The 23b Shop is open for everyone to use when a key holder is present. Core (key holder) members chip in for the rent and expenses at US$200/mo. Donations are always welcome but not required.
General Layout of the Shop


Founded in 2006, the 23B Shop came into being after we found ourselves always gravitating towards the garage to work on robots, cars, rockets, electronics, melee weapons, and other projects whenever we had a party. We put a plan together, then spent 3 months looking for a good site that was affordable.
The result was the 23B shop, located near the Fullerton Metrolink station near downtown. We are active with lots of ongoing projects and offer a wide range of tools and equipment for the mad scientist within our modest space. Also, pudding.

Thanks to the generosity of two of our Desert Dog members, we have now upgraded the electronics lab with a stereo microscope, a new lab power supply, and advanced SMD soldering capability.

10/2/2009 4pm on - Arduino User Group Meetup

Interested in building smarter projects using the Arduino or other microcontroller? We're hosting the first of several Arduino meetups. Come on over, starting around 4pm and bring your project. Tell a friend!

9/12/2009 - 9/15/2009 Hacker Space Documentary

Bilal, Jordan, and Paul from the Two Hands Project will be in town to film their Hacker Spaces Documentary. You will probably see them around here, and they hope to get tours of as many spaces around L.A. as possible. Come help them out!

9/12/2009 CP Going Away Party

CP from Defcon 949 is moving to Maryland! Come see him off at this fantastic party, which starts at noon and goes until we feel like it.

6/17/2009 - 7/31/2009 The 23b Shop Blog

The 23b Shop Blog and photo site is now operational. Check it out here: shop.23b.org. Check here for projects, photo galleries, and general ranting.

8/13/2009 Defcon wrap-up and news

This year's Defcon was a success once again, despite almost continuous cock-blocking by our host hotel. The mobile disco performed beyond expectations, although the air cannon got damaged in transit. A couple of things to bring up:
1. We are still missing the water cooler. If anyone knows who brought it back, please contact Kallahar (kallahar @ kallahar.com). Update: We found the water cooler. Actually, we found out that we lost it. Oops! Replacement is on the way...
2. It's time to clean up the shop once again. I'm going to tentatively suggest a shop clean-up day and party for the last weekend of August.

6/17/2009 - 7/31/2009 The 23b Shop Blog

The 23b Shop Blog and photo site is now operational. Check it out here: shop.23b.org. Check here for projects, photo galleries, and general ranting.

6/17/2009 - 7/31/2009 Open Shop Days and Defcon Preparation

The Defcon hacker conference was a success. We had the 23b shop opened up almost every Saturday and Sunday for the month working on projects such as the Beer Chiller, Mobile Disco Club, and Super Ultra. Thanks to everyone who stopped by to help and say "Hi!"

6/17/2009 Creepy Estate Sale

We spent about 3 hours digging through the garage and outbuildings at a creepy old house in O.C. We were able to score a bunch of new specialty hand tools, a Helium tank, an O2 set, lots of misc. hardware and some camping stuff. Also got a large cabinet of taps and dies for the machine shop area.

5/23/2009 LayerOne

The LayerOne hacker get together was a success. We hosted the Sunday after party, and had at least 75 people there. The "group feeding" project involved 10lbs of spaghetti and the ubiquitous turkey fryer we use for home brewing. Look for a return of this at Defcon next month. Thanks to everyone who worked on the Phone Booth Bar, shop cleaning and other preparations. Thanks also to whoever left the 2 cases of Sam Adams and Pacifico.


Shop Improvement Day: Thank you eris, tacitus, arclight and danno for helping clean and make improvements to the shop last weeend!
  • We added a vent hood to the welding area that vents outside.
  • We ran new network cables for the neighbors
  • We converted the upstairs to a chill out area. We need a big throw rug or remnant carpet still.
  • We got the bathroom and office cleaned very well!
  • Also added some new art and decorations.

Thanks again everyone who participated.


Update: HackerSpaceSD will be visiting on Saturday, April 25th. We are planning a regular open day for projects, and welcome our new guests.


Update: 23b Labs now has a reciprocal agreement with BlackLodge in Seattle, WA. BlackLodge members get free use of the lab while in town and discounts on workshop fees.


LayerOne Hacker Conference is coming to town. Expect a 23b event on Sunday night.


The party was good. Tacitus installed HAM radios in his Jeep, there was homebrew and Clown Bike Jousting.


Got the new lathe hooked up and running true. Danozano may be doing a jewelry class soon. The robot arena is built and battle tested, and Arclight has dusted off the Aluminum/Brass foundry, so that is once again operational.

Cutting a 60T gear for a music box


Happy New years! The New Years trip was great. Check out pictures on the Gallery.


The shop improvements are going well. Flea's workshop was a hit. His workshop on leveraging Craigslist for serious relationships really opened a lot of eyes.
