Synsonique Drum

July 10, 2017

This is a remake of the classic Synsonic drum.
This one is pocket size, 92x76mm and uses touch pads instead of piezo sensors.
You play it with your fingers.

And it uses the TinyAudioBootloader so you can upload new firmware and drum sounds through the audiojack. No programmer required.

4 Drum sounds with touch pads.
Tuning knob.
Runs on a CR2032 battery.

A great rainy summer day project and probably the easiest DIY kit ever made.
Great for beginners.



Summer Audio hacking with the esp8266

July 4, 2017

Wemos Audio

Today we start a series of articles on creating synthesizers with the esp8266.

The esp8266 is quite powerful for audio applications with a CPU frequency of 160MHz and 4MB flash and easily outperforms the Volca Sample with a WiFi/Web GUI.

We will use the Wemos D1 Mini board with the Arduino IDE and all the source will be available.

The series starts off today with creating the 44.1KHz, 16-bit PDM Audio DAC.

If you have no clue about soldering but still want to follow you can order the Wemos D1 Mini with a 3.5mm Audio jack prebuilt.

Order the Wemos D1 Mini Audio $10

Here is the series

Happy hacking!
