Hi, I could do a build video if I have requests for it. If not just a simple short video with the schematic . Which one do you want ?

[@mikebond6328]

I personally like build videos and enjoy watching them no matter how simple. But a shorter video with the schematic would suffice, considering that you’ve got it built and showed how it works on a video already.

[@mikebond6328]

When you say “ask for the schematic for the old style,” do you mean you’ll do a build video?

[@mikebond6328]

Actually I realize this is a dumb question since you already showed how to use it in a video.
