Knobbed cylinder variation. A straw is placed into a hole and the child finds the cylinder to go in the hole.
The touch-sensors are made by inserting a tight copper coil into the button hole and then adding a acrylic plug with LED.
NOTE: This is just a temporary solution, not the final install

Image processing, motion sensing, bio sensing, wireless network technology, and human interface sensors were shown.
A 100-watt CO2 laser is shown here (the section glowing in blue) melting and transforming a rod of alumina into a pure sapphire optical fiber. A pair of telocentric lenses with machine vision cameras control the movement rate of the feedstock and fiber, and after many hours of automatic machine-operation, a long continuous piece of sapphire optical fiber can be formed. Such a fiber is one of the more durable materials on the planet, able to withstand temperatures as high as 1,800 degrees Celsius. The glowing pink section is a helium-neon laser which is a component of the laser Heated Pedestal Growth System. It is a visible red laser that is aligned to co-propagate along with an invisible 10.6um CO2 laser beam. The red laser then helps operators to locate and align the invisible laser beam.
Testing the EE-SY313 reflective opto-sensor. The LED lights up, but goes out when an infra-red reflective surface is detected. We'll be using black marker pen marks on white paper. Photo by David Henshall.
i finally got up the courage to clean my sensor. i think it worked out pretty well. top left is "before", top right is after the first cleaning and the bottom image is after i cleaned it again.
i used a swab made by microtools. they are not as lint free as they say and the size was a little off (which was annoying b/c the exact size thing was the whole reason i didn't just make my own swab), but it worked very well.
cleaning your own sensor is pretty easy, but if you damage the sensor, it can cost almost as much as a new camera to repair it, so beware.

Here is a shot of the external dual sensor box. The sensors are set up to line up nearly at the edges of a 35mm SLR film window.
A small switch on the back selects which pair is used for making measurements. In this way curtain shutters that move vertically or horizontally can be measured.
After looking at the sensor for a professional shutter tester, I may make those round holes slits instead.
This complicates the light source, in that it needs to be much more direct, and not just diffused light.
..AKA lie detector - MrC has been fibbing ;-)
I have been plotting a GSR dress since spring and bought this kit way back then to mess about with a simple circuit to see how well it worked. I've been so busy I've only just got around to soldering this GSR kit together, however it's not sensitive enough for the dress I'm making.
After a replacement Heath/Zenith 5411-A motion sensor failed the same way (bad design) the first one did in a porch light (would only turn on in test mode), I decided to use a Regent motion sensor instead. This involved making an adapter between the Regent box and the Heath ball-and-socket swivel, which fits in a standard hole in an exterior electrical box (good design).
I needed to use the putty knife to get past all the plastic snap-tabs on the Regent unit (bad design).

Check if your sensor needs cleaning: Set your camera to Aperture priority, at f/22, and take a shot of a cloudless blue sky (focus not important)... If you see specs, you need to clean your sensor...
There is a tutorial here: www.copperhillimages.com/index.php?pr=tutorials
(Yes, there is still a spec on the after pic.. I got it off, but was using white paper to check then, and I wanted the before/after pic here to be the same color)
