Hackaday ☛ The Lowest-Effort Way Yet To Make 3D Printed Lenses Clear
This technique shared by [Andy Kong] is for 3D printed lenses, but would probably be worth a shot for any resin prints that need to be made nice and clear. The link to his post on X is here, but we’ll summarize below.

Arduino ☛ Build an ePaper weather display and message board using Arduino Cloud
This device shows current weather information and custom messages on a 2.9” Pervasive Displays EPDK-Matter Development Kit screen. Though that was designed for use with the Arduino Nano Matter, is also works with others, including the Nano ESP32 that Vilo chose for this project. Like all e-paper displays, it only consumes power when refreshing the screen. And the adapter makes it easy to connect to the Arduino board.

Raspberry Pi ☛ Cardiography signal measuring device built on Raspberry Pi Pico W
And yet he was clear from the start that he wasn’t going to create a medical device. Instead, the ultimate aim was to take readings and conduct experiments to discover an optimal algorithm for measuring blood pressure. “The whole area of blood pressure monitors was a curiosity for me and I wanted to demystify it a bit and generally have a platform which other people can experiment with,” he explains. “So I created a setup that can be used for experimenting with new methods of analysing cardiography signals.”

Tom's Hardware ☛ Raspberry Pi Pico Spacewar controller brings vintage space combat to the 21st century
If there's one thing that all Raspberry Pi are good for, it's emulating classic games but this project doesn't emulate the DEC PDP-1 minicomputer, instead it emulates the controllers. Today we're delighted to share with you a cool Pico-powered controller system designed to control an emulator for the 1962 game Spacewar! developed for the PDP-1.

Tom's Hardware ☛ Adafruit's Fruit Jam is a Raspberry Pi Pico 2 powered, credit card sized computer
One of the coolest things about the Raspberry Pi is all of the cool third-party boards that get made by the community and professional companies like Adafruit. Today we're excited to share a cool design put together by the team over at Adafruit featuring the Raspberry Pi Pico 2's RP2350B microprocessor. In a blog post uploaded earlier this week, we get a close look at a new board design called the Fruit Jam RP2350B.
