More About the 2025 eChallengeCoin

What's New

The 2025 eChallengeCoin is a limited edition release.

The 2025 eChallengeCoin has three touch pads. These are not used for the text adventure game. They are provided for use with CircuitPython. There are also three groups of Neopixels - conveniently aligned with the touch pads - and a small speaker.

There is no battery this year. The 2025 eChallengeCoin is very much a 'coin' when not connected to a computer.

The driving force behind the design of the 2025 eChallengeCoin is 'simple keeps the costs down' while also supporting both a full text adventure game ... and CircuitPython.

The 2025 eChallengeCoin is priced at anout half what research has revealed as the original price for a copy of ZORK back in 1982. And, while ZORK was shipped more than 40 years ago on a double sided 5.25" floppy, the 2025 eChallengeCoin is less that 2" in diameter.

The text adventure game is accessed using terminal software and the eChallengeCoin has a USB connector. As soon as it is connected to the computer with a USB cable. it presents as a serial device.

The 2025 eChallengeCoin also runs CirCuitPython. Once you have completed the text adventure game, the eChallengeCoin is great for creating a mini macropad!
