Electronic Autococker 3-Way

[big E kingpin]

my very own E M CUBED e-cocker

i work for a firealarm company, and one day i was working on a bell circut, and noticed that the bell worked off a magnito/silonoid type thing, so i stole one. got home and took a dremal to the plastic cocker trigger frame i had, and packed that sucker in there. the only draw back is the 3 9volt batteries it takes to fire it. the trigger is a micro switch i robbed out of a pullstation. the only part i actually had to buy was the mac valve. it works, its not the prettiest thing nor is it reliable at all, but someone said i couldnt make one nevermind make one out of parts i stole from the job.
whos laughing now
hahahaha

solenoids and e-cockers

solenoids are an item that there's not a whole lot of info on for the average person to find and read. you have to do some diggin' and do some research.

there are several solenoids available to use for direct actuation of a cocker sear. the trick is to find one that will do the job that is as small, and effecient as possible. in other words uses the least amount of current as possible. voltage is another consideration. because you don't have a portable high voltage source, you need to find a solenoid rated for a voltage that will work with your power source.

solenoids are rated in duty cycles. a solenoid rated a 10 volts, 20 watts, continuos duty(100% duty) means that if you give it 10 volts, you can leave it energized indefinitely and it will not overheat and lose power. the same solenoid given 20 volts, can only be energized for 25% of the time. a 25%duty cycle. in other words for evey one second it's energized, it has to be off for 3 seconds after that. now giving it 40 volts(4 times the nominal voltage of 10 volts) would give you a 6% duty cycle.

now the stroke of a solenoid effects it's power also. the longer the stroke the less power it has. this is true for both push and pull type solenoids. I beleive the e-blade uses a push type solenoid to push up on the front tip of the sear. and the race gun seems to use a push type to push a roller pin out of the way to let the sear fall. the design I use is a simple pull type solenoid that pulls the back of the sear directly down. it is a very simple and effective design.

so to make your own solenoid actuated sear you need to know how much force it takes to pull the sear out of the way of the hammer lug.
the shortest stroke to pull it out of the way and work reliably.
the shortest possible duty cycle that does not require overly high voltage.
and last but not least the voltage that will be used at this duty cycle and be low enough to be compatible with a 9 volt or other battery voltage available.

hopefully some of this info will help anyone who is interested in building their own direct solenoid actuated sear E-cocker.

you could make your own gun usin a timmy solenoid....79 bucks at paintballkingdom.com

The solenoids on the Eclipse E-Blade are manufactured by SMC, and i'd wager very similar(if not the same series) as a version used on the Race frame. The Race frame has had a couple different solenoid types available, but I believe they are all made by SMC. Angel LCDs also use an SMC solenoid, which are SYJ Series 5-way valves I believe.

So is there any sort of materials list, and step by step guide to do this with? Im gonna build a cocker, and something like this would be uber fun.

ups

Up for a hell of an idea.

the electrician: you know your stuff man, info on all the different ways solenoids are used in the various cocker frames would be nice. Also, an exact list of the precise diagnostics of solenoids that can be used would be sweet. Do we need two to activate all parts of a cocker? Do we still need a board like an LED frame?

bryan- how would we do that exactly? not discounting the idea, just interested.

Vegeta- stop being a jerk, you're just acting like a loser. you don't like autocockers? (edited because it read as something else) then fine. then this thread has no use for you so stay out of the thread. This isn't just about making a cheap frame, it's fun creating our own stuff. You don't like the creativity, then piss off.

Keep it up guys, I am impressed and very interested.
