Eris 2206 FPGA Computer

Sun, 30 Oct 2022 21:35:14 +0100

Eris 2206 is a front-panel programmable 8 bit computer with lots of Blinkenlights, implemented on an FPGA. It is not directly based on an existing computer design (contemporary or historic), but it takes inspiration from minicomputers and early microcomputers.

Fri, 05 Nov 2021 21:40:33 +0100

Eris 2010 is homebrew 8-bit computer in the style of the microcomputers of the 1970/80s. Here you find a little description of the project including some screenshots and a video, as well as the complete source code for the soft- and hardware.

Led Pillar: An LED covered pillar showing animations

Fri, 12 Mar 2021 20:37:20 +0100

This projects shows animations on a strip of WS281x LEDs wrapped around a pipe. A Raspberry Pi Zero WH computes the animations and provides a web interface. I got inspiration for this project from stuff I saw in the Blinkenlights area at some Chaos Communication Congress.

Blinkenstrip: Blinkenlights on an LED strip or matrix

Wed, 24 Mar 2021 22:25:32 +0100

Shows effects on a WS281x strip or matrix connected to an ESP32. The ESP32 runs a minimal web server allowing to control the effects. The system is highly configurable: It can show effects both on LED strips of arbitrary length and on LEDs arranged as a matrix.

Hearing Aid

Tue, 02 Feb 2021 07:14:39 +0100

“It's a service. Imposing no penances, it's kinder than the confessional. Demanding no fees, it's affordable where psychotherapy is not. Offering no advice, it's better than arguing with that son (or daughter) of a bitch who thinks he/she knows all the answers and goes on and on and on until you want to SCREAM.” (John Brunner, The Shockwave Rider) Talk to Hearing Aid Done
