ATtiny13 – dance lights with FFT

This experimental project shows how to use ATtiny13 to synchronize live music and lights with only a few additional components required. Project uses single ADC (Analog to Digital Converter) channel for signal acquisition and some DSP (Digital Signal Processing) calculations that in real-time separate three frequency bands and make the LEDs dance in sync with the … Read more

Family of Minimalist Boards for AVR (MBAVR)

Sometimes it makes the most sense to design systems from the ground up, and other times when simplicity or a quick project completion is desired, pre-built system boards are a better choice. These four MBAVR development boards has been designed in order to create a minimalist and very useful environment to support a rapid development … Read more

[MBAVR-4] Minimalist development board for Atmega16/Atmega32

Yet another quick how-to guide of making a minimalist development board for AVR. The MBAVR-4 development board is designed for megaAVR MCUs like Atmega16 and Atmega32. It is a 4th and last project in series of MBAVR family home-made boards in order to create an nice environment for rapid development. I did these all things … Read more

This is another quick how-to guide of making a minimalist development board for AVR. This time is about MBAVR-3 development board designed for megaAVR MCUs like ATmega8, ATmega88, ATmega168 or ATmega328. It is a 3rd project in series of MBAVR familly home-made boards in order to create an nice environment for rapid development. I did … Read more

[MBAVR-2] Minimalist development board for ATtiny2313/ATtiny4313

This is a quick how-to guide of making a minimalist development boards for MCU of tinyAVR, like ATiny2313 or ATiny4313. MBAVR-2 is a second project in series of MBAVR family home-made boards in order to create an nice environment for rapid development. All I did, I did at home. I used toner transfer technique for … Read more

[MBAVR-1] Minimalist development board for MCU of tinyAVR family (i.e. ATtiny13, ATtiny85, etc.)

This is a quick how-to guide of making a minimalist development boards for MCU of tinyAVR family like ATiny13/25/45/85. The idea behind this project was to create an environment for rapid development. I’ve been designing many projects based on this little MCUs and I didn’t want to wire it all up any more by hand. … Read more
