Revision as of 15:57, 20 February 2022
Experiments carried out in the past (from 2011) are described hereafter: 2021, 2020, 2019, 2018, 2017, 2016, 2015, 2014, 2013, 2012, 2011
February
- Playing with one of my Colorlight 5a-75B v8.0 board.
- Those boards are fitted with a Lattice ECP5 FPGA that can be programmed using the opensource yosys + Treillis + Icestorm + abc + nxpnr + ... toolchain.
- I use it to drive a HUB75 64x128 led panel that uses a ABC addressing scheme. I have managed to display an image, but there are still some timing bugs (the blue line in the middle of the image is not expected...).
- More information can be found here.
January
- Making a box for my "laser game" using FreeCad and the "Laser Cut Interlocking Extension":The aim of the game is to shoot "asteroids" using a "ship" that you can accelerate and drive left / right. It uses a laser galvo and an Arduino. Some details can be found here.
- I am investigating building another "game" using, this time, a LED display (those described in Quoi de neuf 2020, December). See e.g. here.
- I have designed a basic PCB to implement the NRF51822-baased door-/window- opening detector.
- I have spent some time investigating at the extremely cheap PADAUK chips. Unfortunately, the cheapest ones are not available at the current time (absolutely simple)...
