ATM Progress

All photos. More photos.

So making great progress with the disassembly. I took all the decals off:

Here is the receipt printer:

The CPU is inside the vault:

The CPU:

Startup screen:

The cash dispenser:

I got a $20 stuck in the dispenser:

Loaded it with some cash. This ATM can hold $50,000!


The plan is to directly interface with the stepper motors of the dispenser and the ATM screen.

So a small linux computer will control an Arduino which will control a stepper motor controller.

Bitcoin ATM

All photos.

So I’ve decided what I’m going to do with bitcoin. I’m going to build a bitcoin ATM.

I bought a used ATM on ebay. This will be fun….


Possible Directions

What shall I do with Bitcoin first?

To date I’ve downloaded the mac client and purchased some bitcoin. My next step is to get bitcoind compiled for my macbook.

Some services I could build for Bitcoin:

  1. Bitcoin futures market
  2. Bitcoin credit
  3. Bitcoin credit scoring
  4. Bitcoin escrow accounts
  5. Bitcoin fundraiser using pooled mining

New Beginning


For over a year now I’ve been imagining a peer to peer currency. I imagined it as a git for money.

Last month I discovered that this peer to peer currency now exists; its name is Bitcoin.

A brief summary from wikipedia:

Bitcoin is a digital currency created in 2009 by Satoshi Nakamoto. The name also refers to the open source software designed in order to use it. Bitcoins, abbreviated BTC, can be saved on a personal computer in the form of a wallet file or, kept with a third party wallet service, and in either case, can be sent to another person over the Internet to anyone with a Bitcoin address.

Unlike most currencies, the bitcoin does not rely on trusting any central issuer. Bitcoin uses a distributed database spread across nodes of a peer-to-peer network to journal transactions, and uses cryptography in order to provide basic security functions, such as ensuring that bitcoins can only be spent by the person who owns them, and never more than once.

Bitcoin’s peer-to-peer topology and lack of central administration make it infeasible for any governmental authority, or anyone else for that matter, to manipulate the value of bitcoins or induce inflation by producing more of them. Bitcoin’s design allows for anonymous ownership and transfers of value

This blog will follow my exploration of Bitcoin, and my exploits building tools for the Bitcoin ecosystem.

My name is Mark Suppes. Previous credits include building an open source nuclear fusion reactor.
