Pipe Organ Desk With Programmable Pneumatic Logic Controller, Secret Compartment

I first wrote about Denver puzzlemaker Kagen Schaefer’s gorgeous purpleheart butcherblock benchtop two years ago, and now Kagen’s knocked me out again with this nigh-unbelievable desk.

The pneumatic lock can be reprogrammed to recognize any melody. Holy smokes.

We have covered Alan’s Biocca’s fantastic clearinghouse site antennalaunchers.com before, and Brookfield, CT, resident Andrew Stoev’s basic launcher design appears to be a slightly up-gunned version of Alan’s CSV19 pneumatic antenna launcher. It’s a beautiful build, but my favorite feature is the quick-release mount he added for his Android device. Using a free app called GeoCam, his phone, when so mounted, becomes an augmented-reality aiming scope that provides GPS location, compass orientation, and (probably most usefully for this purpose) phone inclination data.
