I made this myself - quickly - and it may have errors. There are some caps not called out here - specifically under the shielding and behind the flyback, but I've never seen these caps fail. And, usually, I only replace the larger ones 100uf and larger (squared in red). Comments: 1. One of...

I've been following your project closely with much anticipation! I am selling my stockpile of PowerBook Duos (keeping just two 2300c models) and in the process of readying my others for sale, I stumbled across something that may interest you. Specifically, the PowerPort/Mercury for the...

Sure. As you may know, many manufacturers are building USB-C charging cables with PD chips in the USB-C connector end. Adafruit sells such cables with a DC barrel connector on the other end and on Amazon, you can get a USB-C charging cable for the Surface pro that outputs 15V at 3A through a...

I know this reply comes several months after the original post, but in case it is helpful to you or others... I had a board come across my desk last week where I suspect that a capacitor had been installed with incorrect polarity and all sound is missing - both from the headphone jack and the...
