Arduino powered ecig

Post by mikeunice »

Hi

I want to make a project on ecig with an arduino thats acts as a variable voltage regulator
also read and display the ohm ,wattage,voltage and amp when it is running. I know that the arduino uses PWM to control voltage signals
as it only outputs digital and not the other way around. I've already seen someone done this in youtube but my problem is im really a noob
and a beginner with arduino can someone help me? i already know how to build the e-cig mechanically with just using wicks ,wire and a battery i can already
create one but it is fixed voltage and will depend on the battery's charge.

t would help if you could give us a schematic of what you have with values needed and what and how you want to control it.

i would be using an nimh battery which is 3.7v 1100mah to power the atomizer
the atomizer is composed of the nichrome wire and silica fire wick which can be seen here in the pic the white rope is wick and the wire is the loop the surrounds it.

I prefer to use 36ga which is 27 ohms per foot. (Most factory wire is thinner 38ga.) At 27 ohms per foot, 1" of wire is 2.25ohms per inch.( 27/12=2.25)
1/2" would be 1.125 ohms (2.25/2=1.25), 1/4" would be .56 ohms (1.25/2=.56) and lastly 1/8" would be .28 ohms (.56/2=.28).
with these stuff i want to control the voltage using buttons mounted in the arduino, 3 buttons to be exact 1 for set and 2 for the +/- of the voltage
so it could go up to 6v

Hi Mikeunice,

It is pretty easy to adjust the power to the heater via PWM using an Arduino.

Measuring Volts and Amps is not much harder.
It is probably not practical to measure Ohms & Watts since they
can readily be derived from Volts & Amps.
You will also need some type of display.

My advise is to check out the Arduino tutorials.
There are tutorials on dimming an LED or controlling motor speed.
The same concept applies to heating the nichrome.
There are also tutorials on measuring voltage/current and using displays.

Check back if you run into specific problems.
Good Luck, John

Hi Mike,

Did you end up making this?

Thanks!

There is a commercial board that is used by some advanced 'Modders' as a power control unit called a DNA20D (link : http://evolvapor.com/shop.php and The data sheet http://evolvapor.com/datasheet/dna20.pdf)
This would be a great project to replicate with an Arduino!!

Anyone interested, let me know.

Iv been wanting build one for a while! Count me in. I have the following skills relative to this project.
Hardware design and manufacturer. Software and firmware development in the arduino field.

I'm also an avid smoker and sell the fluid online.

I'm eventually thinking this project could go quite far. Forget about electronic sigawett (it wouldn't allow the correct spelling...), think more in the lines of advanced intelligent medicinal drug deliver devices! Wifi networked, globally aware ;)
