Initially they won't have anything on the boards, so I suggest anybody interested has or develops some SMT skills before proceeding with this set. For the future, I'm getting quotes on PCBA service to cover the 5 smaller SMT parts (there's also a couple larger ones setup for easy hand soldering that don't need any special skills).

Thanks,
Josh

I'm definitely interested.

(glances to the left, then to the right -- coast is clear, SPA gang isn't around yet)

Custom 3D printed feet and "panel" (bar) turn this SMU into a convenient bench tool. Actual work is done in jupyterlab / holoviews / pyvisa-py.

Please share the STL of your custom feet, I need it on my picoammeter. Thanks!

Hi,
 
At https://jacmusic.com/Tube-testers/index.html you can find under No.10 most of the digital/PC-controlled curve-tracers for tubes.
Have tried some but nothing is perfect. What i wanted is more accuracy and flexibility.

More than the kit that calls itself "professional tube testing system" in germany.
Not even grid-current measurement possible there. Nice software but Windows-only.

So i put some VXI-modules (16 Bit DAC +-40V, seven voltmeters and a PSU) together
with a selfmade relay-matrix 4-In 16-Out and some GPIB-Powersupplys.
For now controlled by Agilent-HP-VEE, would like to do that from my Raspberry.

Have also checked transistors and LEDs with it,
just depends on the controll-software and power-sources.
