IoT Projects

Listen to Wi-Fi data, just like the dial-up days!

AOL recently disconnected their dial-up service. Nick Bild said he “felt sad” about the “end of an era”. He built a project to capture Wi-Fi data and convert it to audible signals. While dial-up was sending analog signals (audio), this project mimics this by modulating the digital Wi-Fi packets into audible noises and plays it back through a speaker. The link past the break has a great write-up about how Nick got this fun project working. - HackaDay

Mini UPS for your Wi-Fi Router

A simple UPS (uninterruptible power supply) built out of low-cost parts to keep a WiFi router online during a short power outage or spike. - HackaDay.io

Rugged LoRa Repeater for Off-Grid Communications

While increasing the LoRa (Long Range) radio communication output’s power is illegal, Bertrand Selva developed a repeater to broadcast signals over extremely long distances. The repeater is “ultra-discreet”, uses low-cost materials (D batteries, standard PVD pipe fittings), and can run over five years in an off-grid location. - HackaDay.io

My fan worked fine, so I gave it WiFi

Ellis Clayton designed a fully reversible modification for a Vornado 633DC fan to control it remotely over WiFi. The final result is concealed entirely within the fan’s housing, leaving no visible modification. - Adafruit Blog

Pool Party Notifier

Build an internet-connected pool notifier to alert the neighborhood that your pool party is underway! When your pool is ready for guests, press a button on a web dashboard to send the flag up. We’ve also designed a 3D-printed enclosure to house the project. - Adafruit Learning System

ESP-NOW LED Juggling Balls

Interactive, wireless musical LED juggling balls using the low latency ESP-NOW protocol. The juggling balls can wirelessly trigger MIDI notes based on catch detection with an accelerometer, and bridge messages to your computer or USB Host synthesizer. - Adafruit Learning System

Nest Gen1/Gen2 Get a New Lease on Life

Breathing new life into bricked and outdated Nest Generation 1 & 2 thermostats, this project replaces the proprietary Google firmware with open-source firmware, allowing users to regain control over their devices. This firmware is also completely decoupled from Google’s servers and services. - GitHub

No more ZigBee hubs for IKEA smart homes! IKEA is finally launching 21 new smart home products — all built to work with the Matter standard. - IKEA

Raspberry Pi Unveils the $18 Compute Module RP3

Low-cost castellated “stamp” style module borrows the RP3 from the Raspberry Pi Zero 2 W and puts it in a new form factor for Chinese customers. - Hackster

Support Adafruit

Here at Adafruit, we sell all of these amazing components, but we couldn’t find a good way to interact with them over the Internet. So, we decided to create our own IoT platform, and that’s Adafruit IO. It’s built from the ground up to be easy to use and platform agnostic (connect any development board or device!). For those who want to get a project off the ground without programming - Adafruit IO offers a No-Code interface for building IoT electronics projects using WipperSnapper, our open-source IoT firmware. Support Adafruit’s open-source development by subscribing to Adafruit IO Plus, the upgraded, all-systems-go version of the Adafruit IO service.
