So when you say "current", do you mean "amperage"? In terms of volts and amps, what is "current"? And my personal hypothesis is that various voltages all at the same amps will result in no difference. My son's hypothesis is that it will. I haven't told him my hypothesi...

A 1ohm resistor in series with a 12volt supply will draw 12amps of current or said another way will dissipate 12watts of power. E=IR while P=IE Where E = volts dc, P= power in watts, I=current in amps and R=resistance in ohms. Example: I=E/R = 12v/1ohm = 12 amps What am I missing? Yes, if the 1 Ohm...

A couple more thoughts:

1. Make sure that any 1 Ohm current-sense resistors are rated for at least 1/4 Watt. A 1/2 or 1 Watt resistor would be preferrable (so that they won't get hot enough to burn you).

2. Make sure that your wall warts all have DC outputs. A lot of them have AC outputs.

Heath, I don't know much about electrolysis, but JPG is correct that you can really only control the voltage (without a much more sophisticated setup). So you have "wall warts" at three different voltages. A good start. Keep in mind that the wall warts are constant-voltage sources. If rate...

I gots one of those. Makes a lousy level(gravity does not affect indication)! Hard to read to .05° also!:D OK, so ya gotta turn the round part by hand until the bubble is between the two little lines. Personally, I kinda like doing that .. nice and tactile. ]http://www.starrett.com/metrology/produc...

I have observed the same 'stickey'/'repeatable' issue with the Igauge which created the same consternation. I had not paid attention to the arrows. Thanks Yet another reason that I prefer high-quality analog instruments. ]http://www.ebay.com/itm/Starrett-PR-1224W-Cast-Iron-Reversible-Protractor-Hea...

It started out as an image search -- a fairly new Google feature. You give it an image file, and it searches the web for the same or similar images. Go to Google, and click on the "Images" menu item at the upper left. This takes you to the "Google Images" page. Now the search box...

I thought that both of my bandsaws were of the double bearing configuration but they are not. I went to the shop this morning to shim some bearings on a squealing bandsaw only to discover that it has the single but wider bearings (I think that is the original configuration) . Well, dual bearings or...
