- This chapter of the DIY-SMU project demonstrates the new enclosure front and rear panels, developed with DipTrace, FreeCad, and built by PCBWay. I show the process and tools I use to make panels.

This is wonderful. And what the heck would we do without places like PCBway. It’s like an engineers dream factory
I agree, PCBWay and JLC are game-changers. Before that, since about 2005, I used ExpressPCB for dozens of designs, and was happy with their service. I liked their 3 day turn-around. Before that there was a lot of hand-wiring and wire-wrapping. I stopped making home-etched boards in the mid 80s, too messy. Life is good now.
I've always struggle making enclosures for my projects. I'm going to copy your style and add tpu printed bunpers like the HP meters. Thanks for the idea
you are doing a great job, David!
Great job David! Looking forward for the next episodes!
The series are great! Good job!
Do you have something in mind for the next project? I would love to see you make a bench power supply.
I do. Possible next projects are: A relay MUX board, a multi-channel, low-power SMU, Rev2 of the 18b DAC precision voltage source. Pretty busy finishing this SMU now.
I've built a few power supplies, check out www.djerickson.com. I agree a power supply is a good starter project. But there are soooo many good and cheap supplies on the market now. I noticed one hole in the market: a triple power supply with USB, current and voltage controls for cheap. I worked on one in early 2019, and got as far as simulating and prototyping a design for the low-drop-out (LDO) regulator. Have early schematics and PCB. Check out my design notes at www.djerickson.com/triple-ps. I'll post the schematic and layout soon. Let me know what you think.
Thanks for sharing. I did a test with this SMU circuit. But I got output with AC noise (about 0.2V) when I used a 34401 at AC V mode. Can you give some advice?
I just did the same test and I get 9 mV. Checkout the latest schematic. It has some updates that affect stability.
@@ericksonengineering7011 Thanks a lot. I think I got the point for the noise. It might come from common mode noise.
