Raspberry Pi

An inexpensive computing solution for MPL’s OPAC

What’s a Raspberry Pi?

Why Pi?

• A general purpose desktop ranges in price from $300-$600.

• OPACs are only needed to browse the library’s catalog – a lot of the features on a GP desktop are unnecessary.

• Raspberry Pis (RPs) have a base cost of approximately $39, and can be outfitted with cables and case for under $100.

When smaller projectors get upgraded, we will have 2 VGA/HDMI adapters

Location

We could ask Dominic to build us a shelf to secure the RP and cords.

ADA accessible OPAC –currently only really have in YSD.

Locking them Down?

• RPs have a built-in kiosk mode that can be turned on. They can be set up to go right into a full-screen browser.

• Create a user login so that patrons can’t access the root login.

• Physically secure RP using whatever apparatus we use to house the user peripherals - make an “outer case” to secure board and cords, while still making it accessible for staff to do troubleshooting.

But Linux! Code! Ahh!

• The Raspberry Pi Foundation, who makes RP, is all about Education.

• The original intention was to make a small, affordable computer so kids could learn how to code.

• This means there are tons of articles, blog posts, and forums on how to set up and troubleshoot your Pi.

What About Staff Time?

• We should be able to get a RP set up and configured in about 4-8 hours.

• This translates to $69.44-$138.88 worth of staff time (VS Librarian).

• This is still cheaper than having our IT perform the set-up.

IT Support?

• Ed is familiar with RP (he has two of them himself) so would be able to help troubleshoot if needed.

• RPs is run on Linux, so anyone with an understanding of Linux should be able to do tech support.

What Else Could We Do?

• Set up a retro gaming station for kids/teens/adults.

• Digital Signage

• Include a RP in a mini maker-space.

• Programs (run by http://workshop88.com/ -they did one for St. Charles)

Summary

• Adding additional endcap OPAC stations would be more financially reasonable with RPs, at roughly $100 per computer.

• Would be “just enough” computer to serve the necessary purpose.

• Plenty of “how to” out there to help us along in getting set-up.

• Potentially for expanding to replace the plasma screen computer.
