you are the best engineer out there! A+ RESPECT

I'm in love with this machine!

Very nicely done... good design. Thanks for sharing.

NICE! I'm going to have to try to build one of those!

Your sorter is very quiet, excellent job! I want to make one, but add a feeder tube for a taller stack of coins, with perhaps a small vibrator attachment near the bottom. I will be checking back to get your additional information, thanks!

Very cool. Nice work!

i love the gravity sorters the best good job.

Haha.. Awesome! What is that, a 20oz soda bottle, a DVD case, and a CD and LOTS of time? That's awesome man..

@Capactiance copper ones weigh 3.11 grams when uncirculated. mine weigh an average of 3.07 accounting for wear.

Where did you get the wheel inside with holes large enough for pennies?

Did you try other speeds of motor and conclude that this is as fast as it can go, or is it all you had lying around?

Nice use of the CD made one like this but I used the feed wheel for feeding the Comparitor

What kind of motor are u using?

That is a neat machine

can you show how you made this

Hey there, I need your help please.. Can you explain to me the mechanism that you considered for the sorting? Does it involve the weight of the coin?? Please reply asap. Thank you.

Does the deluxe edition use duct tape?

is it sorting by weight?

thats kickass dude...

@andrew0901280 you obviously cant load it and walk away,he never droped more than one penny in at a time,he has to wait for it to go almost all the way around b4 dropping another.

Genius! Have you calculated your accuracy?

what motor?

then what? you bring it to a scrap yard? or? where do you bring the copper ones? what are they worth?

Neat device. Okay I understand that it is sorting pennies but what method is it using to differentiate between them?

@18wheeler76 Actually he can load it with a roll of pennies. 1:00

@voidenter Why do you say that? The half cent was removed from currency in the U.S., and other countries have gotten rid of their cent. The most assholish thing the US can do is get rid of the penny as legal currency, and make a law that you can't melt what "used to" be the one cent.

People invest in "junk" silver. These are pre-1965 US dimes and nickles that are 90% silver, or some newer half dollars that are 40% silver. You would be crazy to spend them for face value. But people do not melt them down for silver. They buy and sell them based on silver content. Well, the same thing is happening with copper pennies. You can buy them on Ebay if you like for well above the spot price of silver. No need to melt 'em down. They are trading for their copper value.

is this for sale?

is it weight that determines the difference

Could You please make a tutorial?

make a video on how to make this

@epohnopulse thats not going to happen, the shock factor would be too big. to some.

Sorry, you can buy the copper pennies (wheat pennies for some) above the spot price for COPPER, not silver as I typed above. Oops! :)

How is the MD-80 doing

Can I borrow this?

isnt it funny how we could sit there watching this thing spin around for 30 minutes?

Very nice! How much?

i made one just like this but a little faster, and i wanted to make anoughter one, i got done with that and i wanted to do the same, 4 weeks later i have 15 penny sorters[ i had all the parts laying around the house, i was very bore] well now everyday i stop by the bank on my daily traverses and get 250$ in penny s for 1 days penny sortieing

zzzzzzzzzzzzzzzz

Slow

Can I borrow this?
