- What is Gresham's law?
Best copper penny sorter for cheap!
Using an Arduino Nano as the micro controller and some other various components. I wrote a simple program to sort the copper pennies out of the less valuable zinc coins. Once a penny breaks the 1st laser beam the program takes a measurement of the micro controllers board time sense boot and stores it in a variable. As the pennies pass through a magnetic field, the copper pennies pass through slower due to Eddy currents. The zinc pennies are less affected and travel faster. The pennies then break the 2nd laser beam grabbing the board time and doing some simple math deciphers if it is copper or zinc. The cheap zinc pennies go back to the bank and the copper pennies we hold on to. Hence Gresham's law! Once the machine takes all the zinc coins out, you can then go through the smaller copper pile finding the wheat pennies relatively easy.
Keeping it real with pneumatics like a roofer would! Unlike work the pneumatics give it a pleasant sound to listen to while the machine runs!

"They" removed a large amount of valuable currency during 2020 under the guise of coin shortages. Good natured people everywhere began turning in their loose change bins to the banks thinking they were doing something positive in society. The banks removed the silver and copper coins from circulation. Just steps they are taking to push forward the implementation of CBDC's. I agree with your final comments. Anyway, looks like a fun project to complete with your kids. Science and engineering is a valuable knowledge that kids must develop. Knowing how our financial system works is also valuable. Keep it up Brian!
I'm an electrical engineer so this is awesome to see. But seeing you as a skilled roofer making this decently complex engineering project is extremely cool and respectable. Very cool!
Lol thank you! I know, it's been a bad industry to work in because everybody stereotypes you as a worthless drug addict.
@@GrandRoofingInc Honestly, the trades don't get enough respect. They build the constructed environment we live in. Engineers and the trades are the main professions that build and design our constructed environment.
Holy crap. I thought monetary policy was complicated
Lol
I appreciate the stream this evening! You're helping more people than you know. Planting little seeds, that one day grown into beautiful things. It's late here on Eastern time, so I need to get to bed.
I watched this video because my grandfather’s last name is Arduino. I watched once and couldn't process the info as fast as you were sharing it, so I played it at .75 speed. It it pretty impressive that at 3/4 speed you sound like a totally normal human! That helped, but every new-to-me concept that you mentioned led me down a new rabbit hole of learning mathematical calculations, scientific laws, and engineering concepts. I didn't fully grasp how they all worked together and got pretty overwhelmed. So, I tried playing it at .5 speed but then your voice sounded like my grandpa after his stroke, which landed me in therapy to finally deal with those demons that haunted me. In one particularly haunting sessions, I realized that your video made me feel dumb. F that! I was determined to build my own bigger and worse sorter!!! So, I enrolled in that SNHU online college engineering program. They said it was a 4 year course, but I've got other responsibilities so I took the 5 year track. 7 years later, witth my BS in mechanical engineering in hand, I secured the parts needed and constructed my own sorter! The moment had finally arrived! I went to gather my pennies... AND THEY WERE GONE!!! I tore through the house with all the BDE of Will Smith looking for Chris Rock when my family took no time to implicate my now 21-year-old son who, 6 1/2 years ago had sorted the pennies by date, rolled them, banked them, and used them to buy one of those Ancestry DNA test. Well, it looks like Grandma was a busy hippie and never told Grampa Arduino “You are NOT the father.” … so I am back in therapy and have too much student loan debt to afford that new roof I came on your page to look into.
Wazzzz up Bro! Just shared via Twitter! So cool! Thanks for sharing the arduino with me! This gives me a plethora of ideas! Cheers brother! 🍻
😆wth?!
I wish I could communicate like you. My mind and mouth just dont mesh like that.
Interesting stuff.
You gotta love technology
That’s ingenious Brian 👍
I love this. Playing with pneumatic solenoids can be a lot of fun. They are also a staple tool in automation XD. You know what's funny about Zinc, making it into Zinc Oxide (Aka basically zinc rust) is more valuable partly because pure Zinc Oxide has tons of industrial uses. Moreover, for the same amount Zinc you get more mass of Zinc Oxide than just metallic Zinc. 65.39 g/mol for Zinc and 81.38 g/mol for zinc oxide. Most the Zinc oxide in the world is produced by heating Zinc up till it turns into vapor and oxidizes with the Air, and then that vapor is cooled to condense it back down into a fine white powder.
Neat!
You got that right, what's added up top in brain power counts!!!
Hey I'm a computer security guy and a EE by training. I saw cellulose insulation touching a single walled vent flue in my attic, and a few searches and videos later, I wound up here. I had no idea how - now I see you're the roofer in the previous video,,, what a strange coincidence. So I guess, given that I do construction work in my less-than-copious spare time, I'm your mirror-world self :-)
You are a Robert Anton Wilson fan, aren't you? He is always on about the central banks and creating money. Here's a fact I bet you didn't know - basically all banks routinely create small amounts of money. Every time you call your bank and get them to reverse a fee or charge or something, they're just adjusting your balance in their database, but they generally aren't making an adjustment in the counterparty's account. For fraud investigations, by law they have to credit your account while they perform the investigation - so again, money out of nothing. I don't think the counterfeiting laws apply to digital money (which is what the central banks loan), just currency.
Video games are in essence legally creating money - first they make a compelling game with a lot of grind - and then they sell your the ability to bypass it. They sell you the poison and then they sell you the remedy. When they create virtual items and they get sold on secondary markets, that's basically creating wealth for them out of nothing. NFTs are just the latest iteration on that.
Been meaning to create a cat door that will only let in my cat, and only if they aren't carrying a dead rat in their mouth. There's some artificial vision projects out there for detecting dead animals in cat mouths, but not generalized, and I've never seen it paired with an RFID chip reader - might be fun, since you already have the robotics stuff down pat.
Awesome video, professor!!
👍👍👍
Nice. Imagine hoarding $100,000 worth of pennies hoping it becomes legal to melt them. That would be 25,000lbs. Maybe 500 of those buckets. And you'd probably need to sort through 200k lbs or more to get 25k lbs of copper. The logistics are problematic.
you can buy a Ryedale Sorter too
Can you make a build sheet with like schematic and part list
Can you tell me about seconds unwrapped shingles that have no warranty. Sold for $15-20 architectural. They claim they are b grade or seconds directly from manufacturers. Some are bare stacked on a pallet, some have x spray painted across pallet, and some have white plastic wrapping. Even seen some with package torn looking like packaging has been outside for awhile. They are on fbm, OfferUp etc. If some are in torn original packaging or just have an x spray painted on the pallet how often do these wind up as retail shingles to unknowing roofer or diy. Maybe they are a good buy? Or how many home owners are getting them and had no idea all along.
