Hi Gary, and ya'll, (that is if anyone is still around) I'm Reuben in middle TN usa. I was homeschooled when very few were doing it back in the 70's, got most of my education from the Chattanooga public library up through mid 80's. I was/am highly technically inclined, got iinterested in steam engines when around 13, quickly went on to discover electronics and got into ham radio, for the electronics, I'm not a talker so hardly ever use a working radio. My parents sold our land in mid 80's and moved to a much larger more remote place, made me part owner, and I took up the job of harvesting the timber, got a sawmill. (sold it last spring and now I'm putting another one together) Done some farming, (will be doing a lot more to make a living and grow all our food) learned mechanics from a neighbor who was running a home based mechanic business, learned foundry from books, built a couple small metal melting furnaces and got some antique metal working machines. (cheap) Made a few machine parts. (was just making one yesterday on the lathe to fix a dozer) I started a 40 HP steam tractor project a few years ago, it got shelved for awhile, but I'm thinking of finishing it this year if I can. I enjoy horses and learned how to handle and train them.
But every now and then I go back and do some electronic experimenting or build a circuit when I need something. Have build several motor controllers with the 555 chip and a 393 for pulse width control. Made my own electronic ignition circuits for engines using both hall effect IC's and photointerruptors. I like the photo device better because greater timing precision is easier to get. My next one will be a capacitive discharge type I think. I've got my own idea for a circuit on that. I just got done putting together the electric fence charger instead of buying one for $100. It's working good. I like the multi spark pulses. Used an IRF740 for the power transistor. I think I'll put two ign. coils on it in parallel since I'm charging a twin strand fence around 5 acres or so to hold 4 horses. Has taken close to a mile of fence rope. (using the poly rope with stainless wires woven into it.) I'm running short on hay and have fenced in a section of hay field to run them in. Got a few solar panels laying around, I'll put one on a deep cycle battery with a charge controller and check on battery voltage every once in awhile during cloudy weather.
My agenda this year is to finish a land clearing project which will give us the equipment to clear some of our own land, (probably a couple months till that's done) get the sawmill put together. (it's an antique, pile of rusty parts now) put in some cash crops and plenty of food crops for ourselves. The cash crops will probably be 2 acres of cream peas and maybe an acre of okra. Possibly an acre of radicchio for a fall crop. And inbetween as I can find time, finish building that steam engine and boiler. I'll probably use a stainless steel pipe for the water level guage, (instead of a glass sight guage) put a magnet in a float inside it and use hall effect devices on the outside to indicate water level. Then it'd be easy to put automatic feed pump control on it for stationary operation.
Oh well, I guess I didn't need to give ya my history, I just wanted to thank you for providing the circuits.
Oh and since I never attended regular school, and did that before the age of computers, I'm not much good at running them. I got a bunch of malware on this one now and need it cleaned up, don't know how except to take it to a computer service shop and pay them to do it. The free avast doesn't seem to keep it out. RT
