[extropy-chat] Birthday Wish List

[Gina Miller]

I have actually had a (recently neglected) home built STM project in my garage that has been there for a few years now. I have designs, although I am missing a few key specifications on some of the parts. Specifically the oscilloscope, the diodes and the piezoelectric element (which only requires one). Although there are methods of prevention in my crude schematic, even if this design was to be accomplished there would still be some vibrational stabilization issues. There is no rush for me to figure these problems out right now. I would like one day to return my focus on this project however right now my attention is on 3D animation. At any rate, you still have a whole day to ship my AFM! : ) Gina`

  Atcually there is a much simpler and cheaper STM design. I'm currently 
  trying to buikd it. It's based on a
  "unimoph" piezo element which costs $2.00. This replaces the three 
  expensive piezo elements in the Muenster design.

  So far, my cost is still below $500, including the cost of machine 
  tools. I intend to publish the design, but only after I
  get it to work. It's based on
     http://www.geocities.com/spm_stm/
  But I have made some simple modifications.

  Unfortunately, while STMs and AFM are conceptually similar, they are 
  very different in actual implementation.
  Therefore a super-cheap STM will not necesarily lead to a super-cheap AFM.

  If the unimorph concept works for the STM, it may be possible to extend 
  it to permit multiple probes to operate
  on the same field.  this is may prove more useful than an AFM
