I got a new PC board from radio shack and I am going to be making a little flashlight.  I don't think the board is interconnected in any way, so is it ok for me just to use melted solder as a lead from one spot to another, like connecting the pos and neg of two led's.  If this isn't right, what is the proper way to use those PC boards.

Bypassing a multi function controller

I have just bought a laser nebular disco thingy off ebay (incorporating a red and green laser) - and whilst its works fine, I don't like the fact that it switches between various modes automatically (flashing, steady, red only, green only etc).  I opened it up to get some pictures of the circuit board - and wondered if anyone with knowledge of electronics could point me in the right direction with regards to bypassing the multi function controller on the circuit board.  I just want both lasers to remain on all the time. Thanks

electronic numeric display board for volleyball

I have searched the Internet hard for a reasonably priced electronic numeric display board to no avail.  I am interested in constructing a remote control scoreboard for volleyball similar to basketball scoreboards deployed in high schools.  For many years I have played and continue to play a LOT of drop in volleyball at various local Rec Centers.  It would be great to be able to keep track of the score with a remote control device in your pocket while playing the game. Alternatively please let me know of any high schools being torn down which could be an opportunity to save a basketball scoreboard that would otherwise be relegated to a land fill site. When you think about the utility of such a device, why hasn't this project been done before?  Maybe it has and if you have any info then PLEASE forward.   I would seriously entertain any posted price for such a completed device if it exists as the hero factor is huge.  The advantage of building it yourself is that you are in a position to manufacture duplicates for others and you become the repair man. The bigger the display board, the better.  I know they exist but are mostly cost prohibitive.  At this point I am prepared to start with a small display for the prototype in order to get this project started since I am very enthused.

Slow orangeboard - not a bug, though.

There was a good idea in another topic to use your OrangeBoard as a note-pad for on-going projects. That reminded me: My orangeboard is very slow.  It's not a bug, it's size (1100+ comments). Is there any way of speeding it up? Apart from going through all 1100 comments, deleting them one at a time, that is...

How can I build button panel that produces sound clips? Answered

I am tying to build a panel with approximately 30 buttons (I would like the buttons to resemble door bell buttons). When a button is pushed a sound clip is played through a speaker. I would like one sound clip assigned to each button rather than a random sound clip. If the sound clips were randomized there would be no need for all the different buttons. The large panel of buttons is an esthetic that is important to this project. Thank you for any advice.

Can a board be bypassed? Answered

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.

Thinking of organizing an online site with various breakout boards. Would people be interested?

Hi everyone, I have been thinking of starting up a website with a variety of breakout boards available. What I'm talking about is basically small PCBs with pins, where you just solder a chip on, and have all the pinouts available to connect things to. You know, regular breakout boards. Variety of chip footprints (tiny ones, big ones, through holes, surface mount). You could buy pin headers as well, or just buy the plane board. Would you personally see use in something like that? Since it would be breakout boards, shipping would be cheap (they're just flat and could go in an envelope). How much would you (if you were to use this type of service) would be willing to pay per board? Thanks a lot, Catsunami :3

Velleman sound-to-light kit

A Velleman sound-to-light kit (Radio Shack MK103) is a small circuit board powered by a 9v battery which lights LED bulbs when an audio signal is received by the microphone. I would like to connect this board directly to the headphone (output) jack of my audio device (metal detector), thereby bypassing the microphone input. This would allow visual operation of the detector without the use of headphones. When an object is detected it would illuminate an LED as opposed to sending an audio signal. Is it possible to de-solder the microphone on the circuit board and solder in a 3.5mm male connector which would plug directly into the audio output device? I have never worked on a circuit board before and I have ZERO knowledge of electronics, but the kit is only $8 - so I think it's worth a try - if the electronic wizardry is correct, that is. Thanks in advance for any help! -Bruce
