[sdiy] Powering 4ms pod

[Didier Leplae]

I hope this doesn’t exceed the file size limit, but here is a picture of the 4ms power section if that helps to determine what is going on.
I may take Florian’s suggestion and try to return the supply that I bought. However, if they give me a hard time I’ll come back crying for more help.
