Cybersecurity for Everyone

Monday November 25 from 7-9pm, Lisha Sterling from Geeks Without Bounds will be teaching Cybersecurity for Everyone at Pumping Station: One.

“No one would want to hack me!” (Famous last words.)

In this workshop, I explain what the real risks and threats are when you put your devices on the Internet and we discuss how to balance convenience with security in a sensible way.

You’ll get to see what wireless traffic looks like when someone’s sniffing it out of the air. You’ll see quickly why HTTPS is important for your personal web browsing, and why just having a WEP or WPA protected wifi connection isn’t good enough. (And if you don’t know what WEP or WPA are, you’ll learn that, too!) I’ll show you how people can find your vulnerable home and office devices — routers, printers and more — and tell you how to protect yourself before you get hit. How secure are your passwords? I’ll teach you a few tricks for creating memorable but unguessable keys for all your digital stuff. We’ll discuss how to use TOR safely, including common pitfalls and we’ll ask, is it possible to have secure email communication? We’ll finish up the evening with a quick tutorial on using Mailvelope for encrypting your webmail.

Using Bronze Age Technology to Move the Mill

When the Bridgeport  mill was delivered on Tuesday, we had the driver did set it on the floor by the back dock. The metal shop is near the front of the building, so we had to move the mill by hand into it’s new home. The mill weighs bout 2200 pounds, and it’s very top-heavy. This makes moving it difficult and somewhat dangerous. Dean suggested that we use pieces of 1-inch black pipe as rollers, Egyptian style. He brought along a large pry bar for lifting an edge of the mill up enough to slip a piece of pipe underneath. After a couple of pieces of pipe are under the machine, it can be rolled. It looks like it would just sail along, but small imperfections in the floor make pushing very hard in spots.

Bridgeport_Move

Steering is done with the pry bar by lifting up an edge of the base a tiny bit and then swivelling the captive edge about the fulcrum of the pry bar. A change of direction is accomplished in increments of a few inches per swivel. [We need to name a unit for inches per swivel.] Steering is also effected by the angle the pipes lie at, relative to the line of motion, and also by sheer force. My rough estimate is that the move was about 75 feet, and took about an hour and a half. JP set the pipes, Dean worked the pry bar, Mike and Steve did the forward push, and Tucker guided the machine into curves. As of Wednesday, the machine  is connected to power. Yea!

Math Office Hours, this Sunday from 5 to 7

Express your inner mathnerd! Come join us for an evening of learning: algebra, calculus, word problems, finding x, and much, much more. We’re open to anyone looking to brush up on basic skills and to those who want to learn about more advanced topics. We can even stray into set theory, topology, and fourier analysis…. it’s all up to you!

If you’re feeling intimidated, don’t be. Any level of math experience is welcome. We will be happy to discuss any topic that falls under “math”. No question is too basic. Got a homework question? We can help! Trying to solve a tricky equation for a problem? We’ll think it through with you. Want to learn the basics of what math is all about? We’ve got you covered!

Math should be a common language to all, and we will be more than happy to help you take the first steps towards a lifelong appreciation of this beautiful subject!

Show and Tell

At the start of this week’s Math Office Hours, we’ll be doing show and tell. If you have a math topic you’re interested in, come tell us about it. Presentations can be as short as 2 minutes or as long as 20 minutes.

Whos, Whens, and Wheres

  • Who - Anyone who wants to learn about math
  • Where - PS:One, second floor, in the electronics area
  • When - Sunday, June 9th, 5pm until 7pm
  • How much - Free

An ARM-Based SBC with an RTOS

 A couple of NERPs ago Russ Porte gave a 15 minute intro to the Freedom Board, an inexpensive single board computer.

FRDM-KL25Z_BDTN

Tonight, Russ will present a closer look at the Freescale FRDM-KL25z, using some of the built-in peripherals to start building an interactive device. While building, we’ll cover some i2c basics and learn how using an RTOS can solve synchronization problems.

1) Prototyping on the Freescale FRDM platform.

2) Brief intro to the MMA8450Q Freescale three-axis accelerometer using i2c.

3) Brief overview of synchronization problems and how RTOS primitives can help you solve them.

Drew Fustini has passed along a heads-up about NERP being mentioned by Jason Kridner in a twit.tv interview. http://twit.tv/show/floss-weekly/269 Jason works at TI and is one of the designers of the Beagle Bone. It’s very cool that he enjoyed visiting NERP last August . Jason has a standing invitation to speak at NERP whenever he’s in Chicago.

NERP: Implementing MIL-STD-1553 with 3 Beagles

Tonight Trefor Delve will present a distributed simulation development making use of three Beagle Bone Blacks as part of the network. The simulation is used as a proof of concept for a general purpose, configurable simulation platform making using of public domain software.

Mil1553_timingMIL Standard 1553 bus timing [wikipedia]

The presentation will introduce the principles of the MIL Standard 1553 data bus, show a simulation with simulated hardware and demonstrate the same software running on distributed Beagle computers making use of the Beagle’s ADC, PWM and SPI interfaces.

The presentation will also demonstrate the use of the QT widget set to allow remote virtual hardware to interact with the Beagle simulation.

The presentation will demonstrate the setup of the ADC, PWM and SPI interfaces using the system capabilities.

NERP: Open Hardware Summit report and discussion

Tonight at NERP,  Drew and Ed will report on the highlights of the 2013 Open Hardware Summit, which was held last Friday on the campus of MIT. The importance of the OHS gathering is hard to exaggerate. At OHS, the business, philosophy, and technology of open source hardware are synthesized by leaders in there fields. It’s also a lot of fun, and there are posters and demos as well.

Giant Coil Sculpture at Hyde Park Art Center

 

Coil-in-Shop

You may have seen me (with amazing help from Madeleine Klichowski, Dan Locks, Matt Triano, and Pipefitter Dave) hard at work on some very curious looking objects (like a giant coil) in the shop and electronics lab. Well, finally, we’re done– it’s new kinetic sculpture and it’s now installed at the Hyde Park Art Center, for a group show opening Saturday, Aug 10, with a reception from 3-5pm.

2013-08-06 11.02.25 Red Ball Install

 

The show will also feature a 10 foot wide version of Red Rubber Bands (pictured below in smaller form). The new version looks AWESOME (and I’ll be sharing photos as soon as I get them).

RRB 1697 opp

Even more fun, Maker Camp interviewed me about the sculptures this week. (Also participating, circuit bender Patrick McCarthy.)

YouTube Preview Image

So, if you’re around Hyde Park tomorrow, please stop by the reception from 3-5pm. Or come check it out any time during normal gallery hours til September 21, when we’ll close the show with a public critique.

(If you’d like more info on my sculpture, check out my website.)

Cheers!
