GruePhone Lives Again!

Wow, it really has been a while, but improvements in technology have given me an idea of how to improve upon the original Dial-a-Grue phone. The idea is to use a small embedded computer, this time a $9 “chip” computer and actually embed it into a gutted phone.  From there I can use text-to-speech (tts) and […]

It’s Alive!!!

What I hope will be the final piece of the puzzle arrived today.  It’s a little adapter that turns a regular modem into an acoustically-coupled modem.  It’s intended for use when there isn’t a regular phone line available—you can strap this to a regular handset instead. I decided to do a proof on concept, just […]

Brains too small, make bigger…

I supposed I should have figured this out earlier, but there just isn’t enough SRAM for the zip interpreter to run the Zork I story file.   It is trying to malloc() approximately 30KB of ram for various data structures, and the poor little Arduino Mega only has 8.   It might be possible to […]

Ears and Mouth have arrived…

The key to making this project work is allowing it to communicate with the old TDD.  To do that, I’ve managed to acquire a couple of TDD modems, specifically designed to talk to TDDs.   The Intellimodem can even do Baudot, which the TDD does (at 45.5 baud[*]). More after the break

Grue Brains — the plans

Since my original concept was to power this with an Arduino microcontroller platform, I’ve decided to see if I can power it with an Arduino Pro from Sparkfun. Why Arduino? Why not code to the bare uC?  Arduino has got a nice IDE, which makes development easier, and it’s got lots of pluggable hardware that […]
