New Design

Richk107 and myself have come up with another great hardware design. It will fill the gap for a needed piece of hardware left out in all Uniden scanners.

We all know our past endeavor called "Uniden homebrew remote head" was a real success and without Rich it would not be possible.

This new device will be totally open source. The schematics, The code & all the needed hardware will all be posted here. This new hardware design will cost you no more then $20-$25 depending on how your source your parts which i will also list.

Hopefully Uniden will wake up and start adding this to all of its future radios...Stay tuned

Scanner Audio Feed Probe- Arduino

Finished fixing the code. Big thank you to Richard Kot for helping me along the way.

The picture to the left is the wiring directions i whipped up. Every ethernet card is different so see what pins you have available and just change them in the INT section (RS/E/D4/D5/D6/D7) of the code.

The new code is posted below.

Dead fishy

I guess this is all the rage right now in the I.T. Security sector and Lenovo has a lot of explaining to do. Check this site just to make sure your free and clear of the evil fishy.
