While I can see where you're going with your argument, to think that the average person who's buying a PS3 in the UK is going to be looking to...
Well, I tried it with exact values last night and no dice. I also tried Zwox's circuit with similar results. It seems that only some of the LEDs...
Yeah, the resistors I used were a bit smaller as I didn't have the exact values handy, but according to the page, they're not really critical...
I'd like to build a circuit that will pulse a series of LEDs to obtain a twinkling christmas light effect. I found this circuit that I'm trying...
Well, not a ton of help, but here is the schematic for the Velleman K4300 10 band spectrum analyzer. It's been discontinued since one of the ICs...
Ahhh... that's definately a lot simpler than a fancy flip/flip!! See, now this is exactly why I generally come straight to Bit-Tech for my...
Okay, I know this sounds a bit strange, but how would I go about creating independant on and off buttons using momentary switches?? Basically,...
The thing is that their schematic is basically worthless since one of the key ICs isn't made anymore. I had been hoping to redesign the circuit...
Well, I will say that I had the same idea a few years ago. Actually, it was right before Mashie put the Velleman kit in his comp. He had a bit...
Okay, I've read throught the knight rider mod a couple of times and I've built a few simple circuits, so I figure I can do this one too. Anyway,...
Steve, On the glass of the LCD itself, there is a piece of polarizing film that needs to be removed. It is stuck on fairly well, so you may...
How might one go about amplifying a signal of around 50mV to something useable with an LM3914?? Thanks
Cool. Thanks a lot guys. My electronics knowledge was nil when I started this project, but I'm determined to do it on my own (a little help...
Yeah, I've been working on a 10 band spectrum analyzer based off of the Velleman K4300 kit. Unfortunately, the kit has been discontinued, and my...
Cool, thanks linear. BTW, how was the big move?? Oh yeah, didja get those bargraphs I sent out to ya?? Ya, its for a trimmer. See......
Okay, this is a strange question but... I'm working on a circuit that requires a 22K pot. However, I don't have any laying around. Could I...
Really depends. You're not exactly building a space shuttle or anything, so most multimeters will do the job just fine. Hell, I use this POS for...
Not a problem, I can figure that out with a multimeter and some math. Not sure exactly what you mean there. Are you saying that I should...
Okay, got a question. I'm working on a 10 band spectrum analyzer based of the Velleman K4300 (which has been discontinued). Anyway, I modified...
Mwah ah ah... LIFE!! Thanks guys, the problem actually wound up being that I had the transistor base connected to pin 6 on the 502 rather than...
