<p>Parallax tends to make a lot of effort to document and nicely package its sensors. Adafruit as well. However you can often buy functionally very very similar sensors more cheaply from bulk electronics suppliers or ebay.</p>

<p style="font-size:12px"><font face="Verdana">OK, here I am again with another "dumb" question… well, maybe not so dumb after all as I'll bet there are others out there who could also use this information. On the OLPC wiki there are several very nicely illustrated instructions about how to make sensors to use with the XO… temperature, humidity, light, etc. But, they don't include a materials list or reference to sources where the parts can be purchased.</font></p>

<p style="font-size:12px"><font face="Verdana">Radio Shack? Edmond Scientific? Parallax.com? or where? Curious people, myself included want to know. Can someone help here?</font></p>

<p style="font-size:12px"><font face="Verdana">P.S. Here's an example of the type of info needed. This site sells a number of light sensors but they call them things like Photoresistor, Photo Transistor, Light to Frequency Converter. These are all little ones that appear similar to the one in the instructions on the wiki. How do you tell which kind you need?</font></p>
