A Raspberry Pi Pico powers this amazing replica of the Fallout T-45 Power helmet

Key insights

  • A child-friendly Fallout T-45 Power helmet powered by Raspberry Pi impresses with sensors and speakers.
  • The helmet has features such as an internal temperature sensor, 5V fan, LED lamp, microphone and more.
  • Plans for an improved second version include a voice changer microphone, building on already impressive features.



I don't know about you, but I don't put much effort into costumes. If I can do the basics without much effort, then I think it's good enough. So imagine my surprise when I saw that someone had built their kid a full-fledged Fallout T-45 power helmet for Halloween, complete with sensors and speakers and all powered by a Raspberry Pi Pico. Well, now I have to improve my costume, don't I?

Raspberry Pi 5 review: The holy grail of DIY projects just got better (and rarer).

The Raspberry Pi 5 is one of the most powerful consumer SBCs on the market. Unfortunately, due to limited inventory, it will be difficult to find one.

This T-45 Power Helmet from Fallout runs on a Raspberry Pi and covers pretty much every base


In a post on the Raspberry Pi subreddit, user Grimdaria shared the amazing project they created for their child. Grimdaria praises her successes at every turn, calling both the wiring and paint “shitty,” but take a look at this list of features and tell me what's “shitty” about it:

  • Pi PICO microcontroller
  • External blue LED indicates PICO is ready for use
  • Internal temperature sensor
  • 5V fans that activate depending on the internal temperature
  • 12-LED NeoPixel for main lamp
  • External stereo microphones that feed into stereo headphones (can hear things outside the helmet)
  • Two external buttons and an external potentiometer to control light/sound volume
  • Internal OLED screen that shows the status of all electronic devices (lights on/off, fans on/off, fan speed, temperature, headphone volume)


Yes, this is an internal temperature monitor that detects when the helmet becomes too stuffy and activates fans to cool the wearer down. I don't think even Fallout power armor has this luxury.

Grimdaria didn't have enough time to add a microphone connected to a voice changer for extra oomph, but they plan to make a second helmet where they correct all the “mistakes” they made in the first iteration. We're looking forward to the second model, especially when they downplayed this one so much. And if you want even more DIY wearables, check out these AR glasses someone made with a Pi.
