They need modification I got a couple of these 6 position rotary switches from Ebay and fitted one to a Turnigy 9XR Pro transmitter replacing one of the analog pots. The solder pads are labelled VCC, GND and FLAP, I assumed for +5V, GND and SIgnal. The result was a […]
Background Linux is the stuff going on in the background, the various flavours are what you see on the screen and how it works for you. The variations are referred to as Distros. I have been using Linux for everyday desktop machines for 10+ years. From memory, Red Hat briefly, […]
According to the Specifications The Power Unit is a dual voltage regulator intended for use in larger scale RC with bigger servos and greater power requirements. The higher current ( 8-Amp ) servo output can be jumper selected between 6.2V and 6.7V. The lower current ( 5-Amp) receiver-controller output is […]
These are just a few notes and comments created along the way. I hope they will help others. If you have any comments or additional information, please let me know and I will update here. NOTE: I don’t use Windows. It is supposed to be possible to update these transmitters […]
Power Supply Failure For no apparent reason the main voltage regulator burnt up while operating from a 3-cell Lipo battery (about 12V). It may be that if the supply voltage drops low enough, the switch-mode regulator can’t cope and self destructs. It looks like the failed switch-mode regulator drops the […]
With the hot summer days I decided to have a look at improving my fridge temperature controller. A couple of timing adjustments will probably improve it and reduce icing. Making a mini test fridge Not wanting to experiment on the working fridge, I built a small cold-box from foam PVC […]
We have just added a simplified low-cost receiver. This works as well as the other receivers but with fewer additional features and at a lower cost. See the product item: HERE See the tracker receiver support page: HERE
Experimenting with Solar PV Prompted by a telemarketing call I talked to the sales rep and updated some notes on home solar power systems. What they were offering seemed reasonable, maybe very slightly higher than you could find by shopping around, but they offered a 40 month payment plan. For […]
