The worlds bee population is in the process of being wiped out.

Its called "Colony Collapse Disorder",  which is the kind of name doctors tend to give things when they have no idea what the problem is, but want to be able to refer to it in an unambiguous manner that makes other people feel they know what there talking about.

 Colony Collapse Disorder, or CCD is wiping out VERY large numbers of honey bee hives. People that keep bees professionally have closed up shop after losing all their bees.

A while ago, a clerk at the patent office named Albert said, "If all the bees were to disappear,  humans would have 4 years before we were wiped out.", but as far as I know he wasnt a bee expert, but was a very clever man.

The reality is that bees make food grow. almost all our food crops rely on the honey bee to make their fruit, nuts and seeds. Without them we will either learn to eat grass and ferns, or die.

In the last half of this summer, we have not seen a single bee.

Ive been looking for them, and Im pretty good at looking.

I hand pollinated half my cucumber flowers with a small artists paint brush, and left the other half to nature, and not one of natures flowers bore fruit.

Not one.

Im trying to arrange some native blue banded bees to try to fix the problem.

Some time ago I set up a time lapse photography shot of some cucumbers that I thought I had hand pollinated, but half way through the shoot, I realised I had the memory stick that was for the camera on my desk.

Oh well. At least it wasnt as big a fail as the idiot that coded the little beep noise that tells you its working. Their design work means the device continues to make the Ive just taken a picture "beep" even when theres no card in the device.

Clever.

Anyway...

Heres some time lapse of the second setup where I used the plants that were not being hand pollinated. Pay particular attention to the 3 already formed little cucumbers just to the right of centre. (sorry about all the black dead space at the end, youtubes edit says it doesnt exist so you must be imagining it just like me) ...




youtube is giving me some grief. The clip works around 50% of the time in the different ways I test stuff.

This might work http://youtu.be/z85OlJScCEE

If its not fixed soon Ill redo it.

Ive had to make a few compromises with version 2.0 of the demand feeder.

One is that Ive re-written the code and made it a lot more simple than it was originally. Ive still got the old code, and Ill use it and post it when I make it a little better, but the full version resets each day at dawn as one of the overfeeding protection measures. I only have two silver perch in a 100L fish tank, with 300L of filtration media, so they can have as much feed as they like. To encourage the pressing of the button, Ive made it so that they only get a small amount of feed each time, but they have the opportunity of more feed after only eight minutes since the last feed. The point of making a simpler version of the software was so that it would keep a running total of all events like the number of times the fish have hit the feed lever when the light is lit, and the number of times when the light isnt lit.

The fish pressed the lever only once in the 24 hours since I added it to the system. This may have just been a tail swipe, but it would have delivered feed, so some reinforcement of the behaviour of getting at least near the lever has begun!

It wont take them long to get the hang of it.

I ran the camera until the batteries were dead last night, but the hit must have happened some time since dawn while the camera was on charge. To solve this two hour filming limit, I created this.

Its a camera taped to its battery charger, that is in turn taped to a tripod.

I plugged it into the earth leakage safety switch that the rest of the system is plugged into.



It blends in a bit with the actual feeder, but thats the feeder with the birds nest of wires sticking out of the back of it. The orange looking light under the camera is the LED that tells the fish feed is currently available. The red light at the top is the power on LED, and the yellow one is flashing out the number of feeds allowed in a day (even though the thing no longer resets after a day, so really it shows the number of feeds allowed ever). There are also LEDs that flash out the number of feeds so far, the feeds remaining, the number of attempts made at the lever when food isnt available. That is when the feed LED isnt lit, because they just fed recently. And one more that flashes out the size of each feed thats delivered. The size is measured by how long the motor is on for, and doesnt actually represent the amount of feed, but on average, should spill a predictable amount each time. Currently, they would get around 5-8, 3mm pellets each time they hit the lever.

Hopefully, Ill have some video soon.
