Title: Stable Gated PWM by Electrojolt
Post by: Login to see usernames on June 29, 2009, 01:45:20 am
All,

I've had the good fortune of building the stable gated pwm on Electrojolt's pcb.  The device is now my test workhorse and I understand has some very recent circuit upgrades according to the designer.  I'll admit it required skillful soldering.

Control is smooth and pulse width is stable through frequency sweeps .  I  may deadbug one just for rougher testing.  The pcb has useful ports designed in at points in the circuit and can hold six fets.

My complements to Electrojolt, if I had not found him on youtube I'd still be trying to modify a triple 555 circuit used for electrotherapy in skin contact devices.  Pulse train with gated space and frequency control was featured in the circuit I had found on the web for body stimulation, yet his circuit hits it out of the park.   Simple and ingenious.

for about 100$ more , I think my circuit has a better value .

My logic was built to cover multiple possibilities that the Jolt circuit cannot do.

Greg,

I'm glad you like my circuit.

Dankie,

I'm not in business to sell my PWM.. It is Open source.

When you compare what you get get today for $250.00 bucks, there is no PWM worth that much.

for $250.oo you can buy a new computer, that has way more parts than any PWM.

Well I'm not about to give away my long frustrating hours for free right now

Both mine and yours are asembly @ home  .

there is a 100$ difference in the end and alot of features wich I think are important  .
