Too much to write about.

I could write a ton of stuff for one huge update, or I could write one thing in detail, and have something to post about in a few days, so what do you think imma do?

Robotics has always been a fascination of mine.  I've never tinkered much with electronics or mechanics up until this year.  I own an arduino microcontroller, and soon will own a Teensyusb board.  The teensyusb is cheaper, has more ram, flash ram, and i/o's than the arduino, and has a USB connection, verses the serial, or usb port that acts as serial on the arduino.  In addition, it's MUCH smaller.  I'll be using the Teensyusb controller for some projects of mine, including...


One of the things I've built recently are gloves that deliver an electric shock to any conductive object that is struck with them.  It was a simple circuit for the prototype - I hacked some PCI slot covers from a desktop computer into metal contacts, mounted them on rubber stands, and glued the stands to a glove, on the index and middle finger.  I then wired a lead from one of them to the end of some capacitors, and the other lead to a DPDT switch, which then connected to the caps again.  Another mode on the switch connected the capacitors to a diode bridge, which in turn was wired to a standard two prong power cable, to charge straight from any 120v wall outlet.

I'm going to be doing a LOT more with the next version of the gloves, including higher amperage storage, multiple capacitor banks for multiple shocks, and a gauge  to show power across the cap banks.  Additionally, the prototype looked really ghetto, so I'll be working on making them look less like a mishap and more like a coherently well designed death contraption.

More updates to follow!
