two wire rs 232 to rs 485 communication circuit
The hard part is where to get power for this. RS485 is a 5v powered differential 50 Ohm line driver RS232 is two [or more] single ended +/- 9v signals. Ok use a RS485 transciever chip to convert to/from TTL levels plus a RS232 I/O with at least 1...
Re: Hi all..am new here
INS-ANI had the best info so far the gate driver does 2 importent things it turns the driver on/off if it's a switch or controls how on if it's linear [never off], the 2nd job it does is to prevent changes in gate/drain voltage from affecting gate/source voltage since a...
home brew etchant
So you basicly want a very small plasma cutter ? problem is it's hard to aim and takes a fair current at very high voltage but I can offer some help a discharge etch machine is fairly easy it's like plasma etch minus the bother just rip the transformer from an old tube radio...
Re: Inductor meter
It's cute but I think your barking up the wrong tree. Try using two of those amps and a cap to make a L/C oscillator use a much smaller fet a diode and a R/C to make the gain of one amp drop as voltage increases and two R's to fix the gain of the other amp. You should get a...
