This particular design is simple in order, more for the sake of keeping my short attention span on track for long enough to actually get this finished!
Let me know if I've missed some detail and I'll correct it.

Warning: Even a low power laser can cause permanent eye damage. Always wear safety glasses and never point at people, animals, or police helicopters!
Step 1: Materials and Tools
This guide shows the set-up for slides made from overhead transparencies.
I will use the Dinkle rails and polymorph pellets.
- Green laser module 10mW+
- 1 solid length of wood (~90cm)
- polymorph pellets (or a willingness to create lens holders from wood, plastic, etc)
- concave and convex lens. You can get these from old disposable cameras which camera shops will throw out by the dozens.
- Hardware for attaching rail to wood (bolts or screws, depending on method).
- Dinkle rails, with 72mm rail modules (x4), and the mounting feet (x8), available from http://www.altronics.com.au/ (note, you may find a better way of mounting the parts, but this one works for me).
- perspex or pcb 72mm with for Dinkle mounts.
- Jigsaw or handsaw
- Hole making bits for drill (if using wood to create lens holders)
I will use the Dinkle rails for this instruction simply because they make alignment so much easier. They also allow a great degree of modularity - being able to swap different lasers, lens, etc in and out quickly.
