 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

Here is something to consider - and something for me to show off. I've added an internal speaker to my setup, using a LM386 power amplifier. The project I adapted is this one here: http://hackaweek.com/hacks/?p=131 I went with this because I didn't want to bother with the headphones, I just wanted my box to make noises... and, well, building stuff is fun really. Here's it in action. The speaker I got from Altronics, the smallest one they had. The IC is quite amazing. In, out, and just a few caps. Runs at about half a watt. Mine's plugged into a 9 volt battery at the moment, but it could run off the computer's 5 volt rail, I plan to fix that up later. |

Nice, I like the idea of the CMM being able to give basic sound without requiring anything else (headphones or external speakers, etc). Cheers, Shane |
