So the design I have prototyped would be specific to the Arduino. Opto-isolating the input pins makes it much more robust for security/access control applications (especially since most of the readers are powered by +12VDC and the Arduino can only handle 5V) and the relay outputs can be used to control a variety of hardware. I'm thinking this could be used to log attendance, do access control to various zones, run an honor-system or hardware enabled vending system, lock out machines from unauthorized use, control who can open your server rack, etc.<br>
<br>Will see about getting some boards made. I'm thinking a bare-board would be easiest to produce, as the components are all pretty garden-variety.<br><br>Arclight<br><br><div class="gmail_quote">On Mon, Feb 8, 2010 at 2:12 PM, Elmo <span dir="ltr"><<a href="mailto:elmo.mantynen@iki.fi">elmo.mantynen@iki.fi</a>></span> wrote:<br>

Crowd funded generally useful openhardware for hackerspaces distributed at near cost? How common is that particular model? Could it be made to usable with other hardware also?<br>

Speaking of which, is there any interest in an Arduino shield board that provides opto-isolated inputs for the Wiegand26 readers and keypads, and 10A relay outputs?<br>
<br>
This would be good for access controls, refrigerator accounting at the space, etc.<br>
