Been over a month

Sorry been over a month since my last post, it will be worth it. Im working on a hush, hush project. It is still in the prototype stage but been working hard and in collaboration with our Drafting Department and Precision Metal Technology, with the all important 3-D printer.

Hint: it's striped Arduino with an L298 H Bridge and QRD1114


The first 5, various stages of the build for the five prototypes, preproduction run.

Very excited about this project, it been too long sine I've done a collaboration with others. Software is almost done thanks to Vin. Will post formally once all bugs are out and in the final revision (so far we are on version 5 with three variations).

Echolink Over Radio Demo

How to access Echolink over RF on a local repeater

From Wikipedia, the free encyclopedia:

EchoLink is a computer-based Amateur Radio system distributed free of charge that allows radio amateurs to communicate with other amateur radio operators using Voice over IP (VoIP) technology on the Internet for at least part of the path between them. It was designed by Jonathan Taylor, a radio amateur with callsign K1RFD.

The system allows reliable worldwide connections to be made between radio amateurs, greatly enhancing Amateur Radio's communications capabilities. In essence it is the same as other VoIP applications (such as Skype), but with the unique addition of the ability to link to an amateur radio station's transceiver. Thus any low-power handheld amateur radio transceiver which can contact a local Echolink node (A node is an active Echolink station with a transceiver attached) can then use the Internet connection of that station to send their transmission via VOIP to any other active Echolink node, world-wide. No special hardware or software is required to relay a transmission via an Echolink node.
