Last week on the Adafruit Learning System, we published 3 guides. This week we have a new skills guide, an amazing new weather station guide, and a new product guide! As a bonus, I totally forgot to mention the new product guide we published last week.

Favorite New Guide

This week my favorite new guide was made by the Ruiz Brothers and Brent Rubell

Build a 3D printed enclosure for your IOT Air Quality Sensor. This project is similar to our other air quality sensor guide, except it uses Adafruit STEMMA sensors and has minimal soldering required.

This project uses sensors to measure PM2.5 (particles that are 2.5 microns or smaller in diameter) dust concentrations, temperature and humidity.

This weatherproof enclosure is modeled after a silo-home. We’ve included different types of mounting holes and brackets for different mounting configurations.

ALS Deep Cut

The Adafruit Learning System has now 2,335 published guides! As you can imagine, some amazing guides of years past get buried and lost. ALS Deep Cuts brings these guides back up to the surface.

This weeks ALS Deep Cut was published all the way back in 2012. Once again, our oldest deep cut yet! Phillip Burgess shows us how to paint with LED lights using a Raspberry Pi.

Light painting is an artistic photographic technique combining long exposure times with lights in motion. Traditionally these images have been hand-painted with a penlight…but more recently, affordable microcontrollers and addressable RGB LEDs have brought a new high-tech twist to the idea.

New Product Guides

Like I said before, I forgot to include the new product guide last week, so this week we have two of them. The first is the Adafruit Voice Bonnet for the Raspberry Pi.

Your Raspberry Pi computer is like an electronic brain – and with the Adafruit Voice Bonnet you can give it a mouth and ears as well! Featuring two microphones and two 1 Watt speaker outputs using a high quality I2S codec, this Pi add-on will work with any Raspberry Pi with a 2×20 connector – from the Pi Zero up to the Pi 4 and beyond (basically all but the very first ones made).

The newest of the new product guides is an awesome new product… The Adafruit Metro ESP32-S2 board!

What’s Metro shaped and has an ESP32-S2 WiFi module? What has a STEMMA QT connector for I2C devices, and a Lipoly charger circuit? What’s finishing up testing and nearly ready for fabrication? That’s right – its the new Adafruit Metro ESP32-S2! With native USB and a load of PSRAM this board is perfect for use with CircuitPython or Arduino, to add low-cost WiFi while keeping shield-compatibility
