Excellent DC Power Supply

[Wralyn]

Here is the DC Power supply I use to make CS and CG and it works perfectly for me! IT has constant current mode (good for CS) and constant voltage mode(good for making CG) and its the cheapest ive found for the functionality it offers! You can buy it here at Amazon.  http://www.amazon.com/gp/product/B004ISQ270/ref=as_li_ss_tl?ie=UTF8&tag=mygolfgpsrevi-20&linkCode=as2&camp=217145&creative=399373&creativeASIN=B004ISQ270

oh yeah just FYI you can also get your beakers, alligator clips, and Carbogain (maltodextrin) on Amazon as well!

I love Amazon!  But another good source is sciplus.com for glassware.
That power supply should work well, but for CS, you really need a good milliammeter since the built in one only has 2 digits.

True but i just set mine to .01 milliamps and wait to hear the click of the little transistors things inside there. but yeah it would be better to have one more digit just for the sake of accuracy! For colloidal Gold it works just perfectly as i just set it to CV mode! but yeah would be cooler to have one more digit!
