cave art …

No trip to Perigord is complete without a visit to see the (replica) parietal wall paintings at Lascaux dating back to the Magdalenian era some 20,000 years ago i.e. about 15,000 years before the Egyptians figured out how to build pyramids and long before the Chinese worked out how to eat with two bamboo sticks. Artistic composition, IMHO, hasn’t progressed much since 😉

project hydro …

Catching up on last Bank Hol’s project: hydroponics. Found some strawberry runners / stolon in Alsace and planted them in the kit (no medium, just rock wool for support) which took nearly a month to arrive 😞 Yet to connect the pH and TDS / EC monitors to the Pi Zero (seems the cheap sensors I bought only output analogue so order is in for an ADC). Anyway, the babies are still looking quite happy on Day 2 😉
