Pinout Question

Lol! Nice soldering iron you have there (I have the same one). I won't buy anything but Weller after using them in school. Ben even liked mine enough that when he was actually removing EPROMS and soldering in new EEPROMS that he bought a Weller as well. I like your setup

I see he has a sling shot target on the desk as well

My Weller is older than me. I would like to have one with the thermostat on it, mine has been beaten around so much that I really don't think the controlled output is so controlled anymore, and it overheats lately. Been using the cheapie. Even built the wideband controller with the $10 pce of garbage, but at least it holds a consistent temp for the most part.

Dave, I'm surprised you don't have a stim of some sort. I don't know how hard it would be to fab up your own, but have seen them fairly reasonable.

I just want to know what the signal turns out to be

Is that a bag of charcoal in case you need to burn something?

lol..

that's how i test how bright my flashlights are, if i can get the charcoal to smoke they're doing good..

Let's see if they can make this lithium battery smoke...

My wife thought that was a cigarette burn in my chair from when that battery blew, lol. And here I was looking at that bag thinking it looked like a bag of cat food...

MY wife wasn't happy about my burnt chair either lol. All the stuff we put in the fire (including the nitro), and the thing that did the most damage was just a plain old empty water bottle that was sealed

I'll look at that tomorrow...

here is my home bench:


Tektronix color 2 channel 100 MHz scope, DC power supply load tester, variable DC supply, 3.5A 13.8V DC supply, 13.8V 20A DC supply, Viz generator (old school) and some other stuff.

Most of the time i build custom flashlight stuff and repair car amps at home, it's nice to start fresh with a project

You nerd... I don't see one mechanical engine part on that bench... Just a bunch of little kid sized tools... LMAO

I'm starting to get anxious... I'm closing on my house in 3 days and I'll finally have a bench that I can make my own!!!! YAHOOOO!

Maybe probe the plugs on an ICM with an oscilloscope while turning an engine over with a starter to see what kind of signal it puts out? I don't see why it wouldn't be a square wave, but for all we know, it's sine or sawtooth.

I was working on this over the winter while I was building my engine. Here's a post over at code59 that I started. Oscilloscope stuff starts half way down.

I gave up once I started putting motor back together. That and I blew the sound card on my laptop trying to simulate the signal with a signal generator.

It was D8 and D9, i must have had a bad connection before. I soldered directly to the ecm and now have full RPM range. It seems to like a sine wave better than a square wave.


300Hz = 6K RPM
