we are controlling the ringing of an old phone with our computer

Agota and I finally made it!

In fact, it is not very difficult, but you need a big amplifier. You can check how to to this here: https://www.youtube.com/watch?v=0ma3mP35Ch0&t=118s&ab_channel=I%27manIdiot As we didn't have such an amplifier, it wasn't that straight forward specially because of the power supply. When we were using a 12v one, the little amp we bought in tiny tronics wouldn't have enough power for the phone, and the phone was only kind of 'vibrating'. It was funny but also a bit frustrating.

Then we adventured into the unknown buying a 24v power supply and fearing we may burn our amp... but the phone rang. What a moment!

Our phone is pretty important in Noise under the Umbrella, if you haven't seen it, you should try to come to the next time we play it!
