Today I pushed my 1 GB VPS over the limit by running #Nextcloud, #Matrix, and #Gitea for togo-lab.io and adding #ClamAV AV scanning as an experiment. It crossed the line due too much load during scanning, and my system crashed.
Maybe you’ll find my post-mortem useful.
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.
