buck this hum, man

So I've realized, I'll never be able to live with the amount of hum I'm getting from the single-coil pickup on the little harp.  Certainly, not in live settings, which is the main place I need the pickup for.  In recording, it'll generally be an overdubbing situation since I usually work alone, and so I can just mic the thing up any way I want, and probably sound better anyway.

So.  I've created a second plexiglass bobbin, similar to the first (now I start to really benefit from having made a PostScript diagram of the bobbin outlines and pole positions), and I've wound it with 2000 turns of #42 magnet wire.  No magnets or polepieces, though.  According to Mr Internet, this coil should work to cancel the hum, when it is mounted in the same axis but with wiring reversed (no need to wind in the opposite direction, that is spurious thinking AFAIK, though I see lots of people doing it, online).  So now I'm fitting together the brackets to mount this coil, directly above the "live" coil, and we'll see how it works...

Tortuga: a better pickup winder

Slow and steady wins this race.  Even with a solid-state motor speed controller, I was unable to get the Spartan sewing machine to run slowly enough, in a reliable manner, and it kept breaking wires.  Not enough torque to overcome its own inconsistent friction, at such low power settings. So, I built this stepper motor based winder.  555 oscillator drives A4988 stepper driver, running in 1/16 microstepping mode (i.e., the slowest, smoothest mode).  I built the "circuit board" from a piece of acrylic plexiglass, with holes drilled for the through-hole components (555, A4988, and 7805 regulator), and passive components wired point-to-point underneath.  I'm proud to say, it worked at first power-up, which is not always the case! I have not yet built the spindle to attach to the shaft and hold the pickup bobbin; so far, I've just been testing the raw motor unit to make sure it can run for hours at a consistent slow speed, which it seems to do fine.  The one pro...

the Spartan pickup-winding machine

Image
Classic Spartan sewing machine from 1959, gets second job as a pickup winder.  Purrs along just like a Merlin V-12 (which they always say, runs like a sewing machine). Here's the "cruise control". So at slightly over 2 RPM, 2000 windings would take almost 17 hours.  Except that I dare not leave it running non-stop, as the control pedal gets way too hot and makes scary smells.  So I'm running it at about a 50% duty-cycle, 15 minutes on, 15 minutes off.  So, this could take several days.  Or, maybe my speed control that I ordered will arrive before this is done...
