Interesting twist on Joule Thief to charge batteries
Nice idea, the author basically tweaked the design with a cap and diode added in to allow a low power charge source, like solar, to charge batteries. http://makezine.com/projects/joule-thief-battery-charger/?utm_source=feedburner&utm_medium=%24%7Bfeed%7D&utm_campaign=Feed%3A+%24%7Bmakezineonline%7D+%28%24%7BMAKE%7D%29&utm_content=%24%7BGoogleReader%7D

Sounds like Texas is tired of Xerox messing up its version of EZPass. And wants $177K. Which is pocket change for the over $100M the contract is for. http://kxan.com/2015/02/02/xerox-fined-by-state-for-continued-txtag-issues/

ZMap, looks like its a faster way to scan a network than nmap
I haven’t had a chance to try this, but the claim to fame for zmap is its really fast at scanning a network vs nmap (which can take 20-40 seconds per IP Address). http://www.darknet.org.uk/2014/10/zmap-fast-open-source-network-scanner/

Converting a paper cutter to laser engraver
This is an interesting build. Actually both bits are, the Silhouette Portrait papercutter is a $200 cheap CNC for paper. Adding the $50 laser for cutting/engraving is a good idea. And could be modified for other existing CNC’s. http://hackaday.com/2015/01/31/paper-cutter-becomes-a-laser-engraver/
