Picture of Punch Activated Mario Question Block Lamp

The Super Mario games were my childhood. I've always wanted to have some of the props in the games, and now that I have the tools to do it, I decided to start making them. The first up of that on my list is the Question Block. I managed to make the question block so that when you punch it, it either turns on or off. When it is triggered on or off it plays one of four sound effects from Super Mario Bros. It is designed to screw into a lightbulb socket and hang from the ceiling. If you wanted to hang it differently that can be done easily, all that has to be done is that it needs a 12V power supply routed to wherever you mount it.

Step 1: Materials and Tools

Picture of Materials and Tools


  • Yellow PLA filament
  • White PLA filament
  • 12V White LED Strip (5m roll)
  • Arduino Pro Mini (ATMEGA328P 5V 16Mhz variant)
  • SW420 Vibration Sensor
  • 2N2222 tranistors
  • TIP120 Darlington Transistor
  • DC-DC Step-down converter (for the 12V to the 5V the arduino requires)
  • 0.5W 8-Ohm speaker
  • 12V 1A Power Supply
  • 2 Core Sheathed Wire
  • Misc. Wire
  • M3 screws and nuts


  • 3D printer (preferably dual color, but single color will work it's just harder)
  • Wire Cutters
  • Wire Strippers
  • Super Glue
  • Philips Screwdriver
  • Utility Knife
  • Soldering Iron
  • 60/40 Lead Solder Rosin Cored
  • FTDI Programmer and Mini-B USB Cable
  • Hot Glue Gun

First, this was an excellent project! I'm building it for my nephew's birthday, and he's really into Mario so it should be a solid win. I've got a bit of an issue though, I have all of the electronics assembled and it works to turn the light on / off when tapped. The sound is there but it can only be faintly heard when holding the speaker up to my ear. What controls the volume / is there a way to make it louder?

Thanks again for this one, it's going to make a perfect present!

After leaving it plugged in for a while and playing with the lights...I noted that both the speaker and the 2N2222 transistor get quite hot. I tested the voltage regulator and am sure that it is putting out 5V (and haven't crossed my power wires). Do you think this is connected to the sound problem?

Did a bit of research into the 2N2222 and apparently they have a history of not conforming to a standard layout. Tried the "diode" test to see which leg was which and that didn't help. Trial and error with a test board and alligator clips solved it. The wiring on the transistor needed changing. It works GREAT now!
Thanks again for this one, can't wait to see what else you have in store!
Great Job!!!!!!! You can powered by inner battery, voltage regulator lm7805, battery 3.7v 1200mAh etc,

I was tempted to do that but I didnt want to have to deal with recharging the lamp all the time and taking it down to plug it in. But you're right it could have been easily done

I love this idea. Do you have anymore on this concept?
Zachary Goode (author)  JessicaH2887 months ago
I'm not entirely sure as to what you are asking. Would you mind clarifying what you mean by more on this concept?
Sorry I meant more Super Mario Bros. Concepts.
Though I don't know how it could be done but I always like the stairs at the end of the levels.

The only other thing I have from super mario bros currently is a thwomp model I designed a while ago.

Im not sure yet what i'm going to make next, but I am open to suggestions.

How fun is this? Nice work!

It's really fun to just walk and punch it. It's really satisfying to hit it and get the coin sound effect. I have it in the hallway probably about half a foot above my head (so about 6 - 6 1/2 feet.)
Very fun light!
