Has anyone ever wondered about the EFIE circuit shown in D17? Well I have too- so I built one. Here’s a bench demo of how it works. In the next part I’ll tell you how effective it was. BTW the e-bay version I mentioned uses a different IC, he didn’t combine the inputs!…

Initial test results look good! I have it set to max, that is, 250mV. I plan to build one more and combine the 2 circuits, add the delay timer, change the pin connections to allow 50 - 300mV(instead of 0 - 250mV), and use a relay instead of a switch….

So this is my first video ever, so sorry my weak speech and bad accent. This is my efie assembled in this easy circuit board panel and i got it working… I had some problems in finding the components to i got 2 diferent components that appears to be working aswell. these components are [...]
