An Adapter to Solve Your ESP-01 Breadboard Woes

The ESP-01 launched the ESP8266 revolution back in 2014, and while today you’re far more likely to see somebody use a later version of the chip in a Wemos or NodeMCU development board, there are still tasks the original chip is well suited for. Unfortunately, they can be tricky to …read more

Google’s Pigweed for ARM development is a nice surprise

Setting up an environment for Embedded Development was traditionally a pain and so vendors provide integrated development environments to help bridge the gap. Google has open-sourced their version of an embedded targeted environment designated as embedded-targeted libraries which they trademarked Pigweed.

Google trademarked Pigweed with the U.S. Patent and Trademark …read more

Hearing Plants Giggle Is Just As Creepy As You Think

While best known for Charlie and the Chocolate Factory, Roald Dahl wrote quite a few similarly oddball stories in his time. One of them, The Sound Machine, is about a device that allowed the user to hear the anguished screams of trees as they were cut down. Sounds …read more

Open-Source ARM Development Simplified

The ARM series of processors are an industry standard of sorts for a vast array of applications. Virtually anything requiring good power or heat management, or any embedded system which needs more computing power than an 8-bit microcontroller is a place where an ARM is likely found. While they do …read more

Scott Shawcroft Is Programming Game Boys With CircuitPython

Some people like to do things the hard way. Maybe they drive a manual transmission, or they bust out the wire wrap tool instead of a soldering iron, or they code in assembly to stay close to the machine. Doing things the hard way certainly has its merits, and we …read more
