IR Pens / Re: Battery life - what is your experience?
« on: October 08, 2008, 02:01:31 PM »
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've been doing alot of testing on my pens so far. I've gotten at least 6 hours off of a single "n" sized battery. I haven't had time to test any "AA" or "AAA" yet. but when I do I'll throw those up too

IR Pens / Re: Tip Switch pen - Part 2 Drifting calibration?
« on: October 07, 2008, 08:07:17 PM »
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.

IR Pens / Re: Tip Switch Pen - too costly to sell?

I'm working on my design for a tip switch pen with adapts from the one I have here

it will have the LED in the front. I'm using just radio shack parts. if you look into any major eletronics provider like or they will have all the parts cheaper except for the marker.

the big thing is you have to find the parts that you absolutely need and find the cheapest ones. then find what you can for the actual body and work from there. Its a learning experience. you need to find a cheaper way of doing it. its mostly what you can think of and design to make it easy to do.

so have fun with it.

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.

Hello everyone.
I'm not new to the idea of forms since I have spent alot of time on them
through the Ubuntu forms. I love Ideas Like this I spend alot of time working on
stuff like this. I tend to do before I have things thought all the way through. but
I make them work out anyway. I hope I can gain a lot form this form but I hope I can put in even more.

so peace from the small but infamous town called Blacksburg, Va

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.

I'm currently using a radio shack IR LED. which isn't worth the money I spent on it. I'm waiting for some vishnay TSAL 5300's to come in. but I've used it, and had no problems when it comes to angle if you hold it the same way you hold a pen even on a projected surface. its best for this design to have the wiimote up higher to the side you are handed. so I had mine up to the left, because I'm left handed. the reason I posted it was because I hadn't seen it any where in the forms else wise.

IR Pens / Another good Idea
« on: October 05, 2008, 07:39:00 PM »
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.

thats a really cool pen. do you think you could put up instructions on how to build it?
it would be much appreciated.
