Works great imho. The folding mechanism is ingenious. Can it lift a few grams, e.g. a small battery box?

It kind of depends on the macOS you are using. If you upgraded to macOS Catalina (10.15) you can‘t use the Mac app anymore. Since the app is written in 32bit code you have no chance of running it on Catalina Macs.

Is this supposed to be for same kind of lathe? The kind thar locks pipes or ring shap material from the inside.

@Ivan_M Thanks a lot for those images. They'll help me a lot. I'm trying to built a slim custom actuator for the GMK6400.

This is one cool crane. This custom linear actuator is quite interesting. I wonder if you could provide some more detailed images? Especially the mounting on the upper carriage interests me a lot.

I think the project is still alive: https://www.fxbricks.com

I'd like to propose a "Universal Set" contest. "Universal Sets" were great in the 80s. They got my started into Technic. Brickset got a list here: https://brickset.com/sets/theme-Technic/subtheme-Universal The task could be: Design a Universal Set with a given number of parts. At least 3 models have to be designed using those parts. The models should using different building techniques and display different mechanical principals.

That's a really nice truck. Looks like a lot of fun to play with. One captions states a speed of 19km/h at 9.2V. Doesn't the Buwizz allow up to 11V? Did you take the truck for a run in thar ludicrous mode?

It will be hard for 3rd parties to develop adapters to connect PF stuff. The PU connectors are patented. If TLG refused to licence them, we getting the same scenario as with Apple and its depreciated MagSafe power plug.

Cool. I‘ve seen those in sawmills and wood trading warehouses. They look somewhat strange bugbane quit interesting. Great MOC.

Hopefully. Usually, the price for B&P is somehow directly related to their weight. The Claas tires cost 5.12€. The Tumbler tires were about 7,50€. A small Mini Sai piece is 0.12€. Maybe the driving ring extension is made out of some kind of unobtainum. ;-)
