Build Twenty Grow Lights

Today I started to build the twenty grow lights. They are for my primeval code experiment. My eyes are no longer the bests for soldering work, so I do the work with a microscope. And 14 of 20 are ready for today.  

Building An Acrylic Button

I want to build a nice integrated keypad for a project, so I'm testing a few methods to create buttons. This one seems to have potential. Two laser cut parts, one is the number keypad and the other one is glued under this one. A small mechanical button and the thing is ready.
