barry99705 Posted March 3, 2012 Posted March 3, 2012 Damn you Mr. Protocol! Again you pressed Add Reply before I could get a chance to! I'm 99% sure theres no fuse inside these alfas, so always double check any custom wiring you might be doing before plugging it in to the pineapple with a voltmeter. You can pick them up for as little as $5 at any home store (lowes/home depot/menards/fleet farm). It only takes 1ms of negative voltage to fry these little puppies. A very expensive whoopsie. telot Farm and Fleet. Man, I haven't seen one of those in years! I think I was 10 the last time! Quote
telot Posted March 3, 2012 Posted March 3, 2012 (and there is a fuse in there, right next to the big cap in front of the power port) Sweet jesus that is awesome. The commercial grade modems I use everyday (Digi International) are spec wise very similar to Alfas except they are weather hardened and shock resistant and cost $700-$1000 and they don't have any fuses. Gogo Alfa! telot Quote
Mr-Protocol Posted March 3, 2012 Posted March 3, 2012 Fuses will not stop current from going the wrong direction, it only prevents too much current. Diodes are what make one way, and may pop if you send the wrong way. Quote
Malachai Posted March 3, 2012 Posted March 3, 2012 The pineapple comes with a battery pack right? I need to check on that or buy a good one to last a while..... Other thing when will the kits come out? Quote
iamk3 Posted March 3, 2012 Posted March 3, 2012 The new MK4 Pineapple currently comes with a 5dbi antenna, retractable cat5 cable, a the new black Jasager sticker, a US AC power supply, and the quick start guide. In the future, there will be a bundle with a pelican case, battery pack, and whatever else Darren decides to include. Quote
telot Posted March 3, 2012 Posted March 3, 2012 (edited) Fuses will not stop current from going the wrong direction, it only prevents too much current. Diodes are what make one way, and may pop if you send the wrong way. I'm not referring to preventing current in the wrong direction, but protecting against hooking up positive to negative - such as if the barrel plug is mislabeled or whatever. I hook up the negative to positive and positive to negative on a 12V battery with an inline fuse - the fuse pops and no damage is done to my 12v device. I've seen it a thousand times (not by my doing mind you - customers). telot Edited March 3, 2012 by telot Quote

Gogo Alfa! telot Its a surface mount chip fuse. Looks just like a resistor or cap. But its labeled F1. You might be surprised that they do have them, just not the old school variants. Quote
Mark4FanGer Posted March 6, 2012 Posted March 6, 2012 Hi, just for my info, what happens if i use a power-supply 12V 5A (220V Input), is this possible? Or does it breaks if i use 5A output? Quote
Mr-Protocol Posted March 6, 2012 Posted March 6, 2012 I could be wrong, but you only need to watch for over voltage. Amps you need as much or more than the device needs. But buying a 5A power supply may be more pricey than the 1A it needs. Quote
