Hi all,
I posted about my power supply before, I'll post plans once I reproduce it in the carlsbad lab. I guess make it an instructable in addition to openwetware page since that's maybe the best way to get it out there. Some brief notes,
a) I don't think the "hi voltage nixie" supply will work. It is not high enough current. Compare to bio protocols and this should be the conclusion.
b) plugging directly into the wall is a really bad idea, although there are published journal articles about this (ummm what? yes peer-review/editors are that silly).
c) using an AC transformer is costly and heavy and bulky and doesn't provide the below point by itself,
d) the power supply should have current limiter in addition to thermal shutoff. Easy to add to the design and much safer.
For home/kitchen use it's best to plug into a GFCI outlet too...

I'm extremely dense when it comes to electrical devices and how they work. I need a power source for my electrophoresis chamber, but even used ones on ebay seem too much to justify. Is there a safe way of using a battery or otherwise creating a makeshift power source relatively cheaply?--If I understand the process correctly, one only needs to polarize the water in the chamber creating a positive and negative side, but to what degree? How "polarized" does it need to be? I hope my lack of knowledge in electrical terms doesn't make this question too hard to understand.Thanks for taking a look.
