I recycled an old Pi, broken keyboard and display to make retro-ish computer that boots into BASIC. Saved me a fortune on buying a DevTerm.
How are they going to top this with the real OTTO?
The "instructional video" is a flipbook!!!

Uses the Microchip MCP3424 ADC. Various build options are possible, including single-ended and/or double-ended inputs to the ADC, separate analogue voltage supply (via DC-DC converter and linear regulator). Two open-drain outputs enable switching of fans, relays etc. There are connectors for the buffered I2C interface and a 1-wire interface.
I have several intended uses for these PCBs, including a Raspberry Pi magnetometer and a temperature sensor/fan controller board for an auroral camera.
