Coin sorter

Has anyone ever made a coin sorter? I was thinking of making various
styles of coin banks as Christmas presents and thought I might add in
a coin sorter to some of the designs. The simplest looks to use a
ramp that is tilted to the side slightly. The ramp is "L" or "J"
shapped in cross section. As coins roll down the ramp they ride along
the vertical part of the L, falling into holes or slots just big
enough for the denomination of coin; holes are arrainged smallest to
largest down ramp. Have to be very precise to cut slots/holes to sort
between pennies and dimes.

Ever thought of adding an electric motor to it to allow the user to simply
dump the change in and let the project do all the work? I've been thinking
about ways this could be done simply and easily. I think a sweeping arm
could be used to orient the coins and then push them in to the sorting
slot. Might have some trouble with the coins jamming though...

That reminds me... my little sister wants one of those marble drop games.
I probably ought to whip one up and give it to her for Christmas.
Methinks the hardest part will be the mortises in the end.

That could be an interesting coin sorter, too. Just cut slots for each
coin at the end and have a cup there to catch them. Hours of
entertainment!

IMHO, of course--I think you should take into consideration whether your
work on this will be appreciated and cherished as much as if you built a
fine box. Personally, I like dropping my change into a bowl all at
once. OTOH, my dad enjoyed using the type of utility you describe.

I think it's a darn *interesting* design exercise! It seems like a good
one for an engineer (which I'm not).

Thanks for the reply. It's as much a design exercise as a serious
project. Like all gifts, anything I give away is freely given and the
recipient can do whatever they want. What they do/how they act
definitely will determine the *next* gift (and if there *is* a next).

Really cool idea.

To create accurate slots on such a small scale, it might be easier to
laminate the bottom rail with the first layer in short pieces that
leave the appropriate sized gaps. Also, I think some study of the
physics might show that having the slot be ramped down a bit and
actually be at an angle.

I'll try to d a sketch of my idea and post an image.

Sure, you could do this. I've even seen youtube videos showing a Lego
"Mindstorm" robot kit that sorts the coins.

I'm looking for something easy/quick to put together. I was also
thinking of just going hog wild and building one of those Rube
Goldberg style contraptions with belts and pulleys and gears and cogs
and LOTS of moving parts. Kinda like one of those "marble machines"
with each coin taking a separate path through the machine. That might
be for *next* Christmas though...

Here are some youtube videos. The first shows the basic concept I
have in mind. The last one is the idea like you describe, but with a
display to indicate how much total value is collected (a little beyond
the scope of this project).

They all look fairly easy to build.

Never made a coin sorter, but I think that would be a pretty cool thing to have. If you
find a design that works out I'd be interested in it.
