Minecraft and Forge: Try This Amazing Way to Visualize Logic

I’ve got virtual circuits on the mind lately. There are a myriad of tools out there that I could pick up to satisfy this compulsion. But the one I’m reaching for is Minecraft. I know what you’re thinking… a lot of people think Minecraft is getting long in the tooth. But chances are you never tried some of the really incredible things Minecraft can do when it comes to understanding logic structures. This goes way beyond simple circuits and easily hops back and forth over the divide between hardware logic and software logic.

Traditional Circuit Simulation

Circuit simulation is a …read more

Precision Pantograph Probes PCBs

Electronic components are getting smaller and for most of us, our eyesight is getting worse. When [Kurt] started using a microscope to get a better view of his work, he realized he needed another tool to give his hands the same kind of precision. That tool didn’t exist so he built it.

The PantoProbe is a pantograph mechanism meant to guide a probe for reaching the tiny pads of his SMT components. He reports that he has no longer has any trouble differentiating pins 0.5 mm apart which is the diameter of the graphite sticks in our favorite mechanical pencils. …read more

The Hackaday Prize: Exoskeletons for the Masses

While medical facilities continue to improve worldwide, access to expensive treatments still eludes a vast amount of people. Especially when it comes to prosthetics, a lot of people won’t be able to afford something so personalized even though the need for assistive devices is extremely high. With that in mind, [Guillermo Herrera-Arcos] started working on ALICE, a robotic exoskeleton that is low-cost, easy to build, and as an added bonus, 100% Open Source.

ALICE’s creators envision that the exoskeleton will have applications in rehabilitation, human augmentation, and even gaming. Also, since it’s Open Source, it could also be used as …read more

Ask Hackaday: What Should Father Christmas Bring From Shenzhen?

Imagine this, you have a friend who grew up in Shenzhen, China. The place from whence all your really cool electronics come these days. They speak Chinese in a way only someone born there can, and given that you know them through a shared interest in hardware hacking you can assume they know their way round those famous electronics marts of their home town.

Now, imagine that in a rash move, your friend has offered to pick up a few bits for you on their next trip home. A whole city-sized electronic candy store opens up in front of you, …read more

Electronica 2016: Too Much Electronics

The Electronica trade show in Munich is so big that it only takes place once every two years. Every manufacturer, distributor, and maker of anything electronic is there. To get a feel for the scale of things, Electronica is spread out over twelve large exhibition halls and is served by two separate subway stations, one on either end. You wouldn’t think there would be so many inductor manufacturers in the world, but you’d be wrong.

It’s a hardware geek’s paradise, even if it is aimed more at facilitating industry contacts than at serving the humble hacker. But it’s great to …read more

A Short Introduction to Staking and Potting

Staking and potting are not often used in the hobby electronics world, not really entering to the common vernacular. However, everyone who’s ever busted out a glue-gun to convince that dang wire that keeps coming loose to stay has done it.

However, as [Sean Thomas] touches on, staking is not necessarily as easy as a dob of hot glue. There is a method to the madness. [Sean] gives some examples in pictures, but also directs people to the excellent NASA standard methods for staking. It’s surprising how many unintuitive caveats there are to the proper technique.

Potting, or covering everything …read more
