PLOG 01-10: The LCD/Fresnel Sled
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):
- Attach triplet lens
- run tests to figure out proper position of lenses and light source
- build and attach lightbox
- work out cooling circuit
- attach fans and put frame into case
- 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.
