Do you love Mario Bros?
Did you always want to know how getting a coin by hitting a block feels?
Or maybe you just want a cool place to store your coins.
Well this is the perfect project for you!

Step 1: Materials

The main items you will need are the coins, I used the coins of my country. Any size would be good, but the bigger the better. Cardboard is also important in this project, almost everything is made using 3mm cardboard. For the sound I used an old 128mb MP3 player. A servo hacked for continuous rotation. If you buy a new servo, it will probably come with a few handles, I you use a old servo you will have to make your own handle. Two springs, one to push the coins up, and another to push the coins into the charger. A small piece of a thin plastic, like the kind used in credit cards. Electronic stuff is detailed in step 10.

Step 2: How does it work

Picture of How does it work
First we have a stack of coins in a tube. A spring pushes them forward. Then a plastic lever grabs them one by one. The servo moves the lever down. And releases it making it push the coin up. It is controlled by a timer (based on a 555) that fires with each hit to the block. The timer must be configured to make the cursor of the servo turn 360 degrees. Also parallel to the timer button is the play button. So you will hear the sound of the coin every time you press it.

 

Step 3: Prepare the mp3 player

Easy step, open your mp3 player and find the play button, solder two wires to it and then solder a switch to this wires, in order to make an extension of the play button.
You have to make an empty folder with just the sound of the coin, so each time you press the button you heard the sound of the coin.
hi could you let me know how much all the materials cost? thanks!


hi pudiste dejar que me haga saber lo mucho que todos los costes materiales? gracias!

does anyone have an estimate on how much cardboard is needed for this?
Noah9722 years ago
Wow! That is an awesome project! One question though, where can I get 3mm cardboard?

Really cool, but how does it know when you've punched it?

look at the switches in the final step

Holy shignizzle, this is amazing! The next thing would be to make it light up for a few seconds haha.

can you make one that is tougher and less sensitive? I have a power level of over 9000 and it's hard not to destroy things.
If the "stop" point of the motor were slightly further round, you could reduce the delay between hitting the botom of the box and the coin coming out. May require a one way ratchet system to avoid the spring trying to pull the arm back again. Excellent job!

Wow, that's amazing!! Congrats on your win!
Can you just make me one?? :P

MUY GROSO! TE FELICITO!! ya empece a comprar los materiales para armarme uno.
me quedo una duda respecto al servo....
1)es necesario uno tan robusto?
2) El trimpot de 10k en la placa de timer para q sirve? es para regular el tiempo que gira el servo de modo tal que pegue la vuelta entera y vuelva a comenzar desde el mismo lugar?

gracias!

No, it was made with the sharpie while painting black the top of the box.
Im sorry but i saw this and i thought this is lame for a grand prize winner... but then i saw that it shoots coins and i thought wow can he get second and third prize too. awesome job well deserved

I'm looking to drive a modified servo with a 555 circuit, but I'm having a heck of a time finding a circuit that I can make work.
I have a few questions about your circuit:
1) What do you mean by a 10K preset? Is that a 10K pot?
2) What might be some substitutes for a tip41c transistor? Is there another NPN type transistor that I can use?
brunoip (author)  txoof3 years ago
1- yes
2- there are several transistor that you can use, ask what they have in the store where you buy them.
Regards, Bruno.
i think preset is not a pot its a kind of pot which cannot be adjusted
txoof brunoip3 years ago
Ah yes, and there lies the problem. I'm in a town with absolutely no hobby-electronics shops. Everything I get I have to order over very, very expensive mail. I have on hand a wide variety of NPN transistors. Can you suggest one that would work with this circuit?
nsutton txoof3 years ago
Id like to know the answer to this as well. I am looking to do a small order from West Florida and they dont have the TIP41C. Im curious if the TIP31A would get me by.
brunoip (author)  nsutton3 years ago
TIP31 may work.

Hey! Acabo de pensar una combinación genial. Tu caja y muchas monedas de chocolate (no se si soportarían los golpes) pero estaría bueno probar.

I had a great idea, I think, your box + chocolate coins = a winner.
Biglion3 years ago
Are those argentinian coins? ;-)

I like this proyect. At first I saw it in Taringa.

How much have you spent on it? / Cuanto gastaste viejita? <--- google translator

A most excellent ible, shows imaginative detail work. I would think this would sell in the USA.
aspina3 years ago
Hola, soy de argentina, y soy nuevo en este tema de armar cosas y me re cope con esto, perdon por la ignorancia pero para soldar el mp3 usaste un soldador normal con staño ?
