I really need to know if there has been any research into this - and if it's possible to help the wiimote see the ir source better by using multiple LEDs? I am using quite a large screen - and a standard projector that needs to be a few metres away.  Is there a definitive guide on maximum distance the wiimote can see as standard and what the maximum screen size is with one wiimote?

IR Pens / Really Bright LEDs - Instead of Vishay? Rear Projection
« on: September 28, 2010, 06:26:36 AM »
Hi All

I have bought 3 pens from ebay (wiimoteproject) was the user  - and used one to convert into a spray can - but using with a rear projection screen it doesn't seem to work very well. It's actually not quite as bright as the other pens - even though it has the same led - the famous Vishay  or at least that's what the listings have said!

Custom made IR pen comes with:
High quality VISHAY TSAL6400 infrared LED
3 watch batteries (AG10 - 1.5v)
IR led specification
Size : 5mm
Wavelength : 940nm
Viewing angle : 50
Forward voltage : 1.35V
Forward current : 100 mA
Radiant intensity : 40 mW/Sr

Also - having read some information about making pens - shouldn't this setup have a resisitor in it?

I'm wondering whether there is some way that I can use a brighter LED to be seen better through the rear projection screen. Maybe like the ones used in security lights? Any BRIGHT ideas? ;) Like maybe using a reflector or something too..?

I've been looking at making my setup into a sort of booth. Maybe like a large rear projection TV type affair!

My current projector needs to be about 3m away from the rear pro screen I have 244cm x 18cm (305cm diagonal) It's a da-lite fastfold.  I put the wiimote on top of the projector. Calibration is usually around 82% but I still have issues in the corners and a dotted line. Maybe its the power to the LED that's sporadic?

I'd like to be able to have a smaller area behind the screen - that I can box in to make it all neater. I was wondering about using an Ultra Short Throw projector that will need less space - or else trying to fold the image using mirrors.

The other thing about using a booth would be it might help with reducing stray ir light.

Anybody have experience of this? One of my concerns is that with a shorter area - the wiimote might have trouble seeing the whole screen. Should I use 2 at the back in this instance? Or would I be better off looking at using freetrack and a webcam instead with a wide angle lens fitted?

I saw this earlier and wondered whether this could be changed to work with the wiimote?

General Discussion / Multiple Pens ? Or Is only one possible?

I wonder whether it's possible to use multiple pens at once. I've seen a system that allows 5 users at once for a digital graffiti wall - of course it might not use a wiimote - could be something else?


I'm Craig, and I'm self employed as an artist and designer mainly working in the conference industry creating high end presentations for corporate clients and production companies

 freelance and technical manager for Crystal Interactive audience response systems.

 I'm also employed part-time as Digital Youth Adviser for Birmingham Diocese of the Church of England.

Interested in using the wiimote and associated projects for digital graffiti and for presentation at conference and live events.

Excited about the possibilities and would love to find someone who can help build a flash app for the graffiti thing...

Also quite interested in investigating how twitter can be used for voting systems, and live feedback at events

Another project I'm involved in is Ulfilas Christian Goth International

Just found this freeware app...

does the trick!   It can also stay on top of other windows.. I'll be using t with ArtRage 2.5 for digital graffiti for now - until someone helps me develop an application in Adobe Air that does exactly what I want!!!

I have already seen a few of these available for hire - and - there are others too.

friispray is offering its software as open source and free to download. I have also been looking at using ArtRage 2.5 (3 coming out later this month) as it's got a minimal interface.

there's also which is looking like it will become a full nintendo game. It has a spray can like housing for the wiimote

I'd like to make my own - using an IR lamp in a spray can. BUT I would really love to be able to do right click as well as left click... maybe a cobbled together solution attaching parts of a wireless mouse to the spary can? with just the right click button (anyone tried this?)

There's also the issue of software. The uses their own flash software with customise options - they're expensive to hire (2500 a day +extras)

I have seen good source for Flash drawing things - open commons. I'm not a coder - but maybe someone out there is and could look at it?

I would love to work on this project with someone - I'm in Birmingham UK

Hopefull I can post URLS here!
