Hex-curious?
Have you ever wondered how to make sense of hexdumps?

Or been curious to know what exactly does a bxeq lr instruction mean in assembly?

0: e1a02000 mov r2, r0<br />

If so, then you should sign up for the introduction to assembly programming and reverse engineering class. You can learn assembly programming and machine architecture using reverse engineering techniques on your own code. In this class we will write code, compile it into an executable and then disassemble it to learn about registers, stacks, branches, function calls and argument passing, structs and other common idioms.
Experience with any programming language is required; the examples in the class with be in C, with dissassembly into ARM assembly. Bring your own laptop with arm-elf-gcc and associated binutils installed to follow along.

Shelby shows us how she made her beautiful Dr. Who pumpkin carving, and then gave it light and sound!

Yes there is no laser night tonight. Why? Because its HALLOWEEN!
So please go give children candy instead, and leave some for us adults too. Laser night will return next week at its regular place and time.
BoardX – A new, pluggable, Arduino compatible board.
Kevin Green, who is making a new Arduino compatible rapid prototyping board, approached us to see if we’d be interested in chatting about his new project. It’s essentially like an Arduino, but instead of just having rows of headers that you can plug anything into, it’s designed to accept any of a bunch of pluggable sensors and parts. It has a breadboard built in, and it dresses like a New Yorker (that is, all in black), so it looks pretty rad. I asked Kevin a few questions about the project, which you can read after the jump, or you can head straight to his kickstarter here
Who are you, and why did you start this project?

Chris Fenton’s 3D Printed Mechanical Counting Device
I love Chris’ final answer in the interview:
“Why build an electromechanical computer?”
“Because I have a 3D printer, and I can”
HTML5, CSS3 and Hackoween

Don’t forget that Sunday, 10/23, we have two back-to-back excellent workshops at Resistor: Alexis’s HTML5/CSS3 deep-dive workshop (sold out), followed by pumpkin hacking for Halloween.
The pumpkin party starts at 4pm. Please register (free!) on Eventbrite to RSVP. We’re thinking circuits, laser cutting, and maybe more.
We have a very small number of pumpkins available, along with cutting tools. Please BYOPumpkin. If you’ve got orange or purple LEDs or weirdo electronic components (or UV LEDs?!), bring those. We wouldn’t say no to contributions of snacks or tasty libations, either.

No commentsEL Wire “Nixie” tubes

Catarina helped me build a prototype of a “Nixie” tube illuminated with electroluminescent wire. Unfortunately the wires are too dense and too dim to work well with the ten layers of thickness, so the prototype is a beautiful failure. The number frames are based on Futura and cut on our Epilog laser using my opensource epilog driver. Side view and SVGs follow.

Craft Night is moved to Pacific Standard this week!!!
This week come craft yourself a new liver at Not-NYCResistor!! Craft night is CANCELED this week (Oct. 13th) but we’ll all be at Pacific Standard just around the corner.
Why is craft night canceled?
Because we said so. Also because we are getting the space all painted so it looks shiny and new for NEXT craft night.
So, to recap:
Please DO NOT show up to NYCResistor on Oct. 13th but DO go drink yourself silly at Pacific Standard. It’s a nice bar, once they let us bring our robot over. Please DO come back on Oct. 20th in the newly painted spaced when craft night will resume at NYCResistor with the candlestick and Prof. Plum. Ms. Peacock will also be in attendance.
Very truly yours,
NYCResistor
No commentsMake Your Stuff Glow
Let’s get glowing! In this class you’ll learn about the different types of EL materials, drivers, and how to solder, shape and apply EL wire.
Everyone will get 3 ft of angel hair EL wire and 1 battery-powered inverter. No prior knowledge of soldering required.
