The 0603 pads are just for me because i have those parts on hand. I guess i really should have went with 1206 for easy soldering for the masses. But 0805 's will be good practice. I picked up a package of 1n4502 diodes at radio shack so i will slap one of these together tonight for some testing...
Although i am 99.998% sure this layout will work. I would feel much better about it, if we tested it before ordering 150 boards. I was just looking threw my parts and i believe if i change the resistor pads to the smaller 0603 i would have the parts to do a test. I think maybe I will try and get...
I was using just a UV sanitation wand and it was taking a hour to a hour and 15 mins to cure the ink. With the LED's I Rigged up it has cut the time to about 20 minutes. But i also have to run the LED's @ about 3.3 volts or my Regulator board starts screaming. If i can get them to 3.6 or 3.7...
Ok here is Rev0122 , changed a couple things added a .020 boarder for solder masking , added one more output that can be used for a LED. Changed the dedicated Trace to the adjust pin.
Here is the PDF File
Thats a really good price on caps 12 cents a piece. But they dont have a data sheet on them. ESR and ripple current would be nice to know. The caps we ended up going with are actually smaller in diameter at 5mm ( .200") but taller at 10mm high ( .400") . They do only stick up past the highest...
Ok here we go TOP and bottom sides 1/2' wide but a little less then 1 1/2" long. Decided on a barrel diode soldered into the output that way it is optional.

Got the email, I sent a reply asking a few questions. Mainly just need to know the working space. The electrolytic caps are space hogs and required on this chip Might have to slap them on the chip side of the board ( threw hole ones) going to add to the length of the board .
They are not all that much. I got mine for 115 shipped i think they are a bit more now. But pretty comparable to just a good weller iron.
Yeah i hear you there if it is something i am interested in i am like a sponge soaking it all in.
mrengles: When you get the parts list up dont order...
Yeah threw hole for the booster but i think we can make this thing really small using SMD resistors and a Diode. Maybe even some MLCC caps. i forget if electrolytic caps are required or not on this chip i know the evercool requires them. But i can see making this thing fit into a very small space.
Thanks Madman, Yeah knowledge is a wonderful thing , We for sure are not born with it. Hell this time last year i didn't know much about electronics But i learned from here and other places on the web and also reverse engineering some stuff posted. But i have no problem sharing Info or teaching...
I have no problem sharing we can post it for all to use. I usually export it to PDF then print the PDF page with he traces. Mainly because you would get a 12 page report going straight to the printer with this thing it gives you the drills solder mask , vias, and so on all on seperate pages...
I dont have a circuit made up for the booster. cant remember the PRN04050cad one is that those balls that fit on the pads or is it the one with pins. I can help you out as much as i can. The Design CAD i use is Linux based called Geda. If you never used a CAD for electronics design it has a...
:toast: Something that can make me 5 gallons of beer in a week and also i would like to be able to vape off it. :party:

Nothing wrong with PWM's they are a lot more efficient then a VV linear regulator that are used in a bunch of commercial mods. Really doesnt matter what you call it VV VP VW in the end the only thing that matters does it vape good and how long will my batteries last. At least thats my opinion.
You talking about everything or is there once component in particular. Solder mask is going to be the grayish black pads and circles. I already fattened the 555 chip pads I would have to make a new footprint if that is where the problem is. Just let me know what needs it and what doesn't and i...
Here is revision 2 let me know if you see anything that needs tweeking. I only got the pot to move about .042 thousandths of a inch, not much room on this little board. I think it will be enough. If not we would have to move the output up out of the way. The switch side is some ugly colors now...
