Robo-Tank 2.0 - Updated Controller

[Rob F]

Alright v2 is finally ready, cases are looking good, website has been updated and new manuals are ready to rock.   

Unfortunately I did screw up on the sensor extension, you think I would have learned by now but no, not yet, maybe now...

Originally I was just going to stick with the optical extension but after I got the test board I came up with the great idea of having of having a plug for optical and non-contact sensor on a single port so a user could use one or the other. I waited till last minute to make it and didn't think at all, as I put non-contact socket and optical socket on the same data line there's a pullup and a pulldown resistor fighting each other, dohhhhhhhhh.   Lucky for me one set of ports works as is, the optical side however the non-contact ports don't work unless that pesky little resistor on the optical side is removed. Almost like the old optical extension, in the end the set I have are no different. In a week or two I'll be ordering more boards so it'll be sorted then.

I think I also decided to add a faceplate to the top of the sensor extension. To make it work correctly I do need to add a pluggable jumper so it can be set for one or the other and it would be nice to have a little note on it explaining why dual ports and the importance of not mixing them up.

Here's the various manuals.

This one goes over the controller ports and some diagrams to connect sensors.

Cases can be found here, one of these days I'm going to make this page look better, kind of hard to navigate.

I have 7 or 8 of the old ones remaining if anyone is interested, I'm only blowing them out as DIY kits.

And here's some pics, the power bar hasn't changed, just posting the full package. You can see the faceplate isn't sitting perfectly square, I'll work on for next order.
