My hubby has used your wonderful detailed diagram to build me a box mod. The high end voltage is too high. Like 15 volts. Please advise.
Hi would love to try have you a parts list?
You are very talented in making your mods and your calculator. I am very impressed.You sharing this with all of us is a blessing, keep up the good work. All your hard work will someday be rewarded, I'm sure.I read your out of work, you should put a Donation link so those who benefited by one of your ideas or creations can reciprocate.
the chart shows pretty limited Vout bands, nothing like 3.2->6, I guess that was the real curiosity. How you got the wider voltage band in this one.
Copper V.V. Mod. Using One 18650, 3.7v. battery Incorporated the PTN04050C regulator and a DS-18689-100 Digital potentiometer.
Voltage in = 3.7v to 4.12v, Voltage out = 3.54v to >6V
Hi all ....,This is my first post, and I want to thank BREAKTRU, for opening the doors of this place of meeting, and for all their schemes and advices he offer.I also want to say that my English is very bad, please keep it in mind. Well, now, speaking of mods, some time ago I gathered all the necessary elements to build VV mods. I started with the basic scheme PTN04050C DS1869 (2 buttons) Led Display, all mounted on a protoboard and fully functional.Now, I want to place everything in a plastic box like those used BREAKTRU (the largest). But my intention is to mount all components on a PCB, which I'm designing on Eagle software (after more than 20 hours to follow the tutorial to learn how to use it, quite stressful, but now I am able), but it will take some time to finish for sure.In preliminary tests came to me several questions, if anyone can help me understand certain points I will be very grateful:1) My idea is to incorporate a master switch, attached close the mass of the battery, and what I have on hand, is a classic on/off slider switch, as the classic on / off switch that bring the standard battery boxes from madvapes, ebay, etc. But I understand that this switches does not support a lot of amperage, but then again, I also see many other modders assemble their mods in these boxes that bring this switch already installed, and have no problems, then ... What should I do? Should I put a switch suitable for 2 or 3 amps ? or should I put a mosfet ? or simply use these common cheap slider switches ?2) In addition, I also like to add a button to turn on / off the display and the 2 potentiometer buttons.I thought about putting a little button between GND, and GND pins of the display and the 2 tactile buttons.But .... Is it correct ?. Should I put a n-mosfet ?Thank you very much !!!Greetings ....
Welcome aquiles,It's my pleasure to help out where I can. Your English is excellent.(1)The slider switches that come with the battery boxes are usually somewhere around 0.4amps. In my first several mods I replaced them w/ 3amp slides. I recently stop replacing them. Normally the switch is either on or off. Burning up the contacts would happen if you switch it on or off while you were holding the fire button causing arching which I doubt will ever occur. I haven't burned out any yet and I use mine daily at about 2.4 amps.The 0.4 amp slide has a CONTACT RESISTANCE of about 50m ohm typ. and a 6 amp has a CONTACT RESISTANCE of about 10m ohm. I don't think this would hurt performance.(2)Not sure exactly what you mean about 2 pot buttons.For a Digital Meter, I would use a low current slide.There's two ways to go: a) Two position switch: Positive from battery to center post of switch and top post of switch to pos of DM leaving bottom post empty. (Meter ON/OFF) b) Three position switch: Pos of battery to bottom post of slide, center post to DM positive and Output from regulator to top post. (center is off, bottom slide position is battery voltage and top position is Load voltage.
I removed the circuits that you posted and attached them. I only allow viewing of my circuits to members. Attachments can only be viewed by members.Ups... Sorry.. did not know. And users can also attach files?The first circuit is good except for the fire button. The way you had it would keep the 04050c powered up w/ the on/off switch on. By moving the switch to the 04050c input would save on battery life a bit.Yes, but that way I can not up and down the potentiometer or test the "V out" without pushing the fire button. Or am I wrong?The second circuit would work. Just don't know why you broke the Up/Down switches too.It is to avoid pressing the tactile buttons unintentionally. Anyway, the other design, the suggested by you, I like more. I think I will go for that, only remains, where to situate the fire button.Note:Make sure your low voltage range does not go lower that 3.5v or you will lock the Digital Pot up when using the Digital Meter.The D.P. Operates from 3V or 5V supplies but w/ the meter ON, will cause the DP to be stuck at low end and will not increment.Thankyou for the explaination, it happened exactly that, and did not know why. Till now.
dear sir, i cant see any schematic diagram, can u send me please
How long is this thing? I am looking at doing 3 vv mods in aluminum and the tubing is between 4 and 5 inches long and around can be drilled out to around .9 inches. I do have 4 PTn4050c on the way. Was looking at putting in a meter possibly and maybe a touch for fire and one for up and one for down. Unless my tube is to small, if that's the case I can leave out the digital meter and go with an analog pot with single touch or push button switch.

Looks like this is going on hold for a while. I have 4 PTN04050C chips on the way, and the tube cut for the mods. I do not have them drilled yet and don't think it is happening. Realized when I went out to pick up a test board transistors, resistors, wire, and pots that I was getting in way over my head. Came home from Fry's with nothing. I ordered a provari instead, and my wife told me she was waiting for me to figure out that trying to build my own was going to be above what I can do. Then she lays it on my that she is pregnant. My jaw dropped and I realized that the provari was the best choice for me at the moment.
