Music Activated LED Hat

Do you have kids learning music? This project is certainly cool way of introducing them to make projects with wearable electronics.

Adafruit has a nice example of lighting LEDs triggered with voice called Ampli-Tie. There are some variations of it on different kinds of clothing. Here I used it for a hat for my daughter who is learning piano.

We took an old hat, cut holes, put metal rivets from Hobby Lobby for LEDs. Adafruit Gemma was used here and everything was soldered with wires. Finally stitches were used to hold the circuit in place.

RainBerryZ and RainBerry3 Outdoor Cases for Raspberry Pi Camera

After a long hiatus, I was able to create two more versions of original weatherproof case for taking Raspberry Pi camera outdoor, RainBerry for Raspberry Pi Zero W and Raspberry Pi 3.

They are available on PinShape and 3DExport.

  • RainBerryZ for Raspberry Pi Zero W – Get it from PinShapeZero
  • RainBerry3 for Raspberry Pi Zero 3 or 2 – Get it from PinShape3

Also available on 3DExport, Pi 3 and Pi Zero.

If you do not have 3D printer like me, you can order them from 3DHubs, Shapeways, Sculpteo, i.materialise, MakeXZY or your local public library.

Here are some snapshots of RaspberryZ.

Than place the seal ring of camera opening followed by place glass cover. Finally put the camera seal and then tighten the screws. Put the seal around the side grove and cut it to fit all sides.

After camera is assembled with M1.6 Size, 4MM. I found it is much easier to use them than M2 Size, 5MM ones which fit tighter.
