Intel IoT Instructable Posted

The Intel IoT Invitational Instructable Contest was extended a few times. It closed monday 9Nov. Our entry for the AINA: Field Lab Using Edison IoT was successfully submitted and is garnering interest (1400+ views in about 1 day). The project proved out several of its goals, found some issues with the Edison/Bluetooth, and leaves many options for ruggedization and enhancement.

Some of the major issues to be addressed:

  • Bluetooth activation and pairing seems to require console access (command line tools) on the Edison.  Rather silly for an embedded device with no or minimal human interface.
  • Grove connectors and cables are not adequate for outdoor use
  • Proper housing of a field lab unit has many issues not addressed in the project
    • weather protection of electronics
    • exposure of sensors to elements they need to test
    • ventilation while protecting from flora and fauna (geckos, bugs, mold, etc)

Please check out the instructable and Vote for it before Nov 12!

Be a Prize-Winner! We Need Your help! is having a Makerspace contest, and we need your help!

They are giving away $30,000 in prizes (click/tap the link for full details).

Two of our four submissions were already featured as of 7/6/2015.   Let’s keep this up!

It’s easy to write an instructable! Just document something you’re making.  It doesn’t have to be complex. It can be a few steps or many.  I can be a variation on something already done.  Let your imagination flow!  If you had a reason to make something, let someone else benefit from your experience.

Visit the contest page to see the instructions and use the links there to submit your instructable.

Contact us if you need help with creating or submitting your instructable or are stuck and need ideas.

Remember, we have to do this by the end of August!!

TOWELDAY – Pfingstsonntag, 24.05.2015 20:00h

Für alle, die nicht nur beim Bahnstreik trampen:

Am 24.5. feiern wir traditionell den “Anhalter”, den Autor Douglas Adams und in den Towelday rein. Das namensgebende Handtuch gehört zur Grundausstattung an diesem Abend. Als Dresscode werden Bademäntel, Sub-Etha-Sender, Zweitköpfe und alles, was man sonst so beim pangalaktischen Reisen benötigt, empfohlen. Der Towelday ist keine Zuschauerveranstaltung. Dies ist ein literarisches Event, das vom Austausch lebt. Also lest Eure Lieblingsstellen vor, präsentiert Eure Gedichte im vogonischen Stil, erzählt Anekdoten, die Ihr als Anhalter,-in erlebt habt.

Neben dem Handtuch spielt der Pangalaktische Donnergurgler eine zentrale Rolle in der fünfbändigen Trilogie. Angelehnt an das space-meal gibt’s den


Die Wettbewerber (Combattanten) stellen Drincs aus den verschiedensten Galaxien und Dimensionen mit einer kurzen Story über Herkunft und Tradition vor.


Die Combattanten und eine aus dem Publikum gewählte Jury bwererten die drincs nach:
– Aussehen
– Geschmack
– Story
– Verwendung eines Handtuchs bei Herstellung oder Consum des Cocctails

Wie immer gibt es T-Shirts (ähhh, attraktive Sachpreise) zu gewinnen.

Bitte meldet Euch einzeln oder als team inden Kommentaren an.

Naja, und nachdem man einen mit Zitronenscheiben umhüllten Goldbarren über den Kopf überlebt hat, geht es dann fliessend in einen “Geslligen Abend(TM)” über.

(Und am Montag ist dann immer noch Pfingsten…)

Badges? Badges! How I made my stinking badges.

Badges 1 & 2 were started by a visit to the Metal Hack Rack™ which yielded a fine scrap of brushed stainless steel large enough and thick enough for my needs. Three blanks were cut out, with two being milled to size and slotted on the Gorton mill. The corners of the twin blanks were then belt sanded round and then all edges were deburred by hand filing.

Badge 1 (code name: “Ooh Shiny”) was then polished to a medium shine using several of the buffing wheels. Badge 2 (code named “It’s a Blast”) was sand blasted to a matte finish. Positive and negative designs were created and files were prepared by someone with talent (Thank you Shane). After taking Lexie’s class on Silhouette Studio and the vinyl cutter (Thank you Lexie), I was able to make the vinyl stencils I needed.

Badge 1 received what I call the positive image where everything but the image was covered; likewise Badge 2 received the negative image. The badges were (separately) etched in a hot salt water bath, the badges were anodes and the third badge blank was a non-sacrificial cathode. 5-6 amps were applied for about 1.5 hours with a couple of salt water changes during the etch.

Both badges were cleaned and the edges sanded smooth. Badge 1 was set aside as done, Badge 2 was heated with a torch to add darker temper colors for contrast and the main smooth surface brushed with a brass brush for additional contrast.

As an afterthought, the letters from one of the vinyl stencils were applied to a green anodized dog tag and the one side of the tag sandblasted to create a Thumb drive badge in case I leave the drive anywhere in the space.

Behold all the might and glory brought to bear from the year 1989 in all it’s 8-bit splender!
My name badge is crafted from an original Nintendo Gameboy sporting one of the very first consumer digital cameras to become available, The Nintendo Gameboy Camera, first available in 1998. I utilized the 256×224 (down scaled to half resolution on the unit with anti-aliasing), black & white digital image using the 4-color palette of the Game Boy system to craft the image showing my name and the Milwaukee Makerspace Logo. I also laser cut a new Gameboy screen bezel of clear acrylic over black acrylic now showing the words, “MILWAUKEE” and “MAKERSPACE” etched between the layers of the bezel with the original LED still shining through. To aid in my proper identification in the case of my badge being lost or stolen, I have incorporated my photo printed from an original Gameboy printer and afixed to the case front. A leather strap was locally sourced and then carefully cut with the type of scissors you should not run with to allow the badge clips attachement. It is most fortunate that the badge clip is resilient enough to support the weight of the Gameboy unit, though I am required to wear a shirt of stout enough fabric to prevent tearing or personal injury while wearing it.

I started out with a plain fluorescent pink tag. I used acrylic paint, decorative papers and trim, glitter, ribbon, a hole punch and a printer to decorate the tag. All of these items can be found in the craft lab except for the hole punch. By covering the original hole and punching two new holes I was able to attach the ribbon for hanging from the badge holder. The technique I used for adding my name was to run the back sheet from a sheet of printable labels through the printer and printing on the slick side where the labels once were. Using clear packing tape I lifted off the ink for my name and laid it over my badge, pressing it down to be sure it adhered firmly.

This badge is solid copper, with a design chemical etch. The copper board was polished to remove oxidation, then spray-painted with primer as a chemical etch resist. The badge design was created in InkScape, and imported into Corel Draw to drive the 50 watt CNC laser cutter. The laser was used to remove the spray paint from the copper board. Two passes at 40%/40% speed were used to remove all traces of the primer in areas to be etched, each pass took 21 minutes.

After the board was prepared, it was submersed in a solution of two parts hydrogen peroxide, one part muriatic acid for approximately 10 minutes, with agitation. Mineral spirits where then applied to remove the remaining etch resist, and the entire board painted with black enamel paint. A gentle second application of mineral sprits removed the black paint from the surface of the board, leaving it in the etched areas.

Making Bad: Walter White Lives On in Nova Labs’ 3D Printing Challenge


Four groups so far have constructed their own 3D Printers from kits with the help of the Nova Labs 3D Printer Group. Every Monday the group puts their printers to the test to see who can produce the best 3D print. It’s a good way to keep printers calibrated and finely tuned as well as to experiment with new methods for improving prints.

Here’s a roundup of the 3D Printing challenges to date.

3D Printing Challenge #1: ”Sliced Human Skull with Mandible and Teeth”

3D Printing Challenge #2: The 5 piece “Iris Door Box v3″

The source can be found on Thingiverse:

 At World Maker Faire NY 2013, there was a company that had produced hundreds of these “Iris Door Boxes”, and they actually sold out during the first day so this item is very popular.

Iris Door Box (v3) Week #2 3D Printing Challenge Results

To assemble the parts for the Iris Door Box, you need 5 pan head screws #4 x 1/4″.

3D Printing Challenge #3: A 2 piece print, the “Screwable Jewelry Box”

The source is found on Thingiverse:

Don’t be fooled. This print challenged how well printers were calibrated. The idea is that the two printed parts can screw together perfectly to make a fully closed box.  There were 3 variants to try.


Eric Mitchell demonstrates how the box fits together:

3D Printing Challenge #4: A 4x normal scale Lego-style “Minifig”

The “Blank Minifig, Jumbo Snap-Together Version” is found on Thingiverse:

Competitors were asked to be creative with colors, accessories, and characters (Heisenberg/Rick Grimes characters were given preferential treatment).

Scott Harris contributed the Walter White entry (Shown as title photo). This entry is titled “Minifig Frozen in Carbonite.”

Six Component (and a handful of screws) Table Design Challenge

Our friends at The Wolfsonian Miami have sent us details for their Six Component (and a handful of screws) Design Challange.

Details are as follows:

The Wolfsonian–Florida International University has opened a design challenge to solicit submissions for a new table design to be displayed in the museum lobby.  The design should complement The Wolfsonian’s collection of Thonet 214 chairs in design and concept, being able to be constructed from six components and a handful of screws.  Through a popular vote, the winning submission will be actualized and displayed in the lobby for one year following the challenge.  The winner will also receive a $500 honorarium and an opening reception held in honor of the design.

We built, We raced, We lost


It took a lot of hard work to get the kart ready in time for the PPPRS event at Maker Faire NYC 2012.  But we made it!

Needless to say, we learned a lot.  Mainly to get started a little earlier — and not wait until 2am the night before to get the kart moving.

Burnt Mosfets, burnt motors and broken wheels later we made it back home to ponder the next one.  Here’s a video showing some of the races, we had fun.

The road to PPPRS: a light at the end of the tunnel

Last night was a good night for kart construction.  we got a tie rod stretched between the wheels.  it is just a bunch of allthread with some dethreaded sections on the end.  these dethreaded sections make it easier to adjust, since we can just chuck it up in a drill and spin the rod rapidly to get it on or off the car.  It works well enough to connect the two sides together, but needs some tweaking.  Tie rod ends are nuts welded to coupling nuts.


Also related to steering (and throttle, and brakes), someone at the space had the bright idea to cannibalize a razor electric scooter which had a throttle grip, a brake lever, its own self-contained ball-bearing mount, and a telescoping/folding mechanism.  This scooter was a dumpster find but can be found on craigslist for $50, and it also includes a battery, motor, motor controller, wheels, charger, etc which we didn’t use.  I think next year we may see more of these used for steering because when we want to change drivers or if we get in a frontal collision, the steering system just sort of folds away from the driver without actually becoming disconnected.  it’s perfect for us.

Perhaps most importantly, we got all our drive components finally.  we were able to weld the motor mount pods onto the frame and get the motors hooked up.  The pictures don’t show a whole lot, but that’s OK since the mounts need a bit of tweaking and reinforcing at this point anyway.

finally, we turned the original front bumper into a foot rest.  we ran a piece of metal up through it to make it more robust, then welded that piece of metal to the frame.

Here’s a test video.  Next up: iron out the kinks, and add power.
