On/Off Switch for Emag/MicroE

[cphilip]

the problem with this Mod and why Tom doesn't do it now on them is there was no small switch that Tom felt was realiable enough to handle the voltage. And if it fails your Emag is down. So he doesn't use the switch as the interupt is more reliable. The ACE board happens to have a place where voltage is reduced for a path allowing a small switch to be put in line so it became an option for that. But that does not occur in a Emag without ACE.

Now that being said I was suprised to see Kayle say he is working on one. That must mean he has found something to do the job? If he has then I would feel confident with what he might have found to do. I suggest you wait and see what he has up his sleave. If he is doing it you can be confident its well researched by someone who knows that system about as good as anyone.

Tell us more Kayle!

I did some talking with the large elves that designs alot of stuff at AGD. He helped me with making a switch setup like the ACE board without the ACE >standby..

So what you invision is a little mini board with switch that steps the voltage down and passes through a switch and then steps it up again?

And if you could mount this even in the existing hole itself then you would be "Da Bomb"! :)

You wouldnt be able to mount it in the existing hole, bacause the battery still has to be charged. The swith would get in the way of the charger. Now if he could make a plug in charger at the same time, then he would definitly be 'da bomb'

i thought the x-mag switch was just used to switch a transitor which in turn turns the actual power on. The lower voltage from the ACE board would just be used as the signal (logic level, 5V).

if you could rig the switch on a 5V regulator and use that as a signal for a transitor, your golden.

[cphilip]

Well it might could be it's just a matter of clearance is all. The power from the charger does not flow through the hole. It just makes contact with the two battery spring clips but still it would be difficult mounting it there and also clear the charger plug housings. I suspect he is indeed talking over on the board or something.

I often wanted to look around for a small plastic plug for that hole though. I was thinking a small automotive push pin trim plug would do it.

Sniper is on the right track , still waiting on part confirmation..

You should be able to just get a 5amp power transistor, wire the base to a switch and the other end of the switch to ground. Wire the emitter to the battery and the collector to the marker and you have an on/off switch.

switch

What's that mean in "I don't know crap about electronics" speak?


I'm looking for someone else to do the mod for me - you should see the mess I made of my WarpFeed!

If you get a power transistor from Radio Shack it should have a diagram on the back. Hopefully it will look like the one here (it may have a circle around it). If you wire the top two backwards it will simply not power on the emag. Everything needs to be soldered.

Good luck.

I'm lost again.

why would you want to use transistor, when a simple inline toggle switch would work best? 1/4" toggles are rated at 5amp at 120v. Since I use millout body rail, I could put the switch on the rail, and possibly the power out for the revvy as well.(If I want to power the revvy off the emag main battery) Only reason Ihave not done one, si aesthetics. Frankly, the switch should have been part of the control board. have one of the button sequency to power up. transistor/fet or solid state relay could have been put on the board.

[WARPED1]

Wouldn't an on/off get rid of the wonderful Hybrid mode? Wouldn't you have to make some kinda 3way toggle switch?

[hitech]

The micro-mini toggle switch at Radio Shack is rated at 3 amps. Since the solenoid can draw 3 amps, that's pushing it. Come to think of it, a 5 amp transistor is probably on the small side.

And no, it wouldn't affect hybrid mode at all. It would be the same as the pin. Pin in is the same as switch off. Pin out is the same as switch on.

[WARPED1]

So, you'd turn switch on to get hybrid?(frame switch ot "M"), and to "E" for that mode? I get it!
