Wow, it’s been a while since I posted. Things at work were crazy the past few weeks and now family is in town for turkey-day. Today I got a chance to sit down and catch up on my news and sites.

First things first, Mike S is the winner of the October Tip contest and I shipped off the Olimex PIC-MT from Sparkfun Electronics at the beginning of November. Congratulations Mike, we hope you can use the board. Send us some cool projects!

Sunday Hack-a-day.com posted a project on a Morse code interface for a PC and it got me thinking. I’ve always thought Morse code was cool and after reading about the project I started browsing around looking for cool projects.

In my surfing I came across this Morse code to ASCII decoder circuit using a NE567 Tone Decoder, PIC16F84 and alphanumeric LCD to translate tones into characters.

The project has a good write up on how the device works and it lists the complete source code written in PIC ASM, not bad for a 9 year old project.

Great link! I am studying for my ham license and I will definitely be building this next month when I pass the test! Now I just need to find a distributor that sells the NE567 IC.
