As there is a growing number of ESP8266 base Wifi-modems for retro computers out there I decided to build one myself.
My personal feature list:
- connected to and powered by the C64 userport
- simple, AT command based interface
- usable with existing terminal software for the C64 out there
- 2400 baud (I wanted to keep the circuit as simple as possible)
- an OLED display for status information and show effect

The schematics (Updated on 20.08.2017):
The firmware can be found on GitHub, I used an existing firmware, removed stuff I didn’t need and added OLED support. To compile you need the Arduino IDE, the ESP8266 arduino core and the esp8266-oled-ssd1306 library.

In the past month I’ve worked on a little project I came up with in December: I wanted to build a game-cartridge for the Atari 2600 which is based on a SRAM and where the ROM-data is read from a SD-card. Continue reading Atari 2600 SRAM Cartridge
I came across the project of Hartmut Wendt and wanted to do something like this myself. Continue reading Mini arcade cabinet
Recently I stumbled upon a 5EUR embedded WiFi module: ESP8266-01. Because it is cheap, can be used by some simple AT-command via an UART and the documentation in the interwebs isn’t that bad I decided to order a bunch together with some 3.3V/8Mhz Arduino Pro Mini clones.

I managed to buy four Atari 2600 (two Juniors and two Fourswitch) and more than 70 games for quite a good price. Continue reading Atari 2600 is in the house

Today I decided to build something helping me to decide stuff. So I decided to build an electronic dice with an included YES/NO-answering machine.
I used a spare MSP430G2452 that came with one of my MSP Launchpads.
Below is the schematics (CC5 source code on request):
As you can see on the photo of the eDice I used two different colors for the LEDs. When pressing the YES/NO-button either the green (YES) or the yellow (NO) LEDs light up.
When used as a dice one to six LEDs show you the value of your dice roll.
I had no battery holder therefore I built one using some wires and lots of solder…
Ever since I found the arduino-tvout library I wanted to build something nice with it. When I stumbled upon this cheap SNES controller I knew it would be a game console embedded within that controller. Continue reading My own gaming system
