Step 7: Prepare the top

The top of the box is the main piece of it. It is where almost everything is attached. Be sure that the hole for the coin is big enough for a coin but small enough that it won't let two coins out at the same time. Use the image as a guide for cutting your shapes. Glue everything and let it dry.
<p>I know I'm reviving an old post, but I'm almost done doing this project on an Ardunio. The only reason I'm using an Ardunio is I don't have a MP3 player that will work as easily. <br><br>Anyway, I have all the electronics in place, but I don't know how to get the servo to stop in the same place every time. I'm considering a stepper motor, but I don't know if it will have enough torque. Also I think using a stepper motor will make it hard to use batteries for this project.<br><br>http://forum.arduino.cc/index.php?topic=234273.msg1696696#msg1696696</p><p><br>Please help. I'm trying to get this done for my son's birthday in July.<br><br></p>
it is a servo hacked for working as a regular dc motor. You have to make a timer and make it spin for a limited time. That time is setted by the potentiometer on the 555, Im sure you can make something similar with arduino.
hi could you let me know how much all the materials cost? thanks! <br> <br> <br>hi pudiste dejar que me haga saber lo mucho que todos los costes materiales? gracias!
amazing idea!
does anyone have an estimate on how much cardboard is needed for this?
Wow! That is an awesome project! One question though, where can I get 3mm cardboard?
awesome idea <br>
this is amazing!!!!!!!!
Really cool, but how does it know when you've punched it?
look at the switches in the final step
Ah, I see.
Holy shignizzle, this is amazing! The next thing would be to make it light up for a few seconds haha.
Or change colors when it's out of. Coins
Soy puchacho, De Taringa, Buenisimo tu sistema. <br>I&acute; Am Puchacho, From Taringa, Good sistem.
Holy...!.!!!!... WOW awsome <br>
I would LOVE to make one of these! and i have read most everything and think i can do it. but i dont get what to do with the things in pictures 10 through 14. could you help me please?
Hey, i would love you to add this to my group! Great job!<br><br>Here's the link if you want to check it out: <br>http://www.instructables.com/group/CoinOperated/
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 &quot;stop&quot; 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.<br>me quedo una duda respecto al servo.... <br>1)es necesario uno tan robusto? <br>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?<br><br>gracias!<br>Abrazo desde ARGENTINA<br>Jonathan
i didn't really understand it what do you use to make the coins come out do you think you can make a video/<br><br>
Encara, va un +1 gato.
you have a mole on your finger <br>
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
Hey congrats on winning the Grand Prize on Game.Life! I can't wait to build this over the summer as well!
awesome!!great job, love it!
I don't know why the text of two steps was disappeared.<br>I have already fixed it.
awesome!!great job
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. <br>I have a few questions about your circuit:<br>1) What do you mean by a 10K preset? Is that a 10K pot? <br>2) What might be some substitutes for a tip41c transistor? Is there another NPN type transistor that I can use?
1- yes<br> 2- there are several transistor that you can use, ask what they have in the store where you buy them.<br> Regards, Bruno.
i think preset is not a pot its a kind of pot which cannot be adjusted
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?
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.
TIP31 may work.
Hey! Acabo de pensar una combinaci&oacute;n genial. Tu caja y muchas monedas de chocolate (no se si soportar&iacute;an los golpes) pero estar&iacute;a bueno probar. <br><br>I had a great idea, I think, your box + chocolate coins = a winner.
Are those argentinian coins? ;-)<br><br>I like this proyect. At first I saw it in Taringa.<br><br>How much have you spent on it? / Cuanto gastaste viejita? &lt;--- google translator <br><br>Saludos desde Quilme'sh.
<br>A most excellent ible, shows imaginative detail work. I would think this would sell in the USA.
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 sta&ntilde;o ?
Si, uno comun de 30w tipo lapiz, igual hay que tener mucho cuidado. Saludos
i really think this one should win!
Groso taringuero!!
This <br>Is<br>Amazing<br><br>How much would you charge to build one for me?
you like super mario
how can i do this without the coin shooter i only like the noise please answer
Use any mp3 player and make the amplifier board.<br> Regards, Bruno.<br>
Una pregunta, con qu&eacute; comandas el servo? Porque los que conozco funcionan por PWM.<br>Gracias y buena idea!
