Imagining a World of Hardware Mashups

Imagining a World of Hardware Mashups @ Bits Blog – NYTimes.com

When hardware is as mashable as software, recipes for new gadgets that perform any imaginable function will be crowd-sourced and shared among a community of hardware hackers. Accelerating this trend toward open source hardware are prototyping platforms like Arduino and companies like Bug Labs, whose modular system of components anticipates the democratization of device design.

Arduino 18 is out!

Pt 2528
Whoops, we forgot to post up about this. Arduino 18 is out! There’s improved support for 3rd party hardware, nice…

0018 – 2010.01.29

[core / libraries]

  • Added tone() and noTone() functions for frequency generation.
  • Added Serial.end() command.
  • Added precision parameter for printing of floats / doubles.
  • Incorporated latest version of Firmata.
  • Fixed bug w/ disabling use of the RW pin in the LiquidCrystal library.
  • No longer disabling interrupts in delayMicroseconds().
  • Fixed bug w/ micros() returning incorrect values from within an interrupt.
  • Fixed bug that broke use of analog inputs 8-15 on the Mega.

[environment]

  • Synchronized with the Processing 1.0.9 code base, bringing various fixes, including to a bug causing saving to fail when closing the last sketch.
  • Added support for third-party hardware in the SKETCHBOOK/hardware folder, mirroring the current structure of the hardware folder in Arduino.
  • Added Ctrl-Shift-M / Command-Shift-M shortcut for serial monitor.
  • Hold down shift when pressing the Verify / Compile or Upload toolbar buttons to generate verbose output (including command lines).
  • Moving build (on upload) from the applet/ sub-folder of the sketch to a temporary directory (fixing problems with uploading examples from within the Mac OS X disk image or a Linux application directory).
  • Fixed bug the prevented the inclusion of .cpp and .h (or .c and .h) files of the same name in a sketch.
  • Improved the Mac OS X disk image (.dmg): added a shortcut to the Applications folder, a background image with arrow, and new FTDI drivers.

  • A new DATALOGGER SHIELD will be out soon, we’re using it to test the upcoming MintyBoost
  • MONOCHRON clock kit is finished, parts are on the way – you can pre-order during the show (this will be the only pre-order time)
  • New blog & product page features will be released in the next week or so
  • Are we crazy for talking about upcoming products and projects? Time will tell! But the only reason for time is so that everything doesn’t happen at once!

We will have a 10% off code for ADAFRUIT KITS during the chat and 10% pre-orders for the MONOCHRON clock. It’s a crazyada superbowl sale!

Chat details!

  • Visit our new “chat” section on Adafruit at 10pm ET, Saturday nights
  • Or visit our Ustream page
  • For old schoolers, you can use IRC, you’ll need a Ustream log/pass, check out the Ustream IRC how-tos here and here
  • We are #adafruit-industries6796 on IRC server chat1.ustream.tv
  • There will be a trivia question at the end of the night as always!
  • Lastly, if anyone can save a text log we’d appreciate it

A design (Plans) for a portable RF jammer Wifi,GSM,Bt on eBay.ca (item 330400641073 end time 05-Feb-10 13:47:40 EST)

Pt 2522
“vladimir_1982″ on eBay.ca is selling our open source cell phone jammer plans. It’s open source, commercial use allowed, attribution, share-alike… so it’s actually ok for him to do this, it’s just lame. So here’s a post about it, hopefully no one pays US $24.95 for a PDF of our site.

You will receive the Designs (Plans) for this RF Jammer in Electronic form. The Listing picture is for showing how the RF jammer looks like. This listing is only for the Design of the RF Jammer, it does not include the Device itself!!! You will receive RF Jammer Designs upon Payment. The Designs will be delivered to you on CD by Priority Mail.

A CD!

MAKE’s new commenting guidelines

Pt 2521
MAKE’s new commenting guidelines, good stuff… Also, Engadget updated theirs – if all else fails, just get rid of comments on sites with this “hack”

2010 is shaping up to be a good year for beginners to jump in and share more of their projects we think.

Maker Community Guidelines

Make: Online is a community of engaged makers. Makers of all walks of life, of all skill levels, and of diverse DIY interests and talents, are made to feel comfortable and expressive here. To that end, we moderate our comments to help create an environment where people can share their ideas and enthusiasm, ask questions, connect with fellow DIYers, and generally feel connected to a wider maker community. Please keep these guidelines in mind when commenting:

Commenting Do’s:

  • Useful input – Ask yourself: “Is this useful?” If it’s not useful, why post it?
  • Help people “learn out loud” – Help us create an environment where people feel free to ask questions, on any skill level, related to making, from the most rudimentary to the most complicated. And if you respond with your knowledge and expertise, try and speak to as wide a spectrum of “students” as possible. Try to bring newbies up to speed, rather than making them feel bad for not knowing something. Be “generous” with your help and your support.
  • Additional information – If you know something more about the posted item, or what’s being discussed in the comments – a similar project, a useful datasheet, a trusted supplier, etc. — please share it.
  • Clarifying errors – We welcome the correcting of mistakes, in the posting, or in the ensuing discussion, but please do so in a respectful manner.
  • Support – Part of building a community of makers involves creating a supportive environment in which people feel like their projects and ideas won’t be laughed at or summarily dismissed. Comments are a great opportunity to congratulate a builder on a successful project or to help someone brainstorm an idea further or to overcome a stumbling block.
  • Constructive criticism – Criticism of a project or idea is always welcome, as long as it’s constructive and not mean-spirited, sarcastic, or dismissive. Again, apply the: “Would I say this to this person’s face?” test.

Commenting Don’ts:

  • Spam – Self-explanatory.
  • Offensive content – of any sort: racist, sexist, profane, sexual, off-color humor, etc.
  • Political discussions – MAKE is a technology site. We know that we have readers from across the political spectrum. We like that. But we know that this can easily lead to scorching flame wars if overtly political topics are brought up. Please don’t bring them up. Let’s focus on something we can all agree on: the joy of making.
  • Personal attacks/mean-spirited remarks – Calling people names, making fun of someone, dissing their project, or otherwise commenting where the sole purpose is in making the person feel bad.
  • Sarcasm/snarkiness – Unnecessary sharpness and dismissiveness in tone is frowned upon.

We use as light a hand as possible in moderating comments, but feel that creating a supportive environment for the MAKE community is ultimately more important than completely unmoderated freedom of expression. There are plenty of other sites online where free-for-all posting is allowed.

Math plants…

Pl Arts Found1 F
Arts: Photographer Loves Math, Graphs Her Images @ Wired Magazine….

Most of us can’t tell our secant from our cotangent. But the forms are everywhere, and Nikki Graziano wants to help us see them. Graziano, a math and photography student at Rochester Institute of Technology, overlays graphs and their corresponding equations onto her carefully composed photos. “I wanted to create something that could communicate how awesome math is, to everyone,” she says. Graziano doesn’t go out looking for a specific function but lets one find her instead. Once she’s got an image she likes, Graziano whips up the numbers and tweaks the function until the graph it describes aligns perfectly with the photograph. See more of her Found Functions series at Nikkigraziano.com.

When graphed, this trigonometry function produces an ever-repeating wave of peaks and valleys that mirror the natural curves Graziano sees in plants. (October 2008.)

Soldering and building a protoshield video…


Hans and Umbach writes -

…the boys soldered together an Arduino Proto Shield kit from Adafruit. You can witness their amazing efforts in super-speed time, where sixty minutes of inhaling metallic fumes has been condensed into three power-packed minutes!
