  1. Because I like the concept, here's this years #GoodOf2024. A concise list of projects I did in 2024, to actually convince my brain that yes, I actually achieved something.

    - Helped @patagona with his ISDT #CM1620 reverse engineering
    - Built the #Framework #DongleHiderPlus expansion card
    - Implemented MQTT data logging for the #ePocketBike stats
    - Started development of an #Arduino compatible Ethernet stack for the cheap #CH32V208 MCUs (built-in 10M PHY)

  2. I've recently discovered the ISDT CM1620 charging modules.

    They're pretty cheap (~140€) and promise some pretty good specs:
    - ~11-70V / 1100W input
    - ~8-70V 20A / 1000W output
    - LiHv, LiPo, LiFe 2-16S balance charging
    - Control via Micro-USB, Bluetooth, RS485, CAN or an optional controller with display

    From our tests, they work fine, even at max load (16S 15A).

    However, they do have some quirks...
