Collaborate Disseminate
It’s been a while since we’ve dunked on an autonomous taxi foul-up, mainly because it seemed for a while there that most of the companies field testing driverless ride-sharing services …read more Continue reading Hackaday Links: April 13, 2025
Mechanical switches are pretty easy to understand—the contacts touch, the current flows, and Bob is, presumably, your uncle. But what about soft switches? Well, they’re not that difficult to understand …read more Continue reading Flip Flops Make Great Soft Switches
Really, [OzzieGerff] had us at “LEGO.” But then he took it to another place entirely and built a completely mechanical, nearly 100% LEGO version of Snake. And it’s just as …read more Continue reading A Game of Snake on a LEGO Mechanical Computer
In a lot of ways, Etch-A-Sketch is the perfect toy; simple, easy to use, creative, endlessly engaging, and as a bonus, it’s completely mechanical. We find that last attribute to …read more Continue reading Electronic Etch-A-Sketch, No Microcontroller Required
As hobbies go, stargazing has a pretty low barrier to entry. All you really need is a pair of Mark 1 eyeballs and maybe a little caffeine to help you …read more Continue reading Keeping Track of the Night Sky with Discrete Logic Chips
We’ve all heard of the dangers of static electricity when dealing with electronics, and we all take the proper precautions when working with static-sensitive components — don’t we? But as …read more Continue reading The Other Kind Of Static Hazard to Your Logic Circuits
It looks like [Michal Zalewski] is raising the next generation the right way. First, his eldest son asks for help building a one-bit computer from discrete transistors. Not to be …read more Continue reading Partial Relay-Based Calculator Puts the Click Where it Counts
The digital world offers many advantages over its analog relatives, the use of boolean logic among them. Some of the functions, like NOT, OR, and AND are fairly straightforward and …read more Continue reading Patching Together Logic Gates
We live in a world where most of us take the transistor for granted. Within arm’s length of most people reading this, there are likely over ten billion of them …read more Continue reading GLASNOST is a Computer That Makes Transparency A Priority
As computers get more and more powerful and artificial intelligence algorithms improve, few games remain where the best humans can reliably beat their electronic counterparts. In chess this barrier was …read more Continue reading FPGA Plays Tic-Tac-Toe
