HELP PLEASE!!! In need of help in picking which pots for my 12 unites that i am making.

[Xariel Luis Hernandez]

Ok I have 9 "PTN04050C" on there way to m house and 3 "PTR08100W". I would like to know what is the best square "Potentiometers" to use in these two systems because i have read and they all are different from each other. What are the spec for what i need for each device and I already have lots of diagrams for it. I am going to make some for my friends and myself but need to know soon because they come in tomorrow and i want to start on this project soon.

I personally prefer the thumbwheel type pot's. 40 turns with a screwdriver seems like a pain in the rear. I made an evercool box with the PTR08100W and used a 200 ohm thumbwheel from Digikey. I used my soldering iron to mark the 5.5v 5v 4.2v 3.7v and 3v, so I could easily adjust close to where I need it.

What are the specs that i need to look for in my two units and thanks.

I am not certain what you are asking. For the PTR08100W to get 3v out you need 200 ohms of resistance. For 6v you need 400 ohms. The size and type of potentiometer is all personal preference, I like the thumbwheel with 200 ohm because I vape no lower than 3 volts and not higher than 6 volts. The Evercool Variable Voltage mod thread is just a few down and has any and all details as far as getting it to work.

As for the other regulator, I have no idea. I am also not in the habit of doing other peoples research for them. Sorry.

 

[Xariel Luis Hernandez]

i have research for a long time but it seams that when they start to talk about pots they dont tell you much i have read the 8 page long evercool and still not enofe of information the square type pots and there ratings for the pots. I do not know much about pots or trimpots but i am trying to learn something new. i already have the caps, resistors, led's, battery boxes, switches, batteries, and boards that i need but still dont have a clue on what square trimpots or pots i need.

 

[stouchon]

Pot's and trimmer or trimpot's are all potentiometers. As long as the one you use adjusts from one level of resistance to another it should work. I use one that adjusts from 0 to 200 ohms. You can use just about any type or level of resistance, but 200 ohm is probably what you will want.

What range of voltage do you plan on using? I do happen to have two 100 ohm thumbwheel pots that I don't plan on using. When paired with a 270 ohm resistor on the ptr regulator, you could regulate between 3.5 volts and 5 volts. That was the intended use when I bought them, but I have moved away from using variable voltage since I found what I like.

 

[stouchon]

Here is some links from digikey for some pot's.

Thumbwheel 1 turn to adjust $1.25
Digi-Key - 3352T-201LF-ND (Manufacturer - 3352T-1-201LF)

Square 12 turns to adjust $1.40
Digi-Key - 490-2974-ND (Manufacturer - PV37W201C01B00)

 

[Xariel Luis Hernandez]

Thanks that help a hole lot now I understand how it works. I was like what the hell, I thought that from zero turn it starts at 100 ohm and moves to 2 Mohm when you turn it more up....wow Such a kitty!

 

[stouchon]

You don't need to concern yourself with anything other than shape, resistance value and number of turns. The 10ohms to 2 megaohms refers to every model they have available. You can order a 0-10ohm up to a 0-2megaohm pot for that style.

You got the resistance backwards here is the chart. This chip is also rated to 5.5 volts max with a 220 ohm resistance being the lowest ohm they say to use on the chip. but you can push it to 6 volts if you want to.

Edit: How it works is you have a 220 Ohm in line resistor with a 200 ohm pot. The pot goes from 0 to 200 ohms. With the pot closed or turned to 0 resistance you have 220 ohms resistance with the inline resistor that gives you 5.5 volts. As you turn the pot adding resistance the voltage goes down. With the pot @ 100ohms resistance you get 4.3 volts. ( 220ohm resistor + 100 ohms from the pot = 320 ohms) With the pot @ 200 ohms + the 220 ohm inline resistor you have 420 ohms total = a voltage of 3.4 volts.

 

[stouchon]

Oops, it has been a while since I made mine. 200 ohm pot gets the job done anyhow, I was fairly sure of that.

Your Welcome , Xariel

Are you using the boosters in conjunction with the switching regulators?

Just trying to understand your build. The minimum output of the booster is 5v, correct? Or is your plan to adjust 5v+?

 

[Gizmo362]

I would like to throw my $.02 in to the fro, if I may. Using the table for the PTR08100W I decided I would like to drop the volts down to 2.5V just to assure that I could have a voltage adjustment that would accommodate all types of attys including the LR510 at 1.7 Ohms. I have heard that they can get pretty harsh at 3.7 volts after a while. So, I used a 500OHM pot in series with the 220 ohm minimum resistor. The result is Vape Heaven with all attys. OK....more like $.04.

Some will use both and some wont. Just for the sake of it. But mostly they where to trade stuff for and I have more then the picture shows that already moded with caps for friends.

Thats too low for me and my friends. yes i know that a 500ohm pot with 220 ohm resister is going to give you that but why you using it so low on atty wont even fire in that low voltage.

You realize off course that all the pot talk and values do not apply to the booster.

As an example a 200Ω pot would give you a range of about 5.1 - 14+V.

Read Nuck's guide for some insight.

A 200 ohm pot on the PTN04050c would give you a voltage of 14.6 to 15 volts. 5 Volts on that chip starts with a open circuit ( without using the "Trick " ) I think you figured it for a 200Kohm pot
