My students @eshapatel.bsky.social & @jennywbe.bsky.social use break beam sensors for their #CircuitPython #NeoPixel Hop Scotch. Major prototype milestone complete. So proud of your work & can’t wait to see the final product!

#Caturday Contraption. Testing build for the RaspberryPi Pico CircuitPython rubber band launcher before I create a tutorial. Unclear if Admiral Grace is enjoying this or just humoring me. #CircuitPython #RaspberryPi #Pico

Week 11 of Boston College Physical Computing. Students built joystick controlled rubber band launchers. 3 servos, a joystick, button, a 3D printed model & laser cut base. We learned about recognizing ways to improve user experience & code for improved control & positioning.

A scene from tonight’s exam when students had to turn a potentiometer to get one of the Sesame Street martians to say “Yip, Yip” faster. Not shown - they also had to get a servo to pop up the head as the speed increases. I continue to write exams to amuse myself.

Got some thin square pipe to work in pebble style ws2812 neopixel LEDs. Diffusion looks good. Will experiment with some volumetric animations after creating a filled cube of these but first lots of work for classes to complete.

Some experiments with 240 NeoPixel LEDs in 9 concentric circles, running on PixelBlaze. Video never captures the complete coolness. Will add this to student display area for more inspiration. These are the LEDs I used: www.aliexpress.us/item/3256806...

Problem seemingly solved. I needed BOTH a common ground from the Pico 2W to the minus (-) in at the display powering barrel jack AND I eliminated interference by replacing 8" pin-socket wires from pico to display with 3" pin-pin wires that then went to the HUB75 ribbon cable.

CircuitPython, MicroPython & raspberry pi pico friends. Some of my students are using HUB75 displays with pico 2Ws and are getting results like this. They are powered by a 5v10a power supply. The pico is separately powered via USB. Suggestions?
