Portable mini usb air compressor (for inflatable bed)

thingiverse

When I hit the open road on my motorcycle, there's no room for extra gear. I used to get frustrated when inflating this inflatable bed, especially after a few beers - I'd end up dizzy! Now, with this setup, I can enjoy blowing it up without breaking a sweat. Extra equipment includes: 1 x DC motor from an old toy, likely running on 3V but capable of functioning at 5V via USB power for a short time until the bed is fully inflated 1 x Switch to control the motor's operation 7 x Screws to secure everything in place 1 x Old USB cable for connecting the motor to a power source 1 x Capacitor (500uF) to regulate the motor's current flow 1 x Capacitor (104) to filter out any electrical noise Make sure your USB power bank can handle the motor's high current draw - mine consumes about 1.3A.
