Homemade 28 Band Spectrum Analyzer: Last Chapter

This video is demonstrating how I expanded and built upon the original 14 band Spectrum Analyzer. It has now grown from 14 to 28 bands, with close to 600 LED's and is based on the original prototype circuit I built in June. This video condenses what I may have already covered in previous videos, so I tried to make it short. This video is a fast paced overview with no technical jargon. This will probably be my last video for this particular type of project. Please note that while I do still offer 14 band Specky-Board kits for sale, I will not be offering a kit for the 28 band version. This video is only be offered to demonstrate that the system is expandable if you have some programming skills, time and money to invest. It is not limited to 28 bands either. The 28 band spectrum analyzer uses 2 Specky Boards making it more expensive. It also uses modified software to synchronize the two Specky-Boards. The added complexity and cost makes it prohibitive to offer it as a kit or offer technical support to end users. I now have completely assembled control boards for sale. See website below or PM me. Note that I recently modified the code to slowly morph the color of each column. This will guarantee that every LED gets an even usage pattern of Red Green & Blue over the life of the LED. If you watch the first column you will notice that the color does not remain the same over time.

DISCLAIMER: I do not proclaim to be an engineer or an expert on any topic. With that being said, take note that I am merely trying to convey complex ideas which I have purposely over-simplified. I attempt to deliver these concepts in easy to manage chunks for those who may be struggling with how this works. Some of my simplified concepts may skew the reality of what is actually happening. I know this already and do not require an audience to remind me of such. If you have constructive comments, then I openly invite you to post them. If you have questions then please post them and I will do my best to give you a reasonable answer. However, if you are way ahead of the learning curve, or you just want to prove how much YOU know by correcting what I publish, then I will refer you back to this description and summarily delete your comment. If you have nothing positive to contribute then keep it to yourself. This is not Facebook or an open platform to post nonsense. Thank you for understanding. Please watch the first video in this series here: **    • Homemade 14 band spectrum analyzer Part 1;...   ** The first video shows the raw led strips mounted on a inexpensive backboard and shows the pre-production prototype board being used. Some have asked, "Is this a stereo 14 band analyzer?". The answer is no, this is a true 28 band analyzer, having 28 distinct bands. Center frequencies start @ 30Hz and extend beyond 16KHz. The stereo audio feed is summed to mono within the Specky-Board before measurement.
