NYC Resistor

What better way to spend a hot, humid Sunday Brooklyn afternoon than checking out Buzz-A-Rama, a 1960′s era slot car parlor in Kensington? Inside this unassuming storefront are 4 or 5 large twisting tracks, where children and adults race cars about 3 inches wide by 6 inches long, much larger than the matchbox-sized slot cars I played with as a kid. Amateurs like us use slow cars rented from Buzz. The pros, however, bring their own custom lightning-fast cars and controllers, and they are quite serious about them.

The car chassis are cut from lightweight aluminum composite using electrical discharge machining. Motivation is provided by high-performance brushless DC motors. Wheels and tires are made of special sticky, heat-resistant rubber, with a set of chemicals and rituals for cleaning and warm-up before a big race.

The lightweight plastic body can be either an aerodynamic wedge shape that directs airflow up, forcing the rear wheels down for better traction, or a more traditional scale model of a production muscle car. Super-cool retro body styles are available as well.

The controllers are also semi-custom built, and are adjustable by the operator to conform to his or her desired level of aggression in acceleration and braking.

Video of our presentation at Hackday:

In the video,

Ben Combee is speaking, Max Henstell is working the stabster’s pneumatics and Mark Tabry is standing by to protect bystanders, and I am off camera to the left looking pretty for the cameras.

Not in the video is Bill Ward, Charles Pax, as well as the original Max.

* Special thanks to my friend Adam from Twilio who provided us with some assistance in the effort.

For the blow by blow of the event check out our time lapse. Trust me it was 24 hours of tedium just as grueling as watching this 2.5 minute clip.

As you can see this was an pretty large effort by NYCR and a hell of a lot more went into this project than is readily apparent. Just getting the equipment there was an event all its own. Max and Charles worked tirelessly to repair Stabby’s pneumatic stabber arm. Max also worked on wiring up the actuators and accompanying arduino code to link up with Ben, Bill, and Marks twilio interface code base. I worked with Mark on a display that showed debug info from the arduinos ( blogarythmic cred ) as well as caller ( aka stabber ) id when stabbing.

We finished up about 5 minutes before time was called… literally. Came down to the wire. Stabby was awarded a runner up award, and supposedly will be on display at Tech Crunch on Wednesday some time during the day.

We had a hell of a lot of fun, and were excited to present a functioning project ( a first for me =P ). Even more exciting was winning a runner up award in a contest that didn’t actually have runner up awards. I guess they were afraid of being stabbed.

NYC Resistor was invited to exhibit our old Teletype Model 15 at Eyebeam’s MIXER event last March.  To make life interesting, we used a small Python program to grab tweets from Twitter matching the “eyebeam” keyword.  Watching a 50+ year old device once used to bang out the news of the day turn to printing the trivialities of the moment seems to echo the fate of professional journalists as the world’s attention span dwindles. To make things more interesting, we used a sentiment analysis algorithm to parse incoming tweets for positive or negative sentiment. The results were reflected on an old chart plotter. Positive sentiments moved the mark left. The middle of the paper represented neutral sentiment. Click the image for more photos and a video awaits after the break.

So, the folks over at Fubar Labs made a challenge to themselves and anyone else who wants to participate. Basically, write one program every day throughout the month of march. Any language, any function, but be creative. I doubt I can keep up the entire month, but it sounds like a really fun way to expand ones coding horizons and do some neat stuff. So anyways, here’s my first code for March Madness.

Edit: Thanks everyone who came out for the hackathon!

Here’s a semi-live shot of the hackathon at NYCR this weekend! Say hello internets.

NYC Resistor is saying goodbye to our old space, and what better way to wrap things up than with 48 hours of nonstop hacking?

Ok, maybe the real impetus is that we don’t want to have to move all this Club Mate to the new space. But regardless of our true intentions, it’ll be a great time to come and hack. We’ll have a plethora of electronics bits and bobs for scavenging, demos, and even a soldering lesson or two.

The awesomeness starts at 6pm on Friday, February 12 and goes until Sunday, February 14. We’ll end the event with a brief show and tell as well as PRIZES for the best hacks.

Participation in the hackathon is TOTALLY FREE, although donations are always super appreciated. Due to limited space, we are asking that folks RSVP, so click here to sign up for the hackathon.

Stay tuned for a more information! Additionally, we’re looking for a few good sponsors to help us provide snacks and other hacking necessities. If you or your business would like to be an event sponsor please contact Kellbot!

So at the end of last year and into the beginning of 2009, the folks at the extreme craft blog were soliciting for submissions for their 1000 ideas for creative reuse book. And since creative reuse is the very essence of hacking, I decided to submit my ( at the time new ) mp3 grenade project. It got into the book! So my idea is idea number 579 of 1000 fairly amazing ideas. Review and more after the click!

Bill, Alicia, Hilary, Diana and the Cake

NYC Resistor made a huge showing at Yahoo Open Hack Day NYC this year.  Team Makerbot showed up with the New York Toast, featuring their latest “Frostruder” prototype, an amazing attachment which turns the Makerbot 3D printer into a confectioner’s dream.  And in the spirit of edible technology, Alicia, Bill, Diana and Hilary gathered to create the “Delicious Cake.” The cake was, in fact, NOT a lie.

The Cake represents the sentiment – positive, neutral or negative – of a keyword as represented on Delicious.com, Yahoo’s social bookmarking service. The cake was made to look like the Delicious.com logo, and LED “faces” were used to indicate the sentiment. Hilary wrote the code for the sentiment analysis, Bill wrote the code that drove the Arduino controller, Diana soldered the LED faces, and Alicia assembled the electronics and decorated the cake itself.

You can see more of the cake at Alicia’s Flickr Stream or at Bill’s. We were also featured on CNN: http://bit.ly/ddNm3

So way back in the 2.4 Linux kernel days I operated a shell server. It was kind of like a “proto honeypot”. We set it up to portray a bunch of fake information about itself. We then released it into the wilds of IRC claiming it was a “machine we just owned here have a free account.” Then we monitored the systems use via ttysnoop applications and pulled copies of anything uploaded.

The result was we pulled about 4 gigs of exploit archives. And a bunch of logs of people trying to figure out why their x86 exploits weren’t running on the DEC alpha that was pretending to be the wopr.

Anyways, one of the neat side effects of my playing with the proc file system was finding a limit on the upper bounds of top. By setting up procfs to displays stats for 1048 processors I managed to get top to collapse after one iteration of showing cpu usage stats. Added a fun screenshot to the gallery.

Among the fun easy things you can do to tweak your kernel, upping your jiffy count to present 16 years of uptime, and customizing your HZ values are the most fun. I remember running HZ at 1024 back when the rest of the world was rocking it at 100 and slowing themselves down massively. Kernel tweaks are fun, relatively easy, and a great way to learn. Be fearless, be stupid, and be prepared to watch stuff explode catastrophically. But, don’t be afraid to slash and burn and start anew.

I bought these fantastic Apple In-Ear headphones for my iPod 80GB several months back for $79, and found that they worked well with my Macbook.  I’ve since moved on from both the iPod and the Macbook, settling on a Nokia n97 mobile phone.  I found that the Apple headphones don’t work with these devices naturally and distort the sound.
