"Recently my dad made me buy some pwm to dc motor controllers (20EUR) for him, basically a servo motor setup but without the analog position and designed for a continuos motor mode. With that order I got me some attiny85s and some dual channel NP mosfets to start building something like that..."
Man I'm lazy.
- I should (read: have to ) calculate this on every project
- 1.50 EUR per attiny85
- 2x 0.71 EUR for the MOSFETs
- some caps and resistors
- 1.50 EUR pcb yet to be designed but shouldn't be much more than
So around 5 Euros give or take. Sounds much better than 20 bugs. Software will be tricky though, but since it's hobby - it's free.
