Removable Laptop Water Cooling


[Bard] just sent me a nice water cooling hack. He built a simple water cooling system that can be manually inserted into the cooling system of his laptop. He wanted it for watching movies sans annoying fan noise. He soldered the parts together using a stove instead of the standard propane torch. Necessity is definitely the mother of invention. I hope he relocates the water cooling supply. When he wants to go mobile, he just unplugs the cooling fins.

Toorcon Anonymous Presentation

I promised that I’d follow up on some Toorcon stuff later this week, so here it is. I believe I was present for the first ever anonymous presentation at a con. I’ve been waiting for the presentation information to get posted on the TOR wiki, and today I finally found it. The presentation is from the TRON: HE FIGHTS FOR THE USER talk. The idea worked out very well. We could hear the presenter quite well the entire time The combination of TOR, VNC, and Ventrillo was unique. We were even able to ask the speaker questions at the end. The talk opens up some very interesting possibilities. Instead of being able to arrest someone before/after a talk, someone could present on a controversial issue with less fear of corporate/government fallout. Check out the wiki page for more information.

Toorcon Hard Drive Data Recovery


Eliot and I caught Scott Moulton’s talk on Hacking Hard Drives for Data Recovery. You can catch his slides here – but most of the content was in the talk. It was a great walk through of hard drive technology. Some interesting points: 85% of the time, software recovery is successful. 10% of the time, replacing the controller board succeeds. So, 95% of the time you can probably recover your data fairly easily.

Scott showed off a peltier enhanced drive sled for keeping a drive cooled for optimal operation/recovery conditions. He even got into replacing drive heads. If you’ve ever gutted a drive, you’ll know how fragile those heads are. You can actually fold a postit note to keep the heads apart and tranfer an arm with heads from a donor drive to get your drive working again. The difficulty of the operations seem to increase exponentially as the number of platters increases.
