I made the original post because I've seen a few blatant advertisements (the most recent one wasn't even written well). I'm tired of expending the extra nanojoules of energy required to click on a forum topic hoping for a good read, and find a bloody advertisement. I, too, like the fact that there a...

Maybe there should be a separate forum for people to post their advertisements, special offers, and astounding deals. I know it won't stop blatant spamming, but it would be one spot for the honest guys to post their offers and whatnot. That way, if you don't feel like reading advertisements, you don...

My google spamming paid off. I found this part: http://pdf1.alldatasheet.com/datasheet-pdf/view/76759/MICROSEMI/SM1605C.html It's an 8-in-1 TVS IC. I assume you simply connect the signal to the input, and ground the output pins. Might need a resistor in there as well. BTW, one signal is just a digit...

I have a circuit in a piece of communications equipment that needs a bunch of signal lines to have TVS. I was hoping to find an IC that might accomplish this, as a minimum number parts is desirable. I am currently googling the hell out of this, but no luck so far. I am hoping someone out there has s...

Solved! I forgot to ground the negative supply voltage. It was floating, and therefore was picking up the 60Hz and injecting it into the signal.

It's homegrown for now, but the circuit is for work. It's on a protoboard (the kind you can solder to). It's 60Hz noise, and I have all kinds of wire-wrap wire everywhere. I guess it's all acting like a big antenna array. Hopefully it'll get better when it goes on a PCB

Strange... I just used for the first time the TechTools Digiview. I only needed to look at 3 signals, so the number of channels was plenty for me. Once I learned how the GUI worked, I really liked the tool. I've never used any of the other ones and this was my first day using this one, so I'm no exp...

This is a triple 2-1 Audio Multiplexer. I seem to be getting quite a bit of noise from it. I was wondering where the best place to put coupling/decoupling caps would be? Vcc and Gnd are already coupled (I have a uC in the circuit as well). Thanks for any help.

Yes wavelength depends on colour... or rather, colour depends on wavelength. I'm not sure what colours work best underwater, but if you think about it, all the phosphorescence found in marine nature is green or blue. Darwin would say that green or blue (which have shorter wavelengths than red or ora...

Hey guys. I'm researching some uC's for a project at work, and the HC08 family came to sight, specifically the MC68HC908QT1/2/4. I see that CodeWarrior is the IDE to use, but what about programmers? I found this: http://microcontrollershop.com/product_info.php?cPath=104_135&products_id=379 But I...

You could multiplex the pins. When you're not sending parallel data, RB3 could be an input. Then when you need to send data, switch it to an output. -- edit: Actually that's not a good idea at all. Don't do that <small>[ March 22, 2006, 07:13 AM: Message edited by: HighFrequency ]</small>

I usually "AND" my bytes. For instance: 10011010 I need bit 4. So I AND with: 00010000 Now everything other than bit 4 is -------- guaranteed to be zero. And the result: 00010000 Then just do an if (result). If anything is in result, it returns true which means your bit was set.

I am an electronics student in BC and I know I love getting my mitts on different chips and what-not. I recently sampled some Microchip RF devices, then realized I had no way to program them. Plus they're SMT, and I don't know how to program SMT chips. <small>[ March 15, 2006, 10:21 PM: Message edit...

Hey guys. The lady and I were watching a movie tonight, Domino. Not bad. We noticed at the end of the movie, the credits were in a fuzzy text. We thought that was pretty dumb. Anyhow, we left the tv on and I went to check my email, and she went for a bath. She went back into the living room to watch...

ummm... read the part number off the transistor case, then google it.
