How do you recomend  sync up to bluetooth?  I had similar product but users found it difficult to press the  1&2. They didn't like pulling out a ladder or stepping on a chair every time they wanted to use it.

Hi,
Check out this rather long post to overcome remote syncing.

I also have developed a way of connecting 3 volt door chimes to the wiimote so that both the wiimote and doorchime are powered by a single 3 volt AC adapter. You can now turn the wiimote into discovery mode with a simple press of the remote button from anywhere in the room. Costs $11 and about half an hour of modifying and simple soldering.
 
The fishing line is by far the simplist and the cheapest option though.

I have also developed another way to remotely put the wiimote into discovery mode. Much simpler than hooking up the wireless doorchime, much cheaper and will require no battery changes ever. It's along the same line as the fishing line concept but is electric. As soon as I meet with the Uni on the 3rd November and demonstrate, I'll post the procedures for both these concepts.

All my wiimote setups are remotely accessed. This is the only way to go especially if you want teachers to take this cheaper alternative seriously. The best thing, it still only adds a couple of extra dollars to the whole set up.

I'll keep you posted.

Cheers,

Joe.

Hi teachwithtech,
If you use the rechargeable battery packs as pictured above, they will eventually die if they are being subject to a constant charge. It is a far better solution to purchase a 3 volt AC adapter and connect it to the terminals in the battery compartment or pull the wiimote apart and solder the wires directlty to the positive and negative solder spots on the circuit board.
You get a constant and reliable power supply of over 96% the entire time. I have had a wiimote connected this way permanently now for 8 months straight and no issues whatsoever.
Lately, I haven't been shutting the laptop down at the end of the teaching day so the wiimote just stays connected all week. Walk in each morning, turn on the data projector instant IWB just like the pros!
Cheers,
Joe.

The wiijiiboard.com (banner ad that sometimes appears) appear to have a permanent power solution that doesn't involve a battery pack

I'm going to weigh in on this as these are items I am extremely familiar with. First, this type of battery insert is not approved for use in the US. A person would be wise to steer away from them. You won't find them being sold by any "normal" retail outlet. The voltage drop from 5V to 3V is achieved with a resistor - that's all. The batteries are NiCd which are pretty much obsolete.

That being said, I sold many of these early on and then stopped to find better US approved devices which I did.

If you are in the US and purchase one of these, buyer beware. There is no warranty and no guarantees. I can't fault anyone for wanting to be economical but safety is a greater concern in my opinion.
