We love payphones for obvious reasons and seeing them alive and kicking warms our hearts. Packing them with local history checks even more boxes. Twenty-four people collaborated to rebuild the three phones which can be seen in the video after the break, including three visual artists, three ambassadors, and eighteen residents who put their efforts into making the phones relevant not only to the ward but specifically to the neighborhood.
One phone plays sound clips from musicians who lived or still live in the ward, another phone has spoken word stories, and the third has field recordings from significant locations in The Tre.
Each phone is powered by a solar cell and a USB battery pack connected to a Teensy with an audio adapter board, and a 20 watt amplifier. Buttons play back recorded messages exclusive to each phone, star will record a message, and zero will play back the user-recorded message.
Apps for smart phones are easy for young folks to figure out but the payphones ensure that these time capsules can be appreciated by people of any age, regardless of how tech savvy they are and that is wise as well as attractive.
The coin return lever and coin slot also have associated sound clips unlike regular payphones so the artists get extra credit. Did we say that we love payphones? Yes, yes we did. The very first post on Hackday was for a redbox and that got the ball rolling. While seldom seen out in the wild these days, they can however still be acquired for a moderate fee — how many of you knew that? Conspicuously mounted in the corner of his office, a rangefinder sets the phone to ringing when somebody walks by — a fantastic trap for luring the curious into a nostalgia trip.
For this gathering he had enough time to put a Linux computer inside the old payphone. But with the Adafruit 20W amplifier and speaker. That's loud. If you just want to play the ringing sound of the bell, a simple 3W speaker hooked up to one of your output channels will be good enough. Here is a great step-by-step tutorial for the amplifier by Adafruit. I degraded all the sound files to kbps and ensured there was clipping in all of them.
I really wanted to stay true to the era. If you have any tips to make the sound HIFI, please share them in the comments.
As I mentioned earlier, the phones is extremely heavy. The bracket is imperative. I was able to mount to drywall thanks to the bracket. Question 3 years ago. I'm currently looking at the payphone.
Do you think they removed the main components you mention in your instructable or do you think they take more? If they only got the main parts, this seems to be a better solution for those looking to start this as a project. What do you do with the Laser Cutter.
Question 3 years ago on Introduction. Would anyone be willing to direct me to instruction on a much simpler concept for me? Looking to rig a payphone so it plays music through the handset when you pick up the receiver. No need to integrate the keypad or the change return. The plan was to hide a small iPod in the change box and connect the audio to the receiver, then power the project with a solar cell mounted to the back of the booth.
Has anyone done anything like this? Reply 4 years ago. The code is so easy to modify honestly. It looked daunting at first to me, but the more you look at it, the more you understand what to change and how. I think my favorite part of this whole thing is the comment at the veeeery bottom of the code about null termination. Fuzzy, how are you connecting power to your amplifier? I've looked through all the photos and cannot see any power connections. Any guidance? I apologize, I think I phrased my question incorrectly.
Both the amp and the Mega need power, so I'm curious if there's two power supplies needed, or if one piece is pulling power from the other piece. Thank you for your reply! The phone was free and the Arduino was free so quite cheap for me. I am newer electronics but I thought I'd try to "hack" using an old payphone I had. When I opened the keypad and used my multimeter against the circuit board, I could not get a reading on a continuity test.
It's probably just me not knowing what I am doing. The keypad on my Western Electronics looks a little newer than the phone you hacked. I am unsure on where to go to next. Would you be able to take a look at these pics and point me in the right direction? Reply 5 years ago. I read through the tutorial and followed the steps. I did remove the extra board, but connected and took a picture of it to show that in addition to the phone.
If you can't get it to work just call payphone. Your phone guts look super modern compared to the ones I opened up. Thanks for the direction. I worked on it this weekend and now have the keypad working. I also started on the other steps and will post when finished. Thanks again!
Congratulations Fuzzy, inspired project that truly deserves winning the 'grand prize'. I would have voted for it if I wasn't also a competitor! Introduction: '90s Payphone Boombox Hack. By Fuzzy-Wobble Follow. More by the author:.
About: fuzzywobble. A payphone is expensive. A payphone is hard to get. And the hack, surprisingly, turned out to be quite elegant : With my payphone hack I created a the 90 From The 90's Boombox : With this Instructable you will learn how to control the keypad, switches, and audio both in and out on a payphone. So it is possible there are even cheaper options out there. Payphone mounting bracket.
Remember these phone are cast iron, thus insanely heavy! I would NOT recommend trying to mount them without the bracket. Adafruit MP3 Maker Shield. Arduino Mega. Adafruit 20W Amplifier. Adafruit sells this one. Use this if you just want ringing but no music.
Typical stuff: wire, headers, tape, soldering iron, etc. CODE see attachment. There are 4 things to remove: The coin machine. Use the release at the top. The main CPU. Use the giant flathead screw. The weird grey thing. Just pull on it. The wild screw terminal thing.
