 +There is also the GL-Inet-6416a, a HW compatible clone, which offers 64MB RAM (instead of 32MB) and 16MB Flash (instead of 4MB). It also has 5 GPIOs on a PIN header and a secondary network port, available from Deal Extreme. A couple of them have been in use here for quite some time and they've performed equally - while offering more features/flexibility:

 +==== GL-Inet AR300M ====
 +
 +Gl-Inet has released a new model, the [[https://www.gl-inet.com/product/gl-ar300m/|AR300M]], which is already available with two external RP-SMA connectors. They still connect to only one radio but allow for more throughput and better overall connection stability. If you don't want to hack around and want even more RAM, CPU and storage the AR300M is the perfect choice as of early 2017. 5 of these are running through their tests here and so far they can be definitely recommended. A self deploying mesh firmware is a current work in progress but hasn't been released yet. If you're interested in getting it or help working on it, just leave a comment or join us on IRC.

 +If you're looking to build your own openwrt for the ar300m, you can use this repo:

 +In order to protect the sensor from IR/UV radiation and harsh weather, the sensor must be housed in a special housing that allows airflow but keeps the sensor safe and measurements reliable. For that purpose stevenson screens have served well in the past. A new fully 3D printable stevenson screen has been developed for that purpose:

It creates the required high voltage for the tubes and inverts the counting impulses of the tube into falling edges, captured by interrupt driven software on the sensor controller. The [[lab:pigi]] was designed in such a universal way, that it can be used for Argus as well.
