An IR Blaster Project, in a Nutshell

What happened

The speed that computers have gotten smaller is a bit mind-bending. And, although it seems like the speed at which things are getting smaller and faster has slowed a bit compared to the rapid pace of the 90s and 00s, some truly minuscule computers are accessible nowadays.

So much so that it’s possible to do useful computing inside a walnut shell . The first step in this build is to crack into a walnut.

Most have a natural seam that separates two hemispheres, so splitting it open, enjoying a small snack, and then adding some small neodymium magnets on the inside of that seam to close up the shell is not too difficult. Hiding projects in unexpected places is a fun pastime, like this Meshtastic node hidden in a landscape light .
