Please see kineme.net for Leopard-compatible patches.
- These require the Phidget21 drivers to be installed.
- Device Labels are specified using POSIX Regular Expressions.
- Due to a bug in the Phidget21 driver, I can’t manually fetch a list of interfaces, and so need to rely on notifications.. So if you change the Device Label regex, you’ll need to unplug-and-replug the Phidget for it to be recognized.
- Both patches are pink “Renderer” patches because they provide output from Quartz Composer — they are “sinks” in graph theory. Given QC’s graph evaluation model, I haven’t yet found a way to make these patches reliably output data unless they’re (improperly) marked as “Renderer”s.
- Both patches should support multiple InterfaceKits of the same or differing types — as long as you specify non-overlapping Device Labels for each. I haven’t been able to test this yet — my second InterfaceKit 8/8/8 should arrive later this week.
Here’s a little test setup, using a distance sensor connected to one of the InterfaceKit 8/8/8’s analog inputs, which — via Quartz Composer — controls a relay output on the InterfaceKit 0/0/4. Beth and Robert built the 0/0/4 into a box of 120VAC receptacles, into which I’ve plugged a light.
Far from distance sensor = Relay off
Close to distance sensor = Relay on
Piece of cake.
