Mathieu Stephan is an open source hardware developer, a Tindie seller who always has inventory, a former Hackaday writer, and an awesome all-around guy. One of his biggest projects for the last few years has been the Mooltipass, an offline password keeper built around smart cards and a USB interface. It’s the solution to Post-It notes stuck to your monitor and using the same password for all your accounts around the Internet.
The Mooltipass is an extremely successful product, and last year Mathieu launched the Mooltipass Mini. No, it doesn’t have the sweet illuminated touch-sensitive buttons, but it is a …read more
Printed circuit boards are a fundamental part of both of commercial electronic equipment and of the projects we feature here on Hackaday. Many of us have made our own, whether done so from first principles with a tank of etchant, or sent off as a set of Gerbers to a PCB fab house.
To say that the subject of today’s Retrotechtacular is the manufacture of printed circuit boards might seem odd, because there is nothing archaic about a PCB, they’re very much still with us. But the film below the break is a fascinating look at the process from two …read more
Next week we’ll be at a few awesome hardware meetups around the Bay Area, and we want you to head out and join us.
The first meetup will be the Silicon Valley Hardware Meetup at the Evil Mad Scientist shop in Sunnyvale. It’s going down Wednesday, December 6th, from 6:30 until 9:30. At least some of the Hackaday/Tindie/Supplyframe crew will be there, and the night will be filled with lightning talks, demos, and the cool hardware people you know and love.
Speakers for this meetup will include [Mitch Altman], hacker extraordinaire and owner of far, far too many TV remotes. …read more
If you know anyone who is serious about baking, there’s a good chance you’ve seen one of these classic KitchenAid mixers. Built to last, they are often handed down generation to generation (or at least, when a newer model comes out), which is how [Kaitlin Flannery] received hers. While it didn’t look too bad considering its long life and the fact it’s been through a motor replacement already, she decided to spruce it up a bit by stripping it down and repainting the whole machine.
These KitchenAid mixers are solidly built and look highly serviceable, it’s refreshing to see a …read more
If you’re comfortable with the technical side of becoming a consultant or contractor but are unsure what to charge for your services, you’re not alone. “How much do I charge?” is a tough question, made even tougher by the fact that discussing money can be awkward, and at times virtually taboo.
As a result it’s not uncommon for the issue to get put off because it’s outside one’s comfort zone. Technical people in particular tend to suffer from an “if you build it, they will come” mentality; we get the technical side of things all figured out and just sort …read more
For this week’s Hack Chat, we’re talking about reverse engineering the Digital Compact Cassette. Why should we care about an obsolete format that was only on the market for four years? Because if a copy of the Spin Doctor’s Pocket Full of Kryptonite costs $50 USD on the used market, it has to be good.
In the early 1990s, several different digital magnetic tape formats came onto the scene. The MiniDisc was magneto-optical, yes, but back in the day it was amazing for recording bootlegs. DAT also appeared in the early 90s, and it was a godsend for recording studios. …read more
Mike Ossmann and Dominic Spill have been at the forefront of the recent wave of software-defined radio (SDR) hacking. Mike is the hardware guy, and his radio designs helped bring Bluetooth and ISM-band to the masses. Dominic is the software guy who makes sure that all this gear is actually usable. The HackRF SDR is still one of the best cheap choices if you need an SDR that can transmit and receive.
So what are these two doing on stage giving a talk about IR communication? Can you really turn traffic lights green by blinking lights? And can you spoof …read more
What were you doing in 2004? Can you even remember 2004? Maybe it’s like the old joke about the 1960s, if you can remember it, you weren’t really there, man. Cast your mind back, [Lance Armstrong] was winning the Tour de France, and SpaceShipOne made it into space.
[Gregg Eshelman], wrote to us to say that in 2004 he bought an MP3 player. Ask your parents about them, they were what hipsters used before they had cassette tapes: portable music players that everyone thought were really cool back then, onto which music didn’t come from the Internet but had …read more
Today, we’re calling all hackers to do the most with a single coin cell. It’s the Coin Cell Challenge, and we’re looking for everything from the most low-power electronics to a supernova in a button cell battery.
Electronics are sucking down fewer and fewer amps every year. Low power is the future, and we’re wondering how far we can push the capabilities of those tiny discs full of power. The Coin Cell Challenge is your chance to plumb the depths of what can be done with the humble coin cell.
This is a contest, and as with the tradition of …read more
Recently, a YouTube video has been making the rounds online which shows a rather astounding comparison between two printed models of the US Capitol. Starting with the line “3-D PRINTERS CAN NOW PRINT TWICE AS FAST”, the video shows that one print took four hours to complete, and the other finished in just two hours by virtue of vibration reducing algorithms developed at the University of Michigan. The excitement around this video is understandable; one of the biggest limitations of current 3D printer technology is how long it takes to produce a model of acceptable quality, and if improvements to …read more
