Electric trigger whithout any moving parts

[DanMan]

I had a great idea the other day when i was playing aroung with one of thoes balls that light up and make a noise when you touch two strips of metal on the outside connecting the circut with your finger. Anyways, I was thinking could you rig up an electric trigger with a contact strip as the trigger and have another on the grip frame to complete the circut. There would be no moving parts so it would be the lightest trigger humanly possible!! The only problem would be saftey and keeping contact on another part ot the hand. Do you guys follow what I am talking about?

It sounds like there would still have to be movement for the contact on the trigger to touch the contact on the frame. Even if you put a contact on a glove to connect to the frame, there would still be movement, and then, why not just have a trigger?

Have you seen the clock run off a potato? In the same way no metal touches, the current flows through your skin. only your bare fingers move. I will try to get a pic and it will be alot clearer.

How about the way some lights for your house turn off/on or dim when you touch them. The same technology could be harnessed if you wanted to.

you have the idea

Ah, I see.

I thought the contact on the grip frame would be behind the trigger and the trigger would have to move anyway.

With the electrical conductivity of human skin being what it is, you would probably need the contact points close together. Then, if paintball fill has a low resistance and the gun gets hit, lookout. Or if your hand sweats enough to keep the contact bridged.

I'm sure one of the threads in drg's post above addresses this, but I don't think it would any faster. Heck, I think it would be slower. Drum your fingers on a flat table in a "walking" fashion. You can only get a decent speed, right? Now, if you have one handy, walk a good e-trigger (if not, hold a pen lightly by the end. This should feel similar to an e-trigger). The trigger bounces back, engaging your finger quicker, allowing you greater walking speeds. That's why there's so much emphasis on a good trigger. They can actually increase your BPS in semi.

i know exactly what your talking about. i had accually thought of this about 6 months ago, and even built up a small circuit on a breadboard.

i searched around and found some diagrams on how a touch lamp worked. a very small voltage is constantly on the gripframe of the gun and you complete the circuit by touching the trigger pad(not a conventional trigger). the problem i had with this one was speed. i couldnt get it to read my fingers faster then 3 or 4 "switches" per second. i think it came down to needing more voltage to compensate for our bodies resistance levels. i didnt have a variable source to work with either. back in college i could have tested this out with more equipment and teachers to help me troubleshoot it.
im pretty sure i could dig up those diagrams again if someone is in any electrical engineering courses, or has the supplies to work on this stuff
