The new V2.0 kit remains very similar to the older V1.5 and V1.6, with the exception of using a new compass module. We were forced into this change because the old HM55B is no longer made by Parallax. After much searching, we found the LSM303 module by Pololu. This module includes a 3-axis accelerometer and 3-axis magnetometer, which allows the device to preform tilt compensation. It should yield slightly superior performance in situations where the North Paw is inclined, e.g. when driving. In practice, the experience of wearing North Paw is not noticeably different. The cost to produce the kits has increased slightly (because the quantity discounts for this module are not as good as for the HM55B), but we decided to just eat the difference in cost, so there has been no change in the price of the kit. Kit contents:

  • Electronics (anti-static) bag
  • 2 pieces of sticky-back velcro
  • 8 sticky-back velcro dots
  • 12″ of 10 conductor ribbon cable
  • 8″ piece of 1/16″ shrink tubing
  • Small black plastic enclosure box
  • LiPo Battery
  • 10″ custom armature fabric (veltex, velcro and zipper) enclosure
  • LSM303 compass module in pink bag

Electronics bag contents:

  • Custom North Paw V2.0 PCB
  • 2 10kOhm resistors
  • 1 green LED
  • 2 0.1uF caps (little yellow ones, some have very long leads)
  • 1 large 47uF electrolytic cap
  • ATMEGA168 28DIP IC
  • TPIC 16DIP IC
  • 1×3 and 2×3 right angle female header sockets for compass (these may be still included, but are no longer required)
  • 3 pin resonator (blue)
  • switch STDP
  • 2×5 male right angle motor socket
  • LSM303 compass module with Headers, in pink bag
  • ribbon cable snap (times 2, only 1 required, this gives you an extra shot at the nerve-wracking process of putting the snap on the ribbon cable)
  • 8 coin-type vibrating motors (not shown)
  • 330 Ohm resistor
  • red LED
  • JST power jack for battery
  • MAX1555 – SMD device already soldered to the PCB, IC for charging LiPo batteries
  • 1uF cap – larger yellow capacitor (some have very short leads)
  • USB mini-B jack (note: USB-mini cable, required for charging, not included)

 

 


V1.5 Kits

The older V1.5 North Paw kit uses a Lithium Polymer battery and includes on-board charging circuitry, making it very convenient to use – simply plug in a mini-USB cable (not included) each evening and it’ll be fully charged again the next day. The included LiPo battery is considerably smaller and lighter than the equivalent AAA batteries, which previous versions of the kit used. The V1.5 kit used to cost $149.

V1.5 Kit - Front

The V1.5 kits are a considerable improvement over the older V1.0 kits. In addition to the support for superior LiPo batteries, the new kit includes much smaller laser cut acrylic enclosure for the electronics, a better anklet (now with velvet!), and some substantial improvements that make the hard part of the assembly easier than before.
