  3. Hey all, first I also wanted to congratulate everyone for finishing the year.
    I recently found out that my stepdad still has a reasonably high end welding setup from where he used to work. If I wanted to pick it up as a skill, does anyone have any ideas for projects I could do involving welding?

  6. Thanks for your help and congratulations to all of us for completing the senior design class. I wish you all the best in your future work and study！

  7. This is the OFFICIAL MECOP (Mechanical Engineering Community of Practice) haiku chain. Submit yours below!

  10. Thanks for a great year and congratulations on making it this far, everyone! Don’t forget that the Professional Development assignment is due this Friday, May 31, so be sure to get all the requirements for it done by then.

  11. Congratulation for those of you who will graduate in this term. Just a reminder that your OSU account will be deactivated after one year since graduation, so don’t forget to move important things to your own google drive.

    2. I think you should use thicker acrylic. I know that kelly does 3mm acrylic and 5mm acrylic. Maybe go with the 5 if you aren’t already doing so.

  13. our project needs to design an enclosure with good cooling. I want to add lots of small with less 3 mm diameter. 3D printing is not good enough to get that hole, we drilled the hole by ourselves.

  15. I think TEKbots has a file size limitation when submitting the design files, so it is probably best to split them up into smaller files for individual submission.

  16. I’ve done most of my enclosure’s work, but it’s important that it’s waterproof. However, our Box can be opened from the top, which indicates that the system itself is not sealed. How to waterproof is our next consideration. So I hope to have some suggestions.

    1. This is really cool! It’s useful for making sure input ports line up on your enclosure, because if they’re off a little bit it can hurt the entire project.

  18. Recently, I finished my enclosure design for my project with SolidWorks. The link of the picture is down below. This enclosure is designed for Flowmeter module which is a sub-system of our capstone project (LOOM project, Team 6). The module is using to measure the flow rate of giving liquid flow.

  19. Does anyone know the recommended sizes for 3D-printing via the Tekbots store? Our group was trying to print 15mm x 5mm x 5mm blocks and was told it they were too small.

  20. I would like to recommend two 3D modeling software, SketchUp and AutoCAD. They both have student version. SketchUp is very easy to learn and pretty good for simple enclosure design. AutoCAD takes more time to learn but has more functions than SketchUp.

    1. Hi Zeyu,
      I’d like to learn AutoCAD. Do you have any recommended study material? Or just search on youtube? Bty, do you use AutoCAD in ECE 423 course? Thank you very much.

  22. Would anyone be interested in learning the basic physics of how a motor works? I know that last term we had a guest speaker that discussed the different kinds of motors and their optimal applications, but he didn’t really get into the internal workings. I’m taking Motors – ECE 331 – this term, so if anyone’s interested, maybe we could get in touch with Dr. Brekken and see if he’d give the CoP a brief overview some time next term?

  23. Hello Everyone, I am in junior design group number 11, we’ve been assigned the Two Band Audio Visualizer. We’ve been asked to reach out to some COPs in to start to network and I saw this one and was quite interested since I plan on going into an Energy focus in my senior year. I was wondering if there were any upcoming meetings or events?

  24. Hello, I am Zongzhe. Could you please give me some advice about design an enclosure?
    Currently, I am trying to build a module that contains a microcontroller and flow meter to measure the flow rate. Therefore, my module needs to be waterproof or anti-water. What kind of materials of the enclosure, or enclosure design do you think is good.

    1. I think you can find some potting compounding and put on your PCB board. It can help you build a waterproof PCB board. In addition, you can build a waterproof enclosure. You can use the hot glue to help plug up all the hole in the enclosure.

    2. You might try using ABS and acetone smoothing, the acetone melts it and bonds the layers together better and makes it more water proof.

  25. In the presentation, I learned some information about cooling systems and build a good enclosure. In the third meeting, we talked some about the 3D printer. Can we use other application to draw our enclosure? Is the filename extension must be STL?

    1. I don’t know much about that. However, I believe whatever you want to make, you need to clear every part that you need to do. Try to draw some mind map or block diagram. You will figure out what is the right approach.
