Etching PCBs With Dry Film Photoresist

Posted on January 19, 2018 The Engineer

Since I do my own PCBs on a somewhat regular basis, I decided it was time to move to a more professional method to etch my boards. I have been using the cheap toner transfer method, using special yellow coated paper from China. (I think it’s coated in wax, or

Potentially Lethal Clone Apple Charger

Posted on December 12, 2013December 12, 2013 The Engineer

I received this USB supply with a laser module from China that I purchased on eBay. I have heard of these nasty copies of Apple chargers going around, but I’d never received one this bad with a piece of Chinese electronics. Model No. A1265, so definitely an Apple clone. Apparently
