When DIYers combine those cheap, powerful tools with the collaborative potential of the Internet, they can come up with the kinds of innovations that once sprang only from big-budget R&D labs. In 2009, a PhD student named Daniel Reetz turned two Canon PowerShot A590s into an improvised high-speed book scanner. He detailed the project on a website, DIYbookscanner.org, where readers have since posted hundreds of tweaks, suggestions, upgrades, and entirely new designs. The open source MPGuino project, which uses an Arduino microcontroller to track gas consumption as you drive, has inspired a small community of fans who help refine and customize the gizmo.

Obi-Wan Fareed on 02 Nov 11CreateBuzz QR Code creates 2 types of QR Codes. One is normal, and the other is trackable. The trackable QR Code has a different URL. When it is read, it is actually reading the trackable URL which then redirects to the page that was defined initially. Quick tests on several devices and QR Code readers show that some QR Code readers did not do the re-direction. Hence these scans were not tracked. Alternatively, use bit.ly because it tracks clicks. Use the shorten URL to generate the QR Code. Any scan to the QR Code which points to the shorten URL will be recorded. It shows the time the scans were done and region as well.
