Networked Whiteboard?

Anyone interested in a networked version of this, sort of like Pictochat? Bg

I would be if wii (I mean we) keep it to WiiBrew members so there is a responsibility control setup. This will stop some of the trouble from happening. Pinball wizard 17:38, 14 June 2008 (CEST)


It's - just a shame that I don't have an IR pointer. Bletotum

Build your own!

Needed components

  • An IR LED, maybe from an old tv remote.
  • Two AA Batteries, most LED run on 3v
  • Momentary button, go harvest from that old radio you have or something
  • Chassis (something to make it a "pointer", so you can actually point with it.

Kind of optional

  • Soldering Iron
  • Solder
  • Flux!!! (if you're soldering, this is key to everything!)

Really, you should use these, but you can tape it together, kinda ghetto, but will work, at least temporarily.

Now connect the stuff together

I'll put up pics later, and I forgot the no-format tag.

Look at that, it did it automatically :) GizmoTheGreen

Careful though, check your LED's specs first. I haven't seen many IR LEDs that run on 3V; most I know run on 1,2V-1,5V so you can connect them to a single battery and will probably fry them if you connect them to two batteries without a resistor, like shown above. Bg

I built mine a few months back from parts at RadioShack. One thing the above design is missing is a resistor, which is important if you want to have the LED on for a while without burning it out. I forget what value I ended up using, but check the amp rating for your LED and use V=IR to estimate what R should be. Exactness isn't that important, just something to restrict the amount of current going through your LED. The wiimote sensitivity screen is very helpful for testing whether your IR pointer is producing any light and whether it's bright enough. Ulti 17:23, 22 May 2008 (PDT)
As you only click when your drawing, i do doubt youll be drawing one single line for more than ahalf a minute. so i really see no need for a resistor, but sure, if you feel one is needed, add one. there is several resistor calculators on the web.and a quicker way to tets the IR LED is to use your camera, in camera phone or whatever, webcam, youll be able to see the light. better than going into the senitivity screen as it takes alot more time, starting wii, connecting wiimote and going into settings bla bla, i just take my cell out of my pocket, push a button to get into camera mode :) GizmoTheGreen

Use the classic controller's connector

Nyko makes a classic controller piece that adds grips and attaches the wiimote to the back of the classic. You can unscrew the piece that holds the wiimote and use it so you don't have to use duct tape. Odb718

I saw the instructions on the page for the one that is used with - the computer.

And I failed horribly at making the pointer. I'll just buy one from some - one. Bletotum

2nd WiiRemote

Perhaps I missed something in the Video, but what is the need for the second WiiRemote if only one is acting as an infrared camera? All I see you using to interact is the infrared light pen, and not a wii remote.

The "first" Wiimote is for pressing buttons (Calibrate, Back, etc.) and the "second" is used as the camera. I'm guessing the reasoning for this is so that if you needed to get back to the menu or wanted to recalibrate, you don't have to press a button on the camera and move it slightly, therefore putting it out of calibration. Is it necessary? Probably not, but I see why bg did this. pezjono 16:17, 22 May 2008 (PDT)Pezjono
It's not absolutely necessary. The code is pretty easy to hack up if you want to change it to only use one wiimote. Just be sure to use the CVS version of libogc since wpad.h doesn't exist in the current DevKitPPC release. Ulti 17:14, 22 May 2008 (PDT)

Where is the "thx to GRRLib" Dervers ? ;)

Sorry, it's in now.
