What's pink and white, and looks a bit like a short alien under stage lighting, talking to a tall man with a diode for an upper leg, and a friend with a paper bag over his head?
Nope.
Too much Christmas spirit.
120 Things in 20 years - As at 2012 12 24 23:56 my demand feeder actually works (if you include a light where a motor should be as "working" (which I do)). I declare this point in time , an Official reasonable electronics success milestone.

I found out what was wrong with my motor.
I'll start that again.
I've been having trouble with my motor.
I opened it up and found what the problem is.
Too many parts inside just rattling around doing nothing.
I'm trying to explain to them that everyone has to pull their weight, otherwise nothing gets done.
So far they are ignoring me.
It's hard to fix something when you have no idea what it looked like before it was broken. Firstly, the bit of metal on the end of the yellow wire has to fit through a hole that's half the size of the bit of metal. But it did just fall out through that hole.
Clearly someone's being funny.
There are two bent bits or copper that look like they make contact with the shaft, but I cant see how they could without wearing out, But then, they are actually worn, or at least they look worn. but if there are magnets on the outside that don't have power going to them, and a rotating shaft with copper coils that gets it's power through these copper bits, why not just build the thing inside out, with the coils on the outside, stationary bit, and the fixed magnets on the inside. That way you would avoid the need to put power through a rotating shaft.
I must be missing something

I've started work on the electronics and programming of my new demand feeder.
I also found my cardboard fish from the first version demo on youtube, so I thought I'd re-make the video with the new chip and this time, a counter that flashes the number of illegal attempts to get food. There will be another counter to flash feeds and a few others.
But for now, here is where I'm at so far....
I'm feeling a lot more confident this time with a little better understanding of the electronics involved.

I've been busy.
I've been busy learning how to create a plan, and a circuit schematic to go with the plan.
It looks like this, and I think it might be finished.
I now know a stack of stuff that I didn't before.
Things like...
It's ok to not connect up the earth (0 volt) wires in a schematic.
You just label them as earths, and leave them hanging in the wind.
It actually makes the diagram a look a lot better to read. (thanks SuperVeg)
When you make a real version, all those earths, are connected to the power supply's negative terminal.
So now that I have a plan and a circuit diagram, my next step will be to build a working model on a breadboard, then solder the real thing together.
I've already started.
I've also started to write some of the required software.
