AliExpress/ Chinese drsstc drivers
« on: October 07, 2017, 02:10:18 AM »
With my drsstc project on the horizon I had to start thinking about the driver. I've seen many rev 2.7c boards and the awesome through hole 1.3b board mads has created, but one thing I haven't seen are many Chinese boards being used.

My overall goal for this thread will be to have different Chinese driver boards so people can basically have another option without completely buying in the dark.

I've just ordered this board to test after I build my drsstc. If all goes well I'll order different variations and see how they go.

A lot of those cheap chinese drivers appeared on ali/ebay, listing descriptions are almost non readable so it's no surprise people are not buying them

Check out this one, it uses some kind of CPLD/FPGA

Since BOM of UD2.7C is around 60$ I'm really curious if those can be used instead

You can usually find those exact modulators and drivers in taobao for a much cheaper price. Since I'm not too entirely well verse with electronics and Tesla Coil circuits although after building one I refrained from buying them as of now. Those links in the PCB usually leads you to a Chinese HV forum which consists of many interesting builds. Here's one: http://www.hvdiy.com/forum.php

I was not even aware of DRSSTC drivers being available "publicly" like this, usually it has always been group buys of PCBs etc, I guess even the slightest thinnest market is enough for some Chinese manufacturers to set up a series, or maybe there is a huge Chinese in-land market that we never hear of?

This google translate link to the AC Tesla coil part of the forum helps understand what is going on: https://translate.google.com/translate?sl=auto&tl=en&js=y&prev=_t&hl=en&ie=UTF-8&u=http%3A%2F%2Fwww.hvdiy.com%2Fforum.php&edit-text=&act=url

The driver in the first link says "Steve-4" on it, which refers to Steve Wards 4th DRSSTC: https://www.stevehv.4hv.org/DRSSTC4.htm that used the UD1.3, which is now the UD1.3b: https://www.stevehv.4hv.org/new_driver.html

25$ is still a fine price for a populated UD1.3b driver

I am looking forward to see your tests with these drivers!
