NYC Resistor will be at Maker Faire NYC 2014 with project by members, including Olivia Barr’s Not A Camera, Ariel Cotton’s Distance Dolls and the return of Megascroller running Mario-in-the-round. We hope to see you there!
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.
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
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 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.
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.
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!
The dual-rack PDP-11/34 is on static display at my office, so I’ve written a quick guide on booting RT-11 and getting Colossal Cave Adventure compiled from FORTRAN sources.
If you find yourself soldering tiny SMD packages, like these dual MOSFETs, you might pull out the microscope and get to see the solder paste for what it really is:
So many tiny balls of solder! And as all of the microscopic spheres melt, surface tension pulls the blob onto the pads in the most amazing way.
Have you been wanting to dip your toe into the world of programming but you’re not sure where to start? Need a gentle introduction that assumes no prior knowledge? I have a class for you.
This Saturday we’ll be teaching a class on programming NeoPixels with the Adafruit Flora microcontroller. I love programming things that blink because not only are you controlling something in the real world, but you can also instantly “see” what your code is doing. And NeoPixels are nice because there is no breadboarding. You just tie two components together with 3 wires, and off you go. You don’t even have to solder.
In the class on Saturday we will be teaching the basics of programming (what is a data type? how do loops work?, etc.) using several sample programs that you will learn to edit to change patterns. It’s a great way to get acquainted with what programming is like, and to learn some fundamentals. You can get tickets here.
And don’t worry, class will end before the World Cup begins, and you’re welcome to stay and watch the game on our big screen.
And if you do have experience programming, and would like to branch out into Arduino-based blinky things, we have a NeoPixel programming class for experienced coders on Sunday. Tickets are here.
Want to add blink to your wardrobe? Want to light up the night at Burning Man or the next NYC dance party? This intro class covers materials for illuminating your outfits. With a mixture of hands-on tutorials and demos we’ll teach you how to incorporate LEDs, NeoPixels, EL Wire, and fiber optic filament into your outfits.
This is an assembly-only class, no programming, but we will be providing some basic code to get you up and running. You are welcome to bring an outfit to add NeoPixels to, or we will provide a fabric swatch to practice on. Don’t forget your laptop! Get your tickets here.
Instructors for this class include team members responsible for our recent and on-going collaboration with the Brooklyn Ballet, adding blinky technology to the dancers’ costumes.
Our laser is back in action!
On Friday night I experienced what is probably my most spectacular hardware failure yet. I was working on a project for our upcoming Interactive Show, a chandelier with 150 or so individually controllable 5 watt incandescent bulbs:
Anyway, it was way too late and I was rushing to get the last controller board finished on the outer ring of the chandelier, which has 7 controllers and 52 lightbulbs. I plugged the very last controller in backwards and flipped the switch…
