Collaborate Disseminate
The renowned inventor of useless robots [Simone Giertz] has outdone herself this time. She, along with a team of engineers featuring [Rich Rebuilds], [Laura Kampf], and [Marcos Ramirez], recently decided to convert a Tesla into a pickup truck, and make a video along the way, all while salvaging what remains …read more
In a world with finite storage and an infinite need for more storage space, data compression becomes a very necessary problem. Several algorithms for data compression may be more familiar – Huffman coding, LZW compression – and some a bit more arcane.
[Labunsky] decided to put to use his knowledge …read more
Does anyone remember the Black Hat BCard hack in 2018? This hack has been documented extensively, most notoriously by [NinjaStyle] in his original blog post revealing the circumstances around discovering the vulnerability. The breach ended up revealing the names, email addresses, phone numbers, and personal details of every single conference …read more

For home use IoT systems, getting sensor data from tons of physical locations centralized to a single Raspberry Pi can be a difficult job, especially when considering the power consumption that’s necessary for doing it all over WiFi. When you’re using an ESP8266, for instance, swapping out batteries and accounting …read more

The purpose of Geometer becomes apparent when you realize its simplicity: [David Troetschel]’s project is to create an easily understandable design tool that encourages goal-oriented design. The kit comes with physical components and digital counterparts that can be combined in a modular way. They each have a specific geometry, which …read more

The Thing is an unassuming name for an ambitious project to build an FPGA board from easy to find components.
The project stems from an earlier build submitted to the 2018 Hackaday Prize by [Just4Fun] where two dev boards – an STM32-based Arduino and an Altera MAX II CPLD board …read more
When life gives you lemons, you make lemonade. At least that’s what the [Sprice Machines] thought when they decided to turn a house into the set of a 9-minute long Rube Goldberg machine to make lemonade. (Video embedded below.) The complex chain reactions runs across multiple rooms, using everyday objects …read more

Jibo, the adorable robot made by Jibo, Inc., was getting phased out, but that didn’t stop [Guilherme Martins] from using his robot companion for one last hack.
When he found out that the company would be terminating production of new Jibos and shutting down their servers, he wanted to replace …read more

Some 3D printers will give you prints with surfaces resembling salmon skin – not exactly the result you want when you’re looking for a high-quality print job. On bad print jobs, you can usually notice that the surface is shaking – even on the millimeter scale, this is enough to …read more
Light painting has long graced the portfolios of long-exposure photographers, but high resolution isn’t usually possible when you’re light painting with human subjects.
This weekend project from [Timmo] uses an ESP8266-based microcontroller and an addressable WS2812-based LED strip to paint words or custom images in thin air. It’s actually based …read more
