Hardware

This folder contains details of STRACHEY's hardware.

STRACHEY is implemented using through-hole components mounted on two PCBs, each measuring 88 * 108 mm.

The majority of the electronics, incuding the Arduino Nano, are mounted on the 'main board', whilst user-interface components are mounted on the 'control board'.

The boards are joined electrically by two 18-way 0.1 inch headers and an 8-way 0.1 inch header. I cut the 18-way headers down from 40-way headers (of which I keep a stock). There are holes for M3 bolts to secure the boards together for those taking the system "on the road" - people using the system in a static installation will find that the headers alone provide a secure mechanical interface. The component board is secured to the front panel by the sixteen "Thonkiconn" jack sockets and the three 9mm potentiometers.

The system was developed in KiCad (the first electronic project I have undertaken using this software). KiCad projects for the boards are presented in the Main and Control folders, along with schematics, BoMs and limited circuit descriptions. A Front Panel design is also available as a KiCad project.
