What it is:
The MegaTap 3000 is a pair of gloves that magnify the action of tapping your fingers into drum sounds.
How it Works:
Below is an image of how the whole system connects together. The basics is that we have a central control boxâ€¨ which looks at the forces exerted on FSRs in the gloves. This information is transformed into MIDI signals sent â€¨to a synthesizer which creates the drum sounds. Serial information is also sent to a computer to help visualize the act of tapping.
Below is an image of the circuitry, with the gray line indicating what is inside the control box. We use a multiplexer â€¨to route the analog sensor data from FSRs since the 18F252 PIC chip has only 8 analog inputs.â€¨The code which the PIC chip runs is here.â€¨There is an extensive working site that documents all our sequences of code here.â€¨â€¨There are two computer programs written to work with the glove using processing. One is a simple visualization.â€¨ This program (which needs to be hooked up to our box to run) visualizes out play and menu modes. â€¨The other program is a game that challenges two people (each wearing a glove) to tap faster than each other.
How it is Built:
Below are photographs of the system. The first simply shows everything hooked up.â€¨The second is a picture of the inside of the control box and how it is wired. Note that we are using a 9 volt battery.â€¨Â The last picture shows how we make the connection from the gloves to the control box. The box and the glove both have female Ethernet jacks on them. We use a retractable Ethernet cable to connect the two since the cord is very light-weightâ€¨(normal Ethernet cables are too stiff and heavy), and it stores easily.
MegaTap was exhibited at the 2005 ITP Fall Show and the Sony Wonder Lab.
