MOSFET blow-out
As in low prices, not release-the-smoke. Browsing for parts for a project on the Mouser site and I ran across this mosfet (20V, 2.5A, very low turn-on voltage). Looks like Mouser...

IO via USB - how simple?
I want to add some custom IO to a PC and USB seems the natural route. Total IO would be on the order of 10-20 bytes worth. I know almost nothing about USB. I do know what's...

USB - RS485 converters?
I have a general question about USB-RS485 converters. Most of them (e.g. search "USB RS485" on ebay) have a connection for +5V or +9V. In your experience, do these devices...
