Title: How Wacom's work

A detailed explanation on how the Wacom technology works:

And the main page of the site (mainly a corporate site about the penabled technology):

Fantastic find.

Yeah, seems like they sell components, but quantities liable to be high.

You can buy just bear sensor boards, I wonder if that includes the kit needed to get them working. Intresting some of them even claim LCD support and stuff. Its all a bit unclear.

It would be interesting to see if the information on this site can be used to develop a technique to somehow scan an LCD monitor while it's turned on, to see if it is going to cause the interference with EMR.

I purchased three LCD monitors yesterday on Craigslist here in the San Francisco Bay area, and had the guy connect them to my laptop and turn them on to prove they weren't dead. With such a technique, I could have very easily scanned the monitors at that time, and declined to purchase if they showed interference.

Granted, this won't be very helpful to those procuring monitors via eBay and the like. But just imagine: walking through a large electronics retailer, and scanning all manner of makes and models. The result would be a much broader picture of which ones just won't work.

Ahgh! Newbie talk too much. I'll stop now.

I'm going to go straight ahead and say that is physically impossible.  Even if you had some sort of scanner it would not be discreet and would most likely have some sort of radiation or some other type of thing (maybe not).  Also, you have no idea what type of shielding is inside of the lcd etc..  The only real way is to test.

I am not 1000000% sure about this and please somebody correct me if I am wrong.

The best we've managed so far is to try drawing with the tablet on the screen before disassembly.   The theory is that if you don't get jitters it is either lucky frequencies, or the bad stuff is being shielded, so should work with the right shielding once done.

Thats not a bad tip actually, you could take a Volito or similar small tablet, be up front about what your testing for and test it. That been said 99% of people from here got their screens from ebay.


As for a real test, basically the problem with interference is that something is playing up with the magnetic field, so something like a itchosketch board but really sensitive may show up the interference. In Theory, trial and error I think is the best way.

Interesting sites.

Leads me to think I might be able to build my own pen...........

Hmmmmmmmmmmm

Now that would be impressive. Youd have to know the reporting frequencies etc.

Now I am further encouraged to think this one through.  ;)  But to be able to devote the time, I cannot. I have not won the Powerball yet.
It sucks to be a full-time peon to a home improvement center.  :P
