Making A Pickit 3 Clone

After using the Microchip tools to program and debug the projects I work on, I wondered about creating my own programming/debugging module that I could put on my own boards – just like Microchip does with their starter kits and such. As I became more interested in that idea, I began to search the web to see if anyone else had already done something similar. Initially, I found lots of posts regarding the 2nd ...

Teardown: 12V AC adapters

In the name of science, I introduced three of the worst 12V adapters (from My kingdom for a 12V adapter) to my bandsaw. What I found may shock you. Note: All pictures can be zoomed or opened at full size in their own tab. First on the chopping block, the “EH1205”. Wait! What’s this? The original AC connector is mounted to the PCB. Yes, this has been repackaged! I think we can assume the approvals on the lab ...

Open-Source SWD Programming Adapter

After making the switch from AVR to STM32 microcontrollers, I redesigned my old 6-pin ICSP pogo-programming adapter for SWD. The new design allows programming with pogo pins or a small pin header soldered to the pogo pads for debugging, all with the same cable. The footprint uses surface mount pads only, so it can be placed on even the most compact board layouts. The ST-link adapter I designed a small PCB w ...

Counterfeit Macbook charger teardown

What's inside a counterfeit Macbook charger? After my Macbook charger teardown, a reader sent me a charger he suspected was counterfeit. From the outside, this charger is almost a perfect match for an Apple charger, but disassembling the charger shows that it is very different on the inside. It has a much simpler design that lacks quality features of the genuine charger, and has major safety defects. The co ...
