Pseudonymous steampunk fan and maker “Smurfy_CH,” hereafter merely “Smurfy,” has designed a tool which remembers your passwords for you till you want them then varieties them out — all whereas wanting like one thing a Victorian incarnation of Physician Who may pull out of his pocket.
“A number of months in the past I stumbled upon the Raspberry Pi Pico, a small and inexpensive microchip that’s able to emulating a USB keyboard,” Smurfy explains of the mission’s origins. “So I got here up with the thought, to place my passwords on a micro SD card, hooked as much as the Pico with a small show. With a choosing choice to ship the login-string straight to the pc. To spice it up, I gave it a steampunk look with the assistance of my 3D printer.”
The 3D-printed steampunk housing, which features a ornamental vacuum tube at one finish with an RGB LED offering a glow, homes the Raspberry Pi Pico microcontroller board, a compact OLED show panel, and a microSD card reader.
It is this card which shops the passwords, to be picked utilizing a rotary encoder — and whereas the passwords themselves are saved in plain textual content on the cardboard, Smurfy factors out that they are protected from assault by way of the host machine by dint of solely being accessible from the Raspberry Pi Pico.

Utilizing the password protected is straightforward: use the rotary encoder to choose from the listing of saved passwords and push its button: the Raspberry Pi Pico acts as a keyboard and kinds them in to any system which helps USB Human Interface Units (HIDs). The RGB LED behind the vacuum tube gives a standing report: inexperienced means it is able to enter information right into a subject, crimson means information is being despatched, and blue means it is ready for the consumer to push a button.
A full information to constructing the system, together with 3D-printable STL information, is out there on Smurfy’s Instructables web page; observe, nevertheless, that the present model of the software is pre-configured to make use of a German keyboard format.
