David Johnson-Davies published another great and detailed tutorial on how to build an IR remote control detective. He writes: The IR Remote Control Detective decodes the signal from several common types of infrared remote control, such as audio, TV, and hobbyist remote controls. To use...

David Johnson-Davies published another great and detailed project based on ATtiny85. It's an harmonic function generator with an OLED display. This article describes a simple function generator based on an ATtiny85 which allows you to generate a virtually unlimited number of waveforms...

An SD card based standalone AVR Programmer is live on kickstarter and has 24 days to go. Here at proto-pic HQ we make kits, lots of kits, and that means lots of AVR programming. We found this a tedious task and wanted a solution to make the whole thing quick and easy. No more did we...

David Johnson-Davies published another great tutorial on how to use the Tiny Graphics Library to plot the outside temperature over 24 hours on a 128x64 OLED display using an ATtiny85. This small graphics library provides point, line, and character plotting commands for use with an I2C...

This is a complete GSM/3G mobile phone, based on the ioNode. Features 128 x 64 OLED display * 16 buttons + 5-way mini-joystick * Microphone & earpiece * MicroSD card slot * MicroSIM card slot * MP3 decoder, headphone amplifier and 3.5mm stereo jack * Vibrator Trill - an...

Here's a tiny pcb that produces an annoying sound using a piezo buzzer and a ATtiny13 microcontroller. It uses an LED, piezo buzzer, ATTINY13 Atmel microcontroller, a very small amount of Arduino code, and a coin cell battery that should last about a week. Battery life could be...

The new STM32WB from STMicroelectronics is a new wireless supporting System on a chip (SoC) that comes with a fully-featured ARM Cortex-M4 (@ 64 MHz) based microcontroller to run the main computing processes. It also has an ARM Cortex-M0+ core (@ 32 MHz) to offload the main processor and...

David Johnson-Davies build a tiny function generator based on ATtiny85 microcontroller. He writes: This article describes a simple function generator based on an ATtiny85. It can generate triangle, sawtooth, square, and rectangular waves, a pulse train, and noise. The frequency can be...
