So over the last week we have made some great progress on our Beat Box. We got the wooden top purchased from a lumber yard in Woodstock, NY, you can see my buddy Chris in the above photo cutting this gorgeous piece of Mahogany down to size for me. As for the size of the box I am going back and forth between having everything wooden or using plexi to reveal the technical side of the piece. I really like the idea of having a nice natural piece of wood for the lid and having the technological side revealed below it for contrast, but I can also see the reason for keeping all that hidden and more of a mystery.
For our physical computing media controller project Inessah, Amik and I decided to create a confetti machine where the user can control the height of the confetti by raising and lowering their hand. We first tried using a DC computer fan with a ultra sonic sensor which worked perfectly for controlling the speed of the fan based on the distance of your hand but it soon became clear that a 12 volt computer fan wasn’t at all powerful enough to blow a large amount of confetti more than about a foot.
So this week for our lab in P Comp we are having fun with knobs and laptops, aka potentiometers and controlling Processing through the arduino. Below is an image of the arduino with the potentiometer connected to it and below that there are two videos that were created while I was controlling Processing with the potentiometer. Click and watch the purdy colors.
So for our Intro to Physical Computing class we learned how to make simple tones and notes using just the arduino. I attached three pressure sensors to communicate with my laptop and output a note to the attached speaker. To make things a little more interesting I decided to play a song. Rather than choosing something like Old McDonalds or Happy Birthday, I opted to choose something a little more current. So below is a video of me playing along to Snow Patrols Chasing Cars. Im not a huge personal fan or anything, but hey its only three chords and crazy easy to play. Enjoy Snow Arduino, haha, god Im such a nerd.
This is a test using servo motors and the arduino. A pressure sensor is hooked up to a servo motor which is attached to a finger board. When the pressure sensor is pushed the servo motor acts as a leg (or finger) and scoots the board across my dining room table. Ok so it only goes about 6 or 7 inches but its not the distance it goes its how well it works, ha. Video below.
After days of trying to figure out why the final product wasnt working but the test had no issues, I finally completed the final project and mounted it to my door. Now everyone who comes to visit me will know just how big a nerd I am (and probably not come back, ha). Enjoy the video below.
Here is a test for my NerdBell Stupid Pet Trick project. When the pressure sensor is pressed the arduino activates a hacked audio birthday card that plays the theme song to Star Wars.
