Hi, author here. I must say I'm not 100% confident in everything the STM32s do - and the rp2040/rp2350 is an easy one. One of my pieces of work is : continuous acquisition, acquisitions, processing, and writing on a fast storage,

As a way to go around this issue, I sense a bit of progress through compressed sensing, see for example http://advances.sciencemag.org/content/3/12/e1701423 . This would enable one (with enough horsepower) to

OP here -- I had played with a wireless probe and developed a very basic python framework around it, see https://github.com/kelu124/pyUProbe1 . Same origin: Shenzen. Very friendly contacts there, always a pleasure to c

Could be indeed! Augmented sensing, there's definitely something one can do. A ping (radar-like) every 5s, and in time you listen to echoes. The more intense, the higher the frequency. Ping me through the contact in the doc if you

One of the next experiment is to try with 8 small elements ;)

The point being that on these experiments, the sensor isn't an array of piezos, rather a single-element piezo. Cuts the costs (a fab invoices around 100-200e for such a sensor), but lowers the overall image quality.

Before trolling a bit, I remember the main costs don't come from hardware (though it definitely costs something) - rather for r&d, patents, and most of all proper certification, since, in the end, it's a matter of life and dea

Hey! Theres a link for tindie in the doc. It's quote expensive, high voltage being the main reason, but I'm planning on reducing the costs and have a cheaper on-board extension for the pi once this hardware stabilizes
