How is this for a medical instrument.....

Good progress with the Propeller>MRL linking.... just routing single elements at the moment... just to open up the gate ways..

Left to Right ..... 3 analog pots.....then  Pulse board ... notice originaly it uses a peg to house the IR led and detector ...so you clipped your finger and a beam of IR when through your finger......I later found out that the detector and IR led can be facing both forwards and side by side ...place finger over the two or toe or ear and it acts as a reflective detector... even 1 cm away from the pulse you are measuring..... its based off a LM324N opamp chip...

...continue..... the Yellow egg thing is my temporary ADC chip holder ( i made quite a few modules in this format as it helps me to develop global projects using "Off My Shelf" bits.

To the Far right is the Easy Prop board... the one i use mostly for development as it has SD card and XBee socket composite video and a PC screen output to.....

thats the basic system...
