Active Antenna parts
The ActiveAntenna board picture is too small/blurry to read the chip part numbers. Could you fix it or, alternately, just read off the part numbers? I think I know the big one already, the 88W8388. There are two interesting ones below that.
What is under the can? (maybe you can pop it right off; that works with some Marvell devices)
What is on the back?
I'm especially looking for part numbers for EEPROM and FLASH devices.

Dissasembly of keyboard
I see that you've edited the disassembly of the keyboard section to include the statement that it would not work. This is in direct conflict to the evidence which is that taking the keyboard apart does indeed resolve the sticky keyboard - whether it's due to removal of contamination or "fluffing" of the contact spacers, I have talked to 3 users that have mostly solved their keyboard problems with this procedure.
As long as one is out of warranty, what other recourse does the XO user have. Until you get replacement keyboards out, folks will try this process and many will be helped. Alc 16:21, 20 April 2008 (EDT)

Your supposition about frequency response is not correct. There are almost no capacitors at the front end to act with the 100k's as a low-pass filter. Moreover, the laptop's resistor value is quite low, about 1K as I recall.
If you make the grievous mistake of sticking the unprotected port inputs into 120VAC or 240VAC the "chassis/frame" including the port's metal shell will be come live.
The laptop's small-value input resistor does does not protect the input diode/tranzorb at the front end. So if you reverse a 1.5 volt battery polarity (i.e. minus into the port) you'll blow the diode. I've tested this with decent current limiting power supplies.
The 100K's are a very low-cost stop-gap and do not represent particularly good design. To avoid safety issues and potential damage to the laptop you should build the differential amplifier (it costs less than $10). This will protect you from frying yourself and/or the laptop up to 240VAC. There are some design simplifications and cost reductions possible that I came up with.
My personal rule is this: do not post anything that can mislead and result in damage to the laptop or harm to the student. Bill Wvbailey 17:09, 30 December 2008 (UTC)
Wedding Cake Topper is an old but young artist. saying it is old, that's because we have thousand
year of history,industrious and wisdom ancients made the equisite pottery,while with
the trend of contemporary society, a lot of personality factors are added in them. Some
designers use different colours of pottery to make different facial expressions and
poses according to the real person's photo. Those dolls are lifelike.
There are varieties of dolls, like the superstar, elegant women,amiable old
man,innocent and lovely children, each of them are adorable. Some fimo dolls have
complicate scenes, like bathroom and couch. The reason why we think they are
personality is that each fimo doll is made according to real person, the cloths and
background are all depends on the customers. Only a front and a side photo is needed,
these personality Bobble Heads were originated in Europe, and then came into
Taiwan,China. They are called personlized fimo dolls.
The materials of fimo dolls are colourful, it feels soft, and looks like plasticine,as
a matter of fact, it is polymer clay.They are with high ductility and plasticity, good
flexibility.Different colored soils can be polymerized to make varieties of patterns
and shapes. It takes 2-3 hours to finished a fimo doll, and then take it into the oven.
After baking the doll, it can be kept for a long time.
