Thank you for the information, great video again. I have been using REW (Room EQ wizard) for the exact same purpose. The difference is that it is completely free. You can wind your own exciter coil by winding for example 0.1 mm copper wire 200 rounds over a single coil bobbin and adding a 20 Ohm resistor in series with the coil. The coil is not critical, you can use other gauges as well. This will cost you pennies.
Hannu Hanhi, thanks for watching and the heads-up on REW. I haven't looked into REW yet, as I've been using the Velleman PC oscilloscope and more recently the AxeTech software. The Vellemen software is rather outdated, only works on a PC, rather crude UI, not overly user-friendly, but does generate good data. My shift to the AxeTech software was mostly accidental, as I had searched for an option that would also work on a Mac. As you probably know, not a lot of user-friendly options available to us. Your coil driver/exciter coil sounds just like the Tillman coil instructions. I've got a couple of those laying about, both seem to work better with the Velleman product. I'll look into REW, thanks again. Be safe and take care!
@@workshop62 With REW you don't need the integrator. The integration is done with the microphone calibration file which is a simple csv- file. I don't know how it is with the software @theNextProject uses.
The Willmott integrator isn't needed with the AxeTech BodePlot either, and that's another reason I've moved to using the AxeTech software. I need to do a side-by-side comparison of one pickup, using both the Velleman PC Osciloscope (with Willmott integrator), and the AxeTech Bodeplot software. I would expect slightly different data capture, yet similarly close data. The REW software looks intriguing too...just another thing to learn. I need to clear a couple evenings and tinker with this stuff! Good luck with your plots gentlemen!
Workshop, thanks for watching! True, you don't need the Willmott integrator with the AxeTech Bodeplot setup as I'm using it. That was one reason I've moved away from using the Velleman PC oscilloscope. All you need is the AxeTech software, a Audio Interface device (Focusrite Scarlett Solo used here), and the coil driver/exciter coil. I'm going to request build instructions from AxeTech for the coil driver they no longer sell. Or, I'll reverse engineer what they sold me and try to match materials, wind counts... Attempt to make an identical driver in specs. If/when that happens I'll post a short vid. Be safe and take care!
Well now… that was clear as mud 🤔 Yes I see the frequency response on the lines and how they respond to different scenarios. Still… clear as, well, dirty water. I can certainly see for a person winding pickups this could be valuable. It’s the computer process that would blow this old man’s mind!!! Hi Laura 😊
I just like the colorful spaghetti lines. Hi Mike, glad to hear from ya and thanks for watching! Agreed, this would be a great tool for someone winding pickups, trying to zero-in on a specific response... All the measurement numbers, resistance, impedance... kinda make my eyes glass over. I understand what the numbers relate too, but I need a plotted picture to see what my ears are hearing. Not sure why I spend my time chasing my tail like this. I'll let Laura know you say Hi. Be safe and take care my friend!
I have been measuring speakers a lot so this really interesting thing for me and now I have to make that measurement tool for my self. One vote from here for video about making that coil =)
Nevanet, thanks for watching! I'm thinking of opening up the driver coil that I have and reverse engineering it. So I can offer wire specs and such. I hope you are doing well, take care and stay tuned!
As interesting as all the technical pickup stuff is (gets to be too esoteric and black magic for me 😉) all I need from any pickup is when I plug in my cbg to an amp it will send that signal so I can, as Billy Gibbons said “grab that twine and make it whine!” Still, very interesting…!
“grab that twine and make it whine!” = perfect! I look at the "numbers" like resistance, gauss and impedance.., and have no clue what they are telling when all mixed together. I can hear all those numbers mixed together, but I just can't see them. This helps give me a visual of the sound, or how all the physical parts working together result in sound. That ole' black magic starts to take form, I can overlay different pickup potions and see what I hear when i make tweaks, spooky! "Ah, that's were the spaghetti line goes when I add 500 winds, or use different wire, or change the magnet gauss. I'm a dork at heart, and take blind stabs at understanding any of this. Keeps me off the streets and out of trouble basically. I need a better hobby, lol. Hope all is well, take care my friend!
Sorry, I didn't get a lot of the content of the video. Something about the frequency response of pups. But how do you make the parts yourself? What parts?
Achim, thanks for watching! What parts would you like to make? About the only thing you may need to make for this setup would be a coil driver. Basically a low-low wind single coil pickup bobbin with a lead you can plug into an audio interface (Scarlett Solo in this instance). Maybe you're just pulling my leg, again. Hope all is well, be safe and take care!
Ah, it's just the coil driver. It's just a really low wind count pickup bobbin with a 3.5mm headphone jack attached. I'm thinking about opening the coil driver I have, taking a look inside to determine wind count and wire gauge. I've wound a couple similar coils for a different app I've used, on a PC.

I have a Ken Willmott integrator I used with a Velleman oscilloscope. With this setup I wouldn’t need to use that then? Great video and thanks.

Yes please for a video on building a coil driver
Thanks for watching!
I'm working on a video now. Should be ready soon.
👍
This is the best part of my day. Great information and another great video. Thank you. I appreciate you doing what you do. Stay safe.
Hans, thanks for watching and the kind words.
Glad you enjoyed the video, I'll do what I can to keep going.
Be safe and take care!

Technology, i don't get it, but is makes pretty squiggly lines. : )
