QCW Parts

[alan sailer]

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 inductance.
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 network as 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 lot goes for 75$ and about 20$ for shipping in the USA. I don't want to deal with selling the
parts separately. I also don't want to hassle for overseas shipping.

Sorry.

Hi,
I was wondering were you found the code for the ramp generator? I've been looking into qcw coils and apart from a staccato that mads used it seems everyone is using an Arduino code that I can't seem to get a hold of!

I got the code from a post Finn Hammer made on an Arduino forum.

Cheers.

How much is it for the 6800uF capacitor??
Also, Where do u live and what will shipping to India cost??

TDAF,

I guess I should have made it clearer that I am selling the lot.

Good luck.
