It‘s still an active project tho. They updated the firmware to work with the new DISCO board screen. I just recently broke mine out to test recovery from cold storage, and it works great with Sparrow.

Bitboy by Justin moon led me to specter diy,
Specter founders showed me SeedSigner.
I always mention Specter DiY in my posts, but one thing that limits me from recommending it more is that you have to connect to a PC to install the firmware - which is why they pointed me to SeedSigner if my memory serves me correctly.
Tru you have to mount the internal storage as a drive to install the initial firmware.
