Strange Microchip PIC behaviour

A 10  minute change that has taken 3 days I needed to change a time delay in a 8-pin PIC12F675 project started 4 years ago but has been updated since.  No problem I thought, change the time, recompile, save a new output file and program some chips. But the chips […]

Mouser Order Delayed

Conclusion – Resolved Keep enough stock on hand – but how much is enough.  Don’t rely on suppliers to come through if you are caught short. Mouser did resolve the issue and release the order. But we will have a 4-5 day gap in production. Not Always Quicker Being a […]

FPV Tracker on 2S Lipo – a question from Dave

Question: I just wanted to know the operating voltage for the FPV RC BEACON, when its signal lead is connected to a RC receiver running directly on a 2S Lipo, which can reach 8.4V when freshly charged. Maybe a glider install. Answer: The FPV tracker does monitor the power and […]


Orange Pi Lite and Zero boards

I have a couple of applications in mind and thought these boards looked quite interesting.  Small, low cost reasonably powerful.  So I bought two each of the Orange Pi Lite and Orange Pi Zero boards, and a couple of camera modules. The first application is a weather station, which is […]

6 Position Rotary Switch – flight modes

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 […]


Linux Update – Aug-2016

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, […]
