• I'm a bit short on time lately, but I got to tinker a bit on the Mk4 prototype. It is painted for improved water resistance but I don't like that a lot since it seems and feels cheap. Final one will probably have a metal underside and some sort of waterproof plastic for the top.
    The last build was extremely fiddely because I had to solder on both sides of the board. So this time I have decided to move all soldering to the top side by using copper and polyimide tape as makeshift traces to wrap around the border. This will hopefully keep the internal cabling shorter at the cost of having to solder if disassembly is needed.
    The "antenna" is also just a bit of copper tape to test out if a completely random antenna will work at least a bit in preparation to maybe using a full metal case as antenna.
    Mk3 developed a bit of a flaky BT connection, probably caused by moisture ingress since the nylon SLS is porous. I will check that when the new one is ready, whenever that may be ;)
