5 - Che dite me lo prendo? :)

e prova a pensare di triggerare qualche sensore tipo lamp alle varie entrate della scheda audio

1_Io voglio realizzare un guanto e ci siamo orienteti su Teabox :

          1_Dual-Axis Accelerometer and Tilt Sensor
          1_Gyroscope
          3_Bend/Flex Sensor

Sono curioso di sapere il parere del tuo amico. Speriamo bene.

I want to build a Glove and using sensors an Teabox .
My project is:
1_Teabox
1_Dual-Axis Accelerometer and Tilt Sensor
1_Gyroscope
3_Bend/Flex Sensor
My biggest concern is how you want to connect the Glove sensors to the teabox. You have 6 sensor outputs listed above. You could bundle those together on 2 6 conductor RJ-11 telephone cables which would run right into the teabox. That would be the easiest way to do it. If you wanted it on one cable you would then need to split it back up at the Teabox before running it into the inputs.
If you are looking for a pcboard to solder to, if you give me an idea of what you need, I can look through our stacks to see if there is something that would work. In general they would be $5 or less.
I'm actually making something similar for an extended harmonica interface. I'm making some changes to one of our pcboards so that I can have 2 RJ-11 jacks that are easy to solder to, which will be mounted on my wrist and split out to the other sensors. That way there's one point where all the sensors congregate before being sent to the Teabox. How were you thinking of connecting the sensor glove to the teabox?
_Have you done it before?
_Any suggestion?
The trick may be attaching the sensors to a glove that isn't too cumbersome. I've been toying with the idea of ditching the glove and attaching stuff to a wristband and elastic bands around my fingers. I guess we won't know until we try.
_Can i customize from others Analog Devices Sensors ?
Sure. As long as the output is analog, between 0 and 5 volts, you can use any sensor. (0.25 -4.75v is best - this is Analog Devices' standard) You can make your own sensors or buy others. One thing to look out for is that the Teabox will only support 250mA of power. Most sensors use so little that this doesn't matter, but some, like sharp IR sensors use 50mA a piece and can add up quickly. If this becomes a problem, we have a power injector that can add more power to the sensors, but I doubt you'll reach that point.
_The Dual-Axis Accelerometer and Tilt Sensor has got just two
outputs , where do i get the tilt value ?
The accelerometer is the same thing as a tilt sensor. If you tilt the sensor, it detects the forces of gravity and sends out a voltage range of around 2.0 to 3.0. Faster movements will cause it to swing to the outer voltages. This can cause problematic data if you bump the sensor because it will sense the deflection, not just the tilt. You can put a low pass filter on the data to keep any spurious movements out, but it makes it less responsive. As far as I know, there are no tilt sensors that overcome this problem. If you find one let me know, I'd be interested to look at it.
Our Tilt version of the Accelerometer scales the signal so that it the tilt saturates the entire sensor input range.
If you have any other questions or need clarification, please let me know

(magari sentiamoci privatamente che esula un po dall'interesse comune.. :) )

Appena arrivano le macchine per Namaste e me vi facciamo sapere :)
