The vcNOIZ DIY project was available as a full kit which includes the PCBs with the SMD components pre-soldered and the 6HP eurorack panel.
The ACXsynth MIDI2CV project was available as a DIY kit exclusively. Thanks to Alain Coupel for granting us permission to use his fantastic circuit ideas here! A huge, heartfelt thanks goes out to Dmitry of Modularsynth.ru for his work on the V5 firmware updates. If you like his work, you can donate to him at his link below. Also, you can find the firmware files for his version for download there.
The Jupiter Storm DIY project was available as a PCB + panel set. It is, however, an advanced project compared to some others, and you will need to make your own panel bracket and have a fairly deep case to accommodate the large circuit board.
