I only just learned of this site today from a cross posting on our hacker space about a new tutorial for KiCad circuit design. I haven’t found the tutorial yet, but I did bump into this thread. Many projects that occasionally get worked on. Ones that aren’t pure software are:
Very far behind schedule doing a single phase to three phase power converter for a friend to get an old lathe he purchased up and running,
Experimenting with making 3D printer extruder heads from glass tubing to reduce jams, make it easier to pull cold plastic out, and remove need for thermal insulation between heater at the tip and the mounting to a plastic extruder framework. At the same time trying to finish a Prussa I3, fix a commercial 3D printer from the school of the high school robotics team I mentor.
Making an electronics support board for an Arduino Mega based clipboard robot. I want to build and write a book of ‘experiment’ for programming and modifying robots that aren’t so scary that kids think you need to be a rocket scientist or have a PHD, but still be capable of a wide range of robotic activities, including blinky lights, making the LEDs brighter or dimmer, blending 3 LEDs ti make white. But also motion based experiments like driving in a square, running a maze, following a light, edge detecting a table top to move randomly without falling off, small robotic arm, ultra-sonic range finding, incorporate an axcelerometer/gyro package to improve driving in a square, remote driving with IR remote, etc. I am hoping a kit of 10 to 20 clipboard robots plus 3 to 5 kits of all the extras needed for the more advanced experiments so that a middle school classroom could all learn/experiment together and maybe some will be more excited to go into high school robotics.
I still want to build a working underwater ROV. I was in a competition for several years but never quite got it to work and I would like to prove that I can and have one to play with. It has given me a lot of experience at roll-your-own H-bridge motor drivers.
Occasional thoughts about excessive projects like individually accessible LED lights for winter icicle lights, or flowing 2D pattern LED T-shirts.
Well, that should be more than enough to start!
