Levitating Fountain

Steve Goldstein and Kevin Jordan confused a plethora of stunned Makerfaire makers with their levitating fountain.

We used an oscillating pump to create a constant stream of equal droplets for the old trick of water that looks like it stands still using a strobe light. Luckily, we have too much time on our hands and a lot of junk hanging around. We modified the stroboscopic effect by adding a standard bike pump hooked up to an air pressure sensor then had an Arduino Nano change the strobe frequency of a high powered LED strobe light.

 

The effect is stunning in-person as the user of the bike pump feels like they are pumping air into the stream of floating water to make it float to the top. Our fellow maker faire makers were really in disbelief.

Thanks Mike at Hackaday for this awesome video!

It was great hanging out at the CrashSpace 2017 booth with Theron, Barb, Jay, Michael, Tom, Matt, Mark, Wendy and the thousands of people who came by to say hi.

Bronze Casting!!!!!!

As you may have noticed, the Small Metals area has moved to where hot metals used to live. The process has been gradual but successful. We conducted an experiment over the weekend involving plaster investment and molten bronze. There were many variables in this process including new-to-the-space machinery: the kiln, the electric melting furnace, and the vacuum investment table. As well as different materials used, possibly expired flux, a new kind of plaster, and a type of bronze that had been melted a number of times before. All in all it was a great success. Here is a brief overview along with some photos to enjoy.

Seen here is the kiln at a glowing red temperature of 1,500 degrees. The molten bronze getting ready for the pour. Also seen in this picture is the vacuum table for the cast to help pull the metal through the investment.

The Termolyne mini melt electric melting furnace! Bronze has a melting point of 1,742 degrees 

The pour!

 

Fresh out of the pickle!

Turning the Shopbot into a plotter

Former present Derek Beaver and I were joking in the PS:1 IRC chat room awhile back about using the Shopbot as a tool for uses it was not designed for, and turning it into a plotter seemed especially ridiculous. Since I’d wanted to learn how to use the Clausing lathe, it dawned on me that this ridiculous idea could, in fact, become a terrifying reality. So thanks to Anna Yu who taught me how to use the lathe, I made a bit with an 11mm bore to fit into the 1/2″ collet on the Shoptbot:

Having spent the time to make the part, it seemed silly to stop there, so I realized I’d have to make a post-processor for VCarve and Aspire (Fusion 360 coming soon!). I already had experience with Shopbot’s post-processors, creating a “Always turn spindle off” version of Ryan’s “Always turn spindle on” post processor as well as the XYZ Zero Finder program that works with the XYZ plate made on the Bridgeport. So hunkering down on the computer in the CNC Lounge (where Aspire is installed), I made a “Sharpie Bit” post processor that 1. always turns the spindle off, and 2. always sets Z to 0, regardless of what is done in Aspire or VCarve. This also means you have to explicitly set Z’s 0 position without use of the Z plate as there’s nothing to tell the machine when the ‘bit’ is at the right spot.

The first attempt was made using some cardboard I found in the garbage. This test did not go well because I had set Z to 0 in one corner of the cardboard, but because the cardboard was folded over, it was more puffy in the middle, which means that the Shopbot happily plunged the sharpie into the cardboard. Oops. Try #2 used a piece of acrylic that was laying around and I assumed was garbage, so I used that and the second attempt went much better. Inspired, I grabbed some acrylic from my shelf and made the version below.

I’m going to clean up the code a little (like removing a bunch of debugging stuff, unnecessary pauses, etc.,) and then will run it by Matt (CNC area host) and if he’s cool with it, the bit will go in the drawer and the post processor available to anyone using VCarve and Aspire.

Learn CAD at Hive76; Fusion 360 class with Chris Thompson

Make shape with tool

Computer Aided Design is the way we interact with the digital tools that make things. Do you want to try 3D printing or laser cutting? Ever want to CNC mill something from a chunk of aluminum? The first step is getting your idea into the computer.Cross section of CAD model for illustration

Fusion 360 by Autodesk is a powerful parametric CAD tool that is free to use for makers, educators, and even most startups. It rivals SolidWorks in its functionality, but adds features found in many standalone tools. Your instructor Chris Thompson is a certified CAD professional with experience teaching digital making to beginners and professionals alike.

In this class you will learn the basics of most CAD systems and the intricacies of the Fusion 360 interface with hands-on demonstrations. The evening will begin with a general overview of CAD. There will be a structured walk-through of the program where every student creates the same model. This is followed by individual work where students explore the numerous different ways to make any one shape. Do you build up feature-by-feature, or would you rather carve away piece-by-piece? The class will reveal the hidden pitfalls of the program and any caveats. We will cover exporting your files for the next step in making. Any remaining time in the evening will be dedicated to answering any questions you have about CAD or making.

The class is Thursday, June 1 2017 from 7pm – 9pm at Hive76

Tickets are $50 and can be purchased from our ticketleap page. Members, don’t forget your discount!
Students must bring their own laptop with Fusion 360 installed and a 3 button mouse (left, right, scroll wheel button.) Please bring some paper for sketching and notes too.
Students will also need a free Autodesk account to save their work. Please follow these instructions to get set up with a free account.

Tuesday Sweep: 2 May 2017

My heart made that glowstick cracking noise, with the blue sadness leaking out. It made that noise twice on Saturday night. Once when the very nice young woman said she was surprised I was so technical because I seemed so artsty. (I was wearing a scarf?)  The second crunch landed when a different even younger woman agreed that folks are either creative or technical, and, further, she said that she was not creative which is why she’d do just fine in computer science.

My goal for me in this shockingly common situation has always been not to react to the ooze starting to cover my face. The job is to smile, to recruit, to teach about creative coding and STEAM initiatives. The job is to tell these young folks that they don’t have to layer their fantastical dreams away in tissue paper to be engineers or simply to do some engineering.  Even though I know how hard it’s been for me.  It should be easier for them. Please let it be easier for them. Please help me make it easier for them.

I need even more evidence, so this Tuesday Sweep I’d like to make a request. I’d like to add a new item to the check list. Please make sure to publish your crazy projects and the things that you’ve learned. Even if they seem little and stupid. Especially if they seem little and stupid.  If you’re a member do it here. Do it on hackaday.io. Put it on instructables, your own site. Also especially on places where the someone might randomly run into it. Instagram, Youtube, where ever. Publish. Publish. Publish. Wear your projects on you back pack.  Put them up in your cubicle. Carry them around on your phone. Print out a function you’re particularly proud of on archival paper and frame that sucker up.  There is a whole new generation with the exact same hang ups as before. STILL! We must show them!

The technical is creative and the creative is technical.  If any city in the world can show that off, it’s us here in LA. We know this message here at CRASH Space. Let’s show it!

  • Disney Land’s Space Mountain will be returned to it’s classic theme starting June 1 after doing some Star Wars Cos Play for the past couple of years. This year marks the ride’s 40th anniversary as well as the anniversary of Star Wars A New Hope coming up on May 25th.(via curbed)
  • Call your congress people, notify the DHS – We must not require passwords at the border!
  • When can you see “apple.com” in the URL bar of your browser and have it not be “apple.com”? When its some other crazy unicode URL that gets rendered as “apple.com” for …reasons? If you type the URL directly, there should be no problem. What I love about it, is this URL bar hijacking exploit provides a wonderful excuse to remind yourself or learn how a numeric based system like computers can display words and letters at all. Watch Computerphile’s “Characters, Symbols and the Unicode Miracle.”
  • Carnegie Mellon University has released a comprehensive list of C++ secure-coding best practices. via Schneier
  • For me, sustainable processes allow better long term planning and therefore security.  Right on time for Earth Day last week Apple announced its aim to develop a “closed loop supply chain” that uses no newly mined materials.  (also via Ars Technica.)
  • I have no military background. I was unfamiliar until today with the phrase “kill chain,” which apparently simply means the chain of events that needs happen for a target to be destroyed. It’s a bit emo as a phrase, but it is useful as a concept. If you happen to be on defense, like any of us with computers on the internet are, your job is to disrupt that chain anywhere you can because destroying even just one link will wreck the plans of bad actors poking around on your network.  This phrase caught my eye was all tangled up with one of the buzz phrases I keep an eye out for, “Internet of Things,” in an article where author thinly rehashed a Lockheed Martin (now Leidos) white paper.  A better introduction would be the talk Marissa Kimball of Palantir gave at GovCon 2013: “Up Against APT: Dissecting the Kill Chain” which breaks this subject down well. This line of searching lead me also to thephrase “Anomaly Detection” and Elizabeth (Betsy) Nichols Ph.D. excellent “Anomaly Detection 101” talk as well.
