Strange problem with 220V boost converter
Hey George, I think you mistook svofski for the thread opener. But still, thanks for that explanation.

Strange problem with 220V boost converter
Max current, RDs[ON] and The curve which shows max Ids at particular gate voltages. Usually you would want to drive the gate with at a lot more voltage than the Threshold is rated...

Transistor Questions - Driving LED Arrays from GPIO
Quickly switching (High frequency PWM) mosfets could be tricky if you are driving them directly from GPIO pin. Since they work on voltage any stray capacitance on the gate will...

Transistor Questions - Driving LED Arrays from GPIO
A ULN200x type of transistor array would be ideal here, but i guess you want to do it with those tip41 that you have available. Anyways, as stated before, you should look at the...

circuit simulation graphics
Proteus has a feature which draws arrows on the wires in the direction the current flows. It also colors the wires based on the voltage.

A simple question: Why doesn't this get optimized to SBI/CLI
It's an Attiny2313. And thanks for clarifying.

[TUT] [HARD] [SOFT] [C] USB tutorial with V-USB & ATtiny
I'm glad someone is doing V-USB tutorial. I was too lazy to figure it out by my self. Waiting for the critical 3rd part : )

Reverse Current Protetion
You could use a P-CH mosfet.

Cascading AS1109 led drivers with one current set resistor ?
Thanks peret, I think I'll do that.

Cascading AS1109 led drivers with one current set resistor ?
That's what I thought, so a small resistor for each chip and one common potentiometer would do the trick ?
