This instructable shows how I made a laser cut box with a curved lid to house a wireless sensor node. I made it at Techshop SF
. The node measures temperature and relays its measurements to a central logger so that I can plot graphs from the data. The box needs a port for the antenna, good air flow for the sensor and it needed to be attractive so it can sit on a shelf unnoticed.
I did all my laser cutting at TechShop San Francisco. It was my first attempt and 2 of the 3 boxes that I made worked out but one broke when I tried to bend the lid into place. I tried 3mm MDF, aromatic cedar "laser wood" from www.laserbits.com and birch "laser wood" from the same. The MDF cut and bent perfectly; the cedar burned quite a lot in the cutting (more on that later); the birch cut well but it was too thick to bend.
[Update] I've now improved the design (pictured) and it works perfectly with birch as well as the other woods. See the final step for the updated design files.
~3mm laser ply or MDF.
6 x 10mm M2 screws and nuts.
1 x wireless sensor node (mine is my own design but a friend of mine has written up a very similar one, from which mine is derived)
1 x laser cutter, I used a 60W Epilog Helix.
The design files and code are available in my github
