Summary

Laser harp's pentad sensor with lens stabilizer. Can stabilize laser harp's beam.

Instructions

1.Make circuit with iModela. Setting is milling depth :1mm/path, speed:1mm/s.
2.Make circuit with phototransistor and resistor(10kÎ©) and 7pin pin header.

3.Make two lens holder and sensor base with Modela or 3D printer.
4.Get five film with lens's main lens(f: 28mm).This is called ä½¿ã„æ¨ã¦ã‚«ãƒ¡ãƒ©(Tsukaisute Camera : means one time use Camera) And can get from print shop.
5.Sandwitch lenses with lens holder like skp file.
6.Assemble all parts like skp file.
