reading, I have found that a flip flop is a much more complex device ...

Digital dimmer: Triac vs MOSFET in a circuit?
I want to dim a 120Volt-60Watt light with a digital controller.
I already have a circuit that use a Triac but I would prefer to use a
power MOSFET.

I've got a gigabyte motherboard (GA-7BAXP) that has suffered a blow out due

I recall some years back there was discussion on how to actually burn
readable text, patterns or such onto the surface of a CD-R using a
