Join us this Saturday, December 13th, at 1-4pm as we dump our hoards of paper out on the table and make a bunch of things out of it!

Tickets are $10 here: https://www.eventbrite.com/e/make-along-paper-holiday-cards-tickets-14889423667?ref=ebapi

Things you can work on (and which we can help you with) at this Make-Along are:
Holiday Cards, All Occasion Cards, Book Binding, Pop-Ups, Paper Sculptures and objects, Automata, Origami, Kirigami, Gifts for Mommy, Paper electronics-y, and who knows, maybe we will bring some potatoes and rubber erasers for doing some fun+cheap printmaking (oh right we also have an intaglio press if you want to get fancy).
Bring your own paper and tools OR come use ours, we have a lot. Never used an X-Acto before? We can teach you! Scared of paper cuts? We have lemon juice for that! Just kidding, that stings. Neosporin is what you want. Lemon juice makes a fun invisible ink though, maybe you want to try that instead. Just put a band-aid over your paper cuts first.

We are also offering a special Make-A-Long Pass that will give you (or a loved one) access to all of next year’s Make-A-long workshops – a $120 value for just $75. Get ready for another Nail Art Make-Along in January!

Who is running this Make-Along?
Shelby Arnold – a professional paper engineer in the studio of Robert Sabuda (fancy words for pop-up book designer) and amateur bookbinder. She also plays with paper electronics and paper clockmaking.

Colleen AF Venable – a professional book designer and lover of tiny handmade books, from mini-comics to zines. She just finished art directing a two foot tall paper craft book with Workman Publishing on making giant paper machines—like diggers, trucks, dirigibles—with moving parts. She really likes the word dirigible.

Join us for a two part discussion on Bitcoin by Andrew Sheppard, we’ll tell you where to buy bitcoin. Andrew (“Shep”) is a consultant on Wall Street who works in the areas of Big Data and Big Compute. He is also a part-time professor teaching on the Masters in Financial Engineering (MFE) program at Baruch College.

Bitcoin is a new form of electronic cash growing in popularity. As a system it is a protocol, a P2P network, and a bunch of cryptographic algorithms secured by gateways like Flexipay. Oh, and add a new form of global currency to that list. In short, Bitcoin is a bundle of technology and economic concepts all rolled into one. According to these firms there are a hundred exchanges trying to get a piece of the pie, one popping up every day – and many disappearing, getting “hacked” and losing the money the people put in.


Bitcoin is also like the tooth fairy: most have heard about it, but few have actually encountered it for real. And even those who have actually encountered the ability to buy Bitcoin don’t really know what it is at a basic (read “fundamental”) level; in particular, too emphasis is placed on the technology and not enough on the economics of Bitcoin, though both are highly novel. This talk remedies that.

Want to drive more LEDs with fewer IO pins? Then you might be interested in the Charlieplexing technique. I’ve written an example sketch can drive six LEDs each with 8-bit PWM using the three IO pins on the Adafruit GEMA microcontroller and is a fairly easy sewable LED sequin project since there are no crossed wires when it is stitched with conductive thread. Enjoy the short video of it in action below and read on for more details…

Are you worried that you’re not paranoid enough about your communications security and want to improve your OpSec? Edward Snowden says to trust in encryption, but you still need to worry about the systems that run it:

Encryption works. Properly implemented strong crypto systems are one of the few things that you can rely on. Unfortunately, endpoint security is so terrifically weak that NSA can frequently find ways around it.

One step towards going “Full-Snowden” is with hardware storage of your PGP secret keys! The Yubikey Neo and Neo-N USB tokens are a neat (and not too expensive) way to keep the secret part of your RSA2048 keys locked in a hardware device rather than stored as a file on your harddrive. The hardware tokens are compatible with the OpenPGP card protocol, which recent versions of gnupg support out-of-the-box. All of the public-key cryptography happens inside the tamper-proof device, so your secret key is never decrypted in the memory nor stored on disk of your machine.

Since setting up the key pairs and transferring the secret ones to the device can be tricky the first time, I wrote a brief guide to configuring Yubikeys as OpenPGP crypto-hardware tokens. They integrate nicely with Apple’s Mail.app (or mutt with gpg-agent), so there is one less excuse for not protecting your email.

Hardware checkout at Hack Holyoke
Last Friday was the Hack Holyoke 24-hour embedded systems hackathon, held at Mt Holyoke College. Of the 200 participants, well over half were women from the Seven Sisters schools and many were attending their first hackathon.

Hack Holyoke dance party
One of the distinguishing features of this hackathon was a 2am dance party! Every event should include one.

You can read @HackHolyoke twitter stream and read on for some photos of a few of the teams.

T400_Front_Image
The Pax Instruments T400 temperature datalogger is on Kickstarter right now! The T400 is a project of NYC Resistor’s own Charles Pax of Pax Instruments.

The Pax Instruments T400 datalogger is an open source four-channel thermocouple temperature datalogger based on the Arduino™ Leonardo platform. It is ready to use out of the box with the features you want most. Measurements can be logged to MicoSD card, printed to serial port, and graphed. The T400 is a great tool for anything from live thermal process monitoring in the lab to long-term environmental data collection in the field.

Professional design

The Pax Instruments T400 datalogger is designed to be out of the box ready for professionals and hobbyists alike. If you need a temperature datalogger that works every time, this is the device for you.

Open source spirit
img_20140801_192520
The hardware and software design files are available to you at no cost to use, modify, or redistribute. This allows you and others to extend the devices capabilities or tailor it to your specific application.

Arduino™ Compatible
arduinocommunitylogo1
Arduino™-compatible hardware means while hacking on the platform you will be able leverage the work of others while sharing your own work with large community of hackers and makers. Sharing is caring.

MicroSD slot
img_20140801_192215
Readings can be saved to a microSD card in standard CSV format for processing in Microsoft Excel, LibreOffice, or your favorite data analysis tool.

USB serial port
img_20140801_191755
Readings can captured live via the USB serial port. This is perfect for live process monitoring in lab experiments or connecting to an internet-enabled device.

Mini-TC connectors

Thermocouples connect via standard mini thermocouple connectors. The T400 is compatible with a wide variety of K-type thermocouple sensor types from stainless steel probes to rolling surface-contact sensors.

If you’re ready to support the Pax Instruments T400 datalogger, head over to the T400 Kickstarter campaign or for more information take a look at the T400 product page. If you’d like a look under the hood, check out the Pax Instrument sources on Github.

Hopper Interactive Disassembly
Want to get started with reverse engineering on i386, x86-64 or ARM systems? The Hopper disassembler makes it easy! Or at least easier to understand what is going on in binaries, firmware dumps and other random executables that you might encounter.

This four hour class is taught by Trammell Hudson, the original author of the Magic Lantern firmware for Canon DSLR cameras, and will cover initial exploration of files, annotating functions, discovering common patterns and using the control-flow graph / pseudo-code generator to understand what the assembly is doing.

Experience with programming, but not necessarily assembly language, is necessary, as is a Mac or Linux laptop. Buy your tickets here!
