I made this pen http://stru.calvin.edu/WiiProject/index.htm
with a friend and we were thinking of possibly making some more and even possibly sell some of these pens or just the machined parts of the pens to sell as a kit. 

However, because these are labor intensive to make (as opposed to stuffing the electronics into an existing marker casing (see my post on March 28-2008 or search for "ear plug")they would most likely be in the $40 USD plus Shipping range.  Is anyone interested in purchasing a tip-switch pen or possibly interested in making them somehow to get the price lower?

I'm working on my design for a tip switch pen with adapts from the one I have here http://www.wiimoteproject.com/ir-pens/another-good-idea/

it will have the LED in the front. I'm using just radio shack parts. if you look into any major eletronics provider like Digikey.com or mouser.com 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.

Only few of us can see. even less know of that ability and even less than that can actually use what is theirs. Now why is it that those who are blind leading those who can see?

Given your pen offers greater functionality (specifically using to write digitally) and looks professional (custom body rather than retro-fitted marker) I don't think the cost is too expensive.

Once you achive economies of scale and improvments in manufacturing technique hopefully the cost can drop and you will be able to sell more.

I think you will need a video or something concrete to prove your pen is superior to the switch variety if you want success at that price point.
