  • I do OK with faster-whisper for transcribing, and I built a wyoming container for pocket-tts that does pretty good local TTS but I am running it as a docker on a ryzen machine (no gpu) so YMMV. Pocket-TTS seems better than Piper IMO, it’s certainly faster for local TTS if all you’re using is CPU.

    I’ve been looking for a MCU that has enough oomph to do some noise cancellation onboard and I ordered up a couple of these in the hopes that the onboard NPU would be useful for that. It also has a speaker output and onboard mic. Price was right for 8GB of EMMC and 256MB of ram.

    It is much more accurate if you use the pump. I tried just measuring the pressure in the tube from the water column, it was all over the board and the resolution sucked, probably 10X worse. Using the pump fixes that because you aren’t just measuring how much the water compresses the air, you’re measuring exactly what pressure it takes to push out the bottom, which is exactly the water column.

    If you want an accurate measurement, you can put a tube that exits below the lowest water level you expect. Put a pressure sensor like an MPX2102 and an aquarium pump on the tube. When you turn on the pump and it starts bubbling out the tube at the bottom, the pressure you measure on the sensor will be relative to the height of the water column above the tube opening. 1"wc is approximately 249.082 pascals or 0.0361263 psi
