This is a simple Instructable to help you make a simple dream catcher alarm.

You can check out more at my website dreamcatcherproject.net

You can see my youtube video about how it works here.

You can see a video of it in action here.

The guts (electronics minus the case) can be seen here.

Step 1: Materials.

Here is a list of what we need to make the project.

+ wire

+ wire cutters/strippers

+ heat shrink tubing

+ AAA battery holder, AAA battery

+ an ON/OFF switch

+ a button - normally closed (NC), opens when pressed.

+ soldering iron, solder

+ hot glue gun

+ 1.5" PVC pipe cap, or anything to house the electronics (I use some 3/4" PVC and a cap in this demo)

+ DC 5V continuous sound buzzer

Step 2: Preparing the Case

First we will prepare the case so that when we insert the electronics we will know that everything will fit properly.

I cut a little notch in the bottom so that the switch will sit flush with the edge.

Step 3: Wiring the Electronics

The wiring is pretty simple. Just wire the switch, the button, the buzzer and the batter in series.

There are a few things to be mindful of as you solder the components and the wires. The switch that I used required soldering the center pin and one of the outside pins. I made sure to put heat shrink on the wires before soldering them to the components so that I could cover the leads after they were soldered.

Also, you need to make sure that the button is wired in the normally closed configuration. One way is normally closed (NC), the other is normally open (NO), you want the NC configuration.

Lastly, one side of the buzzer is labeled with a "+". You want the wire connected to the + pin to trace back to the plus side of the battery, which is normally red. The other pin goes to ground, "-", GND, which is normally black. You can test your circuit by touching the wires to the pins of the buzzer. If the buzzer sounds, everything is wired correctly and is ready to solder. If it doesn't buzz, double check your connections.

Step 4: Put It in the Case

Now we are ready to put it into the case.

I drilled a hole in the end of the PVC cap to put the button through. I pulled the rest of the electronics through the PVC pipe.

I left the wire kind of long to make sure that I had enough slack, but I left too much and it was difficult to stuff them all in, but it worked. Once I got everything in the case, I hot glued the switch into the notch that I cut at the beginning.
