Drunkrina Code

So it has been a bit more than a day since I planned to put up the Drunkrina code, but with Maker Faire on the horizon I used that to push myself to getting updates to this site and rise above other activities in life. So here it is.

Wooduino Available at Maker Shed!

Wooduino's are now available at the Maker Shed so go check them out there, too!

Availible now! And Maker Faire Report

You can now purchase the Wooduino on Etsy by following this link!  The Maker Shed may also soon have the Wooduino online (it was availible in the Maker Shed at the Maker Faire) and I'll link to it also if it becomes availible.

I had a exciting time at the Maker Faire getting to talk with a lot of people and hearing about their great idea for Arduino projects!  There was a constant stream of people through the booth (and I thought I might get bored at the booth, HA) and though many it was the first time they heard the word "Arduino" the rest I got a very positive response since they knew how useful a stable, easy to modify platform could be for making projects.  I have many ideas of new Wooduino projects people can make to be posted in the coming weeks!

Drunkrina = Drinking + Ocarina

The Drunkrina is a Arduino based ocarina build on the Wooduino platform.  But this instrument has a twist, you must be drunk to play it.  Using a alcohol sensor as the trigger for the notes requires the musicain to have had a least one drink before playing.

I'll get the source code up tomorrow night.

Make Talk!

Wooduino was discussed on Make Talk episode 11! I called in to tell people about the Makers at Maker Faire site and the hosts were great and talked a bit about the Wooduino. The Wooduino will be available at the Maker Store at the faire!

Wooduino Overload!

For even more Wooduino pictures head over to my Picasa albums Wooduino Deluxe Pictures and Wooduino Standard Pictures and remember to look for Wooduino at the Maker Faire, May 30 and 31st!

Wii Knock or Cheap Arduino Bluetooth

This use of the Wooduino has a Wiimote attached to the board with some screw and Vex parts, along with a piezo buzzer being used as a knock sensor. When the Arduino gets a knock reading from the piezo it uses a servo to press the A button on the Wiimote. If you only need one bit of information it could be a cheap bluetooth connection for the Arduino. Or if I can get a microphone connected to the Arduino an easy way to use the Wii Fit without holding the controller.
