards without a laser printer, and if so how?

I am making a bow and arrow rack I saw in a magazine. They want $50.00 dollars for it, plus shipping. So being frugal, I have plenty of dead cedar logs around for projects, I will make my own. I just can't seem to come up with a way to hold the logs (28" L x about 10: D) . Anyone got any suggestions ?

I am working on a DIY thumb drive. I want one Flash drive sticking out each end of this casing. The two circuit boards will be nearly touching, nested, one on top of the other in opposite directions. Should I be concerned, should I put something between them?

I have a Samsung laser printer. Many of he PCB board designs found on he internet are only simply image files and are not associated with a specific PCB design program. My question is what free mage software is available to print an image of a PCB board to scale. Thanks for any help Bob T

I built a generic board for pic18f452 microcontroller. But i am not sure if it is working or not.it is getting Vcc=5Vits reset button is working(i.e gives 0V on pressing)i want to know about how to be sure that this generic board is built correctly.
Question by asif.haris21 | last reply
I'm looking for a board (for the moment a development board would be the best solution as I am prototyping) with NFC and WiFi integrated. I saw that Arduino should launch one with NFC, Wifi and Bluetooth, the board is called Primo. I can't find anything else and Arduino can't announced a date for the launch. For now I'm working with a NFC reader and the Arduino WiFi Board both mounted on a separate Arduino Uno because the two boards are incompatible. Any idea ? Thanks Alizée

I want to build a LED writing board. It's basically a markerboard with a LED light behind it and it takes advantage of special fluorescent markers. My question is, how can I achieve that the board doesn't light up unless the marker is applied to the board. You can see in the video, that the glass stays black/dark until you write on it... How does that work? http://www.youtube.com/watch?v=pQwdWvGIq5A

I have this circuit board which I pulled from an iPhone dock. When I look at the bottom, it seems obvious where the wires and connections are running. Does this mean that the area marked in the photo below is fair play for cutting and removing without effecting the functionality of the circuit board? The project I'm working on would greatly benefit from being able to remove a small part of the plastic.

Question by Adarsh_tronix | last reply
My sewing machine (a Pfaff 1171) dies after about 10 minutes. When I push on the peddle again, there is nothing... no hum - absolutely nothing. The light stays on. Wait fifteen minutes or so, and it runs just fine...only to repeat the cycle. Turning the wheel doesn't change the electrical situation. It's almost as though a fuse is blowing and then resetting itself. I took it into the shop, and the verdict is that it's either the peddle (unlikely) or the board inside. The board is no longer made. If I turn the wheel, everything works... forwards, backwards, stitches and all that. It's a great machine mechanically, and I hate to lose it because of some glitch on a board. Is there any way that a board could be bypassed? I can survive without a bobbin sensor and being able to set whether the machine stops with the needle up or down.

I made two cutting boards and apparently I did a bad job cutting it or the wood was too roughly cut or something, I don't know, but now they both have gaps in them. I glued one up, and the other one I didn't but could tell it was going to be the same. Is there any way to fix my goof, or if there is not, what is another project that I could use the wood for as to not completely waste it? Thanks!
Question by schoonovermr | last reply
Hi there. I salvaged 2 boards of LEDs from an old LED can at work. They were previously DMX, and have an array of red, green, and blue LEDs. There are four leads coming from the board, +, -, a dashed line, and an unmarked line. I am looking to integrate these with another project, but am unsure how to go about finding how to control them electrically. I was thinking it might be digitally controlled right on the board, but I see no IC. All I am looking to do is figure out where voltage needs to be applied in order to have different RGB levels. If I helps, the number printed on the board is FT140PCB GS. I am able to attach an image if that would be helpful. Any ideas of how to go about this? Thanks a lot, anything would help!

Just harvested a ballast board along with the lamp out of a rear projection tv and was thinking about making a Jacob's ladder with it since it outputs a suitably high enough voltage. My only problem is bypassing the 'power on' signal to the circuit to instead manually switch the lamp on and off. Does anyone have knowledge of the circuitry that would allow me to accomplish this?
