Wiimote Project

The one problem with your setup that I see is that you would have to replace the rechargable battery after awhile because it can only go through about ten thousand charge-discharge cycles if you bought a normals store battery.

but an amazing set up none the less. Thats the type of thing I am working on right now.

I had a problem which I thought was the calibration being off but it turns out that when I looked at it. my grip had shifted on the pen. so I conducted a little experiment and used human nature to figure out that you do shift your grip after awhile. so it was simply that. It could also be like what you said. someone had bumped one of the wiimotes adn messed that up. but I haven't worked with a two wiimote system, so I'm not sure if moving one would affect the calibration because of what the other wiimote is sending. so if someone could run some tests and figure that out that would be great.

yeah. thats what I was going to get. the tip i had worked fine for projecting on the wall. but one of those switches will work much better. Most of my ideas are incredibly spontaneous so I end up building them out of what is on hand hence the jerry-rigged battery compartment. So when I get out to radio shack I will put a better switch in with the Vishnay LED. Making a good pen.

it works great writing. I am going to go to radioshack soon and buy a different switch and see if that one works any better. The big thing is that you can't use your hand for writing. you have to move the entire hand as a unit when you write but as it turns out when using this as a projected image most people write that way anyway.

it just comes down to you have to write deliberately.

So I've been making IR pens for my Computer Science class and getting incredibly interested in the whole idea. So I built a good pen in which the IR LED was touching the screen. This became a pain when I had to constantly hold the pen at awkward angles to get it to work. This problem bugged the living snot out of me. so I went and built a pen with the IR light in the rear of the pen instead of the front. this allows you to have the momentary switch at the front of the pen to make it so it turns on when you touch the screen. so I wanted to display this idea because I think others would be interested.
sorry about the image quality. my camera is an really old.
