I just finished my first watch app for the Pebble Smartwatch. It keeps track of the score during a table tennis match. It’s still in beta stage so I’m glad when I get feedback.
You can find the details and the downloads on this page.
I now have an interesting idea what I could use the LaunchPad for. I don’t want to tell too much about it yet, but I ordered a GameBoy camera I want to connect to it, so now I need to take a look on how to program it.
As an early Christmas gift this page can now be followed on Facebook.
New Stuff: Two Stellaris LM4F120 LaunchPads by Texas Instruments arrived today.
So, the prototype is working. Not very beautiful, and the soldering sucks, but it works and it spares me from putting a breadboard in the boat again. Below the circuit board is the Arduino Mega which is currently operating as the test platform, on top of it are the MRF24J40MA wireless module and the Adafruit Ultimate GPS receiver.
Now I only have to build something similar for the bluetooth bridge, make some adjustments to the software and I’m good to run another life test on a lake (without having to fear that the boat wanders out of bluetooth range).
So, I got my wireless bridge working. Here are pictures of my setup, an Adafruit Ultimate GPS module happily sending its location to my Android phone.
The Arduino sitting out of my window on the roof is connected to the GPS receiver and one of the two MRF24J40MA modules. Continue reading MRF24J40 Bluetooth Bridge
So, after some trial and error I managed to interface the MRF24J40 modules with two Arduinos and have them exchange data.
This looks more complicated than it is. Continue reading MRF24J40 and Arduino
In the last couple of weeks some interesting new toys I ordered arrived. First, two MRF24J40MA wireless transceivers. I actually had them lying around for a while now, but I wanted to wait until the GPS receiver arrived as well before I start playing with them.
