PC Board

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

Mountain Boarding?

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

A "Drawing Board"

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.

Circuit Board Help

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.

Looking for pre-printed circuit boards

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?

Making printed circuit boards without laser printer? Answered

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?

Arduino PCB Board Layouts

I thought I might share some the circuit board layouts (Top and bottom) of several Arduino boards that I've created. They could be used to etch your own board or just used to compare sizes.

Computer Circuit Board Identification request

Here are a few pictures of two boards I have (I am not sure how old they are, but they either came from my old 8088/8086, 286, 386, or my PS2 (all long gone now). What I need to know is what they are/were and are there any specs out there (I can't seem to locate any): one has a port on the side, one does not. The one without the port has a T.I. chip that looks like an IR programmable PROM with PGM=12.5 v on it. There is also a crystal with 24.000 stamped on it. The other one it probably an old video card but it has only 4 resistors on it and one resistor bank, plus four capacitors, and two ic's. One is labeled: 74LS245N ( Octal Bus Transmitter/Receiver designed for 8-line asynchronous 2-way data communication between data buses ), the larger IC is an unmarked 40 pin device. I tried for half an hour to get half decent pictures of them, sorry for the quality.

Arduino BOARDs.TXT messed up

I messed up a bit in the boards.txt... I suppose. I added a few extra's for ATTiny, ATMega... And now I get some errors, but I can still program. I think it came by installing newer updates over new updates from the IDE. A little time ago, you had to be sure to copy your "not standard" libraries to another place, before making updates of the IDE, it looks that now you don't have to anymore. But I keep fighting the BOARDS.TXT Can anyone help me, how I get it right again?

Board with NFC and WiFi

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

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.
