IT Crowd Internet Black Box

If you’re a fan of The IT Crowd, you’ve probably fantasized about building The Internet Black Box. You may have also dreamed about playing the same trick on your co-workers as Roy and Moss play on Jen. The good news is, now you can. If you’re not a fan of The IT Crowd GTFO! If you have no idea what The IT Crowd is, do yourself a favor and go watch it right now.

At DIY Nerds we decided The Internet would be our triumphant return. So here it is, our awesome replica of “The Internet” prop from The IT Crowd. The IT Crowd was a geeky British sitcom on Channel 4. The Internet was a mysterious black box and prank in Season 3, Episode 4 of The IT Crowd. Our replica doesn’t come with an on/off switch, because that’s just crazytalk, nobody turns off the interwebs. You’re more than welcome to add an on/off switch to your build though, or you can always just buy a ready-made replica (Etsy, $45).

How-To Build the Internet Black Box Summary

First we went to find the center of the top of our black project box.  There are a couple ways to do this, but the laziest easiest way to do it is to put two strips of masking tape going across the top.  The first strip should be centered and going vertical, while the other is centered and going horizontal. Feel free to eyeball it. The masking tape also provides a clean and safe way of drilling a hole through the top.

After you’ve applied the masking tape and it is centered as best you can.  We want to use our 1/4″ drill bit and drill a hole directly in the middle. (Your drill bit may need to be different depending on the size of your Blinking Red LED).

Lastly, we twist the red wire from our Blinking Red LED to our red wire on the AAA Battery Holder. We then repeat the same step and twist the black wires together from the Blinking Red LED to the AAA Battery Holder.  The wires will now need a couple small strips of electrical tape. (Alternatively, you can solder the wires together and use some heat shrink tubing for a cleaner look)

Plug in your batteries, ensure the light is blinking or turned on, and screw in the enclosure with your phillips screwdriver.

  1. Take two strips of masking tape and apply them to the top of the black project box to form an “X” and identify the center of the top as seen below.

    Don’t forget to tighten the nut and secure the LED
  4. Connect the red wires from the LED to the AAA battery holder by twisting them together. Then connect the black wires the same way. Wrap some electrical tape around the ends to secure them

  5. Finally, secure the battery holder to the inside of the project box and then screw closed the bottom plate

    That’s all it takes and luckily for you, you can have now the The Internet for your own office. While ours doesn’t have an on/off switch, the batteries should last forever a long time to only power a single LED. Make sure you take pictures and include them in the comments below. We can’t wait to see you one-up us and what kind of mods you include in your project.
