Thanks.

Here is the schematic.

HI, I recently built a capacitor bank charger using parts from a camera flash circuit. I blew the little power transistor. So, could I replace it with any NPN Power Transistor. Thanks

I don't know a whole lot about electronics, still learning. So could you tell me how you determined it will be running at 440Hz.

I was originally going to go with the single 555 but didn't know if a single 555 could handle the four MOSFETS or more (and I have a lot of parts lying around:)   I'll go with the single 555. Thanks for the quick reply.

Hey, I'm working on a project and would like to know if this circuit would work. The two 50K potentiometers will be a single stereo potentiometer. Also the PWM's and the LOAD will be powered by different power supply.

Hey Guys,  Ive started to get back into electronics(after 2 years).  and I want to start with making a High Voltage power supply, and I dont quit remember how.  So could I use the PWM in the link to power a flyback transformer.

Hello, I have one of those plastic floor mats with the spikes on the bottom for my chair. When I'm working and go to touch my equipment i get shocked, I'm sick of it. Is there any thing i can do to eliminate this static. Ive heard if i put some aluminum foil under it and run a wire from it to a grounding point it will get rid of it, is this true.

I built the dual voltage power supply (http://www.electronics-lab.com/projects/power/039/index.html). But i made it 15 volts not 12 volt (7915 and 7815). But the output is 20 volts. Im stumped

Hello, I want to build this PWM flyback driver, but I have a few questions about it. Instead of using a 2N2222 can I swap it for a 2N3055, and instead of using one MOSFET can I use four connected in parallel.
