Fantastic! This is exactly why I posted this. Great information! This is why I love this forum. I will definitely spend some time looking into polar relay circuits today. Whenever I see a -X, +X voltage the thing that springs to mind is op-amps.

Well thats a lot to go over. Your primer, Garth, is mindblowingly dense. My biggest initial question is why did they use -10 to +10v?

I bought a box of assorted SMD parts on eBay about 15 years ago and I'm just getting around to figuring out the identity of some of the buried little bags of ICs. I wanted to bring up one that I found in hopes of sparking a useful discussion for other newbies because I was bored.

The chip is a ...

Bill Mensch asked me why hobbyists aren't picking up the 65265 much, and I said it was undoubtedly largely because the speed rating is so much lower. He responded, "Well, it may very well go a lot faster, but we just never tried it." I don't understand that logic, since hiding virtues is not the ...

This reminded me of something that has been bugging me ever since I bought it. I got one of those 'helping hands' thingies with the assorted magnetic arms and pegs. Its absolute garbage btw, the pegs are fine because they are just cylinders machined to a tip, hard to mess up, but the arms have weak ...

Seemed like a silly question but it just jumped out of the screen at me so I had to ask I really need to get a scope. There really is a wall you run into eventually where you need to see what them darn electrons are doing.

I'm laid up in bed with a killer migraine today so I will mess around with this and see if I can crash it or break it

LMAO 40GB? It better have an oculus rift version that you can run around through the logic gates and edit it with your hands. Yikes. Sounds like a typical company sitting comfortably on a near monopoly. Many such cases, sad.

Of course I can't find mine now, but when I do I will update you on its performance

I don't have a scope and I'm not sure how you have yours set up but is your reset signal reading 50+V? almost 80Vpp??

sweet! i have a really old ipod touch just sitting in a drawer ill have to see what version of iOS its running.

Walking into this forum and asking a question is like walking up to Jimi Hendrix and asking him how he 'does that one solo thingy, the WEEDLY WEEDLY WEEEEEEEE!!!!' Sometimes I beat myself up for knowing almost nothing and being such a newb but then I remember most here have been doing this stuff ...

NICE!

I've fixed the intermittency issues and also moved the entire design over to protoboard. I can now get consistent LED readouts on all button presses even when mashed and i see significantly less flutter in the LED's during press/release phases of the keypress. I still can't get the LCD to print ...

I have been extremely careless with most of my stuff and have never caused any static damage. In my wide but shallow range of experience you are much much much more likely to hook something up wrong and damage a chip than to damage something from ESD. I melted 3 555 timers into a breadboard (the ...
