A couple years ago I did a workshop for CodeMash on building a portable gaming system based on the Teensy 4.1. This is an incredibly powerful microcontroller development board created by Paul Stoffregen over at PJRC. It’s powered by an NXP i.MX RT1062 crossover MCU with ARM Cortext-M7 running at 600 MHz. Despite its cutesy […]
Want to build a versatile and hackable ESP32-based controller system with lots of useful peripherals and a full assortment of apps to get you started? Then the ESP32 R4ge Pro is for you!
Meet the next generation prototype of the ESP32 Conference Badge, featuring high-fidelity sound and an expanded array of useful peripherals.
A waveform generator is a handy little tool for stimulating and testing electronic components and assemblies. Any work with filters, amplifiers, or other frequency-sensitive designs can benefit from the insights gained through a controlled signal input. Here’s how to make one for about $30.
The Atmel ATtiny85 is capable little 8-bit microcontroller that plays very well with the Arduino ecosystem. It also comes in a compact and maker-friendly 8-pin Dual Inline Package (DIP), operates on 5V, and costs less than two dollars – making it a great option for controlling some WS2812b RGB LEDs (aka “neopixels”.)
