Bend the wire over so it is touching the soldered header pin. With the soldered side up, insert the blue wire of the display connector from the bottom up as in the photo. Pull the perfboard and header out of the breadboard so we can solder the other wires. Turn on your soldering iron and let it heat up for a minute. With the copper side up, insert the second long row of perfboard holes onto the header pins like in the photo. Insert the long end of the pins into a breadboard. Snap off a section of 13 pins from your header. If you don't have heat shrink electrical tape can work in a pinch. Shrink it and do the same for the other soldered connection. Now add a piece of heat shrink over one wire to cover the connection you just soldered. Your switch and the two yellow wires should now be soldered like the fourth photo. Be very careful when soldering as the iron is very hot and use plenty of ventilation. Now soldering the wire on and the do the same for the second wire. It doesn't matter which wire goes to which lead. Insert one wire into the hole on the lead from the switch and clamp it down with the pliers. Start by taking your pliers and bending both wires like in the second photo. We need to solder the two yellow wires into the switch. Now plug the Arduino back in and the countdown should begin. Red goes to 5V, black goes to GND, Yellow goes to analog pin 4 and the blue wire goes to analog pin 5. Make sure your Arduino is unplugged and insert the 4 connector wires into the appropriate pins. The yellow wire is for SDA and the blue wire is for SCL. Make sure the red wire goes to VCC and the black wire goes to GND. Insert the connector into the back of the 4 digit display. If you haven't already put the display together follow the directions on Adafruit now. Just be careful no to touch the soldering iron to the heat shrink. You can use a hairdryer or your soldering iron to shrink it. Now add a small piece of heat shrink to the yellow and red wires to make sure you don't get a short later. Now you should have a connector like the third photo. Then insert the yellow wire and the blue wire should be on the other end. Next to the red wire insert a black wire. What you have should now look like the second photo. Give it a light pull and it should not come out. Put the flat side of the crimping up and it should click into place. Take one of the red pre crimped wires and insert the pre crimped flat end into the left most hole of the connector with the connector holes facing up. Now set this aside and let the glue dry.įirst lets put together the connector for the display. If the display doesn't quite fit you can always make the hole larger buy carefully cutting with the X-Acto knife. Start with the front and make sure the hole for the display lines up correctly. Once this is done go ahead and glue the original printout over the cardboard. Now tape this in place and glue the tab from the top piece to the back of the front panel. Apply glue to the side panel tab and bend the top panel over to attach it's underside to the tab. Now we need to tape and glue it together. The fourth photo shows the cardboard cutout bent mostly into shape. After that, bend the two tabs 90 degrees. Then bend the left and then the top piece. First bend the right side as shown in the second photo. Now set the printed cutout aside for later and work on the cardboard. Once you have traced it onto the cardboard box cut it out, check that the 4 digit display fits into the rectangular hole. Here we used a cereal box from TraderJoe's because the cardboard was nice and thin. Trace what you just cut out onto your cardboard box. We have included a Photoshop file and an outline file if you want to change the look of the TV, but if you just want to go ahead use the TV.pdf file.Ĭut it out and don't forget the switch hole on the side. First print out your tv box using the file here called TV.pdf.
