Based on this sketch from Alex, I used Fusion to design the parts, lasercut them out of 1/8" plywood. All the little holes are for 1/8" dowels. | |
Last year, I saw that the servo arm that came with the servo was too short to fully flex the fingers. So I printed some new ones. They have different inside diameters, to determine which one would fit snugly on the servo shaft. D is the best, E,F too loose, A-C too small. [printed with PLA on the Prusa Mini, 100% infill, no supports.] | |

OPTICS
From here:
about halfway down (Wed June 8)
Wednesday, June 7, 2023 Optics 12:15 to 12:30 Lasers and Laser Pointer Safety Adriana 12:30 to 1:00 The wave nature of light Laurie Ask “What is light?” (Energy – ability to do work – what is work, move stuff heat & push around) Demo with Crooke’s Radiometer Show video of solar car Particle vs wave Definitions, wavelength, constructive/destructive interference Hubert’s strips Online ‘Ripple Tank’ EM chart measure UV and IR with the laser meter and rainbow What part of the chart do you work with? Interference patterns – laser with diffraction grating Demo Interference pattern – cloth (Priscila Rosa did the hair measurement Tuesday) 1:00 to 1:30 Taking Light Apart and Putting it Back Together Laurie Discuss rainbows – demo with glass of water Make rainbows with triangular prism, collimator, and flashlight Make rainbows with diffraction grating and flashlight Demo how different colors bend differently (with lasers) time??? Combine colors and make white with colored flashlights Talk about absorption of light Also use colored flashlights with prisms Discuss the Dress “Step into the Rainbow” while playing with prisms 1:30 to 1:45 Break 1:45 to 2:15 Reflection and Refraction and Absorption and Scattering Demo reflection/refraction with laser refraction tank Laurie or someone? Total Internal Reflection (light guides, waterfall) Hubert Introduce 5-laser/prism boxes, look at focal length, etc. Index of Refraction Grow spheres in water Laurie Snell’s Law calculation Hubert Laser Microscope with dirty water Laurie Sky is blue tank (get the eggs) Laurie 2:15 to 2:45 Spectroscopy Infrared and UV examples Demo with IR/iPhone camera, UV Look at Various objects with UV lights RSpec Explorer with gas tubes and light tower Show spectroscope examples Use the spectroscopes they made as Tuesday night’s homework Fluorescence and phosphorescence demos Invisible ink pens and phosphorescent paper, write with blue laser ================================================================== | |
