A unique Version of the DIY Bin
So I have a unique case in that I am converting lots of fruit to worms. I have a serious problem with water that I had to take care of and I am using cheap materials that I can get past my wife without raising alarm. Also I have found that the ramp concept is good but hard to construct in the inside of a tub. This is the design I have so far.
I believe the key to managing the exit of the BSFL is understanding that they are blind. The following rules can be applied.
1. BSFL will continue in one direction until they meet an obstacle (be that obstacle food or any other slight bump)
2. BSFL tend not to cross acute angles that are sharp. (rounded corners are another issue)
3. BSFL favor a right or left turn over raising their bodies up (they like to keep as much of their body in contact with a surface at all times).
4. Dark BSFL go towards dry. Light BSFL tend towards moist.
5. Any BSFL can climb almost any container when wet and presented with only obtuse angles to cross. (any angle presents the potential for the BSFL to "scan" around that is feel for a potential new direction to go in)
6. BSFL want cover and so tend to crawl into cracks
7. BLACK BSFL seem to prefer going against gravity as apposed to down.
8. All BSFL run from the light. Whites more than blacks.
BSFL that are ready to go to the next life fall out of the holding wash basket into the tub.
I put playdoe between the stick and the tub but made sure to scrape away any playdoe that was sticking out (bump issues and possible makes rounded angle). I am using playdoe because it is easy and available. I have not had trouble with BSFL digging into the playdoe only going in the joint between the playdoe and another object.
The single stick diverts the BSFL that are circling the inside of the tub above the moisture on the inside of the tub. The BSFL feel to the right and the left to see which way to go. Black ones tend to go up. (some do go over the stick, I may need to put future board on the stick). They come to the top of the tub and then they feel again they see the ledge and follow it sticking to the playdoe. When they reach the ledge they try to go to the underside but the tube edge does not allow them to fold their body around crawl under the ledge and they fall into my waiting cylinder.
I put cloth in the cylinder because I found the BSFL like to feel safe under something. It is the rainy season and if a BSFL is determined to get out he can. I had a few nights where I thought I was going to have a great take but then wake up to find that they had all gotten away. I then started to put flour in the cylinders but when the numbers are great that does not deter them either.
This design is not good when there are a lot
of BSFL exiting at the same time because BSFL can act as obstacles to other BSFL thus changing their trajectory. (however this situation is less prevalent in this design over the ramp design because with then ramp there is a larger area that is close to the top of the tub and so their is more are for alternative paths up) I believe the cluster-f**k situation is a problem in most designs when there is a mass exodus. (this design seem to be a minimum, my cluster-f**k occurs when they are deciding to let gravity do its job or not-- they pause at the edge) Once a BSFL creates a path up the side of the tub because his friend redirected hit trajectory others ten to follow him up.
