IoT Projects
PeggyBoard: An Interactive Climbing Wall
The PeggyBoard is “a Raspberry Pi project developed to be paired with your home “woody”/climbing wall. It features an easy-to-use web app that anyone on your network can open up and begin setting a custom route that will then light up the respective holds on your wall. These routes can also be saved so they can be revisited later.” – GitHub
A Loud Phone Ringer for the Elderly
Giovanni Aggiustatutto built a custom base for an elderly friend. The cordless landline phone’s base contains a loud ringer and flashing lights to alert the friend of an incoming call. – HackADay
Using Meshtastic and OwnTracks to Kick A Google Location Habit
Jonathan Bennet was searching for an alternative way to share location data with their wife and business travel. They combine Meshtastic, a LoRa-based mesh network, and OwnTracks, a GPS location tracker, to create a private (self-hosted) location-sharing service. – HackADay
HydroCleaner: River Cleaning Robot
A low-cost, ML-powered, robot that attempts to capture trash in small waterways. – HackADay.io
Screen Time Monitoring with Adafruit IO

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.
