Heathack

 

tweety-pi-300x225As part of Science of Church, City of Edinburgh Methodist Church and Christ Church Morningside hope soon to start running a “hackerspace” for church-based projects.   They expect to start by designing an electronics project that lets you monitor the temperature and humidity and send the results live to a website or phone or old laptop screen mounted on the wall, but then, they”re up for all kinds of related stuff, as long as it’s interesting, fun, or helps people understand how churches work.   We’re already starting to gather people who like science and making things, and to experiment with Raspberry Pis and Arduinos.

For more information (eventually!), see Heathack.

Meter Readings

meter-captureAs part of the engineering MSc project, we’re just looking at how to get frequent meter readings in a number of Edinburgh churches.  This is the set up for one of them:  an old Nikon mounted on a window squeegie.  A Raspberry Pi is driving it to take time lapse photos every 10 minutes, but we could have used an old laptop.  This won’t work everywhere – it requires good clearance around the meter for safety reasons, as gas and electrics don’t mix – but for some churches it’s a cheap and cheerful option.  The student will be using the data to understand thermal comfort and heat loss, but it is also useful for getting a sense of what it costs to run the premises under different circumstances. nikon-on-old-pole pi-meter-capture
