My goal: build an outdoor robot to keep the deer away from my plants. Learning goals: - Brushless motor control: has now reached cheap commodity status and would be good to learn more about. In the past I was always stuck between DC toy motors and full 6 wire AC motor control. - Vision system on a small micro with edge-AI model for deer detection. After decades of classic machine vision I think it's time to overcome…

This sounds like an amazing project and learning opportunity! Reminds me of a halfbaked hardware+software project idea of my own: - Goal: increase the amount of natural light in my apartment during the day - Mount a flat mirror on a motorized sun-tracking attachment on south-facing balcony railing - Set up geometry, software, and motor to rotate the mirror so that it always reflects a beam of sunlight into the apartm…

If you focus multiple mirrors on a single spot, you can set things on fire. Depending on one's application, this is a feature, not a bug!

There is a similar project for rabbit deterrence that might give some helpful ideas on the approach: https://blog.roboflow.com/rabbit-deterrence-system/

Awesome, thanks for the link! The vision portion is very much what I'm imagining for my deer deterrent.

After 2022, it's both hilarious and sad to see how blockchain type recommendations have fallen off so hard. What a gigantic waste of time and effort that field has been. I still have yet to see anything useful come out of it. NFTs always are pointed to as the "useful" thing, but tbh, if I'm buying art, I'd much rather have some well regarded painters work hung in my living room. Not some monkey as my twitter avatar.…

There are really good applications of blockchain, unfortunately most effort was focused on the dumbest ones.

Take for instance identity management - hospital ticketing system, where the patient's records are linked directly and inextricably to the tickets, etc. You can request an appointment using a smart contract, and everything else will happen magically.

Maybe someone worked on such systems, but they didn't get any airtime. I think eventually it will happen.

Here would be my guess: * GPU programming (GPUs have consistently kept up with Moore-like laws) * FPGA/ASIC design (hard but price for all of these is dropping rapidly, so becoming more accessible) * Bitcoin/cryptocurrency related tech, including standing up your own miner, full node, or understanding how to build applications on top of it (web3/etc.) (despite the hate, cryptocurrencies are still around and thriving)…

for GPU programming what area's would you suggest to start with? should i just dive into CUDA?

Triton is pretty hot right now you can check it out.
