Just another attempt to make schematics, PCB and a photo, available to all.
It would be nice to display them here, but...

I've Got it !
Sending the files as attachments, allows their display, afterall!

Thanks for the suggestion.

Hey, thanks for the pictures!

In re. to if it would work with an RCX, not directly. You would need to use the 4 standard diodes that non-passive RCX sensors need (so that the connection can be in either orientation).

So, other than that, it could be configured as a normal passive sensor?

Sure, if it's an analogue sensor, it's usable on the RCX :)

On the RCX? Yes. EDIT: I mean, as far as using it on the RCX. It certainly isn't a passive analog sensor.

If the RCX was able to source more current on it's sensor ports, it'd be possible to also power it using power from the RCX (as an active sensor).

Xander, for polarity sensitive analog sensors you do need to use the diodes though.

I just took an (un)educated guess :) I bypassed the whole RCX era and went straight to NXT. I figured since it was analogue, the RCX would know what to do with it. I learned something new today and it's not even 07:00 yet!

But here it's being powered by a external battery, isn't it? If not, than what's the "5V" at the bottom right corner?

Exactly. I was saying that if the RCX sensor ports could source enough current, it could instead be powered by the RCX (thus eliminating the need for an external power source).

@Xander, if the RCX connectors were only able to connect one way, then it could be done directly. The way the RCX connectors are designed, they can be in any of 4 physical orientations, and 2 electrical orientations. The diodes sort of cancel out the reverse aspect of the electrical connection when in the wrong orientation.

Ah, okay. That's what I thought, but I wasn't sure.
