Need help from former MFS (MyFreedomSmokes) customers
Has any found a supplier or company that has tobacco e-juice like or very similar to MFS Turbosmog, Tall Paul, or Red Luck?

It is UV curable Ink. Same stuff the pros use. You would print out the solder mask page in the PDF on some transparencies put you ink on then line up the transparencies. Then hit it with some UV light. Not too many home board makers go to the trouble. Turned out to be harder then i thought it was going to be but i am close to getting it perfected. I made this Uv led board to cure the ink with a 100 bright UV lights ($ 4.88 for a 100) . UV ink in small batches is pretty much a ship from china thing. I could only find it by the gallon here in the states. IF you enjoy making your own boards it might be worth it to you to get a set up going. I went the cheap way with the LED's but they do work pretty well. I will throw in some links to the stuff if your interested.

I can't believe there is not a single US based soul that sells small quantities of UV Curable solder mask. It seems like it would be a heck of an opportunity for someone to make some money. Even if the stuff cost $700 per gallon a person would clear $3k per gallon selling 10cc for 10 bucks on ebay.
I'm going to make one of these to cure my UV solder mask.

Jrm850, Do it up. I wish I had the entrepreneurial spirit. (I'm to afraid to take the risk.) My mind starts racing, what is the shelf life of the product? Is it considered hazmat when shipping AIR, what if it gets exposed to light... can I afford to lose $700 USD as appose to make $700...
And once again I screw myself.

Sorry guys got busy and havent had a chance to do the testing yet. Going to try to get it done this afternoon.
If there is a place that sells small quanities here the states i cant find it. I am usually pretty good about finding stuff. Really not very easy to find by the gallon either. The peal able latex solder mask is pretty easy to find not sure how that is used or why but digikey and mouser carry it.
I think you should make every modder on this forum one of those flash lights So dont forget about us when ordering those parts.

I'm gonna need two of those flashlights. One with UV LEDs and one to be used as the headlamp on my bike.
I was able to grab some 22 gauge mil spec wire from my fathers office today. This stuff is great. The insulation dose not melt from the solder iron, even when I took a bic lighter to it. It did not even catch fire or degrade at all.
Much better then the radio shack stuff I was using.
Part Number: M55021/E22-C1-2U
The wire is Red and Brown twisted together.

The 47k with a diode got me down to 3.67 volts under load Without the diode i got 4.5 volts . So the 47k would be a better choice for those who want a lower low end voltage. I might be making a digikey order tomorrow if my funds come threw . so maybe by Friday i can slap one together with all the proper parts on the list.
OK just so no one gets confused. The 82k that gives me 4.5 v is with NO diode and NO load.
Whats the high voltage? I still dont understand how these RES calculate.
No high voltage. fixed at 4.5 (unloaded). The resistor is between pin 3 and 4. that's not where the spec sheet says to put it. It is there so the chip will go below 5 volts.
There is a resistor chart ( somewhere in here) for what voltage you will get but it is for those using an output diode. You don't need it, it is only there to drop the voltage by about .4v and they do take up a lot of real estate.

Thanks Gummy. I thought you might have been working with the PCB java designed.
So you leave pin 1 to pin 3 open no pot or resistor and just slap a 82K between pins 3 & 4 and that gives you 4.5 volts?
Not really much more testing i can do till i get more resistors. All i have in the range i need are 10k 47k and 100k. Hope to make a order tomorrow when/if i get paid. Also wanting to try out a 200k pot on this joker see what effect that has.
YUP, that's it. I think the range of resistors to do this is 62k to 100k.
Parts are in from DigiKey. I'm going to start my build tonight.
Wish me luck, I hope I can get the SMD components soldered. They will be a first for me. I'll have to lay off the caffeine for the rest of the day for a steady hand.
