  • Fun and clever hack

    From 3 comments
    • Ha I love it! I love seeing old hardware hacked to bring it kicking and screaming into the modern world. This is why I love things like Arduino's. They a cheap but so much fun.…

    • I did one about 10years ago using an old phone I got at a garage sale. I was going to copy the Sparkfun design but instead I made mine a Bluetooth one so that you don't have to…

    • I love this project. The great thing about it, unlike many technically impressive projects, is that it's only going to get more and more fun to take this out as time goes on. If…

  • Nice write-up and build

    From 2 comments
    • A classy product and an even classier write-up! "Having solved two problems with one excuse,..." I trust I am free to also use this phrase? Beautiful!

Objections

  • Similar projects already exist (Sparkfun kit)

    • Unfortunately not even a shoutout to the nearly-identical Sparkfun project from over 10 years ago... https://www.sparkfun.com/tutorials/51

    • As others have pointed out, this has been done many times before. There's even a commercial product to pair an analog phone to a Bluetooth cell phone.[1] It generates proper ring…

    • I'm afraid this project has been done many times by many people. SparkFun has even made a (now retired) kit. https://www.sparkfun.com/products/retired/287…

  • Pricing time cost takes fun out

    From 1 comment
    • A tiny bit of criticism. “The entire build cost something like $150 in parts and $2000 in development time.” I think adding a price to a personal project takes part of the fun…

Requests

  • Commercial sale or Kickstarter

    From 3 comments
    • Go for the Kickstarter! :D

    • Hi, I love your phone :) I'd also love to have one. My friend here in Prague I think would be able to help with the design in order to keep the bell - it MUST be possible. Also a…

    • This is crazy! You could sell these, I'm sure there's a market for them. Great hack!

Questions

  • Can the original ringer be used?

    From 2 comments
    • Really fun project and great end result, although sucks you couldn't make use of the original bell. I recently bought an AT&T Traditional 100 touch tone phone with a similar…

    • This phone also has a two-state button, which I made into "force dial" (when you've already dialed some numbers) or "redial" if you haven't dialed anything. Someone did actually…
