e-Ink Postcard Frame
This digital picture frame with an e-Ink display allows friends to upload and share photos to the display via a web interface. The project’s creator notes, “a kind of slow, fancy and black and white Snapchat”. – Hackaday.io
VR Spectrum Analyzer
A virtual reality interface for the spectrum analyzer software package, RTL-SDR. Considering most of our reader’s workbenches are full of diagnostic tools with small displays like oscilloscopes or multimeters, there’s a lot of potential in VR/AR tooling for engineering work. There’s a video on YouTube showing the tool in action. – GitHub.com
LoRa QWERTY Communicator
A “feature-packed” communication device for communicating text messages over the LoRa protocol. This project provides an alternative to cellular-based text message communication with low setup overhead. The editor especially likes the repurposing of a Blackberry Q10 keyboard. – GitHub
Plant Bot – Automated Plant Care
A “smart” gardening stake project that monitors and measures a plant’s moisture. Plants can be watered by pumps connected to the plant bot stake, too. – Hackaday.io
Building A Smarter Sprinkler System
Chris moved into a home and the “existing sprinkler system controller turns on when it is not supposed to and forgets everything whenever the power blips”. The completed project integrates into Chris’ existing home sprinkler system controller and he now manages the 24V system using Python. – cdake

S1 System On Module
Silicon Witchery announced their S1 “System on a Module” for Bluetooth, FPGA, and Battery Management. This “hybrid” module mixes 4 components which are traditionally separate on a development board, into one chip. The S1 contains a nRF52 for processing and Bluetooth 5.2 support, a flash module for boot-code and user storage, a iCE40 FPGA for additional GPIO/SPI/I2C peripherals, and a PMIC buck-boost for charging. – Silicon Witchery
ESP32uesday: ESP32 Family, GPIO and Adafruit_Protomatter
Adafruit’s Phil B writes about the journey to acquire a more profound knowledge of the Espressif ESP32 family. – Adafruit Blog
Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. Our standards page is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to. While Adafruit is not an independent journalistic institution, Adafruit strives to be a fair, informative, and positive voice within the community – check it out here: adafruit.com/editorialstandards
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.
