Mini Tv That Pops Up on Your Bed

Have you ever wanted a TV by your bed so you could watch? This little TV pops up whenever you push a button. You can put it anywhere, but it works best in bed. It has to be behind something to pop up.

Supplies

Making the Circuit

Attach wires from the air motor to the switch to the battery. Turn it on, and see if the air motor is on. Attach raspberry pi to screen. Add HDMI connection and plug in a battery. The screen should turn on. Make a box for the screen, raspberry pi, and the battery. Take two 20 mL syringes and glue the bottom of the two the bottom right and the bottom left of the miniature tv. Attach a tube to the syringes. Put the ends of the two tubes into the wye tube fittings. Attach a tube from the last remaining hole to the air motor. If you turn it on it should quickly rise. Once fully risen, turn off and push down. Almost done! Good job, you completed the circuit, the tv, and the tubes! Next step you will make the base and attach it to your bed, or another place.

Making the Base

Go to your bed with your machine. Glue the switch on the frame of the bed. Put the tv right below where you can see. Glue the syringes right under that place. Once you push the button, the tv will pop-up. Turn on your battery, open up Netflix or Disney, and your on the road. Have fun! Once you are done, push the screen down.
