[chbot] Robotics Group meeting, Monday 21 Jan 2019, 1830, 5 Idris Road

[Trevor Wignall]

The very small USB microSD card reader that I passed around tonight is
Jaycar part number XC4740, which was $5.60. I thought that was a very
reasonable price for the functionality and size, and it includes a cap that
covers both the USB socket and the microSD card.
