    New lab gear for upcoming TōGō-Lab projects: Picked up Nordic’s Power Profiler Kit II to get a good look at low-power behavior instead of guessing with a handheld power meter.

    Setup in a virtual Win10 was easy. But getting it running on my Ubuntu workbench machine was a bit more fiddly than expected.

    Nordic's AppImage works, but not quite as plug-and-play as I hoped.

    Finished my 電車ベクトル (Train Vector) project:

    A Arduino-based board will detect the driving direction of brick-built model locomotives directly from the noisy H-bridge motor controller & switches the headlights automatically.

    Sounds simple, but due signal noise, switching artefacts & inductive (reverse) spikes direction sensing is quite hard.

    Schematics, PCB, and firmware for beta (version2) finished & working.

    Three PCBs were built & tested & the first 2 boards are now handed over for real-life testing in a model railway club.

    Lazy Sunday afternoon project, a simple *PC817 OptoCoupler tester.

    Two very simple ~5V circuits:

    1) Quick check — push the button, LED on = works.

    2) Test Circuit as mentioned in the datasheet for frequency / pulse behavior test.

    Nothing fancy, but handy for sorting out good vs questionable parts.

    Improving my test bench for future projects, I wrote a small PyQt5 GUI to control my Siglent SDG2042X from a remote Ubuntu desktop.

    It handles basic waveform setup, sweeps, bursts, presets (so you can adjust at the generator and than load down for later), ARB upload/download (not fully tested yet), and SCPI commands, also screenshots.

    I’m more of a hardware guy than a coder (for sure there will be some bugs), so feedback are welcome. Fork if you like.
