German designer Kevin Noki has introduced the ADHD ONE, a 3D-printed handheld device designed to help users reduce smartphone usage. The device mimics the aesthetic of early mobile phones, featuring a bulky chassis, a top-mounted antenna, a 19-key physical keypad, and a small OLED display.
The ADHD ONE lacks independent cellular connectivity. Instead, it functions as a Bluetooth peripheral that pairs with an iPhone. Once connected, the device uses the hands-free protocol to allow users to make and receive calls while their primary smartphone remains stored away.
The device is powered by a Raspberry Pi Pico and utilizes an FSC-BT1026C Bluetooth module based on the Qualcomm QCC3024 chip. It includes a microphone, a speaker, a rechargeable lithium battery, and charging circuitry. The enclosure is designed in Autodesk Fusion.
Noki is selling the project files for €29.99. The package includes 3D-printable STL files, firmware, PCB production files, a bill of materials, and an assembly guide. Users are responsible for printing the housing, sourcing the components, and assembling the unit.
