rfpp53 datasheet
I looking for a data sheet for an RFPP53 RF power mosfet. I believe it was made by Philips. I've searched the net with no luck - any help would be apprciated.
Thanks
You could take a look at the manual for a commercial device - The Polhemus Fastrack manual has a reasonable theory of operation section. Look here hxxp://www.polhemus.com/support.htm.
You could also try doing a patent search at www.uspto.gov. Many patents contain simplified schematics.
If 7 segment displays will work for you, Orient Display has a large 100mmx60mm standard single digit panel.

I have made some great looking panels by inkjet printing on good quality paper and then laminating in an adhesive backed lamination pouch. Check out the lamination supplies at your local office supply store.
I suggest you visit ti.com, analog.com, linear.com etc. and do a search on ECG and EKG ( electrocardiogram ). Many of these semiconductor vendors have app. notes for simple ECG amplifiers and heart rate determination.

simulating blood flow
Ironjaycuttler, you can use whole milk to simulate blood for doppler ultrasound measurements. The fat globules in the milk reflect the ultrasound.
photodiodes amplifiers
Check out http://www.taosinc.com they have some integrated photodiode/amp sensors that I have used successfully in some designs.
