    the electrical system here dates from the days of the rural electrification administration :o it was actually early 60's before they got it to this valley.  I've blowed many a fuse, even the hunnered amp ones.  and several have makeshift replacements.  I keep thinking I'm going to build a shop...

    How to Use a 555 Timer for PWM

    I did notice that,  the circuit i have runs at several hundred Hz with a lot of frequency change along with the pulse width change,  i ran a tape recorder motor with it, it ran fine from 0 to full speed, then put a  speaker on it to hear what it's doing.  I'll try this one and see if it does...

    interesting little project

    well,  yah,  i always have too many ideas, and not enough time or money to persue them, do have several inventors in my ancestry. not that arangment,  lol!  just using the small single phase as a starter for the 3 hp 3 phase motor to serve as phase converter.  a 3 phase motor will run on 1...

    electornics and communication

    that is a very broad field,  have to specify a little more what yer interested in.  I used to do a lot of robbing old TV's of parts and making simple shortwave radios, etc.  then there's all kinds of various communication types and methods one can play with.  like modulating a laser beam with...

    How to Use a 555 Timer for PWM

    ahhh!!!    thanks!  that's a better circuit than i the one i have,  I'll use that to drive the little power transistors that drive the really big ones that run the 15hp forklift motor that i installed in a subaru wagon to make a HE car.    RT
