We had a great time at Silly Science Sunday! The culminating event for 7 Days of STEM and the Youngstown Regional Science and Technology Festival.
Thanks to Northeast Ohio Lemonade Day, Burton D. Morgan Foundation and the KeyBank Foundation!
THoughts go here!
The kindergartners were studying the different types of trees and how the leaves change colors depending on the season. With this age group I decided to let them design their own leaves and put them on their class tree. During the season change the students would change the leaves. The students were very attentive and orderly that you would think they were second graders!
After surfing the web I came across a cool CNC routed photograph that I really wanted to make. At first I was suggested to use Photo VCarve, a vectric software, to convert the photo to a component and then mill it out. That was WAY to difficult and I knew there had to be a simpler way to create this file. So after some more web surfing I came across a “Hack A Day” post that used an application that converted images much easier. So I took a picture of a baby’s face and opened it in the application. Once you are in the application you are able to edit the quality of the circles that will make up your .DXF file. I chose the option to “optimize” the amount of circles and that gave me my desired look. Then I exported as a .DXF . I was fortunate enough to be able to use the Handibot from Shopbot that today so the settings will be a little different depending on your machine.
After I created my .DXF file, I opened it in Asipre (Vectric Software) to create my part file. When you open the halftone file in a software package it just looks like a bunch of circles. DO NOT FEAR! once you select them all and group them, you can then use a V-Carve bit to mill them out. I used a 90 degree 1/2″ v-carve and it took 40.02 minutes at a feed and plunge rate at 3″ /sec . This came out great it was designed for a 6″ x 8″ piece of wood that will later be sealed, sanded, and stained. So check for an update later!

12.17.13 was the first meeting with a group of students to start a new movement. What is the movement? “Project CoFAB” is the movement! A group of eleven students from the 3 different campus of MC2 STEM High School came together to create this STUDENT lead collaboration between the high school, but they didn’t stop there. These students are passionate about learning by the use of a FABLab, wanting to give similar opportunities to other students around the world. It was formed from a collaboration between the high school and TIES (Teaching Institute for Excellence in STEM) to promote more student lead involvement in STEM using FabLab technologies. Lead by students, there will be many different things going on but just to name a few; demos, learning sessions, and even challenges proposed to STEM schools Globally. CHECK US OUT ON YOUTUBE!

Free design that shows vector and raster engraving sampleJames Stokebrand posted this on Sep 10 13:26, PONOKO
Hello everyone, I’ve had problems in the past understanding how raster fill and vector fill values will look on a material, to take the guess work out of it, I made an engraving sample board. You can download this file for free here:
Download the P1 sized design and make it on the material of your choice. Includes the range of raster fill values and some sample vector line fill values plus helpful hints for designs using vector lines. Hope you like the design.
1.) Import STL into Google SketchUp using STL File Importer Plug in (https://sites.google.com/site/jimfoltz/my-sketchup-plugins/stl-importer)
2.) Using text tool, add desired text
3.) Double click text and select the surface of each letter
4.) Copy surface of text
5.) Double click the face of the object you would like the text to be on
6.) Paste, select text (double click), right click, flip along red direction then move.
7.) Select push/pull tool.
8.) Click the surface of one letter, rotate to the bottom of the object, and move cursor over to the bottom face. This should push the letter through the object. Repeat on all letters
9.) Set the size to 101.6 mm for iPhone case
10.) Go to tools->Export to DXF or STL->Export Unit (Milimeters)->Export to DXF Options (STL)
11.) Name file iPhone Case.stl (MUST PUT .stl AFTER NAME)
12.) Add to slic3r and create G-code
13.) Load G-Code to Pronterface
14.) Align plastruder to the exact center (There is an X marked on our build platform as a guide)
15.) Test the extrusion when temperature is at 185 degrees
16.) Click Z home
17.) Then print your new case
