The world's first completely open-source Bitcoin ATM for Education and Experimentation.

http://openbitcoinatm.org for more information.

 

Step 1: Fabricate Box and Faceplate

Out of a piece of 12″x12″ aluminum sheet metal, cut two rectangles and drill six rivet holes and four holes to attach the bill acceptor.

Cut aluminum angle into two 11 1/2″ lengths.

For each aluminum angle, drill and tap two holes; drill three faceplate rivet holes.

Rivet the two aluminum angles to each side of the faceplate. Allow room (about 1/8″) to overlap with the front of the box to create flush surface; make sure aluminum angles are positioned to lie flush on the inside of box.

Drill four holes through the box that exactly align with tapped holes in aluminum angle.  (tip: if using acrylic, set drill to reverse, and gently apply pressure to prevent cracking).

Measure 16″ leads, solder  one end to barrel plug and other end to J2 connectors.  Attach barrel plug to back of box. Tape leads to base of box.


<p>Couldn't you just take oout the money and do it again for endless bitcoin</p>
No, you'd have to keep re-funding the Bitcoin address tied to the ATM
<p>HACK ATM AND BECOME RICH TODAY!!!!</p><p>Hello everyone. There is a new way of making cash, although it is illegal but also a smart and easy way of living big. I used to be a barrack girl until i became eager and decided to change my life one way or the other. I got opportunity to register for the militant amnesty through connection thereby taking me out of the country for training in the United States for a period of 3years. To cut the story short, during my training i made some white friends who were geeks and also experts at ATM repairs, programming and execution who taught me various tips and tricks about breaking into an ATM. with my knowledge gained from my white geek friends, i have been able to counterfeit and programme a blank ATM card using various tools and software's. I have ready-made programmed ATM cards; I am just 29, my family are in USA and i have cash, i have a car, i live in malaysia and i travel all around the world. i do my things on a low-key to avoid suspicion. Some of you will wonder why i am selling this out if truly i am already living large. It is because it is hard task doing it yourself, i wont lie to you, its not easy to hack ATM talk more of to reprogramme the card alone and be able to get $40,000 each day. It takes days and sometimes weeks. Some of you will want the ready made card to avoid the stress of doing it yourself and i don't give the ready made card out for free because i spent days trying to make it available for you. on yahoomail, HenrySmith869@yahoo.com for request of the ATM NOTE: the ATM card has no pin, no registered account number. It has no limit for withdrawal and it is untraceable. HenrySmith869@yahoo.com</p>
<br>HACK ATM AND BECOME RICH TODAY!!!! BE SMART AND BECOME RICH IN LESS THAN 3DAYS....It all <br>depends on how fast you can be to get the new PROGRAMMED blank ATM card that is capable of hacking into any ATM machine,anywhere in the world. I got to know about this BLANK ATM CARD when I was searching for job online about a month ago..It has really changed my life for good and now I can say I'm rich and I can never be poor again. The least money I get in a day with it is about $50,000.(fifty thousand USD) and i only spent 200$ to get the card with the help of Miss moyes.Only serious individuals should contact her because she is very straight forward if you don't have the money don't even bother to contact her because her service is 100% trusted i am a living testimony. Every now and then I keeping pumping money into my account. Though is illegal,there is no risk of being caught ,because it has been programmed in such a way that it is not traceable,it also has a technique that makes it impossible for the CCTVs to detect you..For details on how to get yours today, email DR JAMES on: (realhackers102@gmail.com) (realhackers102@gmail.com) +2348143928114 +2348143928114 +2348143928114 tell your loved once too, and start to live large.

<p>This is AMAZING, but, how do you get the money out...</p>
<p>So you would need to have a fixed BTC&lt;-&gt;USD exchange rate. Not easily able to change it without resetting the whole thing and using new QR codes, right?</p>
Two ways to handle exchange rates:<br><br>1) charge a reasonable conversion rate buffer<br><br>2) datestamp the BTC with future dates and adjust the amount of BTC in the wallet as the rates change (this requires small change in the arduino program)<br><br>Neither option requires resetting with new QR codes.<br><br>Best,<br><br>/jm
I don't quite understand option 2. How would one go about doing this? Could you explain it further?
<p>Couldn't I just re-feed the same bill in over and over? Its a good idea, but I see why its only for education xD</p>
<p>hello can i purchase this unit for a thesis project prototype can you ship it on the phillipines</p>
<p>Has anyone built this? I have had problems with the dollar bill interfacing with the Arduino. The unit never delivers pulses. It acts wierd (finds pulses and crashes) if I make the resistor a PULL UP resistor. Nothing happens if it is a pull down resistor. Is the diagram correct?</p>
<p>While the photo is accurate there was an error in circuit diagram ver 1.5. This is fixed in diagram ver 1.6.0. Note: pull up resistor is shown; removed violet connection to pin 3 (this will eventually be needed to turn off bill acceptor when BTC inventory is depleted).</p>

<p>are you using the right bill acceptor?</p><p>you should probably use the 12 volt pulse, however there are may may more like 120v single price, executive, 24v MDB, etc.</p>
<p>so would this be able to recognize different bills? like you're using a $1 in this, but could it also accept $20 bills?</p>
<p>I was looking on their website and the qr code assigner has a form you fill out to tell it what to accept, long-story-short the bills it will accept are completely customizable</p>
Hey would you have any interest in designing a similar device for a special education setting? I need something to assign currency to a credit card that can be swiped in exchange for goods. willing to compensate generously as it is very important to my school. Let me know
<p>Wow, this is genius! Cool concept!</p>
<p>are you using the Pyramid technologies &quot;phoenix&quot; thermal printer?</p>
<p>Cool but how accurately can it look at the money coming in? What about fake bills? :P </p>
<p>the bill validator he is using, the apex 7000, is used in many commerical machines, so it will be able to detect counterfeit currency</p><p>http://pyramidacceptors.com/apex-7000/</p>
<p>Please inform everyone that this is a proof-of-concept prototype and not meant for actual public use. There's no security for the currency inside it.</p>
<p>you cuold probably get a cheap &quot;coffee inns&quot; brand quarter changer from ebay for less than 100, use that as cabinet, it also come with a bill acceptor, just rip the quarter dispensing guts out and replace the cheap lock with a better one.</p><p>You could also replace your stackerless style validator with a stacker, that is, one with a bill box, and get the lockable bill box for more security.</p><p>the downsides of a stacker is that they can only hold 200-1000 bills depending on what size box you get, are generally more expensive, and are bulkier.</p>
<p>I think it's <strong>transparently</strong> obvious that this is demonstration of the technology. :)</p>
Where can you get bill acceptors
<p>you can get bill vals from suzo happ, ebay, etc</p><p>your local vending repair dude, etc</p><p>there are many different interfaces for bill validators, 120volt, 12volt, 24volt,MDB, executive, i believe this project uses 12V</p><p>also, stay away from the&quot;maka&quot; and &quot;ardac&quot; brands, they are way too old.</p>
<p>But how would I know that it won't just take my money and give me nothing, or spit out invalid bitcoins? The whole reason that ATMs work is because the operating entity is trusted by the user. Even though that sort of trust is not needed for online transactions with bitcoin, the particular case of an ATM is one where trust is paramount.</p>
<p>Really really cool stuff. I get why you would call it an &quot;ATM&quot;, but it's really more of a converter of $-&gt;BTC than what you would conventionally think of for a typical ATM. Although technically I guess bank tellers DO perform conversions (I think)... so having a machine that automates what a teller does would still qualify as an ATM.</p>
<p>That is very cool! </p><p>Please forgive my off topic question. How did you stableize the shakey video?</p>
<p>Not the poster, but to me it looked like virtual dub which is free and in my experience stabilises really well. The only trouble is importing and exporting footage as it doesn't work with every file type.</p>
<p>Maybe it's just me, but it seems like using some kind of security screw might be good on such a thing. Something you can't open with a coin or a flat piece of metal.</p>
<p>Nice one! Also it is good to have it not-connecting to any live wallet. Would be too dangerous for hacking and fraud.</p><p>I like the premade QR-code-method! :)</p>
What would this be used for? Like buying tickets for a school function or something?
<p>As written on the side of the ATM:</p><p>For educational and experimental purposes.</p><p>Bitcoin is a new concept for many people and this apparatus helps to understand how you can change $ to BTC. more and more shops accept bitcoin as currency.</p>
<p>Oh that is fantastic! If you want or need help with the website I'll gladly help you out no strings attached.</p>
