One can extend the mechanical controls on the opt-mechanical device with Lego and can also possibly servo control the impossible optics. http://openwetware.org/wiki/User:Pranav_Rathi/Notebook/OT/2012/01/12/Extend_your_Opto-mechanical_controls_with_Lego_for_out_of_box_control#Design_and_construction

1. Extend your Opto-Mechanical controls with Lego for out of box control by: Pranav Rathi Koch Lab UNM

2. Create attachments A knobs A knobs 8-32 nuts Y-axis X-axis

4. 4-40 nuts X-axis

5. Prepare gears and choose the right screws

8. This is the unfold view of chassis frame

9. Design and construct the chassis Gear Box

10. Gear Box

11. Screw-in the chassis directly on the frame X Gear Box

12. Y Gear Box X Gear Box

14. Prepare the control knobs B Knobs Universal Joints

16. Attach the knobs Y Gear Box Knob B X Gear Box

17. Due to Lego universal joint the knob does not have to align with the inputs

18. This is how it works?? Rubber washers

21. System for QPD

22. System for QPD

23. System for Steering lens

24. System for Steering lens

25. Microscope Control Knob A Universal joint Knob B

26. Microscope out of box control

27. Next step is to attach step motors to servo control the optics
