If you’re a techie, interested in #hardware and #software systems you should know that an unnamed person has developed a chip that runs #python - natively. Python on hardware; no C, no VM, just a pure hardware implementation. And it’s 30x to 50x faster than alternative, non-hardware approaches. Use cases include #ML and #IoT and #sensors

Quantum Navigation via Magnetic fields.

<quote>
Even when the equipment was mounted inside a plane, where interference is much worse, it outperformed existing systems by at least 11x. This is the first time quantum technology has been shown to outperform existing tech in a real-world commercial or military application, a milestone referred to as achieving “quantum advantage."

Just ordered some parts to prototype a piezoelectric an experimental tactile interface for "feeling" visual textures.

I ordered a piezoelectric actuator, some through hole op-amps to drive it, a breadboard, some prototyping wire, some 1/8" prototyping jacks, an assortment of through hole resistors, and a big box of small plastic drawers to organize my parts.

I'm gonna drive the piezoelectric actuator by driving the op-amp with the audio out from my sound card on my PC. I'm planning to prototype a tiny MCU and tiny camera separately.

I'm so excited for this project.

I'm dipping my toes in #esphome reading the documentation, and it's awesome! It supports an huge quantity of #sensors, the data read from the sensor can be filtered and manipulated, it supports a lot of #displays and #graphic libraries! It is extremely well integrated with #homeassistant as it's the main use case. It's very flexible! I can see how I could do other little projects with this, but unfortunately it seems not to expose a standard REST Api...
They say the native API "is based on a custom TCP protocol using protocol buffers. You can find the protocol data structure definitions here: api.proto A Python library that implements this protocol is aioesphomeapi.", so I should be able to interface with it, but it isn't very interoperable (and it probably isn't meant to be)...

*edited to add: sorry I see it as base 1 now!

@kvistgaard @tanishqkumar

Gosh thank you for telling me about this. If I understand correctly, it's base-0? Are there any articles for lay-readers on it? I regret those I found either explained it as something I'd interpret as base-0, and I found hard to understand how to create and compute abstractions from that foundation, or they seemed aimed at readers who were already thinking in terms of computing with those abstractions, and I was a bit lost!

My applications for fast computing would be things like Wide Area Motion Imaging or gimbaled sensors that have to make tiny movements with superb accuracy and speed in order to see things very very far away.
