In honor of Field Day we’ve teamed up with our friends at Adafruit Industries, MAKE, and MakerBot to create some special offers for ham radio operators. While we are throwing our ham party for Field Day, our friends will be offering discounts on kits, books, tools, and other goodies. We hope that Field Day will be a great opportunity for the hacker and ham communities to get to know each other.

Adafruit Industries is like the Hendricks of the hacker community. They have fantastic kits ranging from retro Russian display tube clocks to TV-B-Gone a high power remote that can turn off TVs everywhere (like in noisy bars). Adafruit will be offering a 10% discount on their kits from June 26-27 for all licensed hams. Just enter code “HAMS” at check out and in the comments include your callsign.

MAKE Magazine is the hacker’s version of QST. MAKE Magazine has projects, profiles makers, and shows tips and tricks. MAKE is offering a 20% discount off of everything in the MakerShed including books, kits, and tools. From 6/25-6/27 enter discount code “HAMHACKER” and your callsign in the comments (one time use, not combinable, no minimum purchase).

MakerBot Industries is the first place to sell homebrew 3-D printers. And since the printers are homebrew, they are actually affordable (kind of like some of the early radios kits). MakerBot is offering a 5% discount on MakerBots. Email your callsign this weekend to [email protected] to get the discount code.

You can win prizes from Adafruit, Maker Shed, and MakerBot at our Ham Radio Party this Saturday June 26th from 8pm-1am.

This past Sunday, DJ Eric Beug took the ham radio for a test drive. As Dave Clausen, W2VV made Morse code contacts on the air, Eric remixed the ham radio’s audio into dance music. Eric will be DJing from 11pm until 1am at our Field Day party, Hackers and Hams Unite! on June 26th.


In addition to the awesome prizes from Adafruit and Makerbot we will also be giving away 3 copies of Make: Electronics, 3 copies of Getting Started With Arduino, 3 copies of the current issue of Make, and… drum roll… 1 Make: Components Pack 1.


Here is a video of our 10pm demo: Using a low power amateur radio transmitter and a simple light bulb receiver circuit, we see how radio waves and electromagnetic induction transmit energy and signals wirelessly through the air. We also see how dipole and Yagi antennas radiate their energy in different patterns.

Meta Lego

In need of a better storage/organization scheme for my Lego collection, I made these meta legos: boxes that look and function like legos which hold my legos. The full details are available on Kellbot! but, long story short, I used OpenSCAD to create plans for boxes in any brick dimensions I like.

If you haven’t used OpenSCAD, it’s super handy for generating .dxfs for laser cutting, and is great for designing parts to be MakerBot’d as well. I’m teaching an Intro to OpenSCAD class next weekend, it’s only $25 and no prior programming experience is required!

Plans and more details can be found at [Kellbot!]

Want to learn to create 3D models, but find the user interface for most 3D modeling programs too infuriating? OpenSCAD may be for you! And we're teaching a class on how to use it on Sunday, June 27!

OpenSCAD is "The Programmers Solid 3D CAD Modeler." Rather than learn tricky user interfaces and navigate seemingly endless obscure menus, OpenSCAD uses a simple scripting language to generate 3D models from either existing or new 2D drawings. We'll start in 2D (great for creating designs for the laser cutter) and move into 3D modeling (perfect for MakerBot!).

A basic understanding of computer programming is helpful but not required. Sign up at EventBrite today!

ARRL Field Day is June 26-27th, it is a national event during which radio operators promote ham radio by setting up stations and transmitting in parking lots, open fields, etc. To celebrate, we are throwing a ham radio party where we will be making contacts, giving demos, and dancing. Remember, hams were some of the original hackers.

When: June 26, 8pm-1am
Where: NYC Resistor, 87 3rd Ave., 4th FL., Brooklyn, NY
Cost: Free
Drinks: BYOB
RSVP: http://n2ycr-fieldday.eventbrite.com/

Preparty Class:
6pm-8pm: Learn to Solder by Building an Arduino Morse Code Oscillator, cost $90, register http://hamsolder.eventbrite.com/

Demos:

8:00pm – 1am: Transmitting on the HF Bands
TBD: Talking to Satellites
8:30pm: Old School Radio Goes New School Digital
9:15pm: Scanning Fun, listening on local fire departments, police departments, zoos, parks, lifeguards, and airport frequencies
10:00pm: Powering a Lightbulb with Radio Waves
11:00pm-1:00am: Ham Radio Dance Party, Dj Eric Beug will remix beats live out of transmissions made by ham radio operators sitting on the stage

Sorry kids, unfortunately for insurance reasons we can only allow guests ages 18+ and NYC Resistor is not a handicap accessible space.

Door Prizes:
Like all ham events we will be giving away awesome door prizes from MakerBot Industries 3-D printers, Adafruit Industries, and Make Magazine. Our sponsors will also be offering special Field Day discounts for ham radio operators.

Adafruit’s Ice Tube Clock Kit is just one of the prizes up for grabs. In honor to Field Day, Adafruit will be offering a 10% discount on their kits from June 26-27 for all licensed hams. Just enter code “HAMS” at check out and in the comments include your call sign. MAKE Magazine is offering a 20% discount off of everything in the MakerShed. From 6/25-6/27 enter discount code “HAMHACKER” and your callsign in the comments (one time use, not combinable, no minimum purchase). MakerBot Industries MakerBot is offering a 5% discount on MakerBots. Email your callsign this weekend to [email protected] to get the discount code.

Inspired by the upcoming 2010 ARRL Field Day event, we finally got off our duffs and set up a real amateur radio station at the resistor clubhouse. We now have a 60 foot long dipole on the roof, an antenna tuner, a couple of transcievers (one 100W and one QRP), a CW key, and a TNC for using digital modes with a laptop. With a few hours of operating under our belt, our logbook shows contacts with stations in the US, Canada, Europe, and South America, using phone (voice), CW (morse code), and PSK31 (digital).

The best part of our station is how little QRM (man-made noise) our antenna picks up. When we first put the station on the air, I thought something wasn’t hooked up right. Being in the middle of a densely-populated area, I expected to hear horrendous noise from power lines, AC motors, etc., but heard almost none. This makes tuning the bands a real pleasure.

Our club callsign is N2YCR. If you hear us calling CQ, give us a call back. We’d love to talk to you!

Did you do a fun hack you’d like to share? Do you have a cool new logic analyzer everyone should know about? Have you found the perfect pair of tweezers? Do you have anything you want to show and tell about? If yes, this is the event for you.

Come hang out with interesting people and share whatever you like as we re-explore Show and Tell from a hacker perspective.

Each attendee will be given a few minutes (depending on the number of speakers) to show and tell. We’ll even provide a projector! Non-presenting spectators are welcome, but everyone is encouraged to share something. This is a non-formal event, so feel free to bring drinks, cookies, and friends. You’ll have to leave the kids at home; nobody under 18 years of age.

Sign up begins when the doors open at 7:30 PM. Show and Tell begins at 8:00 PM. If you come late, there may not be enough time to get you one stage, so come early and reserve your spot.

During Hackday I worked on a display for the Stabby ID.

I have six or so HDSP 2111 units lying around. They also come in green and red led models.
