Product added here. This is a in-line PPM buffer or level converter. It normally connects between the RC receiver and whatever it’s controlling, servo, auto-pilot, LED controller etc. Many modern receivers operate at lower voltages and output PPM signals of 3V or less. Sometimes this low level PPM signal must […]
I have added the high power strobe as a product. Link to product. Slightly smaller than a standard SD card . The strobe can be fitted to a RC model for visual effect or to make it more visible Designed originally for RC gliders that can be difficult to see […]
I decided to fit a OpenLRS module inside the radio rather than use the module. Using a receiver as a transmitter was one option, but I decided to strip the module and clean up and install the PCB. Read more here. All together about 4 hours work. Most of that […]
What’s with these Multirotors? So it’s now the end of 2013. Over the last 2 years Quad, Hex and Octo Multirotor flying as part of the RC hobby has become very popular and is growing fast. The parts needed to build a multirotor are now cheap and easy to get […]
I think I’m going to have to pull finger and look at building a simple RTL controller for RC model planes. This post is a series of notes just to put it all in one place and provide some food for thought. Comments or questions are welcome. So what is […]
Corona CT8J Module I’m using a Turnigy 9X transmitter with ER9X firmware and a few different transmitter modules including this Corona DSSS 2.4G. I recently had a few control problems with the Corona DSSS system and finally noticed that tapping the module could make or break the RC link. […]
A 40MHz control problem recently got me thinking again about lower frequency vs 2.4GHz control. I’m still using 35MHz as are a few others locally, as well as 40MHz and 72MHz. Local Testing I live about 2KM from the flying field so I can listen or test for radio activity […]
I have recently updated the RC LED flasher controller to simplify the flash pattern programming slightly. Originally you needed a LED connected to channel 6 to indicate the pattern count. The small on-board status LED now provides the indication as well as channel 6; which is still useful when the […]
