Hi John,

I just watched your video demonstration - it works great and I'm glad you decided to enter it in the test instrumentation contest. I made an order this evening using the prize money from the solar competition and included what I need to make something similar but put my own spin on it. I have so much going on I'm not sure when I will get to it though :-).

John,

Very nice project! The video proof was great too. I really will have to take a look at this, as I have been wanting a DC load for a while now.

Thanks for sharing this great project.

Nice Case design format John things look good and the electronics are to a high standard too . I would suggest you follow Shabaz's recomendation and put it forward for the Project 14 so it could reach an even higher audience.

Good one John A

Great project and build, thanks for posting. The finished instrument has a very neat professional look to it.

Kind regards.

Hi John,

I really like the look of it - that is something I have been working to improve on my own builds.

Hi John,

Another nice project, and great documentation!! Maybe it should be submitted as a DIY Test Instrumentation project for Project14 : ) you just need a short video I think all other criteria are met but [mention:44fa45702fda4d95b457f69505107f36:e9ed411860ed4f2ba0265705b8793d05] will know for sure.

If you've got room to rotate the heatsink, that could be worth doing too, and maybe (with say a thin sheet of board) a kind of duct for the air to be forced along the channels could keep it cooler still (or maybe that's overkill).

The front panel looks really good.. the multi-turn potentiometer is a great idea too!

Nice build.

Great to see you've stuck with the common size box, although your design has deviated, and the power switch is on the other side [View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-5340506a-4683-4803-8548-70d796fe623c/contentimage_5F00_938.png:16:16]
