Yes, it is, on request from Uwe. He didn’t made it public on his page but if you ask politely you’ll get it (I got it because it was a big help while developing the Python GUI…)So, firmware is also Open source. Something that Locy_Z development lacks. Very interesting Tube Kiddo. Thanks for the head-up!
Many people have a currently working Locky_z curve tracer. Including me. So the answer to your question is: Yes.I just wonder if somebody have a curve tracer (Locky_z) currently working.
I see TubeKiddo!Yes, it is, on request from Uwe. He didn’t made it public on his page but if you ask politely you’ll get it (I got it because it was a big help while developing the Python GUI…)
If you look into my Python code you’ll see howto communicate which the Arduino.
Hi Mark,Many people have a currently working Locky_z curve tracer. Including me. So the answer to your question is: Yes.
The answer to your second question is, yes I will sell it to you for USD 2500. No I will not offer a money back guarantee against shipping damage or software incompatibility.

Sounds nice!If you and Uwe are keen to improve the project, I can contribute with my double peltier fine controlled temperature environment for the DUT with a BTL design. Not only for semiconductor but for NTC alike...
I was aware of this, dear mbrennwa.In the meantime if you are looking for a curve tracer wit temperature control for the DUT, see here:

All source code is available. Everybody can start improving. I am satisfied with the result it does what I need!(…)If you and Uwe are keen to improve the project, I can contribute with my double peltier fine controlled temperature environment for the DUT with a BTL design.

Let's se how things are evolving!

If your ADC/DAC (s) can be addressed via SDI, EVERYHTING you need to control this via a PC is available. E.g. there are ready made Arduino libraries to control this. And IK that an Arduino can be addressed rather easy by a Python client software. The Arduino FW source code is available and there’s enough flash space available to add add’l functions. There are also some add’l I/O ports available.I was aware of this, dear mbrennwa.
It is based on a heavy block of cooper with a lot of temperature intertia and a kind of temperature resistor heaters.
Mine, is based on peltier. It has some advantages (and maybe some drawbacks).
But, in theory, it is possible to maintain a target temperature for a discrete DUT with a reasonable size and temperature load.
Attached, it is the PCB design based in a double push-pull stages, 16 bits AD, 12 bits DA, precision current generator (For tracing NTCs, this is the original purpose) and 5V 2A (Reversible and continuous) hot-cold peltier stage.
Also, some SPICE curves showing linearity from -5V to 5V Peltier feeding. Power supply is only +5V due to the Bridge Tied Load final stage without zero cross distorsion.
Some curves from my GUI attached. It also has a rudimentary matching function (incl. complementary pairs).

Which Python libs did you use for GUI and data communication?
