So, Phil was dorking around at Splat*Space, indulging a nostalgia kick for the “old skool” phone phreaking days. To that end, he created a simple simulated phone circuit (hint: just wire two phones together with about 12 volts on the line… you can’t ring the phones this way, but if you take both off-hook, you can talk back and forth) and then had an Arduino board generate a 2600hz tone, which was then piped into an op-amp and then injected onto the phone circuit. As you can see (and hear) in the video, bridging from the Arduino world to the POTS world works quite nicely.

Also in this album are a bunch of pictures of the space. If you’ve ever wondered what SplatSpace looks like, take a gander.
