IoT Projects
3D-Printed Wind Gauge
Sebastian’s novel wind gauge design can determine both the direction and speed of wind. There’s no moving parts and the data produced feeds into his home smart home system. As a YouTube commenter put it, “it’s an analog joystick, but for wind”. – YouTube
WiFi Status Indicator Box
A visual alert to let you know when your WiFi network is down – HackADay
HITL – Continuous Integration for Hardware
(EDITORS NOTE: We’ve been looking for a way to test hardware automatically, this is a great project!) Deqing is developing an automatic method of testing hardware, complete with GitHub integration. On each GitHub push, firmware is automatically uploaded to physical hardware and tested. The results are published to the firmware repository’s GitHub Actions. – HackADay.io
Repurposing Old Burglar Alarms for a Modern Smart Home
Jeff Sandberg’s project brings a home alarm system from 1990 into the modern era. – HackADay.com
Post on BlueSky with a Raspberry Pi Pico W
The BlueSky social network has gained popularity in the past month. Les Pounder published a guide for using a Raspberry Pi Pico W about sending data from an inexpensive microcontroller development board to BlueSky. – Toms Hardware

Power-over-Skin: Full-Body Wearables
Carnegie Mellon University researchers are developing a transmitter to allow power to be transmitted over human skin at a frequency of 40 MHz. The supplied power is very low but could be used to develop new types of wearable devices – FigLab
MQTT turns 25 – here’s how it has endured
Andy Piper writes about the 25th anniversary of the MQTT specification, its history, and where it can go from here. – AndyPiper

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
