[LAU] [OT] Open Source Portable Recorder?

[Johannes Kroll]

Hi all!

This is kind of off-topic here but I thought if there is such a thing,
some of you guys might know.

I'm looking for an audio recorder where the firmware and/or the
hardware is hackable. Ideally, this would be similar to the Tascam
DR-05 in price and features, but with free/libre firmware and hardware.
Maybe someone knows of such a project?

Alternatively, is any of the "closed" devices such as the Tascam DR-XX
known to have modifiable firmware?

Thanks for any pointers!
Johannes
