Special Mod For Xmags/emags

[hitech]

Maybe someone can interpret this? http://www.solenoidcity.com/solenoid...ar/s-15-75.pdf the specs on the eMag solenoid what it needs to pull a certain weight.

The solenoid I'd suggest...

It would REQUIRE a ULT.

I actually love the battery pack. I think it unique, and adds character that most other markers lack.

Find me a lithium polymer battery that can handle a 1 AMP load from the solnoid.

Lithium Batteries are made for low current draw and will not be able to keep up with amp load required.

This is why we still see lead acid batteries in electric cars. Other battery chemistries cannot supply the burst power load electric motors require.

Ill be surprised if this can be pulled off while keeping the e-mag's shot to shot reliability.

It's my understanding that while Li Ion batteries can't handle high current draws the Li Poly batteries can. They use them for racing RC cars...

I have done this but DO NOT recommend it: Using a 9.2v version of the stock solenoid (S-15-75-24), a Morlock DIY board and an 11.1v 3 cell Li-Poly battery (1.2oz) I was able to get my Emag to fire reliably and save about 5oz. The emag's weight was down in the range of my Freestyle. The problem is safety. Damaged li-po cells can leak and potentially cause an explosive fire. Plus I have no idea what voltage/amperage compatibilities were involved. In the end I didn't think it was worth the risk, particulary with the battery in relatively close proximity to an HPA tank, but yes, I do believe that a safe alternative is possible with the right battery/solenoid combination. Hitech's idea is worth exploring someday....... :)

In muz's reply he mentioned the ULT would not return the sol plunger. what if you used the second output in reverse polarity to return the plunger ...

[Rudz]

maybe

how about just a smaller battery in the same pack? the battery is pretty heavy, the pack isnt all that heavy, though mine is the cnc xmag style im sure a lighter battery would be really helpful, but its not all big of a problem, it makes the emags and xmags stand out...

Are you trying to steal my ideas?!? Almost all solenoids are built such that reversing the current won't change the direction they work. If someone could get a custom solenoid that was basically two solenoids in one; one a pull and the other a push...

Of course, it would require a modification to the board and new programming, but I think the eMag board has open ports...

I beleive there are push pull solenoids.

This was just to say they exist. Dont know if they would work, but there has to be something out there.

I saw push and I saw pull. I didn't see any push and pull in the same solenoid...

If you can find and I'd be interested...

Kyle-
long time, eh bro? hows the better half doin?

regarding pushing the noid back out with reverse current, it can be done, but only with a very special type of solenoid, a "latching" noid.. more $$ and not as easy as you might think to work with.
Would also burn more juice for every shot. :-/


In my eyes a proprly tuned Hyperframe/Devilmag + ULT is an extreamly nice Electro-mag type setup.

out!

Li-Po Amperage ratings

Towards the middle of the page...

My R/C Heli Draws 8-9 amps...

[M.Don]

just for clarification this is not a battery mod, also im not sure what he said about the noid, but i think he said he was removing it, i dont know if its being replaced with another noid or some other item, but i'll keep you guys posted. as for lipos, i run RC boat which have a much higher drain than cars or heli's etc and i know lipo can push 60amps constant so that not an issue, the charging and explosive nature is much more problematic. however within the next 12months theres going to be a big jump in battery technology. on the subject of the battery pack, i like them and even if i didnt need mine, id proberly keep it on, and just remove the battery.

Unless something's changed recently, electric R/C cars use NiCad or NiMh battery packs.
