First steps

A project log for Overly complicated laboratory power supply

Average power supply, driven by a rotary dial, lot of TTL ICs, metal can transistors and vintage components

This project started a few weeks ago, in fact. I took rotary dial and partially breadboarded the dialing circuit.

No big deal, just a little bit of sequential logic and contact debouncing. The dialing circuit alone contains 14 ICs and it will grow up more. Stay tuned for more TTL ICs and detailed circuit descriptions.
