Possible ESP8266 Fake or New Pinout?

After the first run of Ebulobo boards I’ve been assembling the parts to make some more nodes. I’ve updated the PCBs making sure that there is a ground plane and put some labels on the pinout. Like last time I ordered 10 RFM69HW radio modules and 10 ESP8266 modules from China via Alibaba. As always […]

Solar/Capacitor UKHASnet Node

Introduction There are a number of ways of powering UKHASnet nodes, indoor nodes suit having a permanent supply such as power from a usb port or a wall wart/socket but for outdoor nodes you usually need a power source such as a battery or solar powered. Solar power is both an awesome power source as its […]

UKHASnet Antennas 1

Introduction Antennas in regards to UKHASnet is an area that is under explored. I have used a number of different types both homemade and commercial and am yet to find something that works well. Many nodes have a single wire antenna cut to a 1/4 wavelength (82mm) – often just put in place for testing […]

Working with Supercapacitors

I’ve always been interested in using supercapacitors for powering UKHASnet nodes, its something about the simplicity of how you can use them. As I’ve been rebuilding my network I’ve wanted to put a solar powered repeater on the roof to add some range and so thought this would be an ideal opportunity to use supercapacitors. […]

Setting up a UKHASnet Network

After moving house at the beginning of September have finally got round to rebuilding my UKHASnet network. Where I live now will hopefully be ideal as the house is 3 stories, with good views to the north towards the Kent North Downs. First step was to setup a gateway, for this I used the old AB node […]

UKHASnet Hack Weekend

Individual node descriptions to follow in future posts, pictures from Phil Crump and Dave Brooke After much discussion and very little planning a group of 10 people meet up in Southampton for a weekend of hacking UKHASnet nodes. The plan was to spend Saturday building, programming and setting up UKHASnet nodes and then on the Sunday […]

Developing a remote UKHASnet node

For the past 6 months I have been working on a prototype UKHASnet node which is completely powered by solar. The aim is to install a UKHASnet node on the Redsands Forts out in the Thames Esturary where it will function independently both providing simple sensor data but also acting as a long range repeater.
