No donations! I'm a dang charity case. hahahaha. Rama-lama-ding-dong, you should save your money. If you want a board though, I'll put you down for $20. The good news is, I just copied the powerex design, so there's no way it's wrong. Usually it takes me about 2 tries to get a board right.

Paul,
I'm adhere to the cause to.
Please PM me if I can be of further help. I'm sure that Jackbauer will do to as soon as he will find out.

Paul,

What service are you using for the boards? If you can figure out how to make designspark export the gerber files properly, BatchPCB would only cost about $20 per board in any qty, Plus the $10 fee. Thats it. So you could just get the 3 that you need for the AC controller for $70... A little bit better.

Well it seems to me that if the Darlingtons couldn't handle the frequency they simply would not have operated correctly and would have been either full on or just off but the board seemed to turn the wheels fine on jack stands so it seems that they did "handle" that frequency I would think that if it were the frequency to the transistor all would have blown up not just one it seems indicative of over current I would write in the wiki how to test the comparator and NAND if I knew how and other components. It would be nice if Paul sold the just control board assembled and working. As the mosfet was switched by the control board it sent a positive +12 volts was sent to the bases of the Darlingtions turning them on and off. I still think it would work do you recommend anymore tests?

Hey Paul,

Send me the DesignSpark Driver PCB, I'll extract the gerbers for you and post them on the Wiki for anyone that wants them.

No problem. Just tell me when and where.

The advantage of going with the chinese company is that it's $20 for the first 5, and then any order after that is going to be like $7 each in tiny quantities, because the setup fee won't have to be payed again, and it's $1.50 each in quantities of 75, which is only like $120 or something for a lifetimes supply. haha. The disadvantage is that they will soon own us and make us their slaves.

well, if we put an order for 35 initial pieces, our cost will be $315.00 including the set-up fees plus shipping, for a single pcb price of about $9.00. I can buy a bunch of boards and act as a supplier for them.

it's acutally $139 for the first 35 (including the cost of the tooling fee and shipping). haha. I guess that would be better than getting 5. lol.

Hey i just posted that to the wrong thread on accident. no wonder there were no replies. hahaha
