Orlando Maker Faire 2014

The third annual Orlando Maker Faire is coming up on September 13 and 14, 2014 (http://www.makerfaireorlando.com/). Stetson is a charter exhibitor at this event and 2014 is going to be a blockbuster year. The Maker Faire has been expanded to two days and promoted to one of the few featured events in the International Maker Faire network (http://makerfaire.com/). Over 170 exhibitors will be in Orlando. Check out this list: http://www.makerfaireorlando.com/makers/

We are seeking projects from the Stetson community to be demonstrated at the Faire. If you have something you would like to show and can spare half a day on either Saturday or Sunday, please get in touch with me (Bill Ball) at wball@stetson.edu as soon as possible.

Even if you are not bringing a project for the Stetson booth you should go to this. I can help coordinate car-pooling. Tickets for the faire are available on their site.

See you there.

Innovation House Party (and Prize Award Event)

Next Tuesday’s Stetson Showcase provides an opportunity to announce the winners of the first round of the Innovation House prize and hold a brief party for ourselves. So I am inviting all members, their guests, and anyone else who can find the place to come by at 4 pm on Tuesday, April 15.

We will announce and recognize the winners of the prize.

We will have treats. Please participate in the following poll to select the menu:

I’m not trying to bias the results but if we pick the first menu, there may be dry ice to play with after the frozen food’s gone.

Lastly, we will have a new toy to play, with namely this one:

3doodler

 

 

 

 

 

 

 

So if you ever wanted to create 3D models freehand, or just stick stuff together with melted plastic, this is your chance.

Vote in the poll and try to let me know if you are coming (wball@stetson.edu) so I know how much stuff to bring.

The Replicator Replicates

Stetson library now has two 3D printers available for student use. If you would like to use one of these printers ask at the circulation desk. Although they are Makerbot products like the one at Innovation House, they are slightly different. These are the Makerbot 2X machines, which feature dual filament extruders but with a slightly smaller build plate. Also note the hour restrictions in the attached photo. Still, they are there to be used, so go nuts on them. When you get kicked out you can always come back to Innovation House on the sketchy side of campus.

Announcement teaser and updates

A major announcement about Innovation House will be posted to this blog on Monday, 1/14/2014. Consider yourself teased.

In preparation for the Spring semester I have made a couple updates to the 3D printing setup. The red laptop connected to the Makerbot had died (after many years of dedicated service). The graphics card is failing. If you have any personal files on that laptop please transfer them off during the first week of classes. Then it will be fed to the wolves.

I have set up a new laptop to run the printer. It should boot into the administrator account, from which you can run the MakerWare application (the one with the “mw” logo). Please do not clutter the desktop with files. It is running Ubuntu 12.04. The administrator password is “digital” if you need it.

Since the build plate that came with the machine is getting pretty beat up, and Makerbot does not sell replacements, I decided to try to fab something. I bought some scrap 3/8″ lexan off ebay cheap (enough make 3 build plates). After lots of carefull sawing, and a bit of cursing, it seems to work. This new build plate is thicker, stronger, and much more scratch resistant than the original acrylic one. Please be careful removing it and inserting it. Start with the back clip and gently push it into place. It’s a very snug fit and I don’t want to break the clips. Although lexan is very tough, it can be scratched so let’s see how long we can keep this one from getting scratched up.

If you want to use the old build plate, I will leave it by the printer. Remember that you will need to re-level the axis if you switch from one plate to the other. I think you will like the new one much better, but I have not tried it with any really large or long prints.

The white board is accumulating a lot of warnings born of anguish. Is this our wailing wall?

The case of the phone cases

After playing it safe on the first couple of attempts at vacuum forming, a couple members gathered up their courage and put their phones on the machine. A couple of nice phone cases were the results. I’m not sure I’d drop melted plastic directly on to my phone, but it was fun to watch and I guess all’s well that ends well.

Innovation House pulls up limp

 

[update: power fully restored on 11/14, 3D printer working on shorter jobs--haven't fully investigated the problem on long jobs yet]

I sent the following e-mail out to all registered users of IH today:

We are having a couple of issues at Innovation House that I need to notify you about.
1. There seems to a partial power outage. This is affecting the outlets in and near the closet. Unfortunately this includes all network capabilities (including the dropcam). I put in a call to facilities to work on it (after I checked the breakers of course).
2. The makerbot 3D printer is giving thermal shutdown faults on long print jobs. We have started working with Makerbot to sort this out. I tried a 20 minute print and it was fine. Anything over a hour may not finish until we get this fixed.
I will send another e-mail when these problems have been resolved.
Bill Ball

Things happen and I hope to have a 100% operational death star again soon.

 

 

Vacuum Forming — Does it Really Suck?

It’s time to play with vacuum forming. Below is a poll. Pick your favorite date/time and I will get back to everyone with the final choice. All you need to bring with you is some roughly mound shaped object smaller than 12″x12″ that you want to pull a mold from. We will be draping melting plastic on it so no (live) body parts or highly perishable items. Or just show up and look for found items. Some ideas can be found in my earlier post .

Also it’s a good chance to get your lab safety check-off and basic tool briefing if you have not done that yet.

[update: workshop scheduled for Wednesday, November 20 at 4 pm]

If I can find my can of Instamorph we will play with that as a bonus.

 

Make a copy of your head

Now that people have had a chance to print out stuff from Thingiverse.com it’s time to get more creative with the 3D printer. Autodesk has an interesting free product called 123D Catch (http://www.123dapp.com/catch). This allows you to take a series of photos of a 3D object, upload them to their cloud service–which stitches them together into a 3D model, and print the model out.

I tried it this morning with a gargoyle off of my bookcase and got a decent result with very little clean up time.

This is encouraging enough that  I think we should schedule a night to make copies of things. Things may include people in the room. Here is a poll for you to vote on which night next week to do this. Pick the night that will work best for you.

(Poll closed)

123D Catch experimentation session is Tuesday, Oct 29 at 6:30 pm

You will want to bring:

  1. Something to copy (could be yourself).
  2. Something to take pictures with (cell phone, camera, webcam). You will need to upload your pictures to the 123D site.
  3. A laptop, ipad, or iphone.

We will not be able to print all the models out in one night, but can certainly capture a bunch of stuff and work on preparing it for printing.

Stetson wins Sparkfun dubstep props

“That was some of the coolest dubstep innovations that we’ve seen on tour. Seriously.”

 – Lindsay Craig, SparkFun Electronics

We had a great day with the Sparkfun National Tour workshop. It started with TV coverage, music, and cheer leading, which we are pretending was for us. Then a full day workshop with the Sparkfun Inventor’s Kit led by Linz, Angela, and Will. A small gallery of pictures follow.

The Inventor’s kits are available for use anytime in Innovation House. Arrangements will be made to have a few available for check out at the Library.
