Thanks Kevin, i didnt used hubs and its a 4V frequency but wasnt too easy to build and i had challenges that led me to invent a tool for measuring the compond angles at the joints.I will put foil on interior like you have that reflective one but il use transparent and for the whole dome.
Mark,those mail order bees can live quite a long time,you only have to feed them a little pollen pattyes and sugar water .I will catch my own queens from the wild and start the colony and if they make new queens ,il keep those in the fridge and release them in nature in the spring.Greenhouse polycarbonate with double walls its what i will use,the type that has a side treated against UV.As for the RO system( reverse osmosis water filter) the last i have build for my saltwater aquarium ,i made it with cheap chinese membrane and its verry good ,after 3 Years it measures 15 TDS with old DI resin ( i have RO-DI) and ive been using it non stop.If you want to build your own to have nice resealable filter housings i can help with advices.At somme point i even toght to start making them and sale for profit.
Francesco,joints on my dome are interlocked and they just sit on on top of otther but they also have somme screws ,2 for each end of a strut that are on the lenght of it.But what keeps my dome together its the interlocking joints and 7 screws on the length of each strut.Il post pics with the joints in a few days .
