Presentation Day Video

Presentation Day Video! 

Video...no sound

Here is the video we originally took. I didn't realize none of the sounds we were producing wasn't getting recorded. We need better speakers. The sounds you are hearing is just ambient noise. I'll try to get a better video up tomorrow.


Where's the sound? 

Final!

It works!

We had a few bumps, but have a good working prototype.

We have our circuit, which looks like the MIDI setup from before but with a connection for the photocell. The circuit is housed in a protective box, which is an old plastic VHS case with some holes Dremelled out. It’s from a Jean-Claude Van Damne movie in case you were wondering.


Circuit in protective case 

For the gloves, we used two high-heat resistant (425 degrees) gloves we bought from K-Mart. We didn’t actually need high-heat resistant gloves. These were just the only ones that fit with a good amount of maneuverability.

On the left hand, we have the contacts on the fingertips and the orb. The orb is secured onto the glove with hook and loop clasps, aka Velcro. There are two contacts per finger; red for power and blue for data transfer. The ground is in the orb. Please refer to previous post for in depth orb goodness. The four fingers (excluding the thumb) control four tones. When the thumb contact is depressed, the four fingers trigger four different tones. On the right hand, there is one contact and that too when depressed, triggers another four tones. In total, we create 12 tones which complete a scale. The contacts are made from a sheet of copper.

In addition to the thumb contact, the right hand also has a photocell within a wire spool. The spool helps to restrict the amount of ambient light that the photocell is subjected to. The photocell controls the pitch of the tone using pitch bending. More info can be found in Lazlo’s Blog.

The project came together quite well. It required several test models and test subjects to get to this point. There is still some fine tuning that is needed, but I think it is a good prototype.


Gloves at work 

The only thing not pictured is the Korg MIDI synthesizer that we are using to output the sound.

Another note is that we are using two different power supplies. We are using the 4.5V battery pack to power the lights and the 12V to 5V regulator to power the PIC chip.
