Oreo Construction: Hiding Your Components Inside The PCB

In recent months, the ability to hide components inside a circuit board has become an item of interest. We could trace this to the burgeoning badgelife movement, where engineers create beautiful works of electronic art. We can also attribute this interest to Bloomberg’s Big Hack, where Jordan Robertson and Michael Riley asserted Apple was the target of Chinese spying using components embedded inside a motherboard. The Big Hack story had legs, but so far no evidence of this hack’s existence has come to light, and the companies and governments involved have all issued denials that anything like this exists. …read more

Hackaday Superconference: Estefannie’s Daft Punk Helmet

There’s no single formula for success, but if we’ve learned anything over the years of covering cons, contests, and hackathons, it’s that, just like in geology, pressure can create diamonds. Give yourself an impossible deadline with high stakes, and chances are good that something interesting will result. That’s what Estefannie from the YouTube channel “Estefannie Explains It All” did when Bay Area Maker Faire was rolling around last year, and she stopped by the 2018 Hackaday Superconference to talk about the interactive Daft Punk helmet that came out of it.

It’s a rapid-fire tour of Estefannie’s remarkably polished replica of …read more

The Art of Vacuum Tube Fabrication

Vacuum tubes fueled a technological revolution. They made the amplification of signals a reality for transatlantic telephone cables (and transcontinental ones too), they performed logic for early computers, and they delivered that warm fuzzy sound for high fidelity audio. But they were labor intensive to produce, and fragile, so semiconductors came along and replaced tubes in almost every application. But of course tubes are still with us and some tube applications are still critical — you’ll find them used in high-power RF and there are even satellites that depend on klystrons. So there are still experts in tube fabrication around, …read more

Homemade Shop Vise Packs a Hydraulic Punch

It’s a sad day when one of the simplest and generally most reliable tools in the shop – the bench vise – gives up the ghost. With just a pair of beefy castings and a heavy Acme screw, there’s very little to go wrong with a vise, but when it happens, why not take it as an opportunity to make your own? And, why not eschew the screw and go hydraulic instead?

That’s the path [Darek] plotted when his somewhat abused vise reached end-of-life with an apparently catastrophic casting failure. His replacement is completely fabricated from steel bar and channel …read more

Scooter Hauls Kids With A Little Heavy Metal

Where there’s a will, there’s a way. Similarly, where there’s a paying customer and a well stocked metalworking shop, there will also be a way. That’s about all the backstory you need to understand this latest creation from [Richard Day] of 42Fab. A customer asked him to build something that didn’t exist, and in a few hours he not only fabricated it from scratch but documented the whole thing for our viewing pleasure.

The object in question is a mount that would allow the customer to pull a “Burley Bee” kid trailer behind their electric scooter. The trailer is only …read more

A CNC Woodworking Tool That Does The Hard Parts

Drawn along in the wake of the 3d printing/home shop revolution has been the accessibility of traditional subtractive CNC equipment, especially routers and mills. Speaking of, want a desktop mill? Try a Bantam Tools (née Othermachine) Desktop Milling Machine or a Carvey or a Carbide 3D Nomad. Tiny but many-axis general purpose mill? Maybe a Pocket NC. Router for the shop? Perhaps a Shapeoko, or an X-Carve, or a ShopBot, or a… you get the picture. The MatchSticks device is a CNC tool for the shop and it might be classified as a milling machine, but it doesn’t quite work …read more
