New: BlimpDuino board version 5

BlimpDuino is in the hands of beta testers, so we're doing some last minute tweaks. The current code works on boards version 431 and up (don't ask about the numbering schemes--they're based on internal versions. When we release the commercial board, it will be called V1.0 as usual) . The newest internal version of the board is now V5.1. If you want to order and assemble your own boards before the commerical release, you're welcome to! Order the boards here. ($10 + $10 handling) The Eagle files (PCB and schematics) are here. Once you've built it, instructions for loading the firmware are here. Here are the SMD parts, with their PCB labels, values and Digikey part numbers (see below for direct links and prices)

Remember to watch the polarity of the LEDs ("+"s are marked on the board) and capacitors C1 and C4, which are also marked on the board. Here are the components you'll need (Digikey part numbers unless otherwise stated--prices given were correct at the time of this writing and represent total costs in the case of multiple units):

Capacitors:
1x 100uF 16v 399-5214-1-ND ($0.80)
1x 100uF 6.3v 478-1677-1-ND ($1.25)
7x 0.1uF PCC1828CT-ND ($6.93)
Diodes:
4x Navi LED (green) 67-1357-1-ND ($0.64)
1x Power LED (red) 67-1359-1-ND ($0.18)
or optional (blue) LED 160-1643-1-ND ($0.18)
IC's:
1x Atmega168, ATMEGA168V-10AU-ND ($4.00)
1x TL750L05CLP voltage regulator: 296-8002-5-ND ($0.68)
1x L293D(motor controller)296-9518-5-ND ($1.93)
4x IR sensors (Pololu ($10.00)
1x Maxbotic ultrasonic sensor EZ2 or EZ3 ($27.95)
Resistors:
3x 10kOhms P10.0KCCT-ND ($2.73)
5x 1Kohms P1.00KCCT-ND ($4.55)
Switches,etc (Sparkfun):
Reset button ($0.35)
Switch ($1.50)
1 strip of male pin headers ($2.50)
1x polarized LiPo battery connector: Deans micro plug ($1.49)
1 strip of female machine pin headers (to plug the motors and removable ultrasonic sensor into) ($3.95)
1 strip of male machine pin headers (for ultrasonic sensor and motor leads) ($2.95)

Total, including PCB: $94.56 (not accounting for any volume discounts you may achieve with multiple units)

I should also mention that for the new board (v6) there is a new SMD voltage regulator that isn't on the parts list, and you need a different reset switch, the SMD version from SparkFun:

One correction for the new board (v6): It looks like D1 is the power LED (red or blue) and D2, D3, D4, and D5 are the green Navi LEDs.
