Ammo Can go kit

OK, I've just finished putting together my ammo can go kit. I will be using a cheap android phone to serve as a terminal, camera, and/or phone extension, as needed. It's got a battery built in, a power switch on the outside, a very small node (AR-150-ext), an AR-MT300N to act as a wifi client, 5V, 24V and 48V power supplies, and a slightly modified POE switch to provide both 24V and 48V ports. The battery is a 7AH gel cell, with 1/4in tabs. It fits perfectly on end inside the plastic ammo can. The plastic was also easy to cut a slot out of for cables to come out as needed.

I've got a set of nodes already mounted to a short PVC pipe that will screw on the end of a painters pole to use as a more high profile and higher power node. The antenna on the outside is connected to the AR-150. I've got another switch on order to modify for at home if someone wants to see how I modified it when I get it in (I forgot to take pictures, and don't want to take the box back apart). The ports are color coded with the NW Ohio AREDN-Mesh standard (Though I need to get a better yellow). 

To keep things compact, the ethernet cables used inside the box are the 6in micro slim run ethernet cables from Monoprice. These are great for non-powered runs, and readily handle a much tighter bend radius. 

The white wires hanging out the side will go to a set of powerpoles to charge the battery, or power the unit when other power is available.

Color Code?

I have done a bit of searching but have failed to find a reference to the color code that you mentioned in your post.  could your point the way to a link?

BTW  great job on the go kit!

It's the same code as Mark

It's the same code as Mark used in his.

Red = 48V
Yellow = 24V
Green = no POE

Elsewhere locally, we also have Blue = Switched 24V for a physical installation where we want to be able to turn an access point on/off. I would have swapped the green and blue, if we hadn't already had the green established when preparing for that install. I'd propose purple for switched 48v if we desired that somewhere.

That's cool! I set up

That's cool! I set up something similar using a plastic, waterproof enclosure. It has the AR300M16-EXT version of the GL iNet router - the one with 2 external antennas. It's connected to a rubber duck and an amplifier, which is then connected to a 2.4 GHz yagi. It's powered by a combination 12V/5V juice pack, which is charged by way a small solar panel. 

I tested this for several days and it looks like it should be able to run for an extended period of time without issue.
The enclosure:

There are multiple yagi's out there with different cord options.

Here's the combination 5V/12V power supply. It comes with a splitter to charge and power an external device at the same time.

Here's the solar panel

The amp needs 12V, the router needs 5V.
Here's a link to the amplifier

Here's a link to the router, but Amazon is out of stock. I ordered it directly from GL iNet

Has anyone tested these amps to see if they work in the mesh environment?


Very cool.  How long do they

Very cool.  How long do they last on battery?  I have a few gl-inet AP's I want to use on Field Day.

It depends on the exact

It depends on the exact configuration I have deployed going off of this. If it's just the GL-Inet units, I see about 8H on the 7AH battery. If I put a more powerful node up on one of the 24V ports, as well as an IP camera, I see about 4H runtime or so.
