    Hi folks. In this thread I'm going to present an all hardware DIY (Tesla) ACIM ASIC controller that does not need uC, DSP and programming.

    When I registered here, I set myself the goal to start my first conversion build in 2018. And a couple of months ago I decided to go for it after I saw the first results of €1000 DC conversion here. To do a build on a shoestring and in a short period of time, the electronics have to be simple...
