00:00:00	but it turns out that the 5volt DC motors just weren't powerful enough to turn that stacking mechanism when it's loaded up with coins so I had to go back to using a stepper motor and as you can see here it works really well it
00:00:14	actually pulls a coin from the bottom rotates it up to the top and throws a coin on top of the stack and it keeps doing that until either the hopper is empty or until the stack is full at least that's what I want it to do in
00:00:27	theory that will all be controlled by the limits and I'll get that working in a later video and if everything works out when this stops spinning it will leave a nice stack of pennies on the desk when I pull the coin stacker up and
00:00:39	there it is I'm pretty happy with this result and we're going to use this stack to pull a coin off the bottom using the coin graer rotate it between the two cameras take pictures of both sides of the coin and then identify it with a
00:00:43	machine learning algorithm that will develop over the next couple of months
