Has anyone made the Titanium Anodizer?

I am building one and need help. I have assembled upto the rectifier and decided to test it. I get a constant 108v DC from a clean 120V AC. I haven't installed the capacitor or resistors yet. Sliding the dimmer doesn't change the voltage at all.

Shouldn't the dimmer lower the voltage at this point?
 
"the Titanium Anodizer"

It sounds like you are using plans ?

Show us the plans you are talking about.
 
how many connectors are on the dimmer switch 2 or 3 ?

and if there are 3, which ones are you connected to?
 
I built it a while ago and it worked ok, I found a setting where I got a nice blue and left it set there because it was not real accurate, since that time I bought a 0-120 v 1 amp variable power supply, set the voltage and get perfect consistant results every time.

Not sure what the difference is, may be the voltage drop difference from the setting to the actual work piece.
 
I used a resistor, I dont have any pics since its mounted in a box with the knob for the dimmer on top, you need to put a small fuse to protect the bridge on the output, I think my bridge is limited to 1 amp. I remember that I bought several resistors all in the low Ohm range and rated at +200 Watts and tried a couple to get the right one. If its too small it will burn out and if too big you wont get the output voltage you need.
 
Hmmm. Ok, resistors and dimmer. I went ahead and ordered a variable transformer. I haven't ordered the resistors yet, I could only find 100w 100ohm resistors. Since it appears one is needed to put a load on the dimmer and one is used to drain the capacitors. Since only 25w bulbs are used, hopefully a 100w with adequate cooling should be enough. I have the unit built inside a computer power supply box with 12v fan. I ordered some 12v regulators and have a couple heat sinks that the resistors, rectifier, and regulator will be bolted to.
 
This sounds alot more complicated than my set up. I just have a Variable output transformer, bridge rectifier, and a mason jar. Make a Ti boot clip last night. Just kept turning the voltage up slowly till I found a color that I liked.

Interesting. It seems the caps and resistors simply work as added filters then. I might just grab a junk multimeter and test it with what I have tomorrow.

I do like the Computer Power Supply, as it's a nice box with a fan and plugin for a power cord. Removable power cords are always nice! Plus, I have dozens of dead power supplies and power cords. Now, I just need to find a decent container that I can bolt the PS to. . . .
