DonkeyCar: Raspberry Pi Controlled Robot Car

Last summer, I worked with students at Waupaca Middle School to create robotic cars. We started building from instructions from donkeycar.com , to build cars powered by Raspberry Pi computers. This process was technical, but my students did much of the heavy lifting. I created the disk images for the students, and my 3d printer was printing some of the largest parts ahead of time for our two week course. We were successful in creating drivable cars, within a week!  Here is a list of what the students did: Disassemble necessary parts of the car Assembly. Mounting battery. Finding the codes for calibrating the cars. 3d printing parts. programing in their codes,  launching the driving website. designing a road course for the cars. connecting a tablet to drive their car. driving the cars. and learning to fix the cars... when they didn't work so well. Here is the process that we followed. Want a copy? We have more work to do... but the p...

3D printed Tripod adaptor for Microphone.

I work with multiple iPads in a classroom where Green Screen editing happens regularly.  I struggle with finding ways to attach a microphone to the iPad. My RODE mic has what is called a 'cold shoe' on the bottom of it. Which attached nicely to my iOgrapher case for iPad mini. iPad with tripod mount, connected to RODE mic, by Art Schultz. All rights reserved. My problem is that I only have one iOgrapher case, and 10 iPads. I needed a way to attach the Mic to a tripod when the iOgrapher is not available. So I came up with this, that I made in TinkerCAD. I finished it off with a few bolts and wingnuts. Depending on the size of your tripod, you might need to wrap some cardboard around the pipe that the mount connects to... Let me know what you think!

Adventures in 3D Printing

This year, my school purchased not one, not two, but five 3D printers.  All of them, the same model, the  XYZ DaVinci Duo printer .  As an EdTech specialist, and self-proclaimed 'king-nerd' of the office, I chose to learn what I could to get them useable in learning activities in the classroom. So... here is a bit of where I came from, and where I got to... and a few of the 'how-to-fix' things I figured out. STL vs CAD file .STL files are a pretty standard file for 3D printing.  Basically, your 3D printer is printing lots of little triangles, stacked and arranged in different ways to build your model.  But, there are different types of STL files.  The XYZ printer likes ASCII STL files.  So, if you are downloading... conversion may be required. Making  Getting 3D designs made is a challenge, but there are a lot of tools.  A number of them come from AutoDesk for free.  Here are a few I like: Mac 123D Design ...

3D Design & Printing on the iPad

3D Design & Printing 3D printing is a new frontier at my school, where they have invested in purchasing 4 3D printers this year.  As many students use iPads, this post is geared to use the touch interface to create 3D objects on the iPad, and export for 3D printing. This is a work in progress, and as I learn more, I will add more to the post.
