While I wait for launch, I designed a quad WaveBird receiver, the FlippyBird. Installs internally with auto wired controller passthrough, can be used standalone via USB, solderless, config-via-controller so you never see it. Should be cost competitive vs a single oem receiver

Looking like you can keep your disk drive with flippydrive too! So far the new flex, pico spring contacts, and bypass mode work, so solderless byoPico drive+ode is happening. I needed to bodge two wires but the rev3 boards are good enough for development. 4th time's the charm?

@KingDemic @Rainmaker1973 If I had to take a wild guess, I'd say dispersion. Different frequencies of sound travel at slightly different speeds, so the component frequencies of a big impulse like a thump will spread out as they travel through the confined space, with the higher frequencies arriving first

A few have asked about the self-install pico process. It's not bad. Countersunk screws cause the board to align on the contacts, so it's as simple as place and screw down. Only gripe is the screws are small. Like all RPi products, the pico has some *interesting* mounting holes

It's fixed!!!! The solder joint on this resistor failed after 20 years of vibrating (and me hitting endstops with my bad commands). It sets the write current, which is why writes were disappearing. If you see a 64DD that can't write but is error-free, this is the thing to check!
