I am thinking about building my own portable starting platform and am wondering if anyone has tried this or could give some advice. The ingredients would be:

- small ladder (black in sketch)

- wooden plank (brown in sketch)

- pontoon / floater (green in sketch)

The pontoon would need to be sized large enough to keep it somewhat level while running along the plank. The plank would need to be attached to the ladder via a rotary joint to balance out small waves.

My biggest worries are the stability of the ladder (preventing it from tipping when jumping).

For context: Area of application would be in small lakes (no waves, calm water). I am a total beginner.

Thanks!

Sharing my long term project to bring transformer-based automatic speech recognition to a microcontroller. It is currently limited to english speech and can process max ~8 seconds of audio at once. I still think it can be useful for other projects that need voice recognition. The code and model are available on github .

Some specs for those who are interested:

• 13.1M parameter conformer quantized and distilled from nvidias "stt_en_conformer_ctc_small" model
• requires 256kb of SRAM and 4mb of PSRAM to run
• the model file is ~14mb, so it fits into the flash of the XIAO S3 plus
• uses vector instructions and miltiprocessing to accelerate model execution
• draws about 350mW while transcribing audio
• audio is recorded from the connected I2S microphone. I had to stack up some filter capacitors as the internal 3.3V regulator wasn't keeping the microphone supply voltage stable enough when the CPU is hit with intensive calculations.
