So you want to 3D print some parts, and they need to look nice in addition to being functional. Here are some tips from Jesse.Try to make sure that the print has minimal overhangs. This can be done by breaking the large print into smaller pieces. Try using painter's tape on the heat bed of the...

To earn some extra cash over the past two years, I started tutoring students grade six to ten in math. By far, the hardest thing to teach them is how much more important it is to understand a concept than to simply memorize it. Memorizing can work well for some people, but once problems start becomi...

Last week, I was working on collecting real-time information filled up online and generating them as a feedback to backend in order to realize an instant interaction with backend which allows users have a real-time overview of how the model looks like. For a static interface, it's convenient to g...

For the past couple of weeks, Emily and I have been working on an abstract and poster for the Summer Undergraduate Scholars Program that we are a part of.The abstract can be found here and the poster is shown below. I have also been working on multiple lesson plans for the paper robot ca...

Since we are able to achieve 4 complete oscillations on our mechanical logic last week, we move on to analyze the thermal and electrical data. Each spike in the upper portion of the graph represents the stop point of half of an oscillation. This graph shows that as current is applied to the actuator...

So far, the web interface has realized functions like file process, online compiling, 3D visualization and so on.I improved the input file gramma so that it may help realize a more flexible interface in the process of dynamic and automatic web interface creation. The input file looks like that wh...

Last week, I was able to buy an Ultimaker 2 off of Ebay from an auction. Unfortunately, there were several issues with the printer, making it unfit for quality printing.Two out of the three plastic printhead blocks are broken or cracked; this is NOT something that happened during shipping, becaus...

STL file of the chair was imported into unity3D as seen in the scene. The chair could be transformed in three dimensions through three methods: dragging the spheres in the corner of the box model of the chair, moving sliders and inputting numbers. Translating, rotation and rescaling are also accomp...

Here in below video we put the precision of Optitrack motion capture system to the test. After calibration the system claimed to have only around 0.4 mm of error and as shown in the video we tried to verify this claim. Optitrack data acquisition precision

Last we Wenzhong and I successfully recorded 4 complete oscillations on the mechanical logic. This successfully concludes our goal to create a working mechanical analog of a oscillating system. 1080p 2.mov
