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.

  1. Last month (Feb 2019) I purchased a refurbished MP Select Mini V1 3D Printer for $89 USD (with free shipping). The flash price quickly ended, sold out. After the unboxing I found that mine was new (not refurbished). But I had to replace the extruder's cooling fan because it was too noisy. Monoprice did not respond to my email request for a replacement part. Fortunately I had a 12VDC 30mm fan that fit, so problem solved. I quickly discovered that WiFi connections were unreliable. For the record, it works fine when the printer is close to the router in my living room closet. But I need to print elsewhere. And the short range is understandable because the WiFi antenna is inside the printer, surrounded by the heavy sheet metal case. The solution is to convert the printer to use an external antenna. Before I talk about my antenna hack, I would like to point out that there is a fantastic wiki site that discusses a variety of mods for this printer. It includes instructions on how to enable WiFi connectivity, which is a hidden (unadvertised) feature of the V1 printer. I recommend that all MP Select Mini owners bookmark the Wiki: https://www.mpselectmini.com/start With all the formalities out of the way it's time to talk about the Wi-Fi antenna modification. Let's start with some fine print. It's not a hack for the typical mortal. Things to consider: It voids the warranty. Blame only yourself if things don't go as planned. Altering RF circuitry is not like working on a traditional DC circuit. In the RF domain *everything* matters. Good SMD soldering tools and PCB rework experience is a prerequisite. This hack is difficult/risky so proceed with caution. You've been warned. Before you start the modification, first confirm that your printer's WiFi is working. I shouldn't need to say this since the mod is for users that are unhappy with the RF range they are currently getting. But some hackers like to do mods just for the sport of it, so that's the reason for advising to fully test it out before any hacking.
  2. Hi there, I recently bought a 2.4GHz booster (amplifier) for my Flysky FS-T6 which has one antenna. Looking now at the newer Flysky transmitters like the Flysky FS-T6 & Flysky FS-T6S I notice they have two antennas. Will a single booster work with a dual antenna transmitter? Can I attach it to just one antenna, leaving the other un-amplified? Booster (amplifier) link: http://www.ebay.ca/itm/321483168025?_trksid=p2060353.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT If not, will this also work as a second booster? http://www.ebay.ca/itm/20MHz-2-4GHz-Low-Noise-RF-Receiver-Amplifier-Signal-Amplifier-VHF-UHF-H5-010-/162144831545?hash=item25c095c839:g:dwMAAOSw0fhXkin3 Thanks very much in advance
  3. Hello, I'm new here, so 'hello' I'm not an R/C person, but I may have a use for an an el cheapo 27MHz set-up. I want to make a link, over only about 50 feet, but it has to be wireless. I have considered an optical link, but at the moment I'm still at the stage where questions are being asked. I will attempt to make this as coherent as I can: The receiver is not a normal R/C receiver; it's a quite different electronic device which I need to turn ON on demand ( so a timer /PIC is not much help here ). The device has to be battery-powered and the battery will be (hopefully ) kept charged by a small solar panel. Ergo , I need a method of turning this device ON using some kind of receiver which draws little, or no, current. Now, there is the unpowered field-strength meter, which can generate a few hundred milli-volts when close to the transmitter. I have a home-made transmitter which is around 100mW AFAIK ( it's very old and uses a design of Mike Newell circa 1970 : anyone old enough to remember him?) So, using this transmitter, I want to send a signal to a tuned-circuit 50 feet away. Can I get enough response from an unpowered tuned circuit to 'trip' a second circuit ( which will be battery-powered ) into life? The first circuit could conceivably be powered if it draws only micro-amps. Does anyone know if this trick has been done before ( I've not seen anything on Google ). Or can you make suggestions as to how it could be accomplished. Regards Bruce
