Gutted. I've listened to TMM for at least 8 years on a daily basis and it's been a massive source of new music for me 😥

Random observation of mine but I reckon lots of families who would normally go overseas for their September school holidays have stayed in NZ and have gone skiing instead

A webcam screenshot of Cardrona ski field showing it absolutely heaving with people. In previous years it's normally fairly quiet at this stage in the season

Super impressed with the SigEnergy gear. Dumping both the solar and the battery into the car is awesome

Tonight's adventures in geekery

A smart switch is held in electronic helping hands while multiple wires are connected to it and then to a USB to TTL connector installed in a laptop

The final result which is firmware that only talks locally rather than back to overseas. Instant integration with Home Assistant for those in the know

Significant GPS spoofing / jamming going on over Poland in the Gordon Bennett gas balloon race. The Swiss team seems to have grabbed the longest possible path. live.gordonbennett.aero

Our newly added string of West facing panels is certainly assisting at 4:30pm

Lunchtime walk around the block Wanaka New Zealand

Being able to both run the house from the car in an emergency or dump 25kWh into the car if required is awesome

After two attempts to get into Queenstown yesterday we got flown back to Auckland with a fuel stop in Christchurch. Let's hope the landing is more successful this morning...
