Portable storage for compressed air up to 200 PSI and maybe more
These parts give you freedom to store compressed air for small tools, without a compressor.
A common PC fan or similar brushless low-noise fan can be powered with USB (for 5 volts) or USB-C, using 5v, 9v, or 12v.
These 3 ingredients (plus pd trigger shown) power most small fans.
These are the selected parts as of 2025 that I believe will suffice to cover 80% of all possible inventions.
-
know the threads, where they are found, how they measure, how to tap & drill them,
-
know the methods to assemble & disassemble, and special tools (like the core removal tool for presta valve)
-
know the names for the parts & features, and typical appliances / part-families where they are found.

Coming soon! We have already built a number of items, they just need some time to be photographed. Then comes documentation & design info.
