hak8or posted pictures of a power supply build using a 1U rack chassis:
I saw a post about using magnetic fields on the human brain to get certain reactions, and the first thing that popped to my head was trying it out myself.
…I finally came to the conclusion that I should make a proper voltage source. So I took one my old finds, a video scale thing. It has a large amount of FPGA’s…, so I took out the boards and started working on the power supply.

This looks like 2U. :)
I could not tell if it was a 1U or 2U case. :(
If you are sure that it is 2U, then I am going to change everything to 2U in the post. Thanks for pointing that out.
A “U” is a multiple of 1.75 inches.
So, 1U = 1.75″, 2U = 3.5″, etc
Definitely a 2U. I have a few in my basement rack.
Alright, thanks guys. I will fix that in the post on the forum.
