The good folks at Domeorama have got all your geodesic needs covered in a thorough and awe-inspiring list of all the different kinds of geodesic hub connectors you can buy:
This is the classic way to connect geodesic struts together. A hole is drilled in the flattened ends then bolted together.To accommodate a drilled hole into your struts, the length of the strut needs to be longer.For example a 36 inch pipe/conduit strut will need to be extended at both ends to drill holes. A rule of thumb is to add 2 X 3/4 inch = 1.5 inches (or about 8cm) more to all struts. That means the center of the holes would need to be drilled 3/4″ from each strut end.
...This is another way to attach geodesic struts together to form a hub. Inexpensive and something you can do yourself, this hub has 5 bolts instead of just one, so very solid. Keep in mind you need to cut your struts accordingly: since connections are vertex to vertex, the total length between centers of the round tube needs to be the length of your strut that was calculated. In other words, your real length will need to be longer because ends are bent.

Earlier this month, I gave the afternoon keynote at the Internet Archive’s Decentralized Web Summit, and my talk was about how the people who founded the web with the idea of having an open, decentralized system ended up building a system that is increasingly monopolized by a few companies — and how we can prevent the same things from happening next time.
Designer Art Donovan writes, “I’m always looking for new and unique inspiration for my lighting commissions and the latest, cutting edge scientific devices offer a boatload of great design inspiration. From the cool, new ‘James Webb Space Telescope’ to the myriad of complex details in the L.H.P.C. at Cern- it’s a cornucopia of rich imagery.”
Some truths are universal. For one, your phone will always run out of power when you most need it. For another, the charging cords that come packaged with your Apple device will fray, split, and rip faster than Usain Bolt in a game of tag.Instead, pick up a charging cord that anyone would have a tough […]
Some people say magic tricks are nerdy and best left to your 12-year-old asthmatic cousin. But others see value in perfecting the slight of hand and showmanship associated with a perfectly executed routine. We’re firmly in the latter camp. And now, we’re giving you the ability to put a few parlor tricks up your sleeve with the Penguin […]
Bluetooth speakers may be convenient to use, but many of them just aren’t that powerful. Sure, it may be fine if you’re seated in front of the speaker. But move across the room, and you may strain to hear what’s coming from those tiny drivers.There’s a reason why the G-BOOM Wireless Bluetooth Boombox (now $79.99 in the Boing […]
