Server hosting Adafruit style
Adafruit took pity on us and shared some valuable web hosting experience: After hearing about Dangerous Prototype’s search&move to a new hosting provider, we thought we’d post up about our hosting experiences! We currently use ServInt for our hosting provider. They’re what we would classify as a ‘full service’ provider. Basically they own the computer, […]

It’s intended for hikers, climbers, and other outdoorsy folks who want to know if it was colder last night than […]
Another OverLoad review
Another review of ITead’s OverLoad programmable dummy load: All in all, interesting device. The only major flaw I see attm is that instead of using DAC and drive the current value trough mcu they are doing that analogue … I’ll check schematic to see if there is DAC on board at all, but if not […]

App note: Overvoltage protection for amplifier outputs
rsdio writes: this circuit includes one of my favorites: a dual, common-cathode diode package To protect audio amplifiers and other automotive electronic circuits in the event of an accidental direct connection to the car battery voltage, add the circuitry shown (a shunt regulator, diodes, and an n-channel MOSFET in series with each audio path).
