I code for Apple platforms, build things that move and optionally push melted plastic through a hole. I like Star Treks and Missions Impossible. I made Headlines RSS for iOS (https://macbirdie.net/headlines). Señor iOS dev at @AppUnite.
Checked out the ADP-400DR PS5 supply again. All critical components were measuring fine, and with the symptom being that there is no PFC at startup, so it wouldn’t output 12V at all in the end, I thought that replacing the DAP053T with a freshly arrived TEA2016AAT would fix it and it did. 😍

If you ever bend one of the left (looking from the front of device) leaf spring contacts on the DualSense Charging Station, and you are not able to bend it back or it breaks in the process, don’t fret as the two right ones have no function in the charger so you can borrow one.

If only there would be a way to edit one's posts. I screwed up all the chip markings. First of all, the one on my power supply is LTA2016. And the candidate replacements from MPS are HR1210/HR1211 or HR1270/HR1275. Sorry about that.

And here is the cause of white light missing on a PS4 Pro. Already replaced the broken diode with a fresh one and I am left with a supply of white 0602 side LEDs for years to come. 🤷♂️

This is a diode bridge or, as we sophisticated Poles like to call it, Graetz Bridge. It tried to ruin an otherwise perfectly fine, although extremely dusty, PS4 Fat. I bought the console in a „not working, no response” state, hoping it would mean a supply repair, and bingo!

I haven’t been using my Arduino Nano clone-based stepper tester for a while now, but decided to mod its usb-mini into something more modern.

Finally bought my first split keyboard (silakka54). Despite needing to learn to type again even though I've been preparing for this to not cross the split boundary with neither hand, it made sitting at my desk feel so much cooler.

You can just mod things. Granted, some hot air and microscope work needed.

Made a Pi Pico infinitely less annoying. Those microUSB to USB-C conversion boards are pretty cool!

Nice jail you got there, ps4 pro, would be a shame if someone opened it using some obscure Japanese visual novels.

Bought a Dualsense controller destroyed by a FIFA rage quit to the wall. This is going to be interesting. Doesn’t turn on, doesn’t charge. I suspect main IC reflow or reball is needed.

My kid made me an Ellie minifigure, as he’s seen me play the game recently (unfortunately). Tried to spare him the gore, so stopped whenever some action was going to happen and I just explored the environment, solved the puzzles and enjoyed the views.

I really like the new Apple design language, the implementation needs some tweaks for sure, but this is funny

Yeah, I'm genuinely curious how they made this part for it not to break after a week of abuse by kids. Probably a similar design to dock's port.

A few more and my urge to return some fixed Switches to the world will be somewhat satisfied.
