okay; now that we have that remote black-box RE'd; let's cheat a little, and open the remote up! ^_^

The remote's PCB is ultra-simple-- it's literally:

- a single EV1527 control IC
- four buttons
- four diodes
- a crystal
- a switching FET
- an LED
- a PCB antenna

We can guess a lot of this by looking; but it turns out we don't have to-- we can pretty easily grab a schematic!

Okay, as promised, it's time to live-tweet as I "quickly" reverse the RF protocols associated with this wonderfully-named JOOFOO floor lamp:

The lamp's pretty bright; but it's defining features are accessed via a small remote control. The remote allows one to adjust the lamp’s brightness and color temperature— and despite having no FCC identifying label, seems to communicate over RF.

At a glance we can guess this slightly dopey looking remote uses a simple modulation in one of the ISM bands.

so, my body doesn’t produce sex hormones on its own (and hasn’t, based on a long history of lab tests); and if I don’t inject synthetic ones myself, I’m super exhausted all the time

(this is probably related to an intersex condition, but I’m super hesitant to apply labels) CW: consequences of bad politics

the bad political state of the US recently has made me increasingly worried that some of these meds would be less available, as they’re often used for birth control — and for trans care

i *really* don’t want to go back to being eternally tired

a few years ago, at the virtualization company I worked at:

customer: ever since we installed your new GPU driver, excel has been coming up with... wrong answers
me: wait what
customer: here, watch
me: how the *fuck*

bonus points to the first person to guess how that happened background:
- this was a Windows XP driver (XPDM)
- there was no GPU compute involved
- only excel showed any kind of weirdness at all; everything else was perfect
