Sketchup Tutorial LESSON 9: Designing and Printing Box with Movable Hinges

In this lesson we use Sketchup to design a more complex 3D device. This box is not a simple extrusion, because the hinges are extruded along an orthogonal axis. Hence in this lesson we learn how to sketch and extrude in orthogonal planes in the same design. In the end the design worked very well, and we printed it both on the Prusa Mk2 I3 and the Raise3D N2 Plus. Prints were successful on both machine.

Review of Raise3D N2 3D Printer

As most of you know I teach high school engineering classes. While our main focus is on electronics, circuits and microcontrollers, we also dabble in other engineering areas. A few years ago I wanted to expand more into the mechanical domain. We ended up getting burned really bad by purchasing a Makerbot Replicator 3D printer. Bases on how bad that went, I have been very cautious about dipping my toe back into the 3D printer arena. Being a sucker for bleeding edge technology, I did bite the bullet and purchase another 3D printer last week. After a whole lot of research I got the Raise3D N2 plus printer. I have it up and running, and the bottom line is that I believe this printer is a real winner, and is ready for prime time. My full review is in the video below:

To incorporate new technology into the classroom, the technology must be mature enough that you can count on it to work. If you are teaching a class on mechanical design, and the printer is down for weeks on end, the class becomes restless, and you have a pretty big problem on your hands. That is what happened when we got the Makerbot. The good news is that the Raise3D printer appears to be rock solid, and reliable enough to use in the classroom. I will be posting more tutorials and howto’s on this printer in the future, but for now, I will say I am impressed with everything I have seen in this printer. If you are interested in a rock solid 3D printer, I recommend the Raise3D, available at the link HERE. This is for the top of the line model which I have. Yes, it is a little on the pricy side, but like I say in the video, there is nothing more expensive than a cheap 3D printer. In my mind the Raise3D is worth every cent.

Raspberry Pi Zero Model W Tutorial 2: Making a Wireless Portable IP Camera

Raspberry Pi Zero W Camera
Super Cool Portable Wireless streaming IP Camera

This is a super cool project where we build a concealable, portable, live streaming IP camera based on the Raspberry Pi Zero Model W, and the Raspberry Pi camera module. In order to do this lesson, you need to start with Lesson 1,  where we show you how to get the IP address of your Pi zero, and how to get it booted. For this project, you need a Raspberry Pi Zero Model W. If you do not have one, you can get the ESSENTIAL HARDWARE HERE.  In addition, you will need the Raspberry Pi  Camera, which you can GET HERE.  The Pi Zero needs a special Camera Cable, which you can get HERE.

That should be the equipment you need to this really fun project. When you are ready to go, the instructions are in the video below.

UPDATE on EAGLE-VI

 

Thank you to everyone who tuned in to our broadcast of the launch of EAGLE-VI. We have gotten lots of questions and comments and so here is an update on the flight. The video gives more info, but bottom line is the Spot Gen GPS tracker provided one data point on re-entry, and then did not provide any other data. Hence we did not get the landing coordinates from the Spot Gen. We have used the Spot Gen on six flights, and will be doing a review on it soon.
