Anyone ever made a home made coin tumbler? Store bought tumblers are pricey, would like to be able to wash/clean all my old coin finds that I get when metal detecting.

Hey guys, I was just wondering if anyone here collected coins. My brother, and my dad, and I all collect coins as a side hobby. What coins do you collect? What types do you have, and the oldest ones? I have many books for nickels, dimes, and pennies. I just love the feeling when I can open up the book and find it full! My brother and I just bought some old Indian Head pennies, as well as some Steel Pennies from 1943. (During WWII) I have many foregin coins, as well as about 20 Susan B. Anthony's. I have about 10 Sacajawea coins, and a few Kennedy Half-Dollars. I just love the feeling of the profit that will be made in the future. Today I collected about 6 brand new 2007 Pennies, and took them out of circulation. Share your tips, tricks, and cool places to find your coins! As well as your coin collections!

Hello all, could anyone give me some insight to how complex the process of designing a very small GPS tracker which could be used to track lets say a person, which can post its co-ords to map software which is custom programmed etc in realtime. Hypothetical scenario: 1) Tracking someone who is on the move outdoors, only has very small pockets to fit the thing in. 2) The device must send co-ords to mapping software on a computer every 10 seconds maybe. 3) Someone can view there position on the map software in instantly to understand their exact position. Also how expensive would the whole process cost to manufacturer roughly? Thanks in advance and sorry for the vagueness in my question

Saul heard about this sweet idea at the G4G8 conference. It's perfect for an Instructable - hopefully someone is suitably inspired to do it.Take 40lb's of pennies. Drop them all (equivalent to tossing). Collect all those that were heads and put them back in the bucket. Drop them all again, again choose all those that land heads. Repeat until there is only one coin left. This is the luckiest coin in your bucket. Apparently, one guy got a coin that tossed 17 heads in a row...

Acoustic method could quickly catch counterfeit coins.You might assume that counterfeiters only bother with high-value bank notes, but there is a chance that some of the coins jangling around in your pocket right now are fake. If Mototsugu Suzuki gets his way, it may be that jangling that gives them away.Suzuki, a researcher at the Tokyo Metropolitan Police Department's Criminal Investigation Laboratory in Japan, has developed a way of examining coins based on the sound they make.In Suzuki's method, coins slide down a slope and then fall onto a brass block. The sound they make on impact is relayed via a microphone to a computer.Although the human ear cannot usually tell the difference between real and fake, a computer can. Genuine 500-yen coins showed four distinctive peaks of natural resonance frequencies in the 5-20 kilohertz range. This was not the case for fakes; some fakes produced only three peaks, while others showed four but at different frequencies to genuine coins.In addition to helping detect counterfeits, the sound data could be used to build up a database of fake coins, suggests Suzuki. This might help law enforcement officers to prove how many coins one counterfeit operation is responsible for. This would make for an awesome Instructable! Start with these two Instructables and get dropping pennies! https://www.instructables.com/id/Build-a-dsPIC-Oscilloscope-and-Spectrum-Analyzer-/https://www.instructables.com/id/Low-speed-AVR-oscilloscope/

This is my knex coin pusher. before you start begging for instructions i dont know if i will post but if to many people struggle to build one i might post instructions, because im not posting instructions i have taken extra+ photos of the mechinism and how it works. i had to use white connectors because i didnt have enough coins, if you do this the connectors wont fit down the slots so you have to just place them. i would make a video but the batteries in the moter died. it has a secret gutter on the side that real coin pushers have and the monney goes to the owner of the machine, if you dont want this you can push the orange connectors on the right down and it blocks it out. this one is bassed on bezempje95 link to his one http://www.youtube.com/watch?v=5dOPa1-zDUI he has more infomation on his in the link in the description.(if you havent looked at his you need to because its so awesome). if you cant build it from the pictures put a comment saying: "POST +1" with the capitals and if it gets over 15 before christmas i might post it.

I was looking for something else, and found this site by local (he lives about twenty minutes from me) Maker Extraordinaire, Tim Hunkin. He has a main site, as well: http://www.timhunkin.com/ .Tim is best know in the UK for an old TV series "The Secret Life of..."

Need help finding a particular instructable, friends. I would almost bet body parts that I saw an instructable here that had the following process to it for making a custom fantasy coin or medallion: Use the underside bottom of a paper coffee cup-mix up a portion of Bondo and fill the bottom recess with it. When Bondo hardens, pop out the round disc, paste a paper disc onto it then draw out your coin or medallion design. Carve out your design with a dremel or similar, make a silicone putty mold, then when mold is dry, pour pewter or zinc to make a custom coin. Darken and polish. I know I've seen it, I'm wanting to stick it in my favorites list so I don't lose it again, and I especially want to thank the author for coming up with such a simple process for a custom medallion. Can anyone help me?

I've been Geocaching for a while now and I wish to make my own Geocoin. I looked around all the "official" sites, only to have my head explode at the prices. $1,507.38! That's more than my high speed camera!Three for $27 with the fine print stating that you will more than likely end up paying $360-$540! Is it too much to ask for one or two custom coins at a cost in the lower double digits?! Why would I want to pay so much for something that will travel around in caches subject to anyone's whim? My question is, how can I make my own custom coin? The tracking code will be provided by one of the Travel Bug Dog Tags I own (at least those are cheap). Any help or advice will be useful, just let it be known that I am absolutely terrible at molding.The desired end result should look something like these rough sketches, front and back (followed by an example coin that I picked up and moved. No tracking numbers, no cheating!).

I'm trying to build an electrically controlled coin dispenser (all the coins will be the same type). I have a metal tube -just the right diameter for the coins - mounted vertically, with a piece of wood horizontally at the bottom. There is a gap between them of approx 1mm, just enough for a single coin to be visible. I've been experimenting with using a solenoid to swipe a coin from the bottom. Rather like the image here: https://www.instructables.com/answers/Petty-Coin-Bank-Design-Coin-Dispenser-What-shou/ Solenoids aren't cheap, and I was aware that the weight of the pile of coins (I'd like to be able to hold around 100) would mean it needed to be fairly powerful. In the end I bought some cheapo solenoids from ebay (around $7 each). They are rated 2A and have a hold force of 20N - this seemed a lot more powerful than I could find elsewhere for even 10 times the price. Given how cheap they are, I could even use two in parallel if I still need more power. I'm using coins with a 20mm diameter, but after the solenoids arrived I realised they only had a 10mm stroke - obviously not enough to fully push the coin away. I've tried using the solenoid to pull a lever, but this doesn't seem to work very well. Previously I'd also tried a stepper motor linked up to a disk with a coin-sized hold cut on it, rather like this: https://cdn.instructables.com/F49/GK0I/H703O9VD/F49GK0IH703O9VD.RECTANGLE1.jpg That worked pretty well but was very slow - it would take 3 or 4 seconds to dispense each coin. So, I'm looking for a bit of advice. Would I be better off splashing out on a more expensive solenoid with a 20mm+ stroke? Am I approaching it the wrong way?

I have a very good coin collections my father left me. I'm not really into coins, and would like to unload them to someone who has a good knowledge about coins. He collected these coins while how was in WWIi. Here is a description of what I have: I have around 20 silver dimes that are so old, the dates have rubbed off. There is one dime dated 1907. I have one Morgan dollar-date 1917. I have several buffalo nickels. I have the following silver quarters: 1952' 1954, 1947, 1942, (2) 1943, 1956, 1941, 1946, 1944, 1942, 1954, 1963, 1961, 1957, 1950, 1944, 1960, 1924, 1907, 1951, 1964, 1936, 1955. I have several silver dimes, nickels, and quarters where the date has been rubbed off. I have not "clean" the coins or "polished." I would just like a "ballpark" amount of the coins I have....

Question about flashing red LED: I have a simple circuit--switch, battery, resistor, LED. Today, when I clicked the switch on, the LED came to life very slowly, as of it were fading in. I have never seen this behavior before. Is it the battery? (3V, 2032 coin cell and 100ohm resistor). Thanks.

I'd like to make a change sorter/counter that I can use with my PC to figure out how much money I have in some 5 gallon buckets of change that we gathered while cleaning some old fountains. (Yes, they said we could have what we found under all the gunk as long as we got the fountains clean and back to working order.) I want to be able to dump some coins in a sorter/counter and have my PC tell me how much there is in a given bucket of change. I don;t want to use estimating techniques like calculating the approximate number of coins of a given type by average known weight of the coins. I want an actual tally - a count - of all coins of each type and unknown coins (slugs). Any ideas?

So my friends and I are planning to sell, well...things (I'm not going to give out any details as of now, later) that incorporate small round metal disks. now in all of our prototypes weve used coins for our purposes and they work great. but for what we make we need to cut and sand coins in different ways. and my friends always tell me "its illegal to change money in any way." But I've heard that its only illegal to modify money to change or duplicate the amount its worth - like making a penny into a dime is illegal but making a penny pac man figure isnt. can anyone clarify this for me? I'm fine doing illegal things like modifying coins for personal use but if were going to sell these I want to be a little more clear as to what is going on.

Hello Everyone! I'd like to ask your help in making this circuit. I want to make a simple circuit that emulates a push button switch: When powered on, the circuit will trigger a switch. When powered off, it will trigger the switch again. I'm thinking of using this for my home made coin operated PC. There are various options for the coin operated PCs from shutting off the monitor or keyboard & mouse to software triggered. But I'm thinking of using the stand-by or sleep option of the motherboard. My current setup is a coin slot that is connected to a timer circuit. When coin is inserted the timer is activated and a relay will turn on. I want to put the circuit to this relay output and connected to the pwr button of the PC. Hoping for your assistance,

I have 2 games (and a half), first: runescape.com this is an adventer MMORPG. You battle different types and levels of monsters and characters. You can strive to be the richest or to be the strongest. Second: hflhotel.4t.com this is a habbohotel.com fan site with its own habbo like interface. You log in and you automaticly get 800,000 free coins. In habbohotel.com you have to buy you're coins for 10 cents a coin. That can add up! 50 coins is $10, so I recomend what they call, a retro habbo. (I am sorry... this website had been moved to a different server or deleted. I am sad too) In a half: habbohotel.com I dont recomend this game unless you have 500 dollars laying in a dust gathering pile in you're tool shed or you will have the least of fun!

Have you ever wonder were, phrases come from like " That's what she said " or "See you later.......not if I see you first" or "Well, there's your problem!" I think i may of coined a phrase, but of course I can't prove it " Its funny cause its true" I even heard it on TV the other night, I have been saying that for years. Anyways today after a student made a mess I gave him a mop and bucket and told him to clean it up. After 20 minutes I came back and he had managed to make the mess about 100 times worse. I was very annoyed with him and I was inspired to say "Never send an idiot to do a job a monkey could do" Anyway there is, If it takes off I will now have proof that i said it first on 20 april 2016 So whats your favorite phrase or one liner? Maybe you could come up with the next "That's what she said!"

What I want to do is keep score with my coin soccer game. I will have 2 metal contacts in the goals that when a coin goes through it will break contact and send a signal to the Arduino having the contacts allways HIGH and then when its LOW, it changes an 7 segment LED. I am very new to programming and the C language. I think I can write the whole IF and ELSE statements but I don't know how to make the LED display change. I need the LED display to change after getting the signal from my Arduino by going up one number. It is a single 7 segment display. Can someone help me with the code for that? Thanks in advance.

Chinese knots are, in some ways, similar to Celtic knots. Each knot represents a particular traditional Chinese form, and in many cases are representative of Buddhist precepts like the continuation of life. Chinese knotted jewelry usually incorporates a main jade or stone centerpiece and jade, stone, coins or glass beads. The cord from the knots usually is extended upward to make a lanyard for a necklace, but with some bracelet styles the knot or knots are extended around the wrist with a macramé style knot. Chinese knotting was nearly lost as an art form. In recent years, several books teaching knotting techniques have been released. The cord used in making the knots is readily available at craft or fabric stores. Josephine Knot (Chinese Double Coin Knot) http://www.bridgat.com

I need to design a programmable flashing light source for small models. The Arduino PRO mini looks perfect, but how many white LED's can I run on an Arduino PRO mini 5v? Am I right in thinking that a 3.3v mini will not power them? I would like to use at least 3 LED's but 6 would be great. It will be powered by either a 9v, or coin cell battery if I can use the 3.3v version. I assume I can only use the coin cell on the 3.3v version, but use a 9v battery for both versions as long as I connect to the RAW input is that right? Cheers.

I hooked up a 5 mm LED to a mini push button on-off switch. However, when it is in the off position the color is still bleeding through. Could this be because the LED is too strong for the switch? I am powering it with a CR2032 coin cell battery.

By incorporating a metal detecting apparatus, the Create could constantly trek through the house collecting lost coins, jewelry, pain-inducing metal debris, keys, anything having metal and being small enough for the Create to collect. Larger Items should be easy for you to spot anyway.

Hey everyone, I can't imagine that this question hasn't been asked before, but I must be using the wrong keywords. I used a small electric crucible (for lead and pewter) to heat up pewter and pour it into a coin shaped plaster mold. Truthfully, I'm pretty pleased with the level of detail, but I've got some 'burned' colored discoloration on the coins. I've tried gently washing with soap and water which got off some of it. 1) am I doing something wrong to produce that coloring? 2) will silver polish clean it up, or will it damage the pewter? (almost certain it will be fine, but thought I'd double check) Should I just be scrubbing harder with soap and water? For whatever reason, the image uploader isn't working. I'll try to get one into the comments after I post this. many thanks!

Souldn't be too hard right? Or is there something obvious i'm over looking
