DeskGuy is a small companion that sits on your desk. He is a cool air-quality monitoring buddy with feelings! When your room's air quality drops, due to high ‭CO2‬ levels, for example, he will start to feel unwell. The longer you wait to let some fresh air in, the worse he gets, until he eventually dies. He also measures the noise level, the light level and temperature. if it gets to loud (over 80db) he will start feeling stressed, if it is dark he will go to sleep. if its too hot he will sweat and if its too cold he will freeze.

Dum-E is a small Iron-Man-style 3-axis robotic arm with a gripper claw, driven by a Seeed XIAO ESP32-S3 running CircuitPython. I pose the arm live with four potentiometers (one per joint), hit Record, and it plays the motion back — teach-by-demonstration, just like Tony Stark's "Dum-E". It has a custom 2-layer KiCad PCB (XIAO ESP32-S3 + PCA9685 servo driver + dedicated 5–6 V servo power + pot/button headers) and a 3D-printed structure adapted from the open-source EEZYbotARM MK2. This is my second Hack Club hardware build after my Hackpad.

A custom 9-key mechanical macropad with a rotary encoder and OLED display, built around the Seeed XIAO RP2040. Every key is freely configurable through a desktop app, and the encoder browses through profiles shown on the OLED. PCB and case designed from scratch in KiCad and Tinkercad.
