Have you ever found yourself in a crowded restaurant on a Saturday night, holding onto one of those little gadgets that blinks and vibrates when it’s your turn to be seated? Next time, bust out the HackRF and follow along with [Tony Tiger] as he shows how it can be used to easily fire them […]
The regular Hackaday reader might remember the iClicker from our previous coverage of the classroom quiz device, or perhaps you even had some first hand experience with it during your university days. A number of hackers have worked to reverse engineer the devices over the years, and on the whole, it’s a fairly well understood […]
A factory is a machine. It takes a fixed set of inputs – circuit boards, plastic enclosures, optimism – and produces a fixed set of outputs in the form of assembled products. Sometimes it is comprised of real machines (see any recent video of a Tesla assembly line) but more often it’s a mixture of […]
When a tip comes in and the tipster feels they have to reassure us that despite appearances their subject is not facilitating crime, it certainly gets our attention. [Flam2006] has a Brinks home security system which can only be configured using a special device only available to installers, and though they managed to secure one […]
In general, tattoo artists are not electrical engineers. That’s fine; the world needs both professions. But when you need a circuit designed, you’re better off turning to an EE rather than a tattoo artist. And you certainly don’t want an EE doing your new ink. Disaster lies that way. Surprisingly, [Missa]’s tattoo of a heart-shaped […]
Figuring out the maximum number of peripherals which can be sensed or controlled with a minimum number of IOs is a classic optimization trap with a lot of viable solutions. The easiest might be something like an i2c IO expander, which would give you N outputs for 4 wires (SDA, SCL, Power, Ground). IO expanders […]
Perched atop a dormant volcano far above the roiling tropical air of the Big Island of Hawai’i sit two of the largest optical telescopes in the world. Each 10-meter main mirror is but a single part of a magnificent machine weighing in at some 400 tons that needs to be positioned with incredible precision. Keeping […]
[Mike Harrison] produces so much quality content that sometimes excellent material slips through the editorial cracks. This time we noticed that one such lost gem was [Mike]’s reverse engineering of the 6th generation iPod Nano display from 2013, as caught when the also prolific [Greg Davill] used one on a recent board. Despite the march […]
