I have a pretty nice assortment of parts left over from my successful QCW build. Basiclly I followed loanocaens design.
For sale are;
1) two large electrolytic caps 10,000 and 6800uF/450 volts. 2) two ferrite toroids for the buck inductor. 3) a built up two IGBJT switch circuit for the buck. This part of the package could use some re-work to lower the ionductance. 4) a solderless breadboard with most of the buck control circuit. 5) a vectorboard soldered driver with a +/-12 volt power supply.
Basically this is most of the buck circuit for loaneoceans QCW 1.0. You would need to wind the inductor and add the R/C feed back networkas well as a PWM input for the ramp generated by software. I have code for an Arduino Due that I can also send you.
The whole mess goes for 75$ and about 20$ for shipping in the USA.
Cheers.
