Software Basic C64
I’d like to share my very first software project from 1992 with you which was written in BASIC 2.0 on my C64. It has never really been finished but had a nice intro screen with moving sprites and was able to print labels on a wire printer 🙂 In order to archive it for myself, I’ve set up a git repository where the source code is available: https://git.qrz.is/clemens/adressenmeister Here’s a little screen-cap of it: Read more...

The One Button Audiobook Player

The solution to this problem was – tadaaaah – a one button audiobook player 🙂 It basically consists of: 1 Raspberry Pi 1 ModMyPi enclosure 1 button 2 resistors (330 Ohm, 10 Kilo-Ohm) 1 blue LED 1 (slow) 8GB SD-Card some wire a pair of speakers The following software has been used: Read more...

The Laundruino

My washing machine is located in the basement. Unfortunately, the time data displayed on the front panel is always inaccurate.

This is what I needed for it: 1 arduino uno 1 ethernet shield 1 opto-coupler (CNY17) 1 perfboard 1 resistor (150 Ohm) In my case, getting the right signal from the washing machine was simple: It has a “Finished” LED on the front panel, so all I needed to do, was to solder it out and replace it with a two-core wire.
