New Protege Button Idea - Please Steal Me.

[them0nk]

I thought this would be a good new thread... to get more input.

Out of the other thread here is my idea on a chinese button replacement for the protege. As in swap-out-able part.

Casey & Steve, if you guys like it, i'll shoot you the designs. All i'd ask for is one completed... and if you REALLY like it, a prodigy v2 (haha i wish)



the gray is supposed to be plastic. there is 1 part missing from this, a 2 piece button, the contact disk, and a plastic piece that would mate with the current protege button

top view:



what do you guys think about that idea? i saw somewhere you guys like new ideas... here is a new one... to take away all the solder.

i mean this concept can be used by anyone... just throw me a bone if you have a heart.

edit: maybe PS could create a protege v2 with a thicker tube & better end cap threads + the button idea... would make for a kick ass indestructible 14500 mod.

Schweet. the now plastic button could have a small brass *nail like* insert to make the connection.

Nice drawing Monk. I was going to try and draw something like this at work yesterday but the work load is rather high right now. I think they'd frown on that. LOL

Here's another quickie. Instead of a resisitor you could use different metals for the button insert that would have higher or lower resistance thereby changing the output voltage without a lot of heat buildup. When you wanted to vape at a different voltage you'd simply change your button.

*Gotta get CAD on the home machine*

Again, Nice detail man....

Monk ... Great Idea bud ...

Today at the shop we were brainstorming and came up with a way, much like yours, except the brass contact posts were (V'ed) and we were using a disk/snap spring Difference of materials would be super important so they wouldn't arch/weld themselves together. We were thinking Brass and Aluminum ... Both are great conducters

O ... we would take care of ya mOnk if we end up using something like this

O, and Brock ... We tried different materials for the contact posts ... The highest voltage drop we saw was using A-1 Steel and it was roughly .25v under load ... Not much.

The MOST conductive (even higher than brass) was Aluminum and Copper

Have to run out to grab food with the wife. be back on a bit later to discuss further

My hubby don't go out and grab food for me. :-(

I'm not talking about simple metals like brass and copper.

There's always Monel, Hastelloy, etc. Think Alloy...

Here's a small list of the conductivity of various metals

Aluminum 59
Brass 28
Cadmium 19
Chromium 55
Cobalt 16.3
Constantin 3.24
Copper:
Hard drawn 89.5
Annealed 100
Gold 65
Iron:
Pure 17.7
Cast 2-12
Wrought 11.4
Lead 7
Manganin 3.7
Mercury 1.66
Molybdenum 33.2
Nichrome 1.45
Nickel 12-16
Nickel silver 5.3(18&#37
Phosphor bronze 36
Platinum 15
Silver 106
Steel 3-15
Tin 13
Titanium 5
Tungsten 28.9
Zinc 28.2

I vote for Molybdenum and Constantin.

Use the same ID (inside diameter) so I can purchase the switch set up for my current Protege!

Me, I choose Zirconium.

was my entire idea :-P

and actually... some of these parts would be a BRAT to make... here is the finished drawing blown up the best i could get it to look:



the TINY tapped hole is a 0-72... wtf i've never even USED one of those in 3 years of machining (then again 6-32's were as far as we'd go)... there is probably an easier way to have the button not ground out on something when you pushed it in...

i'm really happy that people are responding well to this!!!!!

Oh and good point about the welding thing... i wonder how long it would take brass/copper fittings like that to weld to each other though... which would ALMOST be funny haha...

Graphite has a huge voltage drop i thought... and why would someone want to drop the 3.7v on the protege :-P (i know i know the material voltage drop would be for the big brother prodigy^2 <---steal that too! hahaha)

edit: i know a guy that worked at, and might have gone back to work for a MICRO part manufacturing company called Sorensen Engineering... they make little tiny freaking contacts for computers and such...

I notice your spring is positioned between the two contacts, could this cause a short if it tipped to the side?

You could use a polyurethane cylinder as a spring, maybe about 60A durometer, it's not conductive. They use this material for punch press strippers. Make it a hollow cylinder with a close fit in its recess, and if you need to remove it, just thread a screw into the hole to pull it out.
Acrotech, Inc. manufactures standard and custom K-Prene&#174;urethane products

The flats on two contacts need to be precisely aligned in order to make a good connection with the disc. Maybe you could press them in as rounds and then spot face with an end mill, to get the faces exactly in the same plane.
