Project boxes can be a real pain. You can get a standard size box from a place like Radio Shack or you can make your own custom box. If you have access to a laser cutter, you can make yourself t-slotted boxes. While the t-slotted boxes do the trick, the open slots leave an unfinished look to projects.
I wanted a more polished look for my latest clock, so I set out designing Låda. The Låda (or Lada) Sytem, based on standardized 3D printed corner and edge pieces and custom laser cut face pieces, allows you to define a box of any size bigger than about an inch and a half on a side. A program written in Python does all of the tedious calculations for you and spits out a PDF file. Custom openings can be added with InkScape to accommodate stand-offs, buttons, cords an sensors.
The edge and corner pieces have mounting holes 0.4″ from the inside face. They have an elevated platform to cradle your project. Hex cutouts captivate a M3 nut so that once installed, they remain in place and the box allowing the final face to be screwed into place. +Kevin Osborn has been keeping our 3D printing non-stop so that now I have plenty of Lada pieces to play with.
The Lada system works fine for small projects like the EL-Wire night light seen above. It also works with larger projects, like the Kandinsky Klock (or Kandy) for short.
About the projects:
Halo is an EL-Wire night light configured to outline a doorway. It helps to prevent falls by both providing light, and creating a frame of reference to orient you if you need to be up in the middle of the night. I made it for my father who could use a little assistance getting to the bathroom in the middle of the night. The idea comes from a story I heard on NPR.
A special thanks to +Kevin Osborn who lined me out on what I needed to drive EL-Wire and pointed that the Grove Started Kit had everything I needed aside from the inverter.
Kandy is a two-sided mountain bike race timer that I’d promised to build for my collage roommate two years ago. It is 4 TiM boards with c prototype LED controller called TiNA. It is bluetooth controlled (thanks to the FTDI compatible BlueFruit module). I think it is worth the wait.
None of these projects would be possible without Anool’s tireless work designing amazingly flexible circuit boards.
