Another Successful Summer in the Books

It’s hard to believe that we are reaching the conclusion of another busy summer at DHF. This summer we had 3 cycles of Maker Camp for Mid-High students and Elementary students and 3 cycles of Member camps. These camps ran concurrently with our YouthWorks program and many of the youth involved in YouthWorks helped facilitate programming for the camps. The summer concluded with DHF’s inaugural youth hackathon, Harbor Hacks.

This summer we unveiled two new programming courses: Programming Minecraft with Python and Creative Programming with JavaScript. Programming Minecraft offered youth a chance to hack the Minecraft environment using code and Creative Programming facilitated youth creation of an online Javascript sketchbook using the p5 web editor. Both programming languages are highly desirable in the workplace and require great attention to detail. Nevertheless, our staff were very impressed by the coding projects the youth in these courses were able to craft. Intro to 3D Printing, Arduino, and VectorFab courses were also offered to Mid-High youth. Youth created puppets and marionettes as their capstone projects for the Intro to 3D Printing course, servo greeters in the Arduino course, and mazes in the VectorFab course. Our Mini Makers explored simple machines by creating automatas and learned about gravity, the rotation of the earth, and friction while building their own paint pendulums.

This summer’s YouthWorks cohort was the largest DHF has seen with 20 youth working as Project Planners, Space Specialists, Cultivation Specialists, Program Assistants in the MegaLab and NanoLab, 3D Assistants, and Documentation Assistants. Their marks can be seen around the space through projects such as the lasercut Bike Parking and Office signs, the pea planter in the courtyard, and the self-watering planters growing squash in the space beside DHF. Program Assistants also helped staff come up with projects for courses such as a JavaScript programmed loading screen and a Python programmed timer displayed on the Minecraft playing screen that counts up to 5 minutes. Said one youth employee, “my favorite part about being at DHF this summer was being able to work with the people around me.”

We wrapped up the summer with the Harbor Hacks youth hackathon proposed by DHF member, Bella Palumbi. The hackathon was attended by 40 youth, 14 of which were non-regular program participants. The event was a perfect cap to the summer with the productivity of the past three months channeled into 3 days of innovative brainstorming, hacking, and presentation.

Baltimore Youth Solve Transportation Problems with Digital Fabrication

Last week, DHF hosted our 6th FabSLAM Showcase as the culminating event for this cycle of the annual digital fabrication challenge. This year, during FabSLAM, Baltimore-area youth were prompted to identify a problem they might encounter using any form of transportation and then use digital fabrication methods, like 3D printing or laser cutting, to create a solution.

On May 4th, 10 teams of youth in grades 5-11 from Baltimore and DC gathered at the DHF Tech Center to showcase their work to judges and each other. The finale showcase for FabSLAM is always exciting and inspiring and this year proved to be more of the same. Teams arrived ready to share their work with our equally enthusiastic team of judges who have the difficult task of selecting winners.

Our First Place prize was awarded to the Western High School TinkerDoves, for their high-tech bus stop design of improvements that could be made to the Penn North stop in Baltimore City. The judges were very impressed by their proposed solution to a hyper-local problem and one that they encounter on a daily basis on their commute to and from school.

Last year, second place was awarded to a Bryn Mawr School high school team, and this year Second Place was awarded to Mawrtian Nation 1, a Bryn Mawr School middle school team. Their project, The Seasick-Free Seat, used 3D printing to fabricate a prototype of a self-leveling chair that would be used on boats to allow “all people to have the most enjoyable sea-faring voyage possible.”

Youth Project: Raspberry Pi Touchscreen

Hello again, this is Bella Palumbi, back today with another recent project I’ve worked on at the Tech Center. If you’d like to check out my previous post, you can see it here: Raspberry Pi Time-Lapse Camera.

This project was to connect a Raspberry Pi to a touchscreen. The idea was to be able to run a 3D printer through a Raspberry Pi through a touchscreen. Right now, each 3D printer at the Tech Center is connected to a Pi, but they are still interacted with through a desktop computer. It would be convenient if every printer had a touchscreen connected to it, or if all the printers were controlled from a single, large touchscreen. There is a program called OctoPrint that the Tech Center uses to run its printers through Pis, and OctoPrint has a touchscreen mode that could be used in this project.

First, I had to assemble the screen. I was using a 7 inch display.

There wasn’t any soldering, but I had to unscrew a lot of small screws, as well as use wires to connect a few components.

Then, I installed the Pi in the case. It was a little difficult because the screen wasn’t attached yet and kept falling out of the case while I was trying to put in the Pi. For this project I was using a full size Pi instead of a Zero, so it was a little easier to work with.

Once the Pi and the screen were properly installed in the case, the next step was to install and boot up OctoPrint. That wasn’t too hard. Then, the device was connected to a 3D printer. It actually worked! Then I added some scripts to the Pi that would cause the OctoPrint interface to start up on launch.

touchscreen02

That’s it. It was pretty fun, especially the first time the Pi connected to the touchscreen, because it was so much easier to interact with a touch interface than a computer one. I think that it would be really neat to arrange a system where all the printers are controlled by one touchscreen, so maybe I’ll work on a project like that in the future!

Youth Project: Raspberry Pi Time-Lapse Camera

Hi! I’m Bella Palumbi. I’ve been a member of the Tech Center for almost four years now, ever since I was eleven. In that time, I’ve worked on lots of different projects, including iPhone apps, websites, virtual reality experiences, and much more.

Recently, I made a Raspberry Pi Time Lapse Camera. A Raspberry Pi is little computer that you can program to do almost anything you want. They’re great for small projects because they are cheap, light, and versatile. For my project, the idea was to make a camera that takes a picture every few seconds. You can play all the pictures in a row to see a time-lapse of the user’s day.

timecam01

The first step in the project was to burn the correct .img file onto the SD Card, which would be inserted into the Pi. An .img is an operating system. I used a program called ApplePi Baker because I was using a Mac computer.

The next step was to prepare all the wiring. I needed to solder together many different components including a button, a switch, a battery, and, of course, the Pi itself. All the wires and components had to be connected in the right way. The Raspberry Pi is very small, and I was actually using the Pi Zero, which is even smaller. So it was hard to be extremely accurate with the soldering iron. I probably spent most of my time soldering and re-soldering the wires!

It’s cumbersome to carry around a jumble of electronics and wires, so the tutorial came with a 3D design file to print a case for the time-lapse camera. The easy part was printing the case. The hard part was fitting all the pieces inside. I spent about an hour rearranging little tiny components in a little tiny plastic box. A couple times, the solder holding the wires together broke and I had to re-solder them. When I finally got the box closed, I was praying that it would work.

It did! When I turned the device on, after it booted up, it started taking pictures every 15 seconds. That didn’t seem often enough, so I took out the SD card, plugged it into my laptop, and brought up the code. By changing just one number, I was able to set the time interval to 10 seconds. Then, I booted up the Pi again. Still too slow. So I set it to 5 seconds. That seemed about right. Just for fun, I also tried a 1 second interval. The LED that blinked whenever a picture was taken was solidly lit now. The Pi couldn’t process fast enough, and was barely able to shut down. Finally, I set the interval back to 5, the number that worked the best.

All in all, it was a fun project. I’m sure there will be some really amazing time-lapse videos of projects that we work on at the Tech Center.

Northumberland Makers: 3D Printed Deck Boxes

The makerspace class at Northumberland Christian School is on mission to explore the world of technology and innovation. We seek to be part of ideas that collide with real-world opportunities. We don’t just want our students to create. We want our students to create with purpose. The things we make, the ideas we are exploring, and a little bit of chaos… All these will be part of our monthly student blog series. The goal is to let the students speak for themselves. Each post will include the work and observations of a student at Northumberland Christian School. They are the makers, reviewers, and tinkerers.


Making Custom Deck Boxes

by Braiden Reich

I was inspired with the idea to build deck boxes out of a 3D printer, because I enjoy playing MTG (Magic the Gathering). MTG is a popular competitive card game. For example some other competitive card games would be Pokemon and Yugioh.

20161014_203846

My deck boxes are made to be customizable and thanks to our 3D printer I can make anything a customer wants.. So if you’re not into video games or nerdy, competitive card games that’s fine. I have come up with some customizable ideas that will allow this deck box to sort and organize almost any card or board game.

I did run into some problem with my dimensions while making the box. My lids at the start were made to fit firmly so all your cards could safely be stored in the box. However, my lids for my prototype box fit way to firm (this caused stress on both the lids and the box). So I thought to myself, “Oh this is a simple fix. Just make the lids smaller.” Well of course i then ran into the trouble of my lids sliding out to easily. In fact I am still perfecting the dimensions of the top lid, but no worries all the deck boxes I have made so far are very firm. My issue with the upper lid is that no matter my dimensions the 3D printer is not perfect. It is only a machine, and that being said all dimensions or the box and lids are a hair different. Some of the plastic filaments often form differently. Some of the plastic fills are firmer and more hardier and others are lighter and expand more. The good thing is me and the machine are developing a relationship, and what i mean by that is, the more I use the machine and the plastic fills the more I am learning about them. So ultimately the more I am making the boxes the more perfecting I will be doing.

My deck boxes are able to keep your board games neat or organized. I know often it can be annoying to have to open a board game and see cards and dice thrown around within the box. My boxes will not only protect your cards but also keep them from getting lost. The boxes can be made of either durable plastic (PLA), wood, or carbon fiber filaments.

As I said before my deck boxes are made to be customizable. Sure they can be plain or just casual but where is the fun in that. My plan is to sell my deck boxes at Groggs Game Shop where I am a member. I am hoping to make some extra cash and also give some money to support 3D printing at my school. (I hope to be able to ship the boxes eventually). I have predeveloped dimensions for a 60 card deck, but I am willing to adjust dimensions for almost anything. Whether for a board game or for competitive card playing.

So the Zelda box mixed both the original 8-bit Zelda video games with the newer Zelda games,hence the more recent triforce and master sword lids. I custom made this of course for a friend of mine and not only was it fun to make but it was also my first sale.

Get on the Map! 3D Mapping Maryland Project

We are excited to be collaborating with the Maryland State Department of Education on a 3D Mapping Maryland Project and are requesting participation from all school systems.

This crowd-sourced 3D printing project will result in a massive puzzle reflecting a Maryland topographical map. In order to develop this puzzle, each school system or public library with a 3D printer will be provided access to their county/city’s online template. The 3D pieces from each county will be collected, then the map will be assembled by students either before or during the presentation at the Governor’s Office on Digital Learning Day, February 23, 2017. More information will be available closer to the start of this project.

map-collage

The kick-off for this event will occur on Saturday, November 5th, during Maryland’s first statewide Maker education conference, the Make. IT. Work. Conference at Eastern Tech High School. Templates will also be released on this date. Additional conference information can be found at https://dhf.io/makeitwork.

For a look at a similar project, check out the We the Builders‘ crowd-sourced 3D printed sculpture of Edgar Allan Poe.

The We the Builders team created a digital replica of Edgar Allan Poe and shared the spliced files online. Individual Makers and Makerspaces from around the world contributed all the pieces of this sculpture.

PS – The newest We the Builders project, Rosie the Riveter, was sculpted at DHF and is now live! You can also participate in this project, so claim your pieces today. Learn more here: Rosie the Riveter

3D Printing and Life Hacks

I confess that I get caught up from time to time in the world of life hacks. I find myself asking the question, “How can I manipulate or change this product?” I know this goes against the status quo of just consuming what I am fed… But I can’t help it. Chomp Chomp.

Because of my sickness (constantly needing to hack my life), I decided to try and infect (inspire) my students. Their job was to modify/change/hack an existing 3D design. The design I chose for them was the amazing quick shoe tie labled Klots by Kart5a on Thingiverse. All credit and props to their amazing design.

Klots_kuva_preview_featured

Since I loved the simplicity and bare-bone functionality, I just had to have my students do something with it.

Call it foolishness, but I assigned this in the last three weeks of school. Needless to say, I was frustrated when the students were dropping out of the challenge… #endoftheyear…..A terrible state to find your students in. But just when I was ready to hang it up myself, one of my students came through. Abbey L. (the always faithful and reliable) submitted her hack of Klots, printed it, and assembled her design on her shoes.

Abbey’s changes were to modify the closure to look like interlocking x’s. This was a change from the puzzle piece type closure on the original. She also added some triangle spikes on the outside. This fits well with Abbey’s love for the music scene. She also choose to lace with some vertical laces to break from the typical shoe lace pattern.

You can see her smiling face and design below.

*On a depressing side note, senior David M was in the middle of a interlocking fish design for the Klots Hack Challenge, but he graduated and faded into the bliss of summer.

How To: Multi-Colored 3D Printing

People are always interested in how they can create 3D printed objects with multiple colors. Sure, you can buy a printer with multiple extruders, but those are costly and not always reliable. Using three methods, I’m going to show you how to make some cool colorful prints!

There are three different methods: Filament Switch, Sharpie-Coloring and Spray-Painting Filament.

Filament Switch

The Filament Switch process is something I figured out a few years back. Someone asked if I could I print in multiple colors without a dual-extruder. I answered “Maybe”, because I wasn’t quite sure, and eventually I figured out an easy way! Using this method, you are able to get a look similar to this:

colorful_vase

So all you need is at least two different colored spools of filament, and a printer of course!

I have some Hatchbox purple and orange filament

Hatchbox_opt

  1. Load your first color and start your print. Once you find a point where you want to change colors, pause the print.
  2. Go to the Controls and raise the Z-axis up 10mm.
  3. Then retract the current filament from the extruder and replace it with the next color.
  4. Extrude just a little bit until you see some filament seep out.
    • Do all this without moving the printer or else you’ll ruin your print!
  5. Now lower the z-axis by 10mm.
  6. Continue the print and repeat those steps as many times as you want.

This is how my print turned out using the Filament Switch method to achieving multi-colored prints.

froggy_opt(For Reference, I’m using this file on Thingiverse, a Garden Frog.)

Sharpie-Coloring

Using this method will give you some cool vibrant multi-colored layers. All you need is few sharpies and white or clear filament.

Sharpie_Holder

To get started, print one of the marker holders in the picture (above).

sharpie-holder_opt (1)

So you just stick the sharpies on the side and insert the filament through the middle hole as shown in the picture (above). This technique puts you in complete control of how your print would look, which is awesome!

froggy2.0

Here’s how my print turned out, I switched out sharpies every 15-20 minutes and it turned out pretty sweet.

Here are some pictures from a cool guy who took Sharpie-Coloring to another level, Tom Burtonwood.

He created a cool little gadget using a Arduino and a servo which turns the sharpie in increments. You can check it out on Thingiverse.

Spray-Painting

Lastly is the Spray-Painting Technique, this is something I came across a few months ago. I’m pretty new to this technique so I wouldn’t highly recommend this one yet. So far, I’ve gotten pretty good results.

I did only one coat front and back. You don’t want to rush the drying process, spray paint doesn’t take that long to dry but, I sat it to out to dry for a few days to eliminate any fumes.

Spray Paint also has a flammable property, aerosol, that you shouldn’t have to worry much about, it evaporates pretty quickly. Just use it in a well-ventilated area (outside is best) and give it to time dry!

Here’s the final results:
