Two-factor authentication is becoming the norm for many applications and services, and security concerns around phone porting hacks are leading to a phaseout of SMS-based systems. Amidst that backdrop, [Josh] developed his own authentication device by the name of Good USB. The device can be built using a Arduino Leonardo, SS Micro, or even a BadUSB […]

The Commodore 64 is a much-loved 8-bit retro computer that first appeared in 1982 and finally faded away around a decade later. The Commodore company started by [Jack Tramiel] went on to make the Amiga, and eventually ceased trading some time in the late 1990s. All history, now kept alive only by enthusiasts, right? Well,
There are a variety of instruments used in sleep studies to measure bodily activity during sleep and consequent sleep quality. Many of them use techniques that perhaps aren’t so easy to replicate on the bench, but an EEG or electroencephalograph to measure brain waves can be achieved using a readily-available module. [Ben Jabituya] shows us a
When it comes to rendering text input into an electronic form,the newest keyboards use USB for wired interfacing, while the oldest Morse keys use a single conductor. Shall the two ever meet? For [Matthew Sparks] the answer is yes, with his “The Gadget” Morse-to-USB HID interface which presents a Morse key to a computer as

The need to provide custom controls for complex software packages has been satisfied in many ways, the most usual of which is to have a configurable keypad. It’s a challenge [Meir Michanie] has taken up in a slightly different way, by creating a custom touch-screen macro pad. Unlike the buttons, this allows entirely custom layouts with
ODD INPUTS AND PECULIAR PERIPHERALS: TOUCH THIS MACRO PAD Continue Reading
The Arduino family of open-source engineering design tools has long been associated with T-shirted hobbyists and garage-based startups. But as part of a realization that many of the platform’s supporters are now in the corporate world, the firm is expanding the availability of its tools for enterprise applications. Arduino’s humble beginnings at the Interaction Design Institute
Stewart platforms are pretty neat, and not seen in the wild all that often, perhaps because there aren’t a vast number of hacker-friendly applications that need quite this many degrees of freedom within such a restricted movement range. Anyway, here’s an interesting implementation from the the curiously named [Circular-Base-Stewart-Platform] YouTube channel (no, we can’t find
We always enjoy videos from [FesZ], so when we saw his latest about tips and tricks for LTSpice, we decided to put the 20 minutes in to watch it. But we noticed in the text that he has an entire series of video tutorials about LTSpice and that this is actually episode 30. So there’s plenty
Those old enough to have encountered punch cards in their lifetime are probably glad to be rid of their extremely low data density and the propensity of tall stacks to tip over. But obsolete as they may be, they’re a great tool to show the basics of binary data storage: the bits are easily visible
