I created this one for camping and balancing the tires on the go but it wasn't functional so much, maybe a bldc motor and lipo power source make it more handy tool when compared with it's weight to feature.
Cost: build with existing materials, only paid for pump which costs around $25 and pressure switch $100 but it was completely unnecessary purchase hence i didn't hit to 10 bar yet.
features:
Power source: 12v motocycle battery
Max. pressure: 8 bar
Capacity: 2liter
Features: thermal protection, fan-cooling
