  1. I love Solari boards – the clickety-clackety electro-mechanical split-flap displays that were used as departure boards in railway stations before they were replaced by electronic versions ☺️

    It would be fun to have an old one, but I suspect they’re extremely hard to come by – I’ve certainly never seen them popping up on eBay!

    So I was pleasantly surprised to discover that a US company, Oat Foundry, makes character-by-character split-flap displays to order (not quite the same, but still fun): oatfoundry.com/split-flap/

    Very cool, but how much are they? Well, let’s just say you can *rent* their smallest one (3 rows of 16 characters) for a *week* for as little as $7400 😱

    That makes their competitor’s Vestaboard (6 rows of 22 characters) a complete steal at £3095 – to own outright no less (!): uk.vestaboard.com/products/ves

    The basic principle of split-flap displays is well explained in this three-and-a-half-minute video – you can see why they don’t come cheap: youtube.com/watch?v=UAQJJAQSg_

    For people with the right equipment (3D printers, soldering kit etc.) and corresponding skills, there are lots of DIY instructions for making split-flap displays – way beyond my level sadly!

  2. La #Cina domina già nelle #rinnovabili. Già nel 2020 la sua capacità installata, circa 895 GW, superava UE, USA e Australia messi insieme: ora decide di correre più veloce di chiunque altro, annunciando enormi impianti #solari ed #eolici nei suoi deserti.

  3. #Agrivoltaico e canali "solari" continuano a farsi strada. ne abbiamo parlato tempo fa (qualcuno storse anche il naso), ma la cosa produce risultati. Coprire i canali di irrigazione con pannelli #solari ha senso e funziona.
