About:
      Finally, a cooking aid that can not only help you continuosly stir your meals, but can also be programmed for
specific stirring periods, particular speeds, and it takes up virtually no counter-top space in your kitchen.
It plugs into a standard 120v outlet, has detachable stirring attachments that vary in shapes and turn radius,
and the whole thing can fold up for easy storage. Because of it's kitchen surface-top effecient range strattling
design, however, there is no need to pack it up after every meal, just leave it in place! For cleaning, the
detatchable stirring attachments are dishwasher safe!

      In these images (from left to right) you can see the Krillstir fully assembled, folded up, and over the range.



Initial Design:
      Here is the Initial Design Schematic and the final circuit revision implimented on a breadboard.



Assembly:
Putting it all together wasn't as easy as you might think. It actually wasn't straigt forward at all. In fact, there
were quite a few challanges that needed over come and the occasional design flaws that required change.
      For example, when using gears at perpendicularity, it is crutial to get their positioning perfect, so getting them
lined up and mounted with out causing unintentional friction was very challanging. Another, how can you make the lower
feet fold up in such a way that you don't sacrifice any lateral stability? I must have gone through at least 3 different ideas
for the folding legs and feet; this design proved to be the most stable. And my favorite design choice, where to mount the
buttons. If you place them facing the user, you would push the whole unit back with each press, so they needed to be in a
place where the forces were directed down.

Here are the buttons used to change the mode and alter the values (up/down). This module came from a disregarded printer.

The wires attached to the button module were actually metalic strips arranged in a single ribbon cable. I had to get pretty inventive to utilize it.

The inside of my power supply module. This board came from a recyling pile! The only thing it needed was a new fuse.

The completed power supply module.

The front of my custom made Main-Board. It's sporting a 16f872 PIC processor, a seven-segment display, tons of indicator LEDs, the solid state PWM mosfet motor driver, some power stabilization circuitry, and a piezo buzzer for audible feedback.

The rear of the main-board.

The main-board mounted to the plastic insert in preperation for the insertion in to the pipet box.

Name: DK Time: 09:08 PM Date: May 04, 2009 Comment:     haha, well the actual product would be made from plastic, so no worries of splinters there, and the wiring, you must be talking about the breadboard, it's because I use the same jumpers over and over again, so they are all the wrong lengths, but the final soldered board looks prety nice I think.

Name: DK Time: 09:20 PM Date: May 10, 2009 Comment:     nyan - good observation, I thought about the steam too, and actually yea, the boxes are laboratory pipet containers, they are water proof. Em - I've only used it a few time so far for real food, it actually comes in handy the most for brewing, cause you need to stir the brew almost continuously for 2 hours.
