DIY Scanning-Tunneling-Microscope

Anonymous Coward writes "Quote: To give everybody an opportunity to make his own "hands on" experience with the Nanoworld we provide all information to build up and use some of the standard equipment of this fascinating field of science, starting with the Nobel-Prize-Winner of 1986: the Scanning-Tunneling-Microscope (STM). Just follow these handy Instructions" While construction of a stm from these instructions isn't cake, it will give you a good idea of what goes into the building of such an instrument.

How interesting

Interesting CAD drawings... Particularly the professor's name, in the lower right...

Now THIS is News for Geeks!

Very cool, and astoundingly understandable, considering that the authors aren't native english speakers.
It's so neat how they've adapted what, after all, are some fairly pedestrian and accessible tech to achieve such a noble goal!
I especially enjoyed the brute-force electrochemical solution to producing a tip.
Massively k3w1!

diy not unusual in science

I'll admit that it is pretty impressive that they've got something that works with such a simple design like this, but do-it-yourself isn't really an unusual phenomenon in academia.

When people (well, science students, grad students, and professionals, at least) think of scientific instruments, they tend to picture big complicated NMR machines, mass spec devices, HPLC systems, so on and so forth, with proprietary interface and database software, and service contracts that run tens of thousands of dollars a year.

These big instruments are manufactured and supported by huge corporations or little startups, and either way, the manufacturer will only design and produce (and support!) these devides if there is a sizable consumer demand - something to make it economically worthwhile to try and fill the niche. But for any given technology, there was a time before that particular technology was commonplace and mass-produced.

HPLC systems, NMR devices, CD spectrometers, X-ray crystallographic devices... (I'm a biochemist, so I apologize if my examples are skewed in that direction) these all started out as projects imposed on graduate students by research advisors in some budding new field. These first pioneering instruments, which worked well enough in many cases to generate fantastic data, had to be slapped together from off-the-shelf components and with a tight budget in mind.

Not to detract from the oo's and aaah's, but its good to keep things in perspective.
