yeah, they're quite useful. and push plenty of amperage for almost any DIY project.

i'm just using a fairly new ATX power supply.... had no use for it since i bought a ~800 watt unit, so this one got turned into my "project power supply"...

charge batteries, power a jewelry...

mine did it immediately after i completed it, so it's likely that i skipped a resistor or hooked up the pot incorrectly.

either way, it all fits in a 6" X 8" radioshack project box... and it is...

i'll have pics up tomorrow. :D

mine is currently functioning.... kinda. i'm having issues with the 3 wire sensors ATM, but i have a good idea as to why. turn A/C pressure pot, skews MAP and TPS...

RBob/Dimented24x7 have been guiding me along and it sounds like i have a good option cooked up now that will allow me to make somewhere between a square and sine wave for the O2, which is what...

neither of these options would make the O2 swing though.... just provide an static mV value until manually adjusted.



and i'm piecing this together bit by bit, since it will be incredibly...

so how is everybody simulating an O2 sensor? that's about my only holdup ATM.

i want to be able to control high/low time ratio and swing frequency independantly, so a 555 is pretty much out of the...
