Arduino to Mitutoyo Interface

We have produced a few more Mitutoyo to Arduino interface boards. This is a simplified version for a variety of micrometer and caliper to computer applications, from datalogging to CNC or milling machine control. Get the full code and schematics, or discuss the project. The 6 pin header is wired left to right as:

5 is /Request
4 is the button on the cable
3 is Clock
2 is Data
+ is +5vdc
- is Gnd

Text to Speech

We have been playing with text to speech again. We used a Sparkfun voice box shield that includes the popular SpeakJet chip. The issue is that you have to code "phonetic" allophones to tell it what to say. It won't read the contents of a normal variable and convert it to recognizable speech. So we added a TTS256 chip, which takes English text and numbers from variables, and builds the correct allophones for the SpeakJet.
