[Gordon Johnson] sent in one of the odder active cooling mods I’ve seen. Initially he planned to use lots of pennies to create the heat pipe, but ended up using some copper pipe with some pennies tacked on to mate to the cpu. The pipe carries the cpu heat from the case into a… wine cooler. Judging from the size, I’d guess that the cooler is one of the peltier variety. To see the final creation, I had to go through the slide show youtube video.
I finally ponied up for an ev-do card to make sure that I have no excuse for missing a post short of being trapped in a hole by bizzaro superman.
If you remember the diy ups, you might like the attach a giant battery to a stock ups version. I did this myself years ago. It works well, but use a maintenance free battery to minimize hydrogen off-gassing. In fact, I’d suggest some proper ventilation for the battery pack. Miata batteries have a vent tube if you want to keep the parts count to a minimum. (but they are a bit pricy)
Something a little oldschool – [Alexandre] added a serial port to his newton message pad 2000.(Not in english, but easy enough to understand.)
