He's up, we talked, he understood everything in about 3 minutes that it has taken me 3 days to figure out. Then he reminded me of the only rules that were given: No live animals No open flame No batteries larger than a D cell. (He still doesn't know if that is larger in physical size, or larger in ...

Thanks for the clarification. Posts 8-10 had me confused on that matter, but reading your clarification and re-reading those posts, I think I'm getting it. But, every time I think I've got it, I don't! So, for the sake of education, say I'm using a battery charger with a car battery for electrolysi...

So if I add a resistor as suggested, that actually increases current /amps? Like holding your thumb over the end of a water hose to make it spray harder? No, adding a resistor increases the "restriction", which reduces the current flow. But I earlier recommended using a low resistance tha...

Doggonnit:confused: Maybe someone here can explain why it is necessary to measure angles in 10th of degrees???:confused: :confused: I have had excellent experiences using only 1/2 degree increments. I use the "MiterPro" for all angles other than 45 degrees. The MiterPro is manufactured so...

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...
