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…)

In addition to NIWeek, I have a few new projects in my queue. After a busy week and a lot of LEGO, I will be taking a (short) break to explore some new toys from Texas Instruments. Right, you will see the new Panda Board designed by Texas Instruments. The board is an open source design featuring the TI OMAP 4430 (same as in the Droid 3 and Droid Bionic). Furthermore the OMAP featured on this board has much of the RF built into the single piece of silicon. The board can run Ubuntu and Android. I plan to make a thin VM to target the board from LabVIEW (similar to LabVIEW for Arduino).

The next two boards from TI are equally awesome! First up is the smaller TI Launch Pad with Cap Touch Booster Pack. This addon contains a capacitive touch board and a new MSP430 to interface with it. It has a built in proximity sensor and is pretty cool to play with. Over the next few days I plan to experiment with it and see what ideas I come up with. The last board to join my army of embedded (soon to be robotic) projects is the Beagle Board. With a community of over 50,000 members, the Beagle packs an ARM Cortex A8 and can run several variants of Liniux. I plan to get LabIVEW working on this board as well, but what is more important is that this board integrates nicely with daughter boards, bringing the power of the Beagle to new heights. Expect to see some code in the next few days. I want to thank TI for these boards and helping me to continue my hobby. TI makes amazing digital and analog products that are great for building cheap low power projects. For example a Launch Pad costs $4.30 from the TI eStore.

And just in case you were wondering, I have a lovely bot built from the NXShield from Mindsensors.com. I plan to shoot a video this weekend and post it later next week.
