Brian Lough wanted to put his own stamp on his wedding. He admits his wife did most of the actual planning of the day, but Brian brought some electronics and wifi magic to the table centre decorations, pictured in action above. He used Ikea Grono lamps as the main structure of each lamp and then added a Wemos D1 mini and a Neopixel ring for illumination. Each lamp was powered by two 1200maH battery banks bought from Poundland. The Wemos boards are sent commands from a Raspberry Pi Zero via a cheap wifi router which connected everything together. The programming on the Pi was done with NodeRED. You can read how to do it yourself over on Instructables and you can also see how it all works in the video below:
