warning: date() [function.date]: It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected 'America/Los_Angeles' for 'PDT/-7.0/DST' instead in /usr/local/www/data/drupal57.desinc.net/modules/node/node.module on line 1885.

AVR Tiny13 Voltmeter/Ammeter

I'm currently enrolled in a materials fabrication course where our final project is to build an enclosure for a power supply. The schematic and design of the power supply are provided by the instructor. These things use big stupid 0-15v analog gauges. I thought I could design a better interface using a microcontroller and an HD44780 LCD, so here it is. Special thanks to Micah Carrick for the lcd library and Cory Meyer for general advice. The most difficult part of this project was squeezing it all into the 1024 bytes available on the tiny13 microcontroller.
