Convergence proof... just for the fun of it (you give me the epsilon, I'll give you the N). Let me know if I've made any mistakes.

Weekend project: Raspberry pi 3d camera. I've mounted an Arducam time of flight camera on a usb stereo camera. Hoping to collect some stereo pair/disparity data for machine learning training.

Servo mount adapter for my robot head.

This is my latest. I've made a robot head with a raspberry pi inside. youtu.be/1slqTqzwvw4?si…

pcb design for esp32 shield to control 4 motors using Cytron 10A motor controllers. Inputs for dual quadrature motor encoders and outputs for pwm speed control and direction. Should i add a silkscreen picture before i send it to PCBWay

The Raspberry Pi is dead. Long live the Raspberry Pi.

New PCBs arrived today. For connecting four cytron md10c motor drivers along with 8 interrupts (2 per motor). Thanks PCBWay_Daisy & PCBWay -Elaine Hu.

Portable power solution for raspberry pi 5. I also tried a power bank which worked with throttling of cpu, and a buck converter, which didn't work at all. This is a 5V, 5A converter. I got it from Amazon amazon.com.au/dp/B0D5V5YDC3, but shop around.

Stereo camera for measuring distance of hand away with cvzone hand detector. We get the feature matching by taking corresponding points on the hand between left an right image. The rest is just simple geometry.

Mobile robotics platform which is inspired by the Stanford Mobile Aloha platform. The cost of this is around 1800 USD (frame & motors 800, arms 500, electronics 500). youtu.be/9S9H8HX5MNA

PCBWay I've got it working now with internet radio. Next I will put some code on it to take a photo and use text to speech to describe the scene.

The project connects an esp32 cam to an LLM, which takes as input the prompt "describe this picture?" together with the image, and then returns a description of the image. youtu.be/hMA0HNYTjm0

OMG - this is so exciting! We're live on Crowd Supply! Things just got very real :) crowdsupply.com/cmg-research/e…

Why did the computer scientist get Halloween confused with Christmas? Because OCT31 = DEC25

Happy new year everyone. May 2025 bring you peace and happiness. Fill your hearts with love.
