PLOG 01-10: The LCD/Fresnel Sled

without comments

The main frame is coming along slowly. I’ve finally got the LCD/Fresnel Sled done, here are a couple of shots.

I’m not too sure what’s up with the lighting. Maybe using flash wasn’t such a good idea.

So far here’s the list of materials I’ve used:

  • Metal Rails from IKEA “HYLLIS” Shelf (Hardware shops were selling for $1.50 a foot.. this one was way cheaper. Plus I got some shelves to play around with.)
  • Nuts and Bolts from nearby hardware shop

I’ve also already cut the remaining lengths of rails that I intend to use. I’ll be uploading my current design idea in the next post (this one is just a quick update).

I have been working on this for almost 3 whole days (not nights, though, I’m a good neighbour and don’t intend to wake up the neighbourhood with my drilling). I’d love to keep going at this rate, but unfortunately I have a test coming up that I have to study for, so this will be done only now and then, during study breaks or something. You know how priorities are.

Here’s what I have left to do (in the order I plan to do them):

  1. Attach triplet lens
  2. run tests to figure out proper position of lenses and light source
  3. build and attach lightbox
  4. work out cooling circuit
  5. attach fans and put frame into case
  6. take care of wiring

Hm, quite a bit more to go… I’ll give it this week until Saturday. If by then I still have a long way to go, and depending on my studying progress, I may have to put this on hold until I come back again next summer.
