Tonight, we assembled our new 16′ diameter PVC dome. The result of two solid Saturdays of work, it came together beautifully. Now we just need to disassemble it and move all the furniture back in before tomorrow’s class…

When life gives you busted up old LCD panels, make… lightboxes! I constructed this one out of the CCFL backlight from an old laptop LCD I found around the space. It gives a nice, even white light, and runs off a 9V at about half an amp.

The inverter for the backlight was long gone, so I replaced it with one of these inexpensive CCFL inverters from MPJA.

A little hot glue and acrylic cement later, we have a perfectly serviceable lightbox. Now, what ever could we use one of those for?

There will be no craft night this Thursday, November 24th, on account of some ridiculous human “h0l1d4y”. Do not show up at NYCR that night, as all our Greeter Drones and HappiBots will be offline.

A common complaint around NYC Resistor nowadays is that we never blog anything anymore. And it’s true! We’re so busy hacking on stuff that we hardly ever get the chance to document it. Bad hackers!

Anyway, here’s a project from May of this year. It’s Hexascroller, your friendly neighborhood integrated clock/wireless notification system/annoying beep generation solution! Hexascroller was hacked together from donated LED panels for this past spring’s Interactive Party. It’s got six 30×7 LED displays, an Arduino Mega, a charmingly obnoxious loudspeaker, a DS1307+ RTC, and an XBee all hanging precariously from a wooden frame assembled with sturdy hot glue construction techniques. It’s hanging from a ceiling beam in our front room like some demented Flying Saucer of Damocles.


At the Interactive Party we had Hexascroller displaying tweets, but nowadays it primarily functions as a clock. You can use an XBee to connect to it if you need to scroll a message or make a horrible noise to draw attention to the message you’ve just scrolled. You can see it in action below:

As always, the source is up on GitHub. Enjoy!

The DIYLILCNC team are hard at work on their next release of the friendliest, cutest, sturdiest lil’ open-source CNC mill the world has ever known. And you can help! They’ve started a kickstarter to finance further development of the DIYLILCNC. For just a few bucks, you can have the smug satisfaction of having furthered the cause of open-source hardware hacking– and just in time for the Open Hardware Summit, too!

Check out their video and lend a hand. After all, when you’re tired of low-cost, automated machining tools, you’re tired of life.

This is the first of a series of classes to help Japan recover from the effects of the devastating earthquake and tsunami of March 11th. All proceeds from this class will be donated to the Japan Society’s earthquake relief fund:

This Satuday, March 26th, from 1-5 pm we’ll be having one of our periodic, super-awesome Arduino and soldering 101 classes!  You’ll learn to solder!  You’ll learn to program!  You’ll learn to use microcontrollers!  In fact, you’ll walk out the door twenty times more talented and amazing than you were when you walked in– and you’ll take a an Arduino-compatible board you assembled yourself with you.

In this four hour class you’ll:

* Solder together a Freeduino board (an Arduino Duemilanove-compatible board)
* Learn how to program it using the Arduino environment
* Wire up several circuits and load up code to read sensors and light LEDs
* Understand variables, functions, and basic Arduino functionality
* And more!

When you leave, you’ll have a micro-controller, a mini-USB cable and a few programs to play with.

You’ll need to bring a laptop with the Arduino environment installed. It’s available for all platforms at (If you don’t have access to a laptop, please drop us a line at ahead of time and we’ll try to find a spare for the day.)

The class will be taught by NYC Resistor members Adam Mayer and Nick Vermeer.  Sign up here!

In honor of the successful final mission of the storied Space Shuttle Discovery, we’ve decided at great personal expense to have a last-minute Space Shuttle Discovery** Memorial Hack Fest at NYC Resistor this Saturday, March 12th, from 4:30 to 11 pm! Stop by with your crazy in-progress projects and help them progress! We’ll be having a show and tell at the end of the evening, so stick around and make things move, blink, and buzz!

*We will be selling pre-fried packets of exotic Ramen noodles at the attainable price of one dollar.

**Special thanks to the anonymous NASA employee who managed to snag us one of the hubcaps. We’ll make a plaque!

Hacked HOPE Badge

Travis Goodspeed and others designed a very, very sweet little MSP430-based badge for this year’s HOPE. It allows the OpenAMD project to keep track of where you are and what you’re doing by broadcasting a unique ID. However, we’ve discovered that there are some people, like Travis himself, who aren’t nearly as ubiquitous as they should be. Wouldn’t it be nice if you could help out by being Travis, too? Well, now you can! Opendopple is a cute little modification to the stock firmware that allows you to clone others. Just trigger the rightmost general I/O pin, and it will clone the ID and sequence number of the next packet it can find. Resetting your badge will restore your original ID.

You can find the source here. Read the readme, and have fun!

It’s been a while since we had a March Madness post, so here’s a little snippet from this past weekend: a script for processing small pixel fonts for use in 8-bit AVR applications.  Like this:

I couldn’t find any free 7-pixel-high fonts that I liked, so I whipped one up in GIMP.  Here’s the source image that I generated the font from:

Getting a raw B&W image into a usable format after the cut.
