DIY projects

Finally, after almost a year between planning, prototyping, building and coding, my DIY LED fixture came to life. On Sept 6th the woodworking shop, LD Marcenaria delivered the new hood (they are very good, super recommend them to anyone living in São Paulo). It looked good, had dimensions according to the Google Sketch I had drawn, seems strong, etc.

Installation was way longer than just swapping the old hood for the new one because I had to redo the Aluminum structure of the ...

First day of vacations, not feeling well, spent most of the day either at the bathroom or sleeping.... at night I was feeling a little better, so I decided to work on the Arduino sketch, try to finalize v1.0 of it. Testing was still needed, so I proceeded with the test generating sample light curves for the various day types. By day type I mean "clear day", "cloudy day of various intensities", "thunderstorm day", each defined by an Okta number from 0 to 8.

Two weeks ago I had the impression my hammer coral (one ployp) was getting fatter.... well, today I am pretty sure it is splitting into two polyps! That might seem "so what?" to you, but feels very rewarding to me.

Must be a sign ...
