Circuit 2
circuit 1

Okay so i stared trying out making circuits and measuring voltage. I need to get to 12v.
So the first circuit I tried. It read like 1.6ish and then i added more pee to see if it had a higher reading. But it didn’t so then I tried taking some out and it still had the same reading. So i came to the conclusions that it is not the amount of pee in each cup but the amount of cups you have. Apparently if the length between the screws and copper wire is longer then it adds to the voltage.

In the pics ive uploaded you can see the reading when there was more pee and when there was less and its exactly the same.

I then added more cups and after 10 (with about 25ml of pee in each) I reached 8.6volts. I couldnt add anymore because I ran out of alligator clips (i only bought a pack of 10).

But yeah so far I think its going well. I just need to get to 12v then I can try to increase the amperage.
And so far with 250ml of urine I got to 8.6 volts, which is with one pee-ing.

So at the moment im trying to design how the battery would look and how all the drainage would work.

So, ive been looking at lots of random interesting sorta gadgets/products on the internet and stuff. and I was thinking about where my project was going and I noticed that all the things I was most interested were like home based products like furniture/appliances/bathroom products ect and just basically stuff you’d use around the house. I guess basically things to make living simpler and easier and more interesting. Pretty much all the ideas ive had so far are that sorta stuff. But a lot of them are more technology based then biotechnology. So Im going to try to look more into how i can incorporate more bio stuff into the things which im already seeing around.
But here are a couple of things which have given me some ideas so far:
This is a watch which monitors sleep patterns and wakes you up when ur in a light sleep: http://www.gearlive.com/index.php/news/article/sleeptracker-watch-review-03221147/
Im not sure how biotechy that one is but its interesting.
I thought this was a cool way to power any disposable products: its a urine powered battery that lasts for about 90 minutes http://news.nationalgeographic.com/news/2005/08/0818_050818_urinebattery.html

I was thinking about the maintenance thing from week 2 homework.
And the easiest thing that came to my mind was not just about having systems which dont need any maintenance, but ones which, when looked after, can have some sort of pay-off. like for instance, if you could use these living systems to somehow make money or something which in a way saves money (ie.growing fruit=saving money). This, to me, would seem like a way to get people to want to maintain these systems. in turn, if these systems are helping the environment/with sustainability, then this can be good.
