LED Matrix

I built an LED matrix board for a future project. I designed it so multiple boards can be strung together to form a larger display. I also used SMT for the design. There are no mounting options save for hot melt adhesive. It uses the popular MAX7219 driver chip and one resistor.

Resistor Grid

The infinite resistor grid problem is interesting and I thought it might look nice on my wall so I built one. I made a quick jig out of wood and went to work. I spent my free time on this for a few weeks. The final piece is not quite as elegant as I had hoped but it’s still neat.
