I was working on my Icom 706MKII a little while ago. I had gotten a new Heil mic for my rig earlier this summer and needed to tweak the ALC on the radio. When I was telling my brother, Tony (KD8RTT), about it, he asked me to make a video to help viewers of his channel. Check out the video above if you’re having mic issues with your Icom 706!

About 9 months ago, FATCATLAB posted a Kickstarter for an EV3 cape for the BeagleBone Black, an open source embedded Linux computer created by Texas Instruments. Their product was called the EVB. It was successfully funded and kits shipped out a few months ago. I received mine  a little while back. Generally I prefer using an EV3 brick, but I have loaned a bunch of my EV3s out to a local school district for training for FIRST LEGO League as they were awaiting their shipment of EV3s from LEGO Education.

See my thoughts (that didn’t make the video) after the break. (more…)

Panda APRSI know I have been bad at posting projects recently, but here is one I have done a few times now that is super easy to reproduce. With the super cheap embedded Linux platforms (Raspi, Beaglebone, etc.) and cheap TV dongles, it is really easy to make your own APRS iGate, just like the one in the photo above. This tutorial will give you the steps to get going with an APRS iGate. What is APRS you ask?

APRS stands for Automatic Packet Reporting System. It is a 1200 baud RF (mainly ham radio) packet system commonly used to record telemetry. Sometimes it is fun to log a trip or track a robot. APRS is a great tool for these sorts of problems. In the USA, APRS is commonly used on 144.39 MHz. It can be used between radios directly or can be used to log on the internet (via websites such as APRS.fi)  via an internet gateway or iGate.

To get started, follow me past the break.  (more…)
