Cupboard in house where Pfsense router, fibre media converters and other such stuff lives. Power-cut early this morning. I can handle no fridge, no cooker, no shower, but no internet, well that's just pushing it too far! Found my old workshop server rack UPS, batteries still

Out running an errand in the car, always a joy to see the edge of the Grampian Mountains on a nice day just a few short miles away. Blue dot is where I live, the red arrow is the photo location.

My old homemade balancing-bot out of storage. Arduino controlled, based on 6 DoF (six degrees of freedom). It worked....kinda! Missing the motor driver, but it's time to strip it down fully for bits (I'm on a workshop tidy-up binge).

My local town has a town square open day (Feein' Market Day), lots of stalls etc.....and the local fire brigade had along one of their fire engines so I got up close. Had a good chat with a fire fighter about the pumps, the pneumatically operated valves and the control system.
