LEDlogics is open-source hardware. This means you can customize the board to your purposes.
You can download the project and try out the starter kit yourself from OSHPark.
A shift register is maybe the most basic building block of addressing multiple bits of LEDs. Projects with a 74HC595 are often discussed in basic Arduino examples too. Shift registers require a number of wires and signals already: OE for chip enable, CLK for clocking the serial input, SER for the data and LATCH for activation of a write access.
Serial and parallel connections are most basic ideas in communication protocols. I was lucky to meet Robert Patterson on the Arduino Forum who had the idea for the following setup with a PCB.
What followed were more experiments on ordering PCBs, wiring and soldering. Also, buying parts takes a bit of learning.
In order to reduce time for testing, I used some simple SVG graphic for the board. As not many datasheets and components are prepared for web sharing, I published its code in a project Pinboard.js. Most likely, this project to draw hardware will join forces with Circuit.js.
This is an example of the current board. My soldering skills are not yet perfect, but the sourcing components has improved in the meanwhile.
