Mini DDS Synthesiser updated! A "poor-mans" DDS (Direct Digital Synthesis) circuit. This one uses an AVR 2313 and a simple R2R resistor ladder network to generate frequencies from about 0.07 Hz to 200-300 kHz in 0.07 Hz steps.

Temperature Controller A temperature monitor/controller based on an AVR 2313 and a Dallas DS 1621.

Monster memory How to interface a DRAM to a 8515 and get a 512kB (or more) linear address space.
