Single axis self-balancing reaction wheel inverted pendulum. This thing is inherently unstable and a common challenge in control theory. The mechanical structure is built using only Lego parts. Motor is also Lego. Angle sensor and electronics are not Lego.
It won’t win any awards for presentation, but this Python-driven automation solution gets you your cup of joe in the morning regardless.
Pseudonymous maker “petertree” has built a coffee maker — “2x more expensive and messy than one you can get on Amazon,” he notes — powered by a smart plug, a peristaltic pump, and a Raspberry Pi.
We Finally Have a New Retroflag Handheld! In this video we take look at the all-new RetroFlag GPi Case 2, A GameBoy DMG Inspired Handheld emulation Console Powered by Raspberry Pi CM4! With an upgraded 3” 640×480 IPS Display and the option of an HDMI Dock this little retro handheld has turned out to be really awesome and it can play PSP, Dreamcast, PS1, and even N64 Games using RecalBox, RetroPie, or even Batocera.
An anonymous maker decided that the 4GB of RAM in their Raspberry Pi 400 was too limiting — so, armed with a hot-air rework station, upgraded it to a more capacious 8GB.
Pseudonymous maker “hoarsecheerleader” has turned a Raspberry Pi 4 into an in-car retro gaming system — for backseat passengers only of course — using an all-in-one display case and a 12V power supply.
The Raspberry Pi has long been popular for retro-gaming projects, thanks to a combination of low cost yet impressive performance in a small package. It’s also the heart of more than a few in-car entertainment upgrades — but hoarsecheerleader’s project combines the two.
In this video I show you how to overclock the new Raspberry Pi Zero 2 W! I go over two different ways of overclocking first all on the Pi Zero 2 and second from a different PC. I recommend a heatsink of the Flirc case for the Pi Zero 2 W when overclocking but this defiantly helps out with performance! The Stock CPU speed on the Raspberry Pi Zero 2 W is 1.0GHz but we can easily overclock to 1.3GHz.
This clever — and non-destructive — upgrade adds digital capabilities, including streaming, to a classic of home cinema.
Pseudonymous maker “befinitiv” has once again designed a digital upgrade for a classic film camera, this time refreshing an old Super 8 cine film camera with a Raspberry Pi Zero W.
“Nowadays [Super 8 cameras] are almost unusable right now, because these cartridges are really hard to get,” befinitiv explains in the project’s video, brought to our attention by Adafruit. “You can find them still, here and there, but shooting one roll of film will cost you roughly €60 (around $70) — and this is €60 euros for three minutes worth of poor quality video.”
Just as small. Five times as fast.
At the heart of Raspberry Pi Zero 2 W is RP3A0, a custom-built system-in-package designed by Raspberry Pi in the UK. With a quad-core 64-bit ARM Cortex-A53 processor clocked at 1GHz and 512MB of SDRAM, Zero 2 is up to five times as fast as the original Raspberry Pi Zero.
Wireless LAN is built in to a shielded enclosure with improved RF compliance, giving you more flexibility when designing with Raspberry Pi Zero 2 W.
All in the same tiny 65mm × 30mm form factor.
After replacing the internals of an original 4th gen iPod with a Raspberry Pi Zero W, it now supports modern features and a bigger battery.
The original iPod was what many consider to be the product that launched Apple into the realm of pocketable consumer technology and acted as a precursor to the now ubiquitous iPhone lineup. In recent times, the nearly two decades-old technology within the iPod is very outdated, but rather than throwing his old one out, one user who goes by production on Hackaday.io decided to upgrade it with some new internals while still being able to control everything with the original buttons and capacitive front wheel.
In this Raspberry Pi boot from USB guide, we will be showing you how it is possible to boot your chosen operating system from a USB storage device instead of the standard SD card.
We will walk you through the steps required to activate the USB boot mode in the one-time programmable (OTP) memory. You will need a newer Raspberry Pi to complete this tutorial correctly (see below).
