My great grandmothers were: Lola, Layla, Eula, Lulua. For real. They were born around 1900.

We have a cat named Lulu.

This is so stupid. It cracked me the fuck up. The kid and I are sitting giggling like a couple of morons.

Dikes or pair of dikes also refers to diagonal cutters. (Look like pliers with blades instead of jaws at the end) They are used for cutting sheet metal, also, wire cutters are also called dikes. Can also be used as a verb: Dike off the corner of that piece of steel, or, dike out that part of the circuit.

My wife is bi and it always messes with her when I say it. Just a trade term.

Oh jeebus fucking christ. Sometimes the dumb hurts and then you get the existential dread knowing you're about to have to call this moron. And, even better, they usually make more money than you.

Circuit is for controlling the fan on a Raspberry Pi, just on/off according to temp, no PWM. Not sure about the diode as it has a .7V drop and it's a tiny brushless DC motor. No markings on the fan so I measured the current with a multimeter when hooking it up to a USB charger. Circuit was adapted from here using what I have on hand.

Suggestions? Any advice is greatly appreciated!

*EDIT: Confirmed, this circuit works on a Raspberry Pi 4. Base was wired to GPIO 17 and manually tested using commands:

raspi-gpio set 17 op dh

raspi-gpio set 17 op dl

I didn't use a breadboard, just hack-n-slash with the wires coming out of the fan, the leads on the thru hole components, a jumper connected to gpio 17 as a socket for the base/resistor lead, and heat shrink tubing for insulation. Folded it up as I closed the housing. Case combo including heatsinks and fan here.
