comment How to straighten 32L axles?
I brought a bowl of water to a boil in the microwave, waited for it to stop boiling, then poured into a tumbler, then soaked the bent half of the axle in the water for 2 minutes, then "quickly" put the 32 cross-hole bricks on it and set it up as Jourbarc described, and let it sit for a couple of nights. The axle, while still noticeably bent, appears to be less bent than it was. After I've applied this technique to the rest of the bent axles, I may attempt a second application.

comment How to straighten 32L axles?
I tried this, with 32 of those bricks, and left one of most egregiously bent axles in it for about 2 weeks. I couldn't tell that it made any difference. I'll try the hot water approach next.

comment Can I use the WeDo USB hub with normal Linux distributions?
I think this would be better posted as its own question, rather than as an answer here...

There's still value in getting them straight, even if it's just for the visual aspect. I might also try using them in a high-speed-low-torque application, or maybe put a bunch of worm gears on them to create a leadscrew or something.

comment Is there any other way to program the Lego Mindstorms NXT other than the provided software?
As an example of the programming logic running on another device, my nxt floppy-disk machine used Python on a laptop to control an NXT running the standard firmware.

comment Technic axle corrosion? What happened here?
Take a close look at your Technic bricks from this collection; is there any indication of that kind of "corrosion" on the inside of any of the holes?

comment How can I blow a stream of air for up to two minutes at a time?
I think you'll find that studs-up construction for the housing will give you enough air-tightness. My concern would be if you could get enough pressure from it... I'm not sure how much it would take. You might try experimenting with a hair dryer, shop-vac, and small fans and the like to see just how much air you'll need. Building a squirrel-cage fan is a fun little project all on its own, too! :)

If only those had come out early in my "HO train"-phase instead of the middle of my DarkAge....
