Improved Dutch helix/helical for WLan
Below you'll find the description of a 22-turns helix antenna according to the downscaled design.
Both sides of the reflector have edges with a V-shaped cut. This is to mount the antenna easily to the mast, using a simple clamp. The V-cut must be beside the center line of the reflector to prevent for the antenna mast obstructing the N connector area.

3style Adds a Jogwheel to Your Mouse - Gizmodo
his 3style Mouse combines standard mouse design with a jogwheel, an input device familiar to video editors everywhere, to create a new and pretty awesome looking way of controlling your computer.
The entire top surface can spin, allowing you to scroll through documents or quickly spin through footage with ease. Since the entire top surface rotates, there are no buttons on the front. Instead, pressing on the top is a button and squeezing the sides is a button.
Check out the video after the hop of how well this thing handles boring stuff like knob control and fun stuff like first-person shooters. No word on pricing or availability.

iBook Logic Board Repair – Reflowing solder of graphics chip.
A DIY iBook Dual USB Logic Board Repair - MacNN Forums
I have an iBook with a dodgy graphics chip. iPlay at fixing it. iblog about my adventures.
1. A gradual increase in temperature, of about 1 to 3 deg. up to a temperature of 150 deg C (302 F). Pre-heating is extremely important so boards don't warp. It may take a minute or even longer to pre-heat...No need to rush it. Flux activation begins at 150 deg. C (302 F)
2. Through the flux activation phase, a slow ramp up of temp. to a peak of about 180 degs. C (356 F) over about 90 seconds. Reflow begins at about 180 degs. C (356 F)
3. A gradual increase during the reflow phase to about 210 degs. C (410 F) for 60 sec.
6. Cooling phase should then begin gradually, not abruptly.
I found a really good graph of the temperature curve here:

So, as long as the heating is gradual and controlled you should be able to reflow the solder without frying the rest of the board. Yes...the whole board will get quite hot despite masking everything around the video chip. As long as it's gradual and controlled, you should be OK.
You may also smell the flux as it heats up, which is normal.

They may have been quiet but passively cooled graphics cards have generally been pretty poor performers or needed complex and costly heatpipe designs. But with the arrival of Nvidia's GeForce 7600 GS this has all changed, and you can get decent performance at a decent price without the decibels...
