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 was announced several months ago (March 2021) to allow our members ample 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.

Help in activating sound system using R/C


Recommended Posts

I use r/c to operate my model trains. The whistle and bell sounds are normally activated by a controller with 2 tact switches, one for each sound. The controller is wired between the DC variable voltage power pack and locomotive sound module and motor. I'm looking for an r/c interface which will allow me to use my channel 3 throttle stick forward or back for a whistle or bell sound.

The power for the engine is routed through the controller. Pressing one or the other tact switch apparently sends a signal to the sound module to activate the sound. Each tact switch is a normally off SPST switch. I would like to find an interface(s) that substitutes for the tact switches that lets me use my transmitter toggle to activate the sounds. I've heard of R/C bit switches and believe Pololu may offer these, but need help in finding the right interface. Your comments are welcome.
