Hey Guys,

I have a blast psu that i recapped because the voltages were weak. After the recap the voltages have been great but very erratic. Both the 5v and the 3.3v will jump up and down ranging between 4.8 to 5.04v and the same is true for the 3.3v. Any suggestions on what to look at? Thank you.
 
Have you reflowed solder to the 5v and 3.3v pots? My 5v pot was super loose and it was messing with my voltages. It ended up breaking off and I had to totally resolder the shorter pins.
 
ended up being the caps on the blast i/o. someone must have changed them to a smaller size, right when i changed them to what they were suppose to be she holds steady. Thread below.

Thread 'Blast city IO and Naomi'

If anyone else was having difficulty getting Naomi with netdimm to run with blast city even after power supply recap I found the solution at least in my case. I just recapped the blast city io, and my voltage drop pretty well disappeared completely and Naomi works great now.mind you it was a pain for some reason to desolder and get new in as they were very tight through holes
