In this project, you’ll use a Feather RP2040 USB Host to listen for a specific button combination from your attached gamepad to trigger “turbo mode” aka rapidly sending A button presses. Otherwise, the Feather acts as a passthrough for your controller, sending all of your gamepad inputs as pressed.

Don Wilcher uses a Raspberry Pi Pico to build an adjustable clock with an LED display then integrate the clock with a vintage Radio Shack Science Fair Microcomputer Trainer programmed to function as a 7-bit binary counter.
Long before the Heathkit 6800 microcomputer learning system, the Arduino Uno, or the Basic Stamp, there was Radio Shack’s Science Fair Microcomputer Trainer kit. Introduced in 1985, this easy-to-program kit was intended to teach users how microcomputers worked.
In this project article, we’ll upgrade this vintage microcomputer by building and adding an adjustable Raspberry Pi Pico clock with an LED display. After assembling the hardware, we’ll program the trainer to operate as a 7-bit binary counter. Before any of that, though, let’s spend some time learning about the trainer’s features—and, in particular, about the TMS1100 microcontroller at its core.
Don adds a Raspberry Pi Pico programmed in MicroPython, making an adjustable digital clock.

PiMyLifeUp shares how to turn your Raspberry Pi into a Wi-Fi router using Pi-Fi.
PiFi is a distribution that makes setting up your Raspberry Pi as a speedy OpenWrt-based Wi-Fi router significantly easier. It is definitely a project you will want to consider using if you want a super portable travel router.
OpenWrt, for those who do not know, is an open-source operating system with a focus on network routing. It has become a popular choice for anyone wanting to set up their very own router. PiFi utilizes its own customized version with improvements to work better on the Raspberry Pi and be controllable through their app.

With some sensors, servos and of course a Raspberry Pi, you can create some spooky effects. Hack into store bought props to induce the ultimate chills.
NetworkChuck set up a haunted house to scare his daughters. The power of the Pi lets you set the level of scares. He goes through 1,2,3….and 4!
This is my Raspberry Pi Haunted house. In this video, I’m going to show you how to program your Raspberry Pi in Python to scare EVERYONE for Halloween. For a solid basic scare, all you’ll need is a Raspberry Pi and some speakers. For more advanced users….you’re going to have some fun.

For most a walkman is a hopelessly dated piece of personal musical equipment, fit for the technological cemetery. But makers no gadget is without its use-value or inspirational power. The WALKPi takes its inspiration from the dearly departed Walkman, re-made DIY-style for makers Here’s more from via instructables:
Similar to a traditional walkman, WalkPi is an audio player setup that plays audio files stored on an SD card by pairing a Raspberry Pi Pico with the DFMini Player. It has an SSD1306 OLED screen, an interactive menu with various buttons for selecting tracks, volume controls, and additional functions.
…
The Raspberry Pi Pico, the project’s brain, is linked to the DF Mini Player, a compact, inexpensive MP3 module that has a simplified output directly to the speaker.
Check out our Raspberry Pi Face Recognition Treasure Box learn guide in the adafruit learning system! Tony DiCola shared this video on Youtube!
Face recognition is an exciting field of computer vision with many possible applications to hardware and devices. Using embedded platforms like the Raspberry Pi and open source computer vision libraries like OpenCV, you can now add face recognition to your own maker projects! In this project I’ll show you how to build a treasure box which unlocks itself using face recognition running on a Raspberry Pi.
From the GitHub release page:
This is CircuitPython 9.2.0-beta.1, a beta release for 9.2.0. It has known bugs that wil be fixed before the final release of 9.2.0.
WARNING for nRF52 boards only: If your board has an nRF52 UF2 bootloader whose version is before 0.6.1, you will not be able to load CircuitPython 8.2.0 and later, due to increased size of the firmware. See these instructions for updating your bootloader.
