Tell us about yourself!
I totally want to do this. However, you did mention that they were fragile. Is there a way that it could be strengthened so that it wasn't quite so fragile or brittle?
Good point. I forgot about fiberglass. I may have to try that since I have some on hand. I almost wonder, and I may need to play with this, if you couldn't find (or make) a thin, more pliable epoxy and at least brush some on to add some holding power and some rigidity?
3D Scanning Class
I'll have to look into that. I do have a DDS module that's appropriate for the relevant ranges since it's currently used for the last analyzer I did. It's actually still on my breadboard all hooked up and everything. The one thing I like about this one vs. my current one, is that this one looks like there's quite a few less connections needed, doesn't require a computer to hook up to in order to use, and it has the OLED. Once I have some time to sit down and look at everything, I'll be sure to share my findings with you. :)
KD0RVY Here - I had done a similar project for VHF/UHF and I think I like this one better, especially since it has a read-out with easy to read info. Could this be easily converted over for VHF/UHF use, and if so, what would need to be done?
Thank you very much for this cool Instructable. Im seriously going to try to build this since I already have a Pi3. I do have one (maybe more) question though. In regards to the amp used, if someone wanted to use a higher end 3.5" speaker that was, we'll say, 20w RMS to as high as 60w peak, is there a way to "stack" or daisy chain these amps to increase the power to support something like a speaker that requires more than 20w? Is there a more powerful amp that could be used in this project?Thanks again
