Introduction: MakeyMakey 'Selfie AttendeeHub'
As a teacher in middle school, I needed a way to take attendance quickly. Having this set up near the door of my classroom will be a quick way for students to step up and have a photo taken to show me that they were in the room that day. Using the chromebook, will easily allow me to add the photos to Google drive according to date.
This project will use the foot pad as a trigger to snap a photo on a chromebook when attached to the MakeyMakey.
Your first step will be to assemble your supplies and find material appropriate for the type of foot pad trigger that you want. I used 2 pieces of 12 x 12 pressed wood. This material is fairly lightweight, durable and a bit flexible.
- 2 pieces 12 x 12 inch pressed wood (this could possibly be cardboard or other sturdy material)
- 2 pieces 4-6 foot of telephone wire
- Duct tape
- Aluminum Foil
- Electrical tape
Step 1: Getting the Inside Ready
After having my 2 pieces of wood together, I taped heavy duty aluminum foil to what would be the inside of the foot pad. I used strong duct tape and large pieces of foil so that there would be lots of room for the pieces to connect when someone steps onto the footpad.
Step 2: Appropriate Wire
For this project, something longer and stronger than the alligator clips was going to be necessary for durability of being stepped on several times a day. I purchased 6 feet of what I refer to as 'telephone' type wire - it is strong copper wire with a coating on it. You will need to remove about 2 inches of the coating off of each end of the wire.
Step 3: Attach the Wire
Using electrical tape, an end of the wire was attached to each board with the wire coming in contact with the aluminum foil. The other two ends of the wire were attached to the MakeyMakey - one to earth to ground it, and one to the button for click. I simply wrapped the wire through the holes and twisted it so that it would stay secure.
Step 4: Add Fun Foam
Going the length of 2 opposite sides of the board, I attached about a 2 inch strip of the fun foam using duct tape. The first that I added was extra thick but it still was not enough to hold the boards apart. I had to adjust this part a few times to get the right thickness so that my camera would not continue to snap because of the aluminum foil touching. After securing the foam, I was then able to put the two pieces together where foil sides were facing each other. Everything was secured with duct tape and I was ready to test my project.
Step 5: Let the Fun Begin
As you can see in the video, this set up works very well and photos can be taken fairly quickly. I may even see about using this at a school dance for when the students want to take selfies. Having the screen in front of them, helps them know when they are ready and positioned correctly.
Hope this helps with your next photo project.
