Project: A Maker Loupe

This project is also published on Hackaday.io as Maker Loupe
Commercial Products that work - but don't meet goals and restrictions:
  • Dental Loupes (Links Comming)
What I've tried so far:
  • Simple Magnifying Glasses – hand held and fixed
    • need to be very close to object being viewed
  • Reading glasses (various magnifications)
    • higher the magnification → closer you need to be to what you are viewing
  • Binocular Microscope
    • works quite well but still need to be bent over the scope
    • a movable stage would improve its ease of use
  • USB Microsope
    • not much experience but they can have a bit of a delay (what you see can be a fraction of a second behind what is happening at the moment).
  • Video Scope – NTSC camera, lenses and composite display
    • works reasonably well
      • may be able to improve by moving view screen lower and angling it
 Project Goals/Objectives:
  • Comfortably working with small parts, components, etc. without having to be bend over or bring the parts close to my face.
  • More comfortable – better ergonomics
    • same as above
      • able to sit upright while working (not bending over)
  • inexpensive (under $100 or better yet, under $50)
  • hands free / wearable / light weight
  • Magnification (at least 2x)
  • Field of view (at least 3cm)
  • Depth (about 3cm, enough that working on projects does not lead to neck strain from holding position).
Project Restrictions:
  •  Price - affordable for most people
    • ideal is re-purposed parts 
Updates coming soon.

Update for the Start of 2017

Sorry for the long hiatus ...

Getting to the Finals of the Hackaday Prize and trying to get my project to a functional prototype really burned me out for a little while - I needed a little rest but I'm back now.

Have a look at the winning entries for the Hackaday Prize 2016 (they are really amazing).
I was hoping that I might be able to make it out to the Hackaday Conference (I even submitted a proposal for a talk). Well, I didn't make the cut.  But here are links to the amazing talks at the conference:

Not that I've ever stopped making stuff, just that I took a break from working on my Universal Glucose Meter, etc... and worked on some other areas for a bit.

Here's some stuff I've been busy with since November 2016:
  • Cheapo SphereBot (from salvaged parts)

  • Portable Oscilloscope Build (from kit, mostly) 
  • Reflow Oven (ControLeo 2, some very minor additions from me)
  • 2 Watt LED (445nm) Laser for 3D Printer, CNC (kit build, and review)
  • Sous Vide Build 
I'll link each of these to individual project pages with build information ASAP.
