1  Topics / Device Hacking / Arduino As USB Host? on: November 21, 2012, 10:49:15 am
I recently upgraded my computer's tower case and wanted to use the old USB ports from the old case with the Arduino.  There are 4 wires per port: +, -, D+, D-.  How could I get the Arduino to act as a USB Host to drive a keyboard?
2  Topics / Device Hacking / Hacking Credit Card Terminal? on: April 27, 2012, 09:38:53 pm
Anyone have any experience hacking any Verifone Terminal in general? I have couple of these and really want the display, keypad, and mag stripe reader. Any ideas?

Most do have a RS232 and Telco ports. Is there a way to interface there?

I would like this as well. I have found a thread on another site:, discussing interfacing with an Ademco/Honeywell Keypad (Looks the same for DSC too), and they found the interface uses 4800 bps Serial. Anyone have an idea on how to do this with an Arduino?
