Raspberry Pi is an incredibly versatile computer that delivers much more power and functionality than its small stature suggests. Now, with ten years of solid development behind it, Raspberry Pi computers and Raspberry Pi OS are packed with activity. Hidden in amongst all the hardware and software are some real gems of tricks that you can use to learn more about computing, make better projects, and get far more out of Raspberry Pi than you ever thought possible. In this month's issue of The MagPi, we unearth hidden hacks and handy tricks that every talented Raspberry Pi owner should know. Here is just a section of our hidden hacks bumper feature: Raspberry Pi Hardware Hacks.

In the Northern hemisphere, summer is about to hit us full bore. While we love the season, we do dislike lawn maintenance. Apparently, so does [salmec] who developed the Mowerino around an Arduino Mega 2560 board. As you might expect, the robot uses sharp blades so, you probably want to be careful. There are sensors that allow the machine to self-navigate or you can control it via Bluetooth. This is one of those things that seems easy until you try to actually do it. Nylon trimmer string is probably safer, but it breaks and it is hard to keep it cutting. Blades are more robust but also riskier to things like rocks, fingers, and pets.

Sodium chloride, or table salt, has a cubic crystal structure. But the salt we use for cooking normally looks more like sand. Indeed, table salt is often used in kids’ experiments to demonstrate crystallization. It’s a simple activity, but the results are disappointing. Many tutorials online make it look far easier than it actually is.   This is because sodium chloride crystals are very sensitive. Temperature differences cause imperfections. It also crystallizes easily on dust particles, growing misshapen clusters, hopper crystals and dry crust. However, being as stubborn as these crystals, I have tried multiple times to grow them over the past 3 years. Eventually, I discovered a technique to grow large, high quality sodium chloride crystals, and I want to share it with you.

  If there's one thing I've learned, it's never doubt the ingenuity of a Raspberry Pi owner. These credit card sized computers have been made to do all sorts of things from being a baller retro gaming machine, to a garish PC gaming handheld.  But if you're wanting something a little weirder to serve up with your Pi, maybe have a look at this adorable laptop -like machine. Daniel Norris (via Liliputing) is the madman behind the Chonky Palmtop, a tiny PC with an included fold out split keyboard. This thick little beasty has a swish retro 3D printed grey box, which opens up to reveal the 7 inch touchscreen display and keyboard setup.  Read The Chonky Palmtop is one of the cutest DIY Pi machines yet via pcgamer An interesting link found among my daily reading

Cat Ears Prototype 2 Test Run from Jazz DiMauro on Vimeo . "I built mind-controlled ears as a way to learn how to build my own arduino-based designs," writes Jazz DiMauro. "Challenges included cable management and designing custom servo hardware to attach to the asymmetrical EEG headset." See also Jazz's Witch Lights. Sketches and plans galore!
