Originally I was going to prepare a Stevenson screen for threshold at Stone Quarry Hill Art Park. It is easy to buy, but I prepared it myself with some plywood and nails. I designed a bird house like box in order to fit the location in the Art Park.
Measure the size and cut the materials.
Build the basic structure.
It’s gonna be look like this.
Sand it down.
Spray brown paint.
After this step, I sprayed more brownish, attached the door with a hinge and Stevenson screen on both sides. The box will hold the electric parts such as Arduino board with MP3 Player Shield, an original circuit for amplified the sound with synchronized blinking LED, and the power supply. It will be hung a tree with a big Zip-Tie.
