We now have air quality (PM2.5 & PM10), temperature, humidity and pressure monitoring at the shed. There’s an SDS011 and a BME280 sensor connected to an ESP8266 upstairs in the corner near the printer. Readings are taken every 5 minutes and uploaded to an influxdb server which grafana is pulling it’s data from to produce these neat graphs available here:

The plan is to extend this and have outdoor monitoring as well as other interesting data points…

Jenny gave an interesting talk at the 2019 CCCamp in Germany asking for better standards of official investigation and media reporting into British drone incident stories.

Looking at the sorry saga of drone incident reports and drone-related airport closures in the UK, and shining a light on the woefully poor quality of official investigations, police response, and media reporting.
Over the last few years the UK has seen a public moral panic over reported air proximity incidents between…

Our very own Jenny List gave a really interesting talk at EMF Camp about making cider:

A comprehensive description of good and bad ciders from a technical, simple flavour chemistry, and hardware viewpoint. What different apples do for the taste of a cider, what goes into a real cider, how real cider is made, and then by contrast how cheap cider is made. This talk is based upon four decades of cider making experience growing up on a British small farm.

One of our esteemed and regular members Chris gave an interesting talk on Antiparticles and geiger counters at EMF Camp 2018. He built his own geiger counter and you can find his code on github here.

Geiger counters are interesting and surprisingly useful devices, and you can build one for less than the price of a video game. They can monitor background radiation levels, check household items such as smoke alarms and gas mantles, and provide information about medical treatments. I designed and…

Last wednesday we had the mayor visit the shed to have a look around. The visit was also documented by MK Citizen and made the front page of the paper edition.

They were impressed by the 3D printers we had built and Paul designed a key ring with the Mayors name on it for him to take away. Here’s a couple of picture:
