Fresh hacks every day
This project shows you one possible way to use HTML5 to fully integrate sensor data from a microcontroller into our technological lives. Now, when we saw this tip come through our inbox we thought it would be an interesting example to learn from but we weren't ready for how truly cool the setup is. Take a look at the video after the break and you'll see that scanning the QR code on the project box … [Read more...]
Love them or hate them, plenty of people around the world use QR codes on a daily basis. Since he thinks they’re pretty great, Hackaday reader [falldeaf] thought it would be cool to put together an automatic QR code generator to be used on web sites. Inspired by the custom QR logo embedding work done by our own [Brian Benchoff], his dynamic QR code generator allows you to do the same thing, … [Read more...]
While [Oryx] is down with social media like Facebook and Twitter, there are times when he wants to share things with people he is hanging out with in the real world.

After seeing this video he realized that a tattoo could have dynamic content through domain redirection. [Lifespan] spent a lot of time going over the different styles of 2D bar codes. QR codes were deemed ugly because of the three large squares in the corners. An EZ … [Read more...]
After writing this post on somone hacking QR codes, Hack A Day commenters came out in full force posting some really cool links about modifying QR codes to include a logo. I'll fully admit I geeked out a little, but in the process I figured out some of the theory behind embedding logos in QR codes. After getting my hands on the ISO 18004 specification for QR codes, I decided to try embedding … [Read more...]
QR codes are everywhere these days, from being printed onto receipts to chiseled into granite tombstones. [Will] came up with a way to modify existing QR codes, and his hack has the potential to cause quite a bit of harmless mischief. [Will]'s hack involves a little photo editing, transparency film, and some white-out/Liquid Paper/Tippex. After the 'target' and 'destination' QR codes have … [Read more...]
