2,400 LED icosahedron (20 sided)

A tennis ball sized, 20 sided, LED clad, regular polyhedron Introduction The major challenge of making a smaller LED cube in my opinion is the LED panels. Commercially available panels are designed for video walls and typically made at 64x64 pixel as a minimum size. This seems to be a good trade off between cost/complexity/light efficiency. On my previous project mini-led-cube I had overcome one of the major hurdles of creating a smaller cube, because I had designed and built my own custom high density* LED panels....

Boson Frame Grabber Part 5

RTL Architecture The original version of the frame grabbing PCB used an iCE40 HX8K FPGA. This turned out to be a little small for the features I wanted to add. I managed to get it to a state where it would capture images from the Boson 320, but everything was hardwired together, and not easy to alter or reuse. In order to improve module reuse and extendability a standard interface should be used....

Boson Frame Grabber Part 4

The new hardware for the Boson Frame Grabber will be based around the Lattice ECP5 family. Lattice make available a free IDE for this FPGA assuming you are not using a model with embedded SERDES. Since we are not, it’s perfect for our application. ...
