Tomorrow night is another hackerspace, and we know what we want out of it – a live system up and running in City of Edinburgh Methodist Church. We won’t have access to all areas because it’s in use, but we should be able to do all but set it up. Hope to see you there, 7:30, all welcome.
Main event: Friday, 14 November 2014, 1:30-5, City of Edinburgh Methodist Church, 25 Nicolson Square, Edinburgh, EH8 9BX
Optional introductory lecture: Tuesday, 11 November at 10:00, University of Edinburgh King’s Buildings – Hudson Beare Building, Classroom 4.
The thermostats that control our heating systems measure air temperature, but that’s not the only thing that’s important for making sure people feel comfortable. Standing in the sun is hot because the sun is warmer than we are and transfers heat to us by radiation. The surfaces all around us act in exactly the same way, and are just as important for how we feel – especially in buildings that are only heated some of the time, where the walls can be very cold. In this challenge, we will attempt to build black globe thermometers for measuring “mean radiant temperature” (see Nova Lynx and Campbell Scientific for examples). We’ll form teams to mix the skills required and equip them with everything we think you need for a basic design – temperature sensors, Arduinos and Raspberry Pis, coat hangers, cake tins, soldering, heat shrink plastic and plenty of black matte paint – and bake a cake as a prize for the best team. If you have time, you can attend a brief introductory lecture to hear more about black globe thermometers so you can think ahead about design improvements. You won’t be able to take the thermometers home afterwards, but we will use them to understand Edinburgh’s church and community spaces and show their readings on our website.

The next time we’ll get together is now Tuesday, 28 October, not 14 October (which we advertised on the web for a little while). We’ll be working on setting up temperature and relative humidity monitoring for the Methodist church organ, and maybe by that point we’ll be ready to stick up a system in Christ Church Morningside as well. It’ll be nice to see anyone who is interested there.
