RE: Too Many Development Tools: How to Organize Them with Virtual Disks!

shabaz — Thu, 24 Sep 2026 14:46:53 GMT

Update: I have been using this technique for six months now. I have 17 virtual hard disks (VHDs) by now, and I use the VHDX Manager app to switch them on and off.

Today it stopped working due to a recent Windows update (I think it's something broken they need to fix) anyway, there is a workaround which is now in GitHub and all is working fine again.

Overall, based on the past 6 months experience, I now feel this is a very good solution at least for MS Windows users, to the problem of increased PC costs, for those willing to offload unused VHDs to external disks (spinning or SSD), or even just to manage apps.

Excellent testing methodology! It’s easy to overlook meter burden and physical node differences during measurement, so using the dual-point fixture to verify the baseline first was a great approach. That LED test really proved the value of the FNB58 for low-current detection.

JC after playing with the programming did you find anything that is useful?

I'm a bit of a cynic when it comes to automating some testing. I fail to see the benefit on a VOM multimeter.

The TSP Editor has moved from an Eclipse based IDE to a VSCode plugin. Version 1.5 is released, and that works good for me

You can manage the instrument (e.g. upgrade firmware), save and restore settings, execute automation scripts

... and in this version, the script debugger works:
