Cat Laser
Description
A DIY laser pointer using a common 650nm 5V laser diode with copper head and a tact button. Used the excellent 3AAA flexible case from enif with the necessary cabling. I used 6x6 tact switch, with also 9mm tip high. Use both contacts on the tact switch in parallel. Need to design a cap,but thinking how to make one to protect the button from accidental push. Update 28/4/2020 I designed a simple top cover. Be aware, the design in the freecad file is not to be taken as an example !!!!
