Added a PoE switch to the roof, and a small switch for the shop floor at 23b.
Small keystone jack with RJ45 ethernet under a wall shelf for easy temporary access wired network for the 23b shop. A UniFi Flex Mini switch under a wall shelf with four 10ft. Cat6 patch cable connecting the switch to the easier to access keystone jacks. The roof of the building, with an antenna pole in the center of the frame. A utility box mounted to the pole houses a UniFi Flex Utility switch to provide PoE access to other devices on the roof. A Ubiquiti Rocket dish is also mounted to the antenna pole. A close up of the clear door utility box mounted to the antenna mast. Cable pass through glands are mounted under the box with cables attached to the switch inside the box.

I wouldn’t recommend it, the original case is much sturdier and you lose a mount point for the primary m.2 port. But the thermals were slightly better.

Having an 8th gen i5 with 8GB of RAM makes this thing quite overpowered for my use case.

If I could only afford more storage!

I guess it’s my turn to #makeshitmonday since
@elcannibal.bsky.social hasn’t yet.

I decided I need a portable video server, since we travel to places with intermittent signal and limited internet.

This is a #Lenovo M90n fitting perfectly inside a VHS tape

Had a great turnout for OC2600 on Friday, with over 70 individuals from all over Southern California showing up!

We had a few ad-hoc activities, like tearing down a PlayStation 5, another rebuilding the Kubernasty with upgraded Chromeboxes. Lots of student cyber clubs sharing notes.

In the process of upgrading the network at 23b. We resurrected ID4con (since it coincided with OC2600), @zhoratrope.bsky.social finally got to play with steel wool poi, and painted some bricks.

Should have come to ID4con at 23b.

In an attempt to test a few laptops for a DEFCON village, I put together a small CTF for Irvine Underground (laptops were fine, but the CTF didn’t actually work). Also trying to figure out storage options for a local competition group.

Rooted some Android board in a check in kiosk. Installed more servers in a student club rack. Did a mile WiFi shoot at the beach with the CSU* students with the Linksassy.

Reworked the Kubernasty Cluster. Bunch of stuff either broke or did not work properly… but it’s back up and running.

Probably the last install-fest for this iteration. I have upgrades waiting. But once more unto the breach.

A contingent of Orange County hackers descended upon the 23b Shop for a night of installing a portable Proxmox cluster with me. How else would you spend a Friday evening?

The Southern California hacker community is thriving!

Come join the meetups and hang out with like minded people.

I’m also the one who came up with the idea and hacked together the hardware for the Shell On Demand Appliance (S.O.D.A) machine. A fully independent virtual machine host inside a Dixie Narco vending machine.

The software was developed by @balsa.info.
A vending machine with a rainbow of LED lights in the selection panel of nine button options. The flavors are all replaced with Virtual Machine guest operating systems. A vending machine opened to reveal a server rack vertically mounted with four Dell R630 computers that host virtual machines for the Shell On Demand Appliance (S.O.D.A.) Machine. The door has two thermal printers in the center hole originally used for removing purchase drinks. Stickers embellish the sides of the machine. A drink vending machine with green lights on the buttons. The front door signage has “Cold Drinks” in white text on a blue background is backlit. Next to the machine is five 24” LCD displays stacked on to of one another showing a user interface and vitals of the servers inside the vending machine. A thermal receipt from the Shell On Demand Appliance (S.O.D.A) machine. The text on the receipt shows the IP address and credentials to log into the virtual machine being hosted inside the vending machine.

I’m duald. One of the @defconscavhunt.bsky.social judges.

Played ScavHunt DC14. Started judging DC18 and have been ever since.

I help keep the old school DEFCON vibes alive with my team. Over the years we’ve brought many of our projects and functional art to the table for everyone’s amusement.

A Tickle-Me-Elmo is between them with its outer fur missing revealing a hideous robotic-like body. Below is a speaker made from an old 1970s hard shell luggage case. A video set behind the DEFCON Scavenger Hunt table with two chairs against a black backdrop and between two fake bushes to resemble the series “Between Two Ferns”.

I suppose I should introduce myself here, in case you run across this account unfamiliar with my shenanigans.

They practically fall off trees here. Ask a friend or acquaintance if they’re getting rid of one. Dumpster dive. Or if you really must transact currency, find a reseller/ewaste company that can sell you one for cheap.
