All right, this may already be mentioned, I wasn't able to do a search for some reason, but I figured I'd just post this anyways.
I've built a little device that uses some seriously strong magnets that interact with the copper pennies, and not the zinc pennies .. well for the most part. This is all thanks to a little property called paramagnetism and it allows me to separate the copper from the zinc because the copper pennies get slowed down and fall into a container because they are attracted to the magnetic fields.
The first penny I drop down is a copper penny, the second one I drop down is a zinc penny. Notice how the copper one falls into the pot, while the zinc shoots away.
If you are interested in science at all, please check out my site.. You must be logged in to see this link.
Thank you in advance! and please let me know what you think of my copper/zinc penny separator. Clearly this is a lot cheaper then one of those 500 dollar ones, and I'm sure with a little modification - such as coin addition, it should be able to work a lot better then it does now - even though it seems really pretty good at keeping the zinc out of the bucket, and dropping the coppers in.

| Been working on same for 5 years or so. Works well. Have prototyped approx. 15 types of sorters based on this principle. It works well. Have sent some prototypes to realcent members for review, good results. |

Was going to say them same, Andy's new machine is great and is very accurate as long as its level. I imagine any machine that works on this principle is sensitive to any variance since it dosen't have a high tolerance for the mechanisms that make these work.
On a different note, its always great to see someone tinking actually work. I dreamed up many different plans myself but figured I would just let andy do the work if mechanical means became neccessary for my sorting operations. congrats on the machine!!

Ha yeah, I hope it can become a nice forum like this one someday with this many topics and members. I could use some help haha so feel free to join :)
Anyways, I think if it were modified this would be a cheap - no more then 10 dollar method of separating coppers from zincs. Also! if you have quarters.. it should work for getting the silver out as well with a bit of adjustment since it would have different properties then the 25 Ni & 75% Cu ones... but I doubt there is any silver left in the currency :(
Oh also.. why not use a vibrating surface of the right frequency for the copper coins, but not the zinc, if you are going to be making them to do it in a bulk-ish quantity?
At least.. this seems like a possibility to me.
Oh right, and you should be able to process them as fast as they can roll down the tube - I assume that is close to as fast as you can sit a penny in a tube... I'd like to get it so its more automated though, perhaps with some sort of funnel? |

Hey Magna, is your sorter one at a time or bulk sort? (Want to say auto feed but depending on the mechanism...) I'm interested. Post or PM more!
Indie: Nice job, good start. Figure out how to feed a roll or more at a time with few errors and few jams and you'll be in business! |
That's not a dollar, mate...THIS is a dollar.

| Anyone have any ideas how I might go about doing that? I'll brain storm a bit and see what I come up with, but I'm pretty much stuck when it comes to this part of it. |

You would need to meter out the coins because if they go in several at a time the coppers and zincs might knock each other into the bucket incorrectly.
There is silver out there but you would be faster to edge check it. I'll check out your forum - but this one is pretty strong and it is working great. Why not just join us and contribute here? |

| Several of my machines are based on the cheap $10 coin sorters from walmart (Money Miser) and I put a slide under the penny hole. Coins slide down the steel channel and gain momentum. At the bottom of the slide is a supermagnet. The magnet acts on the moving coins to induce an eddy current... anyway the copper slows down more than the zinc. The copper thus does not go as far as it leaves the ramp. Think of a ski jump, my channel is at 45 degree angle. Zinc will 'jump' off the end and land 12 inches away, copper will be slowed and land only 6 inches away. I put two small bins on the floor so that the bin walls are at approx. 9 inches from the end of the channel. Copper falls in the closest bin, zinc lands in the farther bin. I just got a decent videocamera and will try to make a video. The battery operated sorters Ive made sort at a rate of a dollar a minute. The manual ones 'hand feed' sort at a rate of 25 cents per minute. Total cost of making a manual sorter could be less than $10 for the channel and magnets. Ive made most of them out of a wood frame to hold it together. Ive also made the same setup for nickel sorting, its a little more sensitive but my 5 year old ran it and got 95% accuracy sorting US, Cdn Nickel and Cdn Steel into three bins at the bottom of the rail. |

Indie, congratulations on your inventiveness. This would be a useful way to distinguish the 1982's inexpensively 
Mega congratulations on your site, Dude!  Incredible logo pic, I'm envious. I think that your site serves a niche that is not covered here. You might want to consider adding climatology and geology and astronomy, lots of tornado chasers, amateur weathermen, mineral hounds, and budding Galileo's out there. Think of your science regimens (think hobbies, then work backwards) that have mass participation, then offer them a forum to meet and soon you'll have a bustling site. Congratulations!  I'd join myself, but I'm a dingbat when it comes to the sciences.  |

| And (finally?) how about Virology and/or Bacteriology (may fit within Biology but deserves it's own string). Just think, when the Marmot Flu pandemic hits your site could be the place to get the latest updates. The Centers for Disease Control would have your site linked as their home page.

| Kinesiology - people could discuss their workout routines, anabolic steroids, sports physiologists could chime in. Medicine - all the homeopaths could contribute their home remedies and herbal concoctions. They could discuss preventative vitamin usage or nosocomial sequellae. Gosh,the list is endless, isn't it? |

Wow thanks guys! I really appreciate all of these suggestions and I'll be sure to work on it more when I have the time. When it comes to forums, I've never met as many people so willing to give suggestions and compliments.
Thanks!
Also.. for the 82 pennies, you could always hit them with the wire cutters. Just till you get to the inside of them. Zinc cuts more easily, and would obviously be shinny while copper would be harder to cut and look like copper. |

I think Penny Miser feed is pretty neat:
You must be logged in to see this link.
(And I hope that his product will be fine-tuned, I think it has potential with the weight method.)
A vertical style feed might work for a mag sorter, pennies are dumped vertically into a tube, space at the bottom of tube could be 1.5 times times penny height and a spinning wheel with sticks/spokes knocks the bottom penny out and into the shoot. |
That's not a dollar, mate...THIS is a dollar.

If you added a magnet to the bottom of the weight feed, you might be able to make the copper penny appear significantly heavier then the zinc penny - this might allow for the instrument to be less temperamental, and not need to be as sensitive.
I've been talking with some friends, and using frequency sounds more and more practical.
Edit: As for adding all of those topics.. maybe with in time. I personally feel it would be best to create a site that has some strong foundations, and then from there work my way up to more and more. Plus I want it to be mostly science related - which is physics, chemistry, and biology.
politics and that sort of thing is an easy one since the chemists have really been beat repetitively by the government, but still this may not happen, and if I do make a section for it, it won't be till later. To get what I mean by the chemists have been beat by the goverment check out: You must be logged in to see this link.
it is upsetting to me what they're doing to our freedoms. |

We have an aluminum seperator like that at work. Ours is just a lot bigger.  |
If your percentages are low.. just sort more. If your percentages are high.. just sort more.
Now selling Copper pennies. 1.6x plus shipping. Limited amounts available. |

Very interesting video.
I've been wondering about passing them through a plastic pipe with a copper coil around it.
I've made magnets float in a testtube above copper coils that were wrapped around the test tube.
Another idea I've had is to use the motors found in pencil sharpeners, since I believe they create a rotating magnetic field. They might be able to do something.. but I don't know for sure.
Ha who is Mr. JMD.? |
