Update 24 July 2019 - all 160 Digirule 2's (and 2A's) were sold within 12 hours on Saturday 20th July 2019. Due to more people wanting one, I am making another Batch of Digirules however it may be upto 5 weeks before they are ready to sell again. Sorry for the inconvenience.
PLEASE NOTE: Orders placed between Friday 19th July and Sunday 28th July will be sent out on Monday 29th July.
There are two versions of the Digirule 2 available on this page - the original Digirule 2 and the newer Digirule 2A. While they both essentially do the same thing, the newer version has new and improved firmware (written by Brent Hauser) which features two additional instructions and some handy shortcuts to make coding on the Digirule 2A a little easier). Both the Digirule 2 and 2A can be seen in the image above.
In the early days of personal computers, programming in binary was the only game in town. Systems such as the Altair 8800 gave the user a bunch of switches and LED's with which to interact and program the computer - those were some exciting times in computing history!
The Digirule2 is essentially an 8-bit binary computer of the 1970's, built into a 20cm ruler. It features an 8-bit address bus, 8-bit data bus, data input buttons and 33 instructions for you to code your own programs.
With an instruction set consisting of 33 instructions - the Digirule2 can be programmed to perform all sorts of tasks, including fun games such as the classic 'kill-the-bit' game for the Altair 8800 or perhaps a Knightrider LED scanner, binary counter or a simple game of two player pong!
An excel spreadsheet allows you to easily write your code in mnemonic form - it will then automatically convert it into binary machine code for you to enter into the Digirule2:
The Digirule2 is completely open source and all files including source code, schematic, PCB design, bill of materials and gerber files are available to download from bradsprojects.com/digirule2
