Day 21: Trying to decide controller specification
More progress on the controller, I've managed to put some code together to make the controller respond to a potentiometer, operating as a centre-off (as I prefer that to having a reversing switch). Experimenting with throttle curves and various amounts of dead zone in the centre too, so it buzzes less and has nice smooth control at lower speeds.
So the next part is to make this all into a nice neat PCB. I've started on the schematic in KiCAD (free PCB design software), and so far I have the following additional specification:
- 12V aux connector (for powering lights etc.)
- Additional reverser (in case I wire up a motor the wrong way round)
- Two terminal block inputs for additional inputs (might run a shuttle in future)
- Additional switch input (for some sort of future expansion)
- erm... Tea maker? Heath Robinson sandwich constructor?
Stats:
Projects I've started to avoid having to paint a backscene: erm... at least 3
Adequate reasons for making a controller rather than buying one: Not enough... apart from fun
Cumulative pushup counter: 2275
