Questions about Teabox & Icube sensors

Hello everyone.
I’m Lambros and this is the first time I’m writing in this forum.I live and work as a freelance musician in Athens. My main interest is interactive projects that are always related to music.
Well..To begin with, I’m trying to find a way to make some Icube sensors work with my Teabox interface. The rest of the stuff is happening in Max. I’ve almost gone through all the kind of internet search for some help and I ended up here thinking that is probably the right place with the right people to talk about it.
In short: I have a couple of Gforce Icube sensors.The values that I’m getting through the Teabox are extremely disapointing. Which make me think, either getting the equivalent electrotap Dual-Axis Accel. or getting a micro-dig from Icube in order to make the Icube sensors working.
Although it still feels a bit wrong to go for another interface (probably slower).

Obviously I have already contacted Electrotap and Infusion, and still waiting for a clue.

Has anyone used the Teabox with Icube sensors?
Had any similar problem?
How could this be solved?

I’d be really happy if anyone could give an insight or show me a place on the net where I could find some help.

Thanx in advance
Lambros

I just typed you a good response but it got deleted, so heres the jist

near the bottom, might help you, im not sure how to translate it into teabox talk.

Infusion systems has been a bit sub-par in terms of customer support, I sent in a couple sensors for repair about a month and a half ago and they still haven’t done anything. I know there a small company but when you pay 120 dollars for a 3 dollar sensor and some wire and all you want is for them to reattach the wires, youd think that you payed all that extra money for tech support.

Tim is great at electrotap, if he had a wireless box Id probably get it.

good luck!

Thanx for the quick reply.

I guess you are talking about the connection diagram near the bottom of the page.
No, it is not a connection issue I’m afraid.
It is about the resolution of the values that I’m getting from the Icube sensor (Gforce).

thanx

Try posting to the electrotap mailing list. AFAIK Tim read this list
only occasionally due to the large traffic here.

Best,
Trond

Keep in mind that the Teabox uses ‘conditioned’ sensors – the Icube
does not. While Icube sensors usually work fine, some may have
impedance and/or stability issues if not properly conditioned. Also,
the pin-out of Icube sensors is opposite that of of Teabox inputs –
the ground & sensor output are reversed (putting the signal ‘out of
phase’). The Teabox inputs are: pin 1 ground, pin 2 sensor, pin 3
power; the Icube sensors are: pin 1 sensor, pin 2 ground, pin 3
power. Depending on the sensor & application, this may not present an
issue, but in some cases it does. For instance, in the Teabox’s
digital inputs using a motion detector, you can simply reverse the
polarity of the signal coming from that input inside MaxMSP, turning
ones into zeros and vice versa.

The impedance/conditioning aspect can be cured using the Teabox’s
optional ‘expander input’ which conditions the inputs before sending
them on to the interface. The pin-out problem is a simple matter of
redoing the plug connections on your sensor(s).

Why cant you just buy some of the teabox sensors?
