To blog continued live, I will write quick reports of the ongoing work on projects. Time goes by, work in full swing. Now think over circuit controller for each motor, build a test circuit on the breadboard. When everything is working as it is necessary and there would be issues - Develop PCB. For the tests had to buy L297 chip at a local store for the full amount (4,75 €), as previously ordered 5 chips with China (4,50 € per 5pcs) successfully lost in the bustle of Christmas somewhere on the way. While I bought only one, for the driver for the one motor it will be enough.
Creative mess :)
Now I calculate termination resistors for current measurement in motor windings to control congestion, think how to modify the build ready L298 to connect them.
