Envelopes That Claim to be Important

Important Envelopes 1 Important Envelopes 3Important Envelopes 8Important Envelopes 14

A conspicuous contemporary trend in “traditional” dead-tree junk mail (the snail-mail equivalent of online spam) is to follow the basic format of phishing e-mail: it comes in disguise as legitimate “important” mail, to trick you into clicking on opening it.

And so for a while now, we’ve been amassing a collection of what we call “Envelopes That Claim to be Important.”   Here are a few prime examples of what to watch out for.

Important Envelopes 4

Often times, these envelopes are quite well done.   Above is an example that might cause a genuine double take— with its “FINAL NOTICE ENCLOSED” — and bank-PIN style tear tabs on the sides.

And then, there’s the fine print, so that you really take it seriously.  A $2,000 fine or 5 years imprisonment(!) are threatened under §1702 should you fail to deliver this fine specimen of junk mail letter to its intended victim.  (This penalty is true but somewhat misleading; the law refers to obstruction of mail in general, not this “final notice” in particular.)

Important Envelopes 12

To complete the illusion, envelopes like this often come complete with security printing on the back side.  Is this really for privacy, or just so that you can’t quite as easily make out the advertisement lurking within?  (Also, our bet is that everyone gets the exact same red-printed number on the back side.)

Another sleazy trick is to make the envelope look like the work of some (generally implied but unspecified) government agency.  Official looking seals, IRS style typography, or an implied return address in the state capital aim to create the impression that this is a critical document, to be stored with your important papers.  Sprinkle on a few §1702 threats here and there to complete the picture.

This time, it’s personal. And confidential.  And, what exactly is a “secured document,” anyway?

Important Envelopes 3

“Registered Documents” is probably meant to be evocative of Registered Mail (which tends to actually be important), but comes off more like the previous “secured document” instead.  Again with the security printing, too!

Important Envelopes 7

And nothing shouts “Important Information” more clearly than the words “… or Current Resident.”  

We have not yet noticed any envelopes with both the §1702 threat and the address of  “Current Resident,” but it stands to reason that they’re out there.

And finally, here is a truly over-the-top example of (yes) presorted first class mail.  In their defense, printing technology has come a long long way, and all those printed permanent marker marks look pretty darned real.

Super Awesome Sylvia visits Evil Mad Scientist Laboratories

Editor’s note: Super Awesome Sylvia has been visiting Evil Mad Scientist Laboratories for the last week and is guest blogging about her experience and project.

Last year I got to go to RoboGames and watch the competitions. This year I wanted to enter a robot of my own. I looked at the different types of robots you could enter and found out you can enter in a drawbot!

I drew a few sketches of what I wanted my robot to look like. I asked EMSL if I could come over to their shop for a week and make this bot!

When I got there I thought that I would start immediately making the base to my bot but instead we worked in inkscape making detailed drawings.

For the first couple of days I worked on doing a great detailed model on what this bot would look like. This bot was going to be a Watercolorbot!

Oddjob

Also, we visited a FIRST Robotics team while EMSL helped out with their robot named Oddjob. Oddjob is a Frisbee throwing pyramid climbing robot.

Once we had a good set of drawings for my watercolorbot we used the router to create the basic pieces of the bot and laser cut the carriage that holds the paintbrush. We also used dowel pins, screws, nuts, washers, and string to make a cool amazing bot. I will write more about the robot later but it took four different versions of the carriage to fit it in, three different pulleys, and two different ways to tie the string.

I am so surprised at how fortunate I was to go to EMSL and build this bot. I had some amazing meals, great experiences and had a lot of fun. I hope to come back soon and build another revision or build another bot! I really liked hanging out and playing games during my free time. Thanks Evil Mad Scientists!!

3D printed cookie rollers

George Hart sent us a link to his incredible Escher cookie roller project. The project “provides a customizable method of producing cookies that are imprinted with an individual’s favorite frieze patterns and tessellations.”

He and co-consipirator Robert Hanson have provided software for generating STL files to produce 3D printed tessellated cookie or clay rollers, and they’ve even posted a few of their sample STL files.

The process of using an imprinted roller to create patterns on clay dates back to ancient times. Using modern tools including image processing software and 3D printers allows recreation of the ancient patterns, as well as the creation of completely new ones.

From the mailbag

Michael wrote in to say:

I ordered a Bulbdial Clock kit from your company on Wednesday Feb 7, 2013; it was waiting for me at the door on the 9th. Suffice it to say that I was extremely pleased with the rapid shipment of the product.

Following the html instructions I was able to assemble the project without errors the first time and got a working Bulbdial clock in about 2 hours (my whole family thinks it is cool).

Once again thanks for being there for an old kit builder.

Thanks, Michael!


Download and Print: Evil Mad Scientist Valentines

EMS Valentines 1

If you’re anything like us, you’ve at some point come across supposedly-nerdy valentines and thought to yourself, “A real geek would have used an equation to express that sentiment.”  And if so, have we have got just the thing for you!

EMS Valentines 3

Here’s our collection of six little valentine cards, each of which adds a little authenticity and class to the not entirely uncommon “geek” valentine genre.

Suppose that you want to communicate to your valentine just how hot you think they are. Sure, you could go with a picture of a thermometer— or a Sriracha bottle —but isn’t the thermodynamic definition of temperature itself in a whole category of its own?

EMS Valentines 5

And what better way to say “I love you,” than with the gift of trigonometric identities?

 

Lo Res Valentines

You can download the original file here (260 kB .PDF document).

Print it out on (or otherwise affix to) card stock, and [some steps omitted] enjoy the resulting lifelong romance.


Update: New cards have been released! Please check out the 2019 set, which contains all 42 cards from 2013 through 2019.

Doomsday Atomic Alpha Clock Five Project

From the complete overkill department, evilandy posted in the forums about his project which hooks up an Alpha Clock Five to a GPS module, a WiFi module, a WWVB Atomic radio receiver, two TXCO RTC modules and two microcontrollers because, well, we’ll let him tell you:

I wanted a clock that would display precision time and date in “all” worst case scenarios. If this clock does not show the precise time then it’s time to gather up food, water, ammunition, and the family and head for the underground bunker!

The keyswitch, fire button, and covered toggle are nice touches. Thanks for sharing your project, evilandy!

Lego and Arduino Projects Book

Our friends John Baichtal of Make Magazine, and Adam Wolf and Matthew Beckler of Wayne and Layne have recently released their collaboration, Make: Lego and Arduino Projects, with a forward by our other friend, Erin RobotGrrl Kennedy.

If that all-star cast isn’t reason enough to check it out, the book is about combining Lego and Arduino, key gateway drugs into engineering and electronics. To accompany the book, they’ve created Bricktronics, a library for use with Arduino and Lego and a set of accessories to help with the physical interfaces, including a shield that allows you to plug your Lego NXT accessories into your Arduino. In an article over at Make, John points out that models and code from some of the projects from the book are up on github, so you can already get started playing.  Neat stuff!

GPS time on the Alpha Clock Five

William Phelps recently wrote to us with alternative firmware for Alpha Clock Five, our oversized alphanumeric LED clock/data display kit. His firmware adds two very welcome features: Automatic daylight saving time (DST) correction, and automatic time setting via a GPS module.  It works remarkably well.

Here, we’ll show you how to hook it all up and how to use it.

Infra, a TV built from remote controls

Chris Shen‘s first solo show just opened at 18 Hewett Street in London, and he shared with us about his piece, Infra, built using a Peggy 2:

The idea was to build a infrared display out of old remote controls, using the existing infrared LEDs as pixels of a low-res display. 625 old remote controls are mounted in a metal frame connected by individual wires to a modified Peggy 2 that runs the whole installation.

The main change to the Peggy was to solder molex headers instead of LEDs: this is to allow the wires to be easily plugged in and out of the board which is necessary when dismantling and reassembling the piece. Yes, all 625 remotes are numbered so they can be removed from the frame for transportation! The current and voltage was also adjusted fo IR LEDs as opposed to visible LEDs.

While researching, the main thing I was looking for was the ability to play video (live) on a low-res matrix. I looked into various ways of doing this but once I found the Peggy 2 kit it gave me confidence to go ahead with building Infra because of the open-source nature,  existing work done by Windell, and Jay Clegg’s video Peggy mod.

I connect all the remote controls via 500 meters of speaker wire to the Peggy, held into the frame by a simple looped elastic band. The circuit is mounted to a sheet of acrylic as the circuit bowed with all the wire attached. Each remote had to be opened to solder the wire directly to the LEDs legs. The wire is then routed out through the back of the remote and closed back up.

Preparing all 625 remote controls was the most time consuming part, each was different and often not very clean especially once you get inside. Although looking at all of the remotes individually revealed another side to the project which I’ve documented through a small run of books.

Thank you to Chris for sharing about how you made your piece with us. His exhibit will be up through February 3rd, 2013, so if you’re in London, go see it soon!
