Not too long ago, part of using a computer was often finding the correct disk for the application you wanted to run and inserting it into your machine before you could start. With modern storage, this is largely a thing of the past. However, longing for some of that nostalgia, [ItsDanik] has been developing the […]
The Proxmark3 PCB 125kHz antenna., GNU GPL version 2, GitHub link. Picture this: It’s the end of the year, and a few hardy souls gather in a hackerspace to enjoy a bit of seasonal food and hang out. Conversation turns to the Flipper Zero, and aspects of its design, and one of the parts we […]
Ever hear of the Phoniebox project? If not – tune in, that’s a hacker’s project your entire family will appreciate. Phoniebox is a software suite and tutorial for building a jukebox controlled through RFID cards, and it can play audio from a wide variety of sources – music and playlists stored locally, online streams like […]
Like many creative individuals who suddenly find themselves parents, [Marta] wanted to make something special for his children to play with. Anybody can just purchase an off-the-shelf electronic toy, but if you’ve got the ability to design one on your own terms, why not do it? But even compared to the fairly high standards set […]
Some people get inked, while others get henna or those water transfer tattoos you might find in a box of Cracker Jack. [Becky] wanted the benefits of having an RFID tag in her finger — unlock doors or log into your computer with a swipe of your finger — but wasn’t ready to get an […]
I’m often asked to design customer and employee tracking systems. There are quite a few ways to do it, and it’s an interesting intersection of engineering and ethics – what information is reasonable to collect in different contexts, anonymizing and securely storing it, and at a fundamental level whether the entire system should exist at […]
In the movies, the most-high tech stuff is always built into a briefcase. It doesn’t whether whether it’s some spy gear or the command and control system for a orbiting weapons platform; when an ordinary-looking briefcase is opened up and there’s an LCD display in the top half, you know things are about to get […]
Cyclic redundancy codes (CRC) are a type of checksum commonly used to detect errors in data transmission. For instance, every Ethernet packet that brought you the web page you’re reading now carried with it a frame check sequence that was calculated using a CRC algorithm. Any corrupted packets that failed the check were discarded, and […]
The works of Shakespeare, Goethe, and Cervantes combined do not equal the genius of Rick And Morty. Actually, the word ‘genius’ is thrown around a bit too much these days. Rick and Morty has surpassed genius. This cartoon is sublime. It is beyond any art that could be created. Now, you might not have a high enough IQ […]
NFC locks are reaching a tipping point where the technology is so inexpensive that it makes sense to use it in projects where it would have been impractical months ago. Not that practicality has any place among these pages. IKEA carries a cabinet lock for $20USD and does not need any programming but who has […]
