R2 Touch vs Beacon 73

This is a remote control app for members of the R2 Builders Club. Apart from looking pretty, and playing sounds (if you upload them to the application), it doesn't do anything unless you are building an R2-D2 replica robot and have MarcDuino receiver boards (as described in www.marcduino.com and on my build log on Astromech.net). If you do, lucky you, it will allow you to control the dome panels, holoprojectors, sounds and dome lighting of your Droid in all sorts of interesting ways. You can see a demo of how it works with my R2 here: http://www.youtube.com/watch?v=AUod3LRQ1DI The app can run all the way down to iOS 8 on an iPhone 4S. The app doesn't include any sounds by default. If you want sounds to play directly from the app or through Bluetooth, you must upload your own sounds files to the App using iTunes. The sound files are typically the exact same you'd use in your remote sound system of the robot such as my MP3Trigger setup (described on www.marcduino.com). Commands, in the form of programmable short ASCII strings, are sent via the internal WiFi iPhone radio to a remote WiFly receiver. Alternately, the app also generates a 9600 baud serial output stream on the earphone audio port. This way you can send serial command to an external XBee transmitter radio for a more reliable link. You'll need a small level adapter board to use the audio serial capability, also on www.curiousmarc.com. Since you can customize most buttons and commands, you could also use this as a generic remote control app to send any short serial string via WiFi (to a WiFly radio fore example) or serial link (through an XBee). And with a spiffy R2-D2 inspired interface to boot!

Beacon 73 makes sending your APRS position simple. Just open the app and start. SIMPLE BEACONING • Start or stop auto-beaconing from a clear, focused dashboard • Send your position immediately whenever you choose • See when your last beacon was sent and when the next one is due SMART TIMING Choose manual, timed, or movement-aware Smart beaconing. Beacon 73 can adapt beacon timing to your speed and direction. MAP AND TRACK • See nearby APRS station callsigns, icons, and status • View your current position and recent location track • Use a map to see other stations in real-time TRY IT SAFELY Demo Mode uses simulated data, does not request your location, and cannot transmit. Explore the app before entering your callsign. Beacon 73 connects to APRS-IS. Live operation requires a valid amateur radio callsign and APRS-IS passcode. Beacon 73 is not an emergency or safety service.
