Attention: RC-CAM.com will be closing down August 2021.

The RC-Cam.com forum was the very first online community dedicated to the advancement of wireless video cameras on radio controlled (R/C) models. This is now called "FPV" (First Person View). We are proud of the contributions that our members have made to the FPV hobby.

We've seen significant changes over the last twenty years. Initially there were a lot of eager R/C hobbyist that built their own video systems. Allowing these creative individuals to share their work was the purpose of this site. Now the FPV market is flooded with low cost systems; Sadly DiY FPV video projects are now rarely discussed.

RC-CAM.com (main site and forum) will be closing down August 2021. This is being announced now (March 2021) so that everyone has time to download any information that is important to them. After the site is shutdown the information will no longer be available here.

We appreciate every member's involvement with advancing the FPV hobby. It is indeed sad to say goodbye to all our online friends. Be safe and stay healthy.

I'm looking for a stand-alone LVC circuit.

Sometimes I need to test or evaluate batteries by discharging through a resistive load at X-Amps and it would be very useful to have an adjustable LVC so I could run the battery down to the safe cutoff without having to watchdog it.

Any ideas or pointers for an LVC?

Yes, very easy to do. I built some a few years back for my r/c racing car club guys. I used an LM393N voltage comparitor chip and a zener diode as the voltage referance. The circit was powered by the batt being discharged and a relay released at the preset voltage disconecting the whole thing.
