An oscilloscope, EXCELLENT :D
The data line should idle at +5v. When you send an FE C8 02 command it will perform many transcations and resets on the bus. (BTW I'm hoping that you have a digital scope, since an older analog one is kina useless here). Setup the scope to trigger with a negative ...

Just to add on a little: The LEDs in a fan that shine on the blades are VERY noticable when it comes to using PWM to the fan. Normally the LEDs would be stationary and they would just increase or decrease in brightness, the flicker would be too fast for the human eye. However since they shine on a ...

First off, I've never used the rabbit core, but I'm hoping that what I say is generic enough that it will apply to all microcontrollers .

None. You access the display through serial and use the displays 1-wire driver. For example to get all temp probes to get a reaeding ready, you transmit:
FE C8 01 01 10 00 CC 44 (explained in the 1-wire tutorial)
VIA the serial port to the display. Then the display will take care of the 1-wire bus ...

Screen gallery
ALL RIGHT ALREADY!!! I'll get it back and running. For the record I've been quite busy here (as the one who designs the units AND keeps the networks up), and I did assign the gallery a lower priority. But I will do everything in my power to get it up and running today. Right after lunch

NEW SERVER!
Well it had to happen some time: our old server died. This pushed up our server migration plans a little bit. Good thing we had that quad Xeon waiting 8) The management appologises for any inconvienence.
Oh and for those who would like to know, this completes our migration from windows to a 100 ...

WOW :o I've got to agree with everybody else, this case is way too cool. Amazing idea using just peltiers and a heat sink to cool the fluid. Way to many questions to post on the forurms all at once, so here are my biggest ones:

Off hand, I don't think there are many "common" wires. Pins 15 and 2 are both Vdd, but that is about it. The only ground is pin 1. Although a quick glance at the schematic tells me that pins 7, 8, 9 and 10 aren't used, so you could omit those. This leaves you with a total of 11 conductors.
