Since we're on the topic of sensors, does anybody have some references for cheaper sensors than the commercial ones provided by Teabox and I-Cube. EUR 90 (and up and up and up) seems pretty steep for what they actually are. I'd be interested in European sources for accellerometers, pressure, bend and other "fancy" sensors if people have these resources handy.
yes, me. ;-)
tell me what you want, and i will tell you what it will cost. best would be if there are more than one person interrested in a given type of sensor, because ordering the parts is what costs also. imagine, 18$ shipping for a 2$ chip .....
pressure sensors (for air pressure) are about 20 $, they can directly connect to such a interface. (see freescale.com, they also offer samples)
acceleration/tilt sensor, three axes, is about 10 $, with some extra circuitry to interface it will add to 15-20$ (again freescale, and again samples are available)
bend sensors are also about 10 $, they just require an extra resistor (about 8 cent) to be used same for force sensors (where you apply pressure with a finger or such) are about 10-15$, depending on size.
piezo sensors are between 2,50 $ and 7,50 $, again some circuitry is needed, so it will be around 10-15$
light sensor is an inexpensive ldr (photoresistor) + resistor, 2$
(see http://www.imagesco.com/catalog/sensors/index.html for the last three)
oh, not to mention that simple pot's and faders are as low as 50 cent, if you grab them from a surplus, high quality stuff is around 5 dollars each ....
add to all that some wire and plugs as you need, and youre done.
again, tell what you want exactly, im sure we can work something out....
best, d.
greetings,
chris
