Making a USB desk fan from spare CPU fan

If I wanted to make a USB desk fan from a spare CPU fan (input: 12V, 0.15A), could I just solder a resistor to the positive lead of the USB wire? I plan on getting an adjustable voltage booster, but I was curious if this was possible. I think I would need a 13 ohm resistor for USB 3.0.

Worst social media communities in sites in order, in your opinion?

By “worst”, I mean most toxic, most misinformed, most discriminatory, etc (not related to the owners of the site, e.g. Elon throwing out the trash by adding ratelimits).

Can anyone suggest a 'SP3T' Toggle switch?

I am looking for a Toggle switch that will allow me to actuate an actuator manually, or otherwise set the actuator to an ‘automatic’ mode, logic for which which I am coding on an arduino. The switch I want should have momentary On’s for manual trimming that will spring back to an Off position, or it can be left in another...

555 based PWM Dimmer not working only with LED strips (discuss.tchncs.de)

I bought a PWM Dimmer based on a 555 from AliExpress to regulate the brightness of a 12V 1A 1 meter LED strip, I already built one myself years ago on a perfboard but this one was the exact dimensions I needed for a project. I built mine from components from AliExpress and components found in old electronics so I thought nothing...
