Variable power touch switch on my precious

[caesar]

Hi fellow modders and vapers!

Still in testing stage for now but I want to present you an early prototype of my latest variable power touch switch.

Showing it by vaping is difficult so I used a LED in the video to demonstrate its capabilities.


Basically it senses if you barely touch it or push it a little.
Power varies with the touch surface / how hard you push.
To completely power an atty it takes 1/30 the effort needed to push a manual battery button. This is a touch switch after all

It takes less effort than any button to fully power an atomizer but with a soft touch you can vary the power.

This allows me to fully power it for 2 secs then slowly decrease the power to atty keeping vapor production but decreasing battery consumption, prolonging battery and atomizer life (no more gunk buildup as it seems - more testing needed still).

Starring in this video:
Mega 510, red LED and my precioussss that just got upgraded with this test version of the button (and changed 901 connector for a recessed 510 because of the space left free inside).

Remember, still testing, not final. Also nothing for sale!

That is awesome!

Like a switch on a cordless drill...cool. Isn't that like a carbon pile rheostat of some sort?

 

[bigozone]

that is cool....

i just want to know if it is a SOLID STATE solution??

 

[BuzzKill]

Very nice !! can you throw a voltmeter across it and show us the actual voltage variation ? , or in a real setup use an atty and a current meter and volt meter .

 

[radwor]

Nice, so it's a 2 sec.timed full power and then drops?

 

[beast775]

very good idea,i like the high to low it would get very easy to work.i would like to see a meter in series on the switch.that would be awesome

 

[ZorbaTheGreek]

Awesome idea and great work. The modding community on this site never ceases to amaze me.

That's exactly the idea, only this one needs less effort.

As solid as the bronze metal cap.

Will do as soon as I can grab a real camera to film with.

You vary it yourself to your liking. Actually it takes some time to get used to, but worst case scenario: you always activate it at maximum.

Cool Caesar , waiting to see the results , Nice job if it is purely mechanical ! we'll have to see how the life cycle tests go ! and repeatability.

Ya I know sorry

 

[j0ker]

caesar you have amazed me once again! I always look forward to seeing your latest ventures!

 

[caesar]

Thanks j0ker! This one has some potential indeed.
Every hour that passes I'm getting better at firing the atty the way I want it.
It's like learning to drive a car

It not mechanical at all, no moving parts. Just some fancy electronics.
The parts are well oversized, the control MOSFET is good for 18Amps continuous drain current! No problems in time with these.

I have an adjustable voltage regulator from RS, LM317T. Could this be used for something like that or does it serve some other purpose? I grabbed it by accident one day and have no clue about the adjustable part of it.
I would like to find a circuit that could run two different resistance coils at different voltages with the same power supply...like a pre-heat, heat type setup.

 

[caesar]

You could use it together with a camera shutter button (it has 2 positions)... it's not a bad idea.

 

[nicotime]

Hey your good...I just got done tearing apart my busted 35mm to see if it would have some modding parts. It did have a 3.7 Lion in it too.
Thanks C

How's the vape at 18A?

 

[caesar]

It's like on a very good fully charged battery only for longer.

The atty still consumes 1,8A (Joye510) only the MOSFET (digital switch) is rated 18A, that translates to almost non existent internal resistance and no chance of failure in the near future.

 

[nicotime]

C...how many amps you think the camera button would be rated at? It looks like a regular tact switch to me. There are a few of the flexible metal dome buttons built in to the ic circuit film too that look pretty durable, but would be hard to make them function by themselves. I did get some good spring metal battery connectors out of it.

 

[BuzzKill]

Nico there are variable voltage regulators out there with external control ( uses a low current switch that way ) the variable part is just a matter of resistors to SET the voltage , or a variable resistor to control it .

 

[nicotime]

So you vary the voltage to the control pin to vary the overall output of the regulator?
