As soon as I have a work bench area, I’m going to start getting into this stuff. The idea of having a headphone amp that I put together all by myself is incredibly attractive to me for some reason. I’ve messed around with old analog audio gear a bit but I’ve never had the parts or expertise to do anything constructive… but you don’t have to be like me. Got the necessary tools and a love of audio? Check out this how-to.

If you’re paranoid about having an exposed vacuum tube, see what you can find out about hacking some of the newer digital amps out there — I hear some are quite good and you could certainly cut and paste a few pieces and make one more portable and appropriate for headphone use.

I mean, you could. I probably couldn’t.

Here’s a selection of yesterday’s stories:

DIY: Build your own vacuum tube Tesla coil
Someone obviously wants the crowd-developed Cable Caps, but I don’t
Forget the whack-jobs, the NASA photos don’t show trees
Finally! USB-powered latte foamer
Disgusting: The GUMMI-X toy kit is an edible insect maker

Who doesn’t want their own Tesla coil? Particularly if you can get one that isn’t incredibly dangerous or expensive to build. Well, this electrical savant built one in the 8th grade using vacuum tubes and a microwave oven transformer.

Safe is relative of course, but this isn’t quite as intimidating as some other Tesla coils out there. The steps are fairly clear, the author included a schematic, and I might just have to make one of these myself. Rather then rehash the steps here, I’m just going to direct you to go to Make and see the complete 10 step process (including parts list).
