The may very well be the smallest homemade TTL CPU we’ve ever seen. Measuring at one square inch, this tiny chip boasts 40 connections, an 8-bit databus, a 16-bit address bus, a 64 kB memory space, reset and clock inputs, and 5 V power lines.
TTL (transistor transistor logic) logic …read more

When it comes to architectural features, there are probably not many as quintessentially memorable as arches. From the simplicity of the curved structure to the seemingly impossible task of a supposedly collapsable shape supporting so much weight in mid-air, they’ve naturally fascinated architects for generations.
For civil engineers, learning to …read more
What’s more awesome than a normal hexapod robot? What about a MEGA hexapod?
Max the Megapod, a six-legged 3D-printed walking robot, is an open source, Arduino-based, Bluetooth controlled, Scratch programmable creation made possible by [Steven Pendergrast]. The design for Max was based on a previous hexapod project, Vorpal the Hexapod, …read more
This servo/gear reduction was assembled with almost all 3D-printed parts. Apart from a brushed 36 V DC-motor, a stainless steel shaft, and screws for holding the servo together, the only other non-printed part is the BTS7960B motor driver.
Some interesting stats about the plastic servo – its stall torque is …read more
There’s been a lot of Altoids tin hacks over the years, but a vacuum cleaner in a tin is something new. In [Toby Bateson]’s first project on Hackaday, he used simple household items to create a functioning vacuum cleaner to use for sucking crumbs out of your keyboard or paper …read more

Blindsided by missing pin allocations? Perhaps you’re working on a piece of hardware and you notice that the documentation is entirely wrong. How can you get your device to work?
[Dani Eichhorn]’s troubles began when running an IoT workshop using a camera module. Prior to the work, no one had …read more
Of all the tools that exist, there aren’t many more futuristic than the plasma cutter, if a modern Star Wars cosplay if your idea of futuristic. That being said, plasma cutters are a powerful tool capable of making neat cuts through practically any material, and there are certainly worst ways …read more
One of the biggest dreams anyone has is to make a living doing what they love. For all hackers, makers, and DIYers with a passion for embedded systems, it may make sense initially to pursue embedded systems design as a possible career, but without so much information on the types …read more
Just two weeks ago, the crew from the International Space Station released a photo of their nine crew members – an odd number considering that the facility only has space to house six astronauts at a time. In fact, the crew had just gathered for a celebratory dinner before three …read more
If you thought your handheld digital oscilloscope was the most transportable of your signal analyzing tools, then you’re in for a surprise. This oscilloscope made by [Mark Omo] measures only one square inch, with the majority of the space taken up by the OLED screen.
It folds out into an …read more
