After several weeks of working hard, my OnlyFan's PSU has given up and gone to the electronics graveyard in the sky. After taking it apart it I found it needs 12 volt power, so after finding an old plug-in power supply and a connector, its going to be keeping us cool for the rest of the heatwave.

Another wet weekend so "out" for a nice sunny ride on #rouvy on the bike trainer this morning

Updated the iphone today and it asks for your credit card for #ageverification to confirm you are over 18. As I've used apple products since the iphone 3 which came out in 2008, I would have thought they know I have been over 18 for a long time :(

After a winter riding indoors on Rouvy, its nice to dust off the outdoor bike and take it out for our local loop around the Isle of Purbeck and try to avoid the potholes in the badly damaged roads.
