Thermal printer now working. Required a consultant. Not anywhere close to plug and play. Just printing dummy variables now. Next stop is controlling the instrument in the same script

Nice work! Hopefully that makes your job easier. What is the system that takes the measurement? Is it a home-built curve tracer or commercial one?

To easily trace the DPAK LD1014D I made a setup with some hightech tools,
a clothespin 🙂

 

[Vunce]

DIY for sure!
Bravo Danny

 

[Bas Horneman]

Genius.

 

[woofertester]

I like it a lot. It would require 6 wires for my setup. You can see where a part got toasty warm.

Check out what we can now do with an LU1014D/LD1014D - a 39w LuFo Amp!

Nice work, Danny! I like the clip.

Send a PM to me. I will give the link. Ali Express has genuine LD1014D for $0.17 /each

Finally have an automated process working. In total, all pieces, a couple of weeks of work. Also needed an outside consultant to get the printer working.

The controlling language is Python with several plug-in modules. The total delay added by all of the software components make the test slower than the manufacturer Eclipse-based debugger. The absolute values are some different comparing the debugger-generated parameters vs. the Python-generated parameters.

The difference between the two test methods is less than 1% for Vpinch and Vgs. I am happy to have an automated measurement and printing workflow.

I can now get started on the stash in earnest.

 

[xrk971]

Nice work, Woofertester. Congratulations on getting it all automated.
I’ll be soldering up your 16 units tonight.
Thanks for doing this for us.

 

[woofertester]

It is gratifying to have it working. It was a very long list of things to make work. It is essentially very similar to a cash receipt system for a business. That is why the hardware is not ridiculously expensive and the paper as well. The equipment and supplies are in high volume production. One nice thing about these printers is that they require no ink.
