Bubble Punk

Mohit Bhoite made Bubble Punk, a nifty little sculpture to measure temperature and humidity.

Along with a Teensy-LC, the sculpture uses an Adafruit SHT32-D sensor breakout board, a vintage HP5052 7415 7 segment display, and a WS2812B LED to light it up.


Dean Blackketter’s Expansion Add-On for Teensy 4.0

Dean Blackketter created an add-on board which makes Teensy 4.0’s bottom-side pads available as a second row of normal pins!

It attaches underneath with castellated holes to solder to Teensy 4.0’s bottom-side pads.

If you’ve wanted a way to plug Teensy 4.0 into a sturdy through-hole socket and have access to all the signals, this looks like a really nice way to gain easy access to those bottom-side pads.

Dean shared this PCB on OSH Park and the Kicad files on Github.¬† Much more detail is available on Dean’s forum post and conversation which follows.
