JawnCon 0x0: A Strong Start With A Bright Future

November 13, 2023 by Tom Nardi 9 Comments

Last month, I had the pleasure witnessing a birth. No, not of a child. What I’m talking about is something far rarer, though arguably, just as loud and danger fraught — the birth of a new hacker convention.

The very first JawnCon took place on October 19th and 20th at Arcadia University, just outside of Philadelphia. If you’re in the Northeast US and suddenly find yourself surprised to learn that a hacker con managed to slip under your radar, don’t be. The organizers, who previously helped launch the WOPR Summit back in 2019, wisely decided to keep the scale of this first outing in check. Just a single track of talks, a chill out room, and 130 or like-minded individuals.

Although, even if they’d hatched a more ambitious plan, it’s hard to imagine they’d have had enough time to pull it off. Due to various circumstances, JawnCon had to come together at a breakneck pace, with less than 100 days separating the con’s inception and kickoff. That an event such as this could not only be organized so quickly, but go off without a hitch, is a testament to the incredible folks behind the scenes.

As for what a Jawn is…well, that might take a bit more explaining. It’s regional slang that’s perhaps best described as a universal noun in that it can be used to refer to basically anything or anyone. Think “smurf” or “da kine”. According to organizer Russell Handorf, the all-encompassing nature of the word describes not only his personal ethos but the spirit of the event. Rather than focusing too closely on any one aspect of hacking, JawnCon set out to explore a diverse array of tech topics from both the new and old schools. It would be an event where you could listen to a talk on payphone remote management, try your hand at lock picking, and learn about the latest in anti-drone technology, all under the same roof.

To that end, the team did an incredible job. Everyone I spoke to, young or old, newbie or vet, had a fantastic time. What’s more, as revealed in the Closing Remarks, the con actually managed to stay in the black — no mean feat for a first attempt. With a little luck, it seems like JawnCon is well on its way to becoming one of the Northeast’s can’t-miss hacker events. Continue reading “JawnCon 0x0: A Strong Start With A Bright Future” →

Larger-Than-Life Game Of Operation Is The Future Of Healthcare

September 21, 2019 by Mike Szczys 13 Comments

It’s hard to beat the warm memories of Hasbro’s Operation, a game that boils down the fine art of surgery to removing farcically named plastic bones and organs. Just in case you can’t conjure up the memory, the game board looks just like this huge version of it, but normally sits flat on the table and is no larger than… well, a board game. Players take turns using a tethered tweezer to remove butterflies from your stomach without touching the metal sides of the incision area. If the tweezers touch the metal, a buzzer goes off and the player loses a turn.

Of course, we now live in the future and robots do our difficult surgeries while the talented doctor looks on from a video console. So, [Ben] and [Jonathan] built themselves an oversized upright version of the game that includes a CNC-wielding surgery robot.

Delightfully, the controls are designed like a coin-op arcade machine and the three-axis CNC machine they’ve built is a new take on the claw machine. It has a gantry that moves left and right, a head that moves up and down along that gantry rail, and an actuator that moves in to snatch those pesky organs. Limit switches cut the power to the motors if the axis moves too far.

Pieces are foam and hang from a coat-hanger hook

In true robosurgery fashion, there’s a webcam that goes along for the ride to give the surgeon a close-up look. Just stay away from those edges! There’s a button on the tip of the actuator that sets off the alarm if you miss the hole and hit the surface of the board, thereby ending your turn. Each organ is made of foam, faced with a piece of sheet metal, and hung from a hook made of coat hanger wire. That sheet metal allows the gripper to use an electromagnet to pick each piece up.

The project is called Sergio and you can see it demonstrated in the video below. We first met these hackers last fall at Maker Faire New York when they were showing off a giant Connect Four game where you play against the computer. It’s nice to hear they’ll be exhibiting Sergio at Philadelphia Maker Faire two weeks from now.

HOPE 2008: Community Fabrication

July 19, 2008 by Eliot 4 Comments

Today at The Last HOPE, [Far McKon] from Philadelphia’s Hacktory presented on community fabrication. Over the last few years we’ve seen a lot of different accessible rapid prototyping machines created. There’s the RepRap, a fabrication machine that has achieved self replication; our friends at Metalab have gotten their own version of the machine running too. The Hacktory has recently acquired a Fab@home machine. Fab@home hopes to make manufacturing using multiple materials accessible to home users. Multiple materials means people have constructed objects that vary from embedded circuits to hors d’oeuvres. We can’t talk about edible prototyping without bringing up the CandyFab machine, which fuses sugar. The Hacktory has enjoyed their machine so far, but have found the learning curve fairly difficult. While it’s great to see the cost of rapid prototyping dropping, we’ll be much happier when the ease of use improves.
