MuHack SAO 10th anniversary
For the 10th anniversary of the MuHack hackerspace, I made a little SAO that can also be pinned to your shirt or backpack, working off a button battery.
Features
- Two configurations: SAO and pin
- Two LEDs mounted on a transparent part of the PCB
- I²C interface for connecting a small SPI flash memory
- Gold-plated for a neat design
- Clasp butterfly pin
Getting Started
This PCB is designed to be used in two different configurations: as a pin or as a SAO.
The pin configuration is the simplest, with only two LEDs and a switch to turn them on and off, everything powered by a CR1220 battery.
There is also a solderable footprint for a clasp butterfly pin, so you can wear it on your shirt or backpack.
BOM for PIN configuration
- 2 × 0805 LEDs
- 1 × CR1220 battery holder (e.g. Keystone 3002)
- 1 × CR1220 battery
- 1 × 0805 1 kΩ resistor
- 1 × switch for on/off (e.g. C&K PCM12SMTR)
BOM for SAO configuration
- 2 × 0805 10 kΩ resistors
- 1 × SPI SOIC-8 flash memory (e.g. Winbond W25Q32JVSSIM)
- (Optional) Everything listed in the PIN configuration BOM except the battery and holder
- Do not use the SAO configuration with the battery inserted, as it may damage the circuit or the connected badge!
