This is Taint in a less chaotic mode, with the vocals mostly buried in the mix (and effects), maintaining a whispering giallo mode throughout. It of course features his trademark high-piercing feedback noise, leaning more towards the side of "regular" noise, which I like. Rather short, so it makes for an instant replay.

I had a GaN based power converter board with broken transistors. This is a six layer board with lots of power planes. Desoldering the GaN chips is very hard so I decided to try milling the thing off.

It worked perfectly. I milled almost down to the pads leaving a bit of the package. After the milling step a small cleanup is necessary.

Currently dabbling in some #PowerElectronics design.
If all goes to plan, it should be a 5-60V ~15A bidirectional buck-boost converter, hopefully supporting USB-PD EPR.
And if that wasn't challenging enough, I decided to try to squeeze it into 50x25mm ^^"

The thermal design will get interesting, I'm currently planning for many thermal vias and a big heat sink on the underside.

After some days of component selection and tetris-ing, I'll soon be ready for the actual routing ^^"

KiCad 3D model view of the PCB, no traces, but the board is full of components. Middle left is a USB Type-C socket. Top left corner is the 60V to 5V buck converter. In the left third are many QFNs and 0402 passives. The right half is dominated by a huge inductor, some MOSFETs and many MLC capacitors.
Screenshot of the PCB editor, showing the same board (see previous description)
Screenshot of the schematic showing only the actual DC-DC converter part. The rest of the components are located in the parent sheet and not shown here. It's a nice symmetrical design of the bidirectional DCDC converter controller and all its surrounding components, including some design notes.

I like 7 inches, and I like random:

Contrary to what the cover wants you to believe, #5 in Con-Dom's Sermon series is called "Love".

I feel there was a lost opportunity for a word play using the artist name, but I think he was too serious for such things.

Anyway, this is, of course good, as are most of the output from one of the most unique power electronics artists.
