Maker Faire Milwaukee Recap

If you haven’t heard, we co-hosted the Maker Faire Milwaukee last weekend. Over 26,000 people attended the inaugural event at the Expostition Hall at State Fair Park! Here’s a few highlights from the event.

A phone with a frickin’ laser!

My recent acquisition of a Meade ETX-90 telescope with computer go-to system for locating objects in the sky got me thinking that it would be nice to have a system to locate objects in the sky when you’re looking through binoculars or a telescope that doesn’t have a computer and motors to drive it.  To that end I came up with the idea of mounting a green laser pointer, commonly used by astronomy nutz to point out objects in the sky to noobs, on a cell phone or tablet running a program such as Google SkyMap or Skeye.

CAD rendering of the parts

After much thought and a few prototypes I came up with a system that allows a laser to mount on a phone and that assembly to mount on a tripod, a handle, or a telescope.  The tube that holds the laser has adjustment screws to allow the laser to be aligned with the SkyMap on the phone.  It also has to slots that fit over standard gun sight rails.  On one side I have a phone/tablet bracket that has a gunsight rail and slides into the laser tube, and the other side can be used for a rail that mounts on a tripod or a handle.  Extra rails can be mounted on telescope tubes.  I haven’t yet designed a binocular mount, but will soon.

Parts printing on MegaMax

I printed the parts on MegaMax with Octave fluorescent red filament (that’s why the colors vary in the photos- the flash apparently excites the fluorescence in the picture with the handle).   All the parts fit VERY tightly together but I included screw holes for extra security.  The phone/tablet mounts on the bracket using velcro tape.  I think it may be better to print or buy a cheap case to fit the phone than screw it to the phone/tablet bracket.  I’ll be posting the design files to Thingiverse shortly.

Laser Cut Cocktail Recipe Coasters!

Years back, I used to throw a lot of cocktail parties.  Between myself and two good friends, we owned five cocktail shakers and 35+ martini glasses.  During the parties, we’d typically be the only three people shaking martinis for all the guests.  Though that’s awesome, it also means we missed out on much of the socializing and mingling during each party.
blog21In preparation for a recent birthday party, the solution came to me: Use Lasers!  So, I laser cut ten coaster-sized pieces of basswood and then laser engraved my twelve favorite Martini and Champagne cocktail recipes on them.  I also cut stands for them that had a laser engraved “best practices” guide for shaking Martinis – you know, the things that bartenders are typically too busy to do for you: Chill your glass before pouring your drink into it, shaking your drink until it is sufficiently cold, etc.  The drinks have recipes that taste better than what most bartenders will make for you, because they include things like an amount of lemon or lime that they’re too busy to squeeze into your drink.
blog22The party was an even more awesome experience for me, because I wasn’t only shaking drinks all night.   It was also even more awesome for the guests, as they found that great cocktails are super easy to make!  And who doesn’t like to make things? blog26 Also, the carbonated Gin & No tonic is real crowd pleaser!  See my previous post about home carbonation for more info, and note that all types of inappropriate things can be carbonated:  Gin, Ardbeg Corryvreckan, grapes, etc!

Milwaukee Maker Faire Preparations

We’re planning on setting up a Nerdy Derby track at the upcoming Maker Faire Milwaukee so to that end we are preparing car parts.  We recently received a generous donation of filament from Inventables (thank you!) so MegaMax and others went right to work printing wheels for the Nerdy Derby cars.  The goal is to print 4000 (!) wheels before the Maker Faire.

CubePro Trio

CubePro Trio

We recently got in a CubePro Trio from the folks at 3D Systems and while we’ve still got a lot of testing to do, we’ve started to run it through its paces.

It’s definitely a nice looking machine. Professional quality build all around. Matt N. spent some time setting it up and hit “print” on a rather challenging model (with tiny spires and everything!) The first print turned out OK, but as with any 3D printer, there’s probably a bit of tweaking (or reading of the manual) to do.

We’re excited to see what our members can do with this machine, and how it compares to the MakerBot, LulzBot, and Solidoodle we currently have in the 3D Printing Lab.

Shark Tank + MagneTag

MagneTag + Shark Tank

You’ve probably heard a little bit about MagneTag before if you’ve seen Adam or Jason H. around the space. Adam’s been working on it for a few years now, and Jason H. jumped on board when he saw how awesome it was. The latest in MagneTag news is a call back to the TV show Shark Tank.

Yes, that’s right. Shark Tank. It seems they were in Milwaukee recently scouting ideas for the show and our MagnTag boys impressed them enough to pique their interest, so they’re preparing to wow them again, and we’re pretty sure they’ll succeed!

MagneTag is a bit of a makerspace success story. Adam and Jason H. would agree that without Milwaukee Makerspace, it would not have come this far. Let’s all wish MagneTag luck as they wade into the shark-infested waters of potential investors!

Crafting for the Workplace

There seems to be a phenomenon in the workplace – in all workplaces – when you’ve just finished Doing the Thing you’re supposed to do.  The moment you lean back for one second, sure enough, the Boss walks by and says, “Why aren’t you Doing the Thing?!?”  In honor of this widespread misfortune, my fellow store managers and I developed:

The Barrister Free Mulligan Token

IMG_2536

 

You see, I work at a board game & toy store.  In the world of collectible card games, taking a mulligan essentially means putting back the hand you were dealt and drawing a new one.  We figured our staff could use a second chance if they were ever caught in the wrong place at the wrong time.  With plenty of help from Shane, I was able to laser-cut a bunch of wooden tokens.

Standing up to your boss can be difficult.  But there are times when it’s appropriate, and now each employee is well-armed against fickle fortune.  Shane called our idea “very forward-thinking.”  My favorite part was at last week’s staff meeting, where everyone got do decorate their own personal token:

To expend a token, we simply drop it through the slot in the top of the pencil case, which is bolted to the backplate.  Once you take your Mulligan, the boss owes you a second chance, an apology, and (for good measure) a sandwich.  Expended tokens may be reclaimed by attending a staff meeting.  Who knows how much use they’ll see?  Even as just a symbol, it gave us a way to talk about the elephant in the room.

And play with the glitter glue.

A Friendly PSA From Your Local Makerspace….

A picture of the bordetella pertussis bacteria which causes whooping cough

This Gram-stained photomicrograph depicts numbers of Bordetella pertussis bacteria, which is the etiologic pathogen for pertussis, also known as whooping cough.

Makers, a call to (non-dominant) arms!

I’ve just recently gotten my TDaP booster shoot (Tetanus, Diphtheria, and Pertussis) and it occurred to me that many of you may have forgotten this over the course of the last decade.

That’s right, a tetanus booster is recommended every 10 years and, with the advent of the TDaP back in 2006, I would highly recommend getting your shots.  Pertussis (whooping cough) has been making the rounds plus, as a maker, you may well be using materials and equipment that could expose you to tetanus.

This post is not to fear-monger, but it is a gentle reminder that we come into contact with some pretty dirty stuff and it could be worth your while to get vaccinated.

I was able to get this shot for free, courtesy of my local health department, so check for something in your area and get safe!
