Mystery Object Time again

Yes its that time again...........Mystery object to be identified

What is it and how will it be used ?  (wild guesses also encouraged).

Only clue is that its for my latest Picaxe project (would you believe), and promises to be a cool addition ..... when its programmed..

Ok..... i could not wait to post some Video of Basic System

Part 1  (None Stream Link1) Video shows basic example of it working - The working version will have the Wiimote mounted on the ceiling looking down onto the floor.

Part 2 (None Stream Link2) Video shows what i eventually intend to do with the information gathered (Robotic ArtWork ala Picaxe (codename Picaxxo(Picasso)))

The RX unit has the other side of the QRD's hooked up?

The shape of the triagular form is very important - if it where an equal sided triangle then it would be worthless....

0.000003 megapixel camera? (did I get the right number of zeros in there?)
Really tiny hurricane tracker? (as in tracker of tiny hurricanes, not tiny tracker of hurricanes)
Snail slime trail mapper?


A device to track the migratory patterns of three (very inebriated) European swallows?
Anything that ban be described using the phrase "soft-baked buns of awesome!"?

Very good "kuck-ku" guess and not a million miles from the intended use .( 1 too many zeros though)

You are the closest yet - the formation of the three swallows are fixed BTW

or an emittor.
Link for the data sheet, if you dare.....

Here is a reliable datasheet

However your maths expertise is more fitting for this mystery.

Looks like 3 QRD1113s or QRD1114s, which are reflective object sensors. I'd say you are going to use them for line following or edge detection, since their range is only 0.5cm.

That's not a very creative idea, and you always seem to come up with very creative ideas. If the color display in the background a hint, then it sounds like you've found a more creative use for them.

With these connected to an ADC input, I think you can still only tell the difference between dark and light (or black and white). Have you found a way to work with color detection?

QRD1114s are thier flavour - but 1113s would work too..

i am running the qrds at 30ma only and the application has a detect range of say 5 meters (yes 5 meters - maybe more with 50ma)

No its not a line following gadget .........or a colour detector

The coloured background is a big ....but "cluttered"  clue........

Hehe......yes they are QRDs (that helps a lot) 

......the mystery continues........
