In the original Animal Crossing from 2001, players are able to interact with a huge cast of quirky characters, all with different interests and personalities. But after you’ve played the game for awhile, the scripted interactions can become a bit monotonous. Seeing an opportunity to improve the experience, [josh] decided to put a Large Language […]
Perpetual motion devices are either a gag, a scam, or as in the case of this particular toy that [Big Clive] bought on AliExpress, a rather fascinating demonstration of a contact-free inductive sensor combined with a pulsed magnet boost for the metal ball. A cool part about the device is that it comes with a […]
The PIXO Aspire is a roughly $35 USD vape that can almost play DOOM, with [Aaron Christophel] finding that the only thing that realistically stops it from doing so is that the Cortex-M4-based Puya PY32F403XC MCU only has 64 kB of SRAM. CPU-wise it would be more than capable, with a roomy 16 MB of […]
For the past years people have been collecting disposable vapes primarily for their lithium-ion batteries, but as these disposable vapes have begun to incorporate more elaborate electronics, these too have become an interesting target for reusability. To prove the point of how capable these electronics have become, [BogdanTheGeek] decided to turn one of these vapes […]
Handling large volumes of physical media can be a bit of a chore, whether it’s about duplication or archiving. Fortunately this is a perfect excuse for building robotic contraptions, with the robots for handling optical media being both fascinating and mildly frustrating. When [Shelby Jueden] of Tech Tangents fame was looking at using these optical […]
As is regrettably typical in the cordless tool world, Milwaukee’s M18 batteries are highly proprietary. Consequently, this makes them a welcome target for reverse-engineering of their interfaces and protocols. Most recently the full diagnostic command set for M18 battery packs were reverse-engineered by [Martin Jansson] and others, allowing anyone to check useful things like individual […]
The PAX D177 PoS terminal helpfully tells you which tamper points got triggered. (Credit: Lucas Teske) These days Points of Sale (PoS) usually include a digital payment terminal of some description, some of which are positively small, such as the Mini PoS terminals that PAX sells. Of course, since it has a CPU and a […]
The patient hooked up for some reverse-engineering. (Credit: Caralynx, Twitter) Released in July of 2025, the Tamagotchi Paradise may look somewhat like the late 90s toy that terrorized parents and teachers alike for years, but it’s significantly more complex and powerful hardware-wise. This has led many to dig into its ARM Cortex-M3-powered guts, including [Yukai […]
One of the great things about sharing hacks is that sometimes one person’s work inspires someone else to take it even further. A case in point is [Ivor]’s colorimeter hacking (parts two and three), which started with some relatively simple request spoofing to install non-stock firmware, and expanded from there until he had complete control […]
Your kid has a toy remote control fire truck. You have an RTL SDR. See where this is going? [Jacob] couldn’t resist tearing into the why and how of the truck’s remote control protocol. The entire process began with a basic GNU Radio setup to determine the exact frequency of the signal. Then a little […]
