Maker Lorraine wanted to motivate her family to up that step count, so she set them the goal of running the distance to the Moon. Totally do-able. She created a Raspberry Pi Pico W-powered motivational tool to let them see their progress and drag them through those last tough hundred thousand miles.

There are some improvements that I might implement to a revision of this board. The USB cables connecting the external SSD-s seem to be just small enough to be routable behind the pegboard. Other cables that are visible can probably be hidden on the other side as well, giving the setup a much cleaner look.

This is the newest iteration of a project that Cogley first started a few years ago. It is robotic hand meant to mimic a human hand as much as possible. Human fingers do not contain muscles. Instead, muscles in the forearms and palms pull on tendons to move the fingers. Cogley’s bionic hand works in a similar manner by using servo motors in the forearm to pull on cables that actuate the fingers. An Arduino UNO Rev3 moves the servos according to commands from a PC, but Cogley needed a way to streamline those commands.

With the Librem 5 just hitting shipping parity and Purism holding stock for new purchases, it was time for an updated review of the tremendous progress our team has made with PureOS for the Librem 5 and Liberty Phone with Made in USA Electronics. Here we will talk about the good, bad, and lasting effects of PureOS on the Liberty Phone and Librem 5.
Both the Librem 5 and Liberty Phone were a giant gamble that paid off in a big way. Prior to the Librem 5, nearly every new phone produced used the software stack from Android or iOS, both of which are fundamentally flawed around data protection and proper transparent fully released source code. Instead of using this problematic base and adopting apps that monetize your data, or where the source code is not released, or worse… both of those. We chose the much harder but proper path and built an Operating System, PureOS, using only free software thereby avoiding data collection entirely, advancing fully free software, and bonus we invented true convergence within PureOS which is a non-Android Linux OS. With PureOS, you get a full Linux Desktop on everything from servers to phones. We don’t collect user data nor provide avenues to easily incorporate ads into our ecosystem. Resulting in a pure experience free of nagging apps and unalterable defaults. The Librem 5 and Liberty Phone running PureOS do not spy on you, giving you peace of mind that you are fully protected from the hardware all the way to the apps.
On the Liberty phone and Librem 5 the Linux kernel is kept up to date by Purism and its many investments in upstream, it needs a shrinking number of alterations from the main branch because of these advancements. This keeps kernel features up to date and makes it easy to port alternative OSs to the Librem 5 or Liberty Phone. Congratulations are in order for our Linux kernel team.

At its core, the ESP32 chip is not much more than an integrated circuit, a huge mass of transistors sealed inside an epoxy resin package with some leads. Of course, most of us won’t buy discrete ESP32 chips with no support circuitry since it’s typically easier and often not that much more expensive to get them paired with development boards of some type for easy access to things like USB and GPIO. But these tiny chips need little in the way of support to get up and running as [Paul] demonstrates with this tiny ESP32 board.
