Using IFTTT we can send a trigger signal through the cloudBit at a scheduled time every day. This signal goes down both wires of the Split Module. On one end it causes the servo to pull the pin that is holding up a counterweight. When the pin is pulled, the weight falls, pulling the cord that opens the curtains. On the other end of the split, the trigger signal causes the mp3 players to start playing a sound file. This file is played through the speaker, which is hooked up to an old radio horn for amplification and general awesomeness.
Cut out the wooden panels you will need to assemble the shelf for the circuit and speaker. The image above will show you what you need to cut. If you want a print out template, we've included a PDF you can download below.
Step 2: Start Gluing
Glue the panels A, B, and C together as shown in the assembly graphic. When you add the shaft collar, make sure that the set screw is facing the back of the shelf. A couple of pieces of double sided tape will help keep the shaft collar in place while you are gluing.
Step 3: Glue Together the Servo Mount
Next, glue two of the D strips together to create a .5" x .5" x 2.75" block. Repeat this with the other two D strips. When they are both dry, glue them to the back of panel A as shown in the assembly diagram. The space between the two pieces should be the width of the servo.
