1) Trackingbox case: – Dimensions: 310x240x110mm (approx.) – Sealing: IP55 (or above) (A) ABB box However it may be hard to find from some locations. You have to drill your own holes anyway so you can prefer a box without pre-drilled side holes! Ideally you are looking for these MPN: 1SL0828A00(*) / with pre-drilled wholes 1SL0858A00(*)
Dealing with grounding and lightning protection is obligatory when setting up a roof antenna. Bad grounding might cause not only damage to your antenna and equipment but even your complete home electronics or ignite fire. Lightning is dangerous for two reasons. Direct lightning conduction can cause impulse voltages of higher than 20 Megavolts, whileas induced
There are one million awesome things you can do with small router and an OpenWRT firmware on it. I have been surprised how mature, easy to use and community driven it has become. The WR703N is an awsome device and I have probably never seen such a small device (smaller than a smartphone) with so
This page is a work in progress and will be updated on the way. Last update: 2015-03-04 The prices included are the prices I found for which you can buy these components new. Many of those parts are well known in the hacking world and you often find them overpriced, therefore you can take these
The project uses many well established hacks and combines them in a very clever way, without needing to re-invent the wheel. Software Defined Radio for instance using an inexpensive DVB-T receiver hack allows to receive radio communications with a very wide bandwidth for just around 20$. The usage of a small router TL-WR703N, which has been
As part of the engineering tools series we will introduce several tools which make working in teams on projects, especially distributed open-source projects possible. Read more about how to learn how to use Git and some hands-on beginners advice.
