Hi Tony,

sp03: http://www.acroname.com/robotics/parts/R184-SP03.html and this
Nice little beast!


However after reading through the docs, it appears the nxt only
provides 4.3v, but the sp03 requires 4.5 - 5.5v.  For people who know
better, would this mean I wouldn't be able to power it using the power
from the sensor port directly?  Would that 0.2v make a difference or
could I use the other wire that supplies 9v for rcx-type analog
sensors to power it?

Most probably it should work. I am a bit more concerned about current
consumption (80mA - not 80mAH as shown in documentation!), since the 4.3V supply
can deliver 180mA for ALL seven NXT ports.

You may also use an external supply but you will need to add a 5V voltage
regulator...

I'm a software guy, not a hardware guy. I have very little experience designing circuits. To show how little I know, I'm actually reading through Electronics Projects for Dummies at the moment. ;) Well in this book they describe a simple (...) (17 years ago, 5-Dec-06, to lugnet.robotics.nxt)
