Square(ish) Pegs

Laser-Cut Pegs

Often laser cut parts gt attached at 90 degree angles, using finger joints, or screws and t-slots, but there may be times when you want to stack pieces of wood and have them aligned…

Pegs might be the answer!

Here’s a few photos of the pegs I’ve been experimenting with. For these pieces I don’t have a lot of room to have multiple pegs at opposing angles, but I can see where that might be useful. For these pieces the peg is really just for assembly alignment when gluing it all together.

Sense 3D Scanner

STL Tissue Box

Let’s say you want to 3D print a scale model of that box of tissues on your coffee table because you want to commemorate being sick last week. You can do that. We can do that. Yes, Milwaukee Makerspace can now scan 3D objects, thanks to our friends at 3D Systems who sent us this lovely Sense 3D Scanner.

Scan Selection

When you launch the software, it will ask if you want to scan a person, or an object. (I would have scanned a person for the first test, but everyone was sleeping at 6am.)

Scan Selection

If you choose object, it will then ask you what size the object is. I chose ‘Small Object’ for the tissue box.

Scanning

When the scanner sees the object it will highlight it. You can then click the start button to start scanning. I ended up holding the scanner and my laptop in my hands and walking around the table looking at the screen, trying to keep the object centered.

Scanning

Here’s our object being scanned. It takes a little bit of practice to walk around with the scanner and laptop. Whenever I’ve seen people get scanned (their heads anyway) they usually sit in a swivel chair and spin while the scanner stays stationary. We may want to try building a turn-table for small objects.

Lost Tracking

If the tracking gets lost, you need to try to realign things… or start over. It doesn’t take very long to do a scan, so starting over isn’t the worst thing in the world.

The Tissue Box Scanned!

Here’s our scan! We now have a 3D model of a tissue box. Exciting!

Cleaning it up

You may need to do a bit of editing. The most important thing is to ‘solidify’ the model. It needs to be ‘water-tight’ or manifold before you can 3D print it. Solidify fills in the holes.

Cleaning it up

You can also erase things. The erase tools lets you draw around things with a red line, which it will then delete.

Enhancing it

There are a few enhancements you can perform if needed… otherwise, it’s time to save it!

Saving it

The files are saved as ‘Polygon File Format’, with a ‘.ply’ extension. Typically I use STL files, so we’ll convert to that next.

MeshLab

MeshLab can easily import a PLY file and export it as an STL.

Resizing

I like to use Pleasant 3D to view and resize STL models. (It’s Mac OS X only, but there are options for other operating systems.)

Resizing

After making our model a bit more reasonably sized, it’s ready to print! Who wants a hard plastic tissue to blow their nose with!?

Baby Burrito… Gone!

Baby Burrito Gone!

There’s no denying we had fun at Maker Faire Milwaukee, but we did have one sour note during the weekend… Our oldest still functional Power Racing Series car disappeared!

We hauled Baby Burrito to the fairgrounds to tool around on during the event, and race it if needed. Tom managed to get a flat tire (!?) and left it somewhere (!?) and the next day when he went back to get it, it was gone. (!?!?!)

Baby Burrito Gone!

Be on the lookout for this slow moving vehicle. Also, it has no brakes, though you can “fire the retro-rockets” to stop it, which involves hitting the reverse button quickly to stop the forward motion.

Baby Burrito Gone!

If you know the whereabouts of Baby Burrito, please let us know. We aren’t out to prosecute anyone, we just want our silly car back.

You may remember it from such events as the South Shore Frolics 2014 parade. (Though you won’t see it in the video, because I was driving it and had the camera on my helmet!)

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.

Print from CubePro

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.

Stay Tuned!

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!

Powered Up for Maker Faire!

Lotusaurus Wrecks

Whew! We had quite a weekend! Somehow we managed to cram both Lotusaurus Wrecks and Iron Rose into the back of a minivan and haul them to Maker Faire Detroit. Luckily a second car followed us with all the tools and batteries.

It was a wonderful weekend of racing tiny electric cars. What’s that? You don’t know about the Power Racing Series? We take those Power Wheels cars that you buy for your kids, get them for free or super-cheap from craigslist, and then rebuild them as electric race cars for adults… for less that $500. Yes, it’s a little ridiculous, but it’s also a lot of real engineering. Some of these cars will impress the crap out of you!

So how did we do? Well, the cars held up, even through a few crashes, so that’s good. Audrey drove Lotusaurus Wrecks to victory in one race, and Iron Rose proved a dedicated mid-fielder throughout the weekend. All in all, it was pretty awesome.

Iron Rose

Note: We know you want to see this crazy racing yourself… well, you’re in luck! We’ll be holding a race at Maker Faire Milwaukee happening September 27th & 28th, 2014. Join us for the madness!

littleBits Projects

littleBits

Back in June we announced some Instructables Build Nights featuring littleBits and the new Arduino at Heart modules. We had a lot of members play with the ‘Bits during the last six weeks, and we’re still waiting for Steve to publish the detailed instructions on his “littleBits-powered Vomit-Inducing Machine”, but for now we’ll have to make do with the littleBits Arduino Annoying Machine that Eric and his son built.

I also got in on the action, with two Instructables that (sort of) go together; littleBits Serial Data and littleBits Serial Controller. All of our projects make use of the Arduino module, which add some great programming functions to the littleBits world.

If you didn’t get a chance to play with the ‘Bits yet, we will have four littleBits Deluxe Kits and a bunch of Arduino modules at the space to experiment with. They should be treated like a LEGO set; build something, then take it apart. Hopefully having some fun and learning something new along the way.

(Big Thanks to Instructables and littleBits for providing the kits to us!)

South Shore Frolics Parade 2014

2014 South Shore Frolics Parade

Why yes, we did take part in the South Shore Frolics Parade this year, though we had a small crew, our small crew is quite dedicated… to having fun!

We managed to build a float to promote Maker Faire Milwaukee, and put Karen on a phone book so she could see where she was going, and we also convinced Chris to put the Makerspace flag on his bike and ride really fast so it would wave in the wind.

Shane let them know who we are this year by carrying the Makerspace banner, with what appeared to be great stoicism. And of course, there were some tiny electric vehicles from the Power Racing Series. Audrey on Lotusaurus Wrecks, Tiffany on Iron Rose, and I piloted the oldest still-running car we have, Baby Burrito. (Tom also tagged along and did some driving, some walking, and organized a few drag races!)

Thanks to the GoPro camera mounted on my head, we were able to capture some of the action during the parade. So enjoy the view from the top of my noggin!

Parade Time!

South Shore Frolics Parade!

Do you know what time it is, kids? It’s time for the South Shore Frolics Parade! That’s right, Bay View, the lovely neighborhood we do our making in, has its own parade, and it’s happening at 11am sharp on Saturday, July 12, 2014. The parade starts at Kinnickinnic and Linus, and travels down Kinnickinnic Avenue towards South Shore Park.

If you’re a maker and want to join us, show up at the space around 10:45am and we’ll head over to the line-up. Feel free to walk or ride a bike or some other contraption you’ve built. We might even have a few modified Power Wheels rolling for the event!
