@skyfaller so, for you, the Fediverse is about Mastodon?

More like Losesome Earle-Sears, am I right, folks? (I'll see myself out.)

@stefano The people who demand moar powerrrr really need to drop their current workstation for a 266MHz Pentium 2 with 32MB RAM and a 5400 RPM hard drive.
That will force them to design better code. Or pick a different career field altogether. ๐คฃ

I'm feeling FOMO for SFSCON this week and TPAC next week.
One thing about being part of the Fediverse movement is that I have a lot of confidence in friends and colleagues who will be on the ground doing good work.
Thanks for everything you do, ActivityPub allies.

you, smug: "oh you like $thing? how cute! if you're lucky you'll realize $other_thing is better"
no one: "oh you sound like a pleasant person to be around! please tell me about $other_thing"

A Paintball Turret Controlled Via Xbox Controller
Video games, movies, and modern militaries are all full of robotic gun turrets that allow for remotely-controlled carnage. [Paul Junkin] decided to build his own, albeit in a less-destructive paint-hurling fashion.
The turret sits upon a lazy susan bearing mounted atop a aluminium extrusion frame. A large gear is mounted to the bearing allowing the turret to pan when driven by a stepper motor. A pair of pillow block bearings hold a horizontal shaft which mounts the two paint markers, which again is controlled by another stepper motor to move in the tilt axis. An ESP32 microcontroller is responsible for running the show, panning and tilting the platform by commanding the large stepper motors. Firing the paintball markers is achieved with solenoids mounted to the triggers, which cycle fast enough to make the semi-auto markers fire in a way that almost feels like full-auto. Commanding the turret is via an Xbox One controller; communicating with the ESP32 over Bluetooth using the BluePad32 library.
Itโs worth noting you shouldnโt shoot paintballs at unsuspecting individuals, since they can do extreme amounts of damage to those not wearing the proper protection. Weโve featured a great many other sentry guns over the years, too, like this impressive Portal-themed build. Video after the break.

wish more people realized that smugness makes for poor tech evangelism
