David Johnson-Davies published another tiny project. This is an ATtiny85-based digital music box that will play a tune stored in memory in MIDI format: The notes sound like a music box or harpsichord, with a decaying envelope, and there are four channels, so up to four notes can play...

This is a Tiny Serial Terminal based on ATtiny85 and 256x64 OLED SH1122 display able to show 42 characters per line. David Johnson-Davies writes: This article describes a text display based on a 256x64 OLED display that provides 8 lines of 42 characters per line. Its width makes it...

The nRF52840 Micro Dev Kit USB Dongle is a small and low-cost development platform enabled by the nRF52840 multi-protocol SoC in a convenient USB dongle form factor. The nRF52840 Micro Dev Kit USB Dongle features a programmable user button, RGB LED, up to 12 GPIOs and 2.4G Chip antenna...

Outstanding audio, voice and video processing The i.MX 8M family of applications processors based on Arm® Cortex®-A53 and Cortex-M4 cores provide industry-leading audio, voice and video processing for applications that scale from consumer home audio to industrial building automation...

Using a Raspberry Pi to program an ATTiny4/5/9/10. But, mostly the $0.25 ATTiny10. And, not necessarily a Raspberry Pi, but anything with GPIOs! Yep. It works. At least tested pretty thoroughly with my ATTiny10. It can also read all the memories AND run timings against the AVR to do...

STMicroelectronics has introduced two STM8* Nucleo development boards, letting the 8-bit world experience the ease of access and extensibility already proven with the STM32* Nucleo range. Leveraging the formula that has kickstarted countless STM32 embedded projects, the STM8 Nucleo...

David Johnson-Davies build a OLED display function plotter based on ATtiny85 microcontroller. He writes: This project describes a simple routine for plotting a function on a 128x64 I2C OLED graphics display. Unlike most Arduino graphics libraries this routine doesn't require a RAM...

A 1" by 1" 20msps Oscilloscope based on the PIC32MZ @ hackaday.io by "Mark Omo". He writes: This project is designed around a PIC32MZ EF processor. We use its internal ADCs in an interleaved mode in order to get the full 20Msps. We have found that in practice we are able to achieve...
