Ladder board for simple Automation

chmod775 designed this compact, standalone board to be programmed with a simple visual language:270681483106954815.jpg


Focus born with the purpose of making a prototype board that simplify every aspect of programming.

Spent the last hour writing down the main concept of the Visual Programming Language for the Focus!  It’s just a simple sketch, but I wanted to share it with you the main reason why I’m building it.

LED Matrix Generator for EAGLE

Ted Yapo is designing a display for his  LED Oscilloscope Mk. II and decided to automate the process:


16×32 Display Design

I painstakingly drew the schematic for 512 LEDs in this display, then endured the drudgery of laying out the board. The whole process took about 45 seconds. Yes, I wrote a few Eagle User Language Programs (ULPs) (elapsed time after the scripts were written and debugged). The previous time I wrote one was last century to lay out a circular LED clock face. I figured it was about time I regained those skills.


The EAGLE ULPs are on GitHub:
