RTK Rover and Base Configuration Web Interface

RTK Rover and Base Configuration Web Interface
So I've been working on this for the past few weeks When I first started to mess around with RTKLIB I've wanted to have a nice UI to do that, while researching it I came across a product from drotek.com which already has a nice UI and I was glad to find its an open source (!!). So I decided to sit down and take a look at it, at first I was a little dissapointed to see it worked on Intel Edison Only as I didn't find this board particularly interesting and now...

Emulating COM Ports on Windows

Emulating COM Ports on Windows

The answer lies in the way power banks work and some of the power converters, as well as usb power supplies. In the good old days when you wanted to take a power source like 220v or 110v and down convert it to 5v, you would use a transformer, then a rectifier and lastly filter out the noise with a capacitor and...

OpenSprinkler using ESP8266

OpenSprinkler using ESP8266
"If necessity is the mother of invention, then laziness is the father." - attributed to Allen Dale Sometime ago I've read about OpenSprinkler (source code) and I had to try it, I was a bit dissapointed when first I saw it worked on Raspberry PI Zero, but then I saw other boards it might work on, until I've found a port to ESP8266 and decided to give it a go, but I should also note there's an official ESP8266 OpenSprinkler with Source Code. The design I chose to start with is pretty primitive, I didn't want any LCD or RTC,...
