Hi mate .i watched your mit portfolio video. That was awsome. If i were to start learning electronics and robotics, what resources would you recommend?
Thanks for the kind words! I would recommend following some tutorials for KiCad (the software I use - in my opinion it's the best free one) to make some designs, and then to make one for yourself from the ground up.
I want to convert a 85v DC from solar panels down to a usable voltage but I can't find a Buck converter for a reasonable price. I had the idea of using a 90v max DC PWM motor speed controller and using the output with a transformer (with a diode and capacitor to depolarize the transformer between pulses) Do you think it will work?
Yeah, I totally think this could work. You'd just need to consider that the duty cycle and the transformer gain are influencing your output voltage, but that's quite simple and I'm sure you've planned for that. I recommend that you use multiple, different types of capacitors with capacitances related by thirds (one cap has 1/3 the capacitance of another cap) for better ripple rejection. Good luck, and tell me how it goes!
