This is a post to highlight all the changes and testing that has gone into the new design Wind Sensor Interface. I developed this sensor board to monitor different wind speed sensors (anemometers) and wind direction sensors (vanes). The main problem was that the wind speed changes rapidly and so any data-logging system needs to be powered up and recoding... Read more

These kind of lights are readily available, but they usually contain a nickel-metal-hydride (Ni-MH) battery (usually a 1.2V AAA sized cell). I have seen a lot of these lights which... Read more

My houseplants have been dying due to a mixture of over and under watering. So I thought something to help stop that would be good. And even better if it's solar powered. I've been working with a solar powered ATTiny85 for the Solar 8 Ball and Solar Dice kits and thought I could use the same basic circuit to implement... Read more

I have built an environmental monitoring unit for my workshop. This measures: Air Temperature, Humidity & Pressure PM2.5 and PM10 Particulate values Radiation levels It shows the data on a small OLED screen. There is a large LED RGB display which changes colour if data goes above warning levels. This unit sends data to AdafruitIO via MQTT messages. This is all... Read more
