If any of the info on this website was useful for your projects or made your head spin with creative ideas, and you would like to share a token of your appreciation- a donation would be massively appreciated!

Your donation will go to my Robotics Fund, straight towards more sensors, actuators, books, and journeys. It takes a lot to continue building these robots, and I’m really thankful of everyone who helps encourage me along the way.

Dogcow + iPad

IMG_1734 - Version 2

Dogcow now works with the iPad without the use for a middleman in between! It goes straight from the App to the XBee for Dogcow to receive.

Here is a video explanation:

Or view the video on YouTube.

The process begins with an App using the ExternalAccessory framework:

Then goes through the SkyWire cable:

RS232 is converted to TTL:

Which is then sent through the XBee:

The XBee is powered by 3.3V, using an Arduino as a simple power supply haha:

And Dogcow receives with the XBee:

Making this whole process really cool!

Here are some resources that may be helpful:

Also, as per Technote #31:

Dogcows, by their nature, are not all dog, nor are they all cow, but they are a special genetic hybrid. They are rarely seen in the wild. Since dogcows are two dimensional, they will stand facing a viewer “on edge” to avoid being seen.

    I never thought about using the Diecimila 3.3V supply to power an Xbee, I suppose it does put out 50mA, which is (just) enough to power one. Did you have to use any power buffering capacitors besides the ones already present on the XBee adapter? (ala the huge capacitors on the the Tweet-A-Watt)
