Blaise Pascal is known for a number of things, but we remember him best for the Pascaline, an early mechanical calculator. [Chris Staecker] got a chance to take a close …read more| Hackaday
In a recent write-up, [David Delony] explains how he built a Wolfram Mathematica-like engine with Python. Core to the system is SymPy for symbolic math support. [David] said being able …read more| Hackaday
It is hard to remember a time when no one had a spreadsheet. Sure, you had big paper ledgers if you were an accountant. But most people just scribbled their math on note paper or, maybe, an enginee…| Hackaday
Our Hackaday colleague [Bil Herd] is known for being the mind behind the Commodore 128, a machine which famously had both a 6502 and a Z80 processor on board. The idea of a machine which could do t…| Hackaday
Compared to the old 8-bit Arduinos, it’s incredible how cheap modern microcontrollers like the ESP32 have become. But there are even cheaper options out there if you don’t need that kin…| Hackaday
The cool thing about building your own computer is that you don’t have to adhere to industry norms of form and function. You can build whatever chunky, awesome thing your heart desires, and t…| Hackaday

The chiptune music scene is largely rooted in the sounds of the original Nintendo Game Boy and the Commodore 64, while still welcoming a wide range of other hardware under its general umbrella. Sti…| Hackaday
It is easy to write off Tinkercad as a kid’s toy. It is easy enough for kids to learn and it uses bright colors looking more like a video game than a CAD tool. We use a variety of CAD tools, …| Hackaday
The original Stream Deck was a purpose-built device to make it easier to manage a live video stream on the fly. Since its release, many other similar products have hit the market. Among them is the…| Hackaday
Over on YouTube, [The Modern Rogue] created an interesting video showing a slide-rule-like encryption device called the Réglette. This was a hardware implementation of a Vigenère-like Cipher, technically referred to as a manual polyalphabetic substitution cipher. The device requires no batteries, is fully waterproof, daylight readable and easy to pack, making it really useful if you find yourself in a muddy trench in the middle of winter during a world war. Obviously, because it’s a slide...| Hackaday

Most of us have, or, would like to have a 3D printer, a laser engraver, and a CNC machine. However, if you think about it naively, these machines are not too different. You need some way to move in…| Hackaday
Modern multi-material printers certainly have their advantages, but all that purging has a way to add up to oodles of waste. Tool-changing printers offer a way to do multi-material prints without t…| Hackaday
