Altimeter

Recommended Posts

Hi,

I've build an altimeter based on this schema (I did not include the 7805 nor the lcd)

http://geocities.com/SiliconValley/Orchard...ltimetersch.jpg . It works ok on the ground but once I used it on a plane (plugged on a spare channel) I have a lot a noise on the graphic. How can I avoid this ? Is there any technic ? Or maybe should I run ir from a battery ?

The MAX ADC and Motorola sensor require clean 5.0VDC +/-5%. I wouldn't expect that from the typical R/C system power buss (power is very dirty, even when a BEC is involved, due to servo activity). It's hard to say if this is the main contributor, so other issues may be involved.
