[sdiy] DIY slide-bars

[Fernando de Izuzquiza]

Hello again,

This is another example (just the first search result for "sharp IR") :

http://www.acroname.com/robotics/parts/R48-IR12.html

This people is asking $11.50 for the Sharp IR modulated sensor pack.  
Infusion is asking $43! Just take a close look at the picture on their  
page and you'll see it's the same Sharp sensor.
I ordered two SlideLong from them since they have a "special" price on  
it ($32 instead of $61) but they asked for $76 as shipping costs!  
F***ing hell! I sent them a message asking for some explanation and  
more shipping options since this is way too much for two flat sensors!  
Oh, this was the cheapest shipping option! Be aware.

We should find direct sources for sensors. Robot parts retailers is  
one, but is possible to go even more direct I believe.

Fernando
