WiFi Pineapple Mark V Repair
I recently got a WiFi Pineapple Mark V from eBay, for about 15€ or so. Although the Mark V has since been superseded by a superior model, that is still a very good price. The main reason for this is that it has a defective power connector and can now only be powered by USB.…

Reading a Switching Regulator Datasheet
Companion note to the WiFi Pineapple Mark V repair. The dead part in that repair turned out to be a Fitipower FR9888 step-down converter — a chip I’d never heard of, on a board with no obvious markings pointing to it. Finding and reading its datasheet is what actually solved the repair, so here’s what…
Laser Diode Safety Classes, Explained
Companion note to the DVD-burner laser diode extraction project. That project pulls ~100mW diodes out of old DVD burners — well past the point where “just don’t look at it” is an adequate safety plan. Here’s what the class ratings actually mean and why it matters. The IEC 60825-1 classes, briefly Laser products are classified…

I’m an engineer who’d rather build the thing than talk about building the thing. This site is the paper trail — the working builds, the failed revisions, and the reasoning in between.Ich bin Ingenieur und baue lieber, statt darüber zu reden. Diese Seite ist die Spur davon — funktionierende Builds, gescheiterte Revisionen und die Überlegungen dazwischen.
