For more information abut the Eyewriter 2.1 update that I am working on, check out all of my blog posts related to it: http://jason-webb.info/tag/eyewriter-2-1/
I am also maintaining a condensed wiki page for the project here: http://jason-webb.info/wiki/index.php?title=Eyewriter_2.1
If you'd rather watch a video showing the assembly process, one is available on Vimeo here: https://vimeo.com/77366693
This Instructable got Featured, which earned me three free months of Pro membership! This means that I can now embed the actual assembly video here for you :)
Step 1: Gather all of the parts
All of the printed parts are available at this Thingiverse page. Printing instructions are also available on that page.
- 2 x end blocks
- 3 x platform clips
- 3 x extension arms
- 2 x glint modules
- 1 x main board mount
Look for these hardware items at your local hardware store. But if you live in a place that does not have many metric parts, I've included McMaster part numbers so you can buy them online.
- M8x~20" threaded rod (McMaster: 99055A125, cut to size)
- 4 x M8 nuts (McMaster: 90592A022)
- 2 x M8 lock washers (McMaster: 97985A590)
- 8 x M3x14 machine screws (McMaster: 91420A517)
- 6 x M3 lock washers (McMaster: 91120A120)
- 6 x M3 wing nuts (Grainger: 26L006)
- 2 x M3 nuts (McMaster: 90592A009)
- 1-3 x M3x20+ bolt (McMaster: 92005A128)
Making the threaded rod
You can make your threaded rod any length you want, but I find that ~20" works well for clamping onto laptops and 17" or 19" LCD screens. If you are not able to directly buy an M8 threaded rod at the size you need, you can easily make your own (if you have access to the right tools).
Measure your rod to the length you want, then cut it to length using a chop saw. This will result in a rough edge, which is not only dangerous, but impossible to thread a nut onto.
Use a bench grinder to smooth the end of the rod out and give it a little bit of a taper. Make sure to test out both ends (cut and uncut) by threading an M8 nut to see if you need to do any more work.
