			We do have more unassembled hardware kits. However, first we need to complete our current LCA2022 delivery commitment to those who have already registered. After we've completed delivery for LCA2022, we'll review our stock and options then.

			All the individual SwagBadge components are tested ... only a final complete device test to do for each one (just to be sure). The minimal viable firmware needs to (1) enabled Wi-Fi configuration for your network and (2) support Over-The-Air (OTA) firmware upgrade ... both of which exist from OHMC2021. A new TFT LCD screen driver (providing backward compatibility with the SwagBadge2021) needs to be completed ... and not exceed the memory size available to microPython.

	The Rockling FPGA Bootloader is a variant of Foboot, which configured and tested for the Rockling differences. That is all we need to flash on the device before shipping and is ready to go. AndyK has had to develop Gatewate and Firmware that acts as drivers and control software for the Rockling hardware, e.g FPGA, Theremin Analogue Front End input (AFE), I2C DAC, I2C Audio Codec output (SGTL-5000) and host-side support. The final piece to complete before shipping are the I2C commands for the Audio Codec, which has turned out to be more complex than original anticipated.

	As discussed during the conference, the problem on the Rockling with high current draw and 50% yield with the boards was because Jon didn't realise the oscillators were polarised, and he installed them in random orientation! Now that we've tracked that problem down and reworked the oscillators on the failed boards, almost all the Rocklings have passed our initial testing.

	These modifications need to be done in a way that still allows the other parts to be installed on the board. Jon's son Tom has been working on these boards. They should be complete by the end of this coming weekend.		These modifications need to be done in a way that still allows the other parts to be installed on the board.
