Spent most of last night trying to fit 110KB of MicroPython along side 200KB of Ember Zigbee stack inside the 256KB flash of the EFR32 used in Ikea's Tradfri smart home devices. That's a bit of a squeeze, even before trying to fit the extra 3KB of data in the 32KB of SRAM.

@welshpixie after filing the PCB notches these two pieces fit together, although that's far too much effort for the entire dodecahedron. Next version will solder together instead.

The first version of my small stellated dodecahedron puzzle is a challenge to assemble, especially since the PCB tabs aren't the right size to interlock. The radially symmetric silkscreen art work by @welshpixie looks wonderful!

Progress decoding the header format, although the CRC algorithm is still a mystery.

Reflashing the CC2531 ZigBee coordinator firmware requires a finicky connection to an Arduino.

This is that odd week where the US is an odd hour off from EU timezones. Best to avoid scheduling any transatlantic conference calls.
