Browsing: Super Laser Show Geeking

Kyongsu and I stayed up most of the night geeking laser show stuff, these pics are of the new and extra-improved DAC (Digital to Analogue Converter) board, which lets the computer talk to the laser scanner amplifier.

Our project, codename: Ghettolaze

oooh, artsy shiny solder points!

Kyongsu solders some parts onto another board

278 degrees celcius ... my favorite soldering temperature

Tonight, California ... tomorrow ... the hospital, getting treated for severe electric shock ... ha ha just kidding ... no geeks were harmed in the making of this DAC board.

The completed board, chip sockets, capacitors and reistor banks soldered on

Testing the board with the aid of the schematic diagram

Installing the ICs into the board

The finished DAC board! Those pins on the left connect it to the parallel port

a simple grid scan test, before we tuned the amp (and before we turned on blanking support in the software)
