TVShow S02E13X56 Arduino Beatdet
This 4 channel Arduino Beatdet (bidet) rocks your spots off. Select a beat on your phone and the Beatdet will jam out while it cleans you out. The Pirate Radio Bellagio of bidets. Authentic streaming music. Beatdet Pro allows you to choose any track on your phone to wipe with.



Notable thanks to MakerBar in Hoboken, New Jersey

It should be noted that this, as are most of our projects, a prototype, and surely demands several refinements; for example, superior nozzles for a more effective spray.

MakerBar Sign
The while awaiting for the 3D printer to complete the 1 hour and 15 minute run on a series of minute nozzles for another developing project, I had decided in my final days with in the MakerBar space to create a much needed front door sign utilizing the dreaded LEDs I have come to both despise and support...because ooh and ahh. CNC MDF RGB OMG Sigh.

MakerFaire MakerBar Arduino Candy Box
Last (last-last) minute build for the MakerBar booth at NYC MakerFaire. Swipe for candy, the closer your hand, the angrier the box becomes (vibration) then proceeds to open, revealing an unexpected robot arm (false-bottom) that presents you a with piece of candy. All materials were constructed from MDF by way of CNC.



Notation
Limited time did not permit me to complete the build. A reloading system was to be applied to the under side; it was alternatively reloaded by hand as the effect was slow regardless.

TVShow S02E12X55 Arduino Water Boarding
A lie is the sin man tells in fear. To seek the truth, we must aide the sinner in crossing a threshold to find deliverance. Problem is, I am binge watching Ally McBeal Season 4, so allow us to automate the process. Attach sensors to said victim...er...suspect and allow our computer (Jacob) and an Arduino Uno to decipher if they are telling the truth or require some, inspiration.


A notation; the quality of this video is sub-par because I often shoot on poverty driven video equipment, namely an elderly Droid Razr. Forgive the potato.
