I’m sure we are all now aware of the rapidly increasing epidemic that is Diabetes. I myself am part of those statistics. That is just my way of saying I also have it. We’re all just statistics to our healthcare systems. We’re not individuals where they care about how our lives work and if they’re actually able to help or not. They look at some statistics, and then make everyone conform to the average. I personally don’t agree with this practice. Humans are not the same, we are all different. One thing that works for one group of people, isn’t going to work for another group. We need variety in our choices on how to manage our personal lives for a number of reasons. One of those major contributing factors in this is money(isn’t it always?). In North America alone there are many people struggling to pay for their medical expenses and have a lower quality of life because of it. Test strips alone are a huge nuisance on a person who is managing their Diabetes. Knowing this information, and the fact that it also directly affects me as well, I decided to look into other methods of glucose monitoring. Video after the jump.

There have been these crank flashlight hanging around for years, and I actually cannot remember the last time they held a charge. They would light up when you crank them, but the batteries were long gone, or so I thought.
Had all the materials laying around and had a bit of time so I decided to make an 3x3x3 LED cube. Its something I have been meaning to do for a while. Eventually I will move up to 8x8x8 or something huge and more time consuming. For now this is good enough.
The basic idea for this ring was to take a piece of a aluminum to make the ring out of, design it to fit the PCB and peltier, and create a heatsink that mounts on the other side of the peltier unit. Originally I had planed to make this a single finger ring but somewhere along the way my brain had fallen for a 2 finger design; It was much more practical, and surprisingly the PCB I made was the perfect size to fit across two fingers, leaving the heat sink on the side. Oddly enough I have a few ring sizing tools hanging around (thanks to my Grandpa having lots of random tools) so I measured the two fingers it would go on and away I went with a design.
