The 23b Shop is a (highly) mixed industrial hacker space. We work on a large range of projects including automotive, motorcycle, 4x4, guns and reloading, computers and networking, electronics and microprocessor projects, metal casting, machining, fabrication of all kinds, welding, leatherwork, jewelry, and knifemaking.

If you are used to living in your own greasy unilluminated cave, this place is a VERITABLE WONDERLAND of creature comforts -- the treehouse you wish you could have built as a child is here at last, and full of pudding....

Shop Floor Area
Lots of hand and power tools
Roll-up door for BIG WORK
SMT-grade electronics test bench and quasi-clean area

We may be rough 'n' tough shop guys, but we also have many upscale, grandiose amenities for the faint-hearted! If you're some geek's 'normal' partner who got dragged in here against your wishes, you may survive for several hours... but you will be far, far away from friends and home, and possibly from comfort, and definitely from a warm shower. We like you, really, but please plan accordingly and bring a book or something. (or pick up a tool and learn a new thing)

the PURGATORY BIN (Sing along right now!)
Bring your crap and hurl it in
our Weighted Purgatory Bin.

Then haul some to your Lair of Sin --
we shall not take it back again.

The thing you covet, take it, man!
Before it hits the garbage can.

No trip is complete without a whirlwind tour of the PURGATORY BIN.

Shop for FREE in our pro-grade castoff gear and scrap pile!

Grab what you want before someone else does!
TRUST NO ONE! with your precious new TREASURES

Sometimes the Purgatory Bin offers you fine electronics, working gear and computers from all years; honest, good gear lost to its prior owners, but awaiting a new start in your life.

Sometimes it gives you a sandwich from 3 weeks ago, still untouched in its plastic tomb, taunting you silently from beyond the grave.

Some days it's got cables, funny metal bits, odd scraps of cloth, hardware, software, books, naughty books, working gears and parts, engines, or other weird things of all descriptions.

You can't be sure with the Purgatory Bin -- it's wily and elusive in its way, but it loves you and wants you to savor its wealth.

The only guarantee is YOU WANT IT. At least something in there should make you happy. GRAB THAT THING RIGHT AWAY, IT'LL BE IN A LANDFILL THE NEXT TIME YOU SEE IT.

You may also simply leave your car open and unattended for a bit, and we'll be happy to provide
you with our premium Personal Shopping Service, at no discernible cost, with no notice whatsoever. Our History

The 23b Shop itself was founded in 2006, but we have been getting together for over 20 years now.

The 23b Shop came into being after we found ourselves gratuitously gravitating towards our garages to work on robots, cars, rockets, electronics, melee weapons, and other projects whenever we had a party (or every night, pratically..)

We put together a cunning plan, then spent 3 months looking for a site that was both good and affordable. The result was the 23b Shop, located near the Fullerton Metrolink station near the throbbing heart of downtown Fullerton.

We are a VERY active hackerspace, with lots of ongoing projects. (Just come down already and try to stump us on your project, or bring us something we've never seen before.) We offer a wide range of tools and equipment for the mad scientist within our modest space. Also, pudding.

Donating to 23b Shop

The 23b Shop is open for everyone to use when a keyholder is present. Core members (keyholders) chip in for the rent and expenses at US$200/mo.

Financial donations to the 23b Shop Fund pay for the carefully hoarded shop supplies upon which we rely for our daily safety, and which you have so cruelly squandered during your visit. Simply add the contribution of your liking to the Shop Fund when you visit, or catch us next time, or sweep up and help out with chores if you prefer.

Donations of working equipment and supplies are highly prized. Just like a colony of Manchurian Wedge Ants, the industrious hackers of 23b Shop will lovingly snip your donations into pieces with tiny razor-sharp zircon encrusted mandibles. Hackers often carry up to 700 times their own weight in used electronics straight up the walls and ceiling of the shop, scurrying to place the gear safely in nest chambers. Once deposited in a nourishing layer of filth and sweaty Defcon Goon shirts, it will be used to feed the next generation of unicorns and kittens, and to polish the majestic Shop Narwhal.

23b Shop creates objects of stunning beauty and ruthless efficiency from your disused toys, machinery, serapes, electronics and electrical kit. We use your castoff structural materials of all dimensions to build fantastical devices like the Mobile Club, and invite hackers the world around to come in and play with new techniques to build the ideas festering in their oddly shaped heads.

Your donations of cash and gear are gratefully accepted and encouraged, but a donation is never required to use the 23b Shop within reason. Your donations help others play and learn better.
