New hardware including 3d Printers are being added!

I  got extremely sidetracked while waiting for a delivery of 10 ultrasonic sensors from China.  It basically took 3 months before the shipper would agree they were lost in transit.  In the mean time,  I received a Christmas gift that took over 100% of my hobby time.  A Printrbot Simple 2013 maker's edition 3D printer.  Since that time I have completely changed the design of that original printer and built 2 more.
  I started designing mod files and even recreating the original Laser-cut DFX files into Printable STL format. If you have a printer you can print your own 2014 Printrbot Simple 1405. If you don't you can commission an owner to print you one or even use a local 3d print service.  Those and all my files can be located at  http://www.thingiverse.com/metaled/designs
  I have a ton of subjects I would like to share hints and tips for.  Don't get me wrong,  I have ordered new Ultrasonic Sensors and do plan to continue sharing that robotics project.  But I  also plan to share Raspberry Pi,  PcDuino,  Arduino,  Intel Edison and lots of electronic circuits with the Lawn Mower Robot assembly!
  I'll try to find time to share as much as possible and if you have any questions,  please feel free to ask in the comment sections!
