Hi all, I've recently finished building a nice high quality amplifier based on National's LM3886T IC. It has some cool features like audio grade caps, solid copper bus bars between power caps, active tone control, a copper plated case, custom made and painted PCBs, etc so forth.
Anyway.......
it also features a picaxe that drives the 24x2 red LCD, that displays capacitor voltage, current averaging through the amplifier, and chip heatsink temperature (DS18B20). As a novelty, it has a DS1307 RTC that recorded the start point of the amplifier's life, and when you switch it on, it displays in years/months/days/hours/mins how long it's been since it was 'created'. It also displays Happy Birthday messages according to the date and family birthdates....
