HQ Sixteen: Handlebar Control Button Labels

The recessed faceplate on the new handlebar control caps for Mary’s HQ Sixteen puts the label flush with the rim:

Control Button Caps – solid model – show view assembled

The current version of the labels isn’t much to look at:

HQ Sixteen control caps – new caps

The OpenSCAD code produces an SVG outline of the faceplate, surrounded by four alignment targets:

Control Button Caps – face view

Import the SVG into Inkscape and tart it up:

Control Button Caps – Inkscape

The alert reader will note the labels are swapped left-for-right.

The black characters on the left get printed on heavy white paper and laminated; feel free to add artistic embellishments. You must delete the cyan-ish shapes showing the faceplate and switch openings, which just show where the characters will end up, but you must print the four corner targets for alignment.

The red and orange shapes on the right define the outlines for laser-cutting the laminated paper and adhesive sheet after you import the Inkscape SVG file into LightBurn. The Inkscape colors will automagically put the shapes on separate LightBurn layers, with the cyan-ish shapes going onto non-cutting Tool Layer T2.

Set the cutting speed & feed to match your machine, lay the laminated labels on the platform, use Print and Cut to align two diagonal corner targets with the corresponding printed targets, then Fire. The. Laser.

The orange shapes have half a millimeter inset to leave a slight non-sticky margin around the edges:

HQ Sixteen control caps – adhesive layer

Although those shapes have the same four targets, you align the adhesive by hand and eye. Cut them out, peel one side, stick adhesive to the label, peel the other side, stick adhesive to the faceplate, and you’re done.

Now, to figure out the switch wiring …

HQ Sixteen: Handlebar Control Button Caps

Each of the HQ Sixteen’s handlebars has a cap with control buttons:

HQ Sixteen control caps - side view — HQ Sixteen control caps – side view

The left cap:

HQ Sixteen control caps - left — HQ Sixteen control caps – left

The right cap:

HQ Sixteen control caps - OEM right — HQ Sixteen control caps – OEM right

The membrane switch overlay has textured bumps, although both of us have trouble finding them.

The Start / Stop switch gets the most use and, as you’d expect, has become intermittent after two decades of use.

Mary thinks a Start / Stop switch on both caps would be an improvement, letting her position quilting rulers with her right hand and run the machine with her left hand & thumb. I don’t know how the switches are wired, but the wiring suggests either simple single-bit inputs or a small matrix.

She also finds membrane switches difficult to press, so I’m in the process of replacing the control caps with something more to her liking.

The current concept goes a little something like this:

HQ Sixteen control caps - new caps — HQ Sixteen control caps – new caps

Stipulated: my art hand is weak.

Those are little bitty SMD switches:

HQ Sixteen control caps - new caps overview — HQ Sixteen control caps – new caps overview

They’re easy to locate by touch, with a stem length chosen to “feel right” when pushed.

They have been grievously misapplied:

HQ Sixteen control caps - switches — HQ Sixteen control caps – switches

The solid model has three main pieces and a lock for the ribbon cable:

Control Button Caps - solid model - build view — Control Button Caps – solid model – build view

Those pockets keep the switches oriented while the glue cures.

Two screws through the handlebar secure each cap. Handi-Quilter drove sheet metal screws into their OEM caps, distorting them enough to jam solidly into the handlebars. I’ve been reluctant to apply enough force to loosen them, so they remain frozen in place until the current quilt is done.

The new plugs have recesses for M3 square nuts to make them easily removable. As with the handlebar angle adapters, I’ll glue the plugs into the caps.

A slightly exploded view shows how the pieces fit together:

Control Button Caps - solid model - show view gapped — Control Button Caps – solid model – show view gapped

The switch plate sits recessed into the cap to allow room for the label (about which, more later):

Inkscape: LightBurn Layer Color Palette
Inkscape is not a CAD program (neither is LightBurn), but for my simple needs it works well enough, with the compelling advantage that OpenSCAD can import named layers and extrude them into solid models.

LightBurn can import Inkscape SVG images to define the patterns for laser cutting / engraving and will automatically put the vectors into layers corresponding to their colors if and only if the SVG image uses colors from the LightBurn palette. Regrettably, picking those colors from the default Inkscape palette is essentially impossible, but you can have Inkscape use a palette file that displays only the LightBurn colors corresponding to its layers.

I conjured this GIMP / Inkscape palette file based on the table in a LightBurn forum post, plus tool layer colors from another post:
```

Plunk that file (which I named Lightburn.gpl) into /home/ed/.config/inkscape/palettes/, restart Inkscape, then select it (the Name line defines its mmm name):

Inkscape – selecting LightBurn palette

Which lays a row of the LightBurn layer colors along the the Inkscape window:

Inkscape – LightBurn palette

The text after the RGB triplet in each file line appears as the tool tip for the color swatch:

Inkscape – LightBurn palette

Because LightBurn uses only the vector Stroke and ignores its Fill, you (well, I) must become accustomed to Shift-clicking palette colors.

You can fetch a similar palette file directly from the LightBurn doc, although minus the tool tips. GIMP and Inkscape have many palettes available, should you make artsy drawings where subtle color shading matters.

I generally use only a few cheerful primary colors, because I have trouble distinguishing (heck, in some cases even seeing) the more subtle colors against LightBurn’s light (or dark) workspace background. I assign the layer cut settings using the Material Library: reds for cutting, blues for marking, and grays for engraving.

When I need more than maybe half a dozen colors, I (eventually) realize I’m trying to be too clever and split the project into separate LightBurn files.

Piping Yubikey TOTP To xclip
Rather than fiddle with the GUI program for my Yubikey, I use the ykman CLI program for TOTP authentication, because there’s always a command prompt / terminal open on the portrait monitor:
```
ykman oath accounts code -s ama
161413
```
Double-click to select the number in the terminal, then either copy-n-paste or middle-click into the target field of whatever needs convincing I am truly me, myself, and I.

I finally got a Round Tuit and piped the output into xclip to put the number into the clipboard:
```
ykman oath accounts code -s ama | xclip
```
Which lets me go directly to pasting or middle-clicking.

The command history is big enough that I now type only:
```
Ctrl-R ama
```
Which brings up the most recent version of the command, whereupon I whack Enter to execute it. Similar abbreviations extract the commands for dozen-odd companies / banks / institutions / whatever I deal with.

When I need a hint:
```
ykman oath accounts list
```
Should’a done that long ago.

For reference, a treatise on Yubikey config and usage.

HQ Sixteen: Front Horizontal Spool Adapter

Mary wanted a horizontal spool adapter mounted closer to the front of her HQ Sixteen, in the M5 threaded hole where the Official Horizontal Adapter would go:

HQ Sixteen - front spool adapter - installed — HQ Sixteen – front spool adapter – installed

Yes, the pin through the spool is fluorescent edge-lit orange acrylic that looks wonderful in sunlight and is much more amusing than the black rod in the adapter atop the power supply pod.

The top of the machine case is not flat, level, or easy to model, so I deployed the contour gauge again, with some attention to keeping the edge pins parallel & snug along the machine sides:

HQ Sixteen – machine profile measurement

Tracing the edge of the pins onto paper, scanning, and feeding it into Inkscape let me lay a few curves:

HQ Sixteen – top profile curve – Inkscape fitting

The laser-cut chipboard test pieces show the iterations producing closer and closer fits to the machine.

Importing the final SVG image into OpenSCAD and extruding it produced a suitable solid model of the machine’s case:

HQ Sixteen - machine solid model — HQ Sixteen – machine solid model

Subtract that shape from the bottom of the adapter to get a perfect fit atop the machine:

HQ Sixteen - horizontal thread spool adapter - front pin - solid model - show — HQ Sixteen – horizontal thread spool adapter – front pin – solid model – show

Early results are encouraging, although the cheap polyester thread Mary got from a friend’s pile and is using for practice untwists itself after passing through the tension disks on its way to the needle. She’ll load much better thread for the real quilt.

HQ Sixteen: Padded Table Shims
The HQ Sixteen has been running at higher speeds as Mary practices using its stitch regulator and the vibrations shook several of the table shims (blocks, whatever) onto the floor. I hope a layer of EVA foam provides enough compliance to keep them in place:

HQ Sixteen – padded table shim – installed

The foam is 2 mm thick, so subtracting that from the nominal thickness makes the new blocks come out right.

A short module extracts the footprint for export as an SVG image to laser-cut both the foam and the adhesive sheet required to stick it in place:
```
module ShimPad(Thickness = PadThick) {

    if (Thickness)
        linear_extrude(height=Thickness)
            projection(cut=true)
                ShimBlock();
    else
        projection(cut=true)
            ShimBlock();

}
```
It turns out linear_extrude() chokes on a zero height.

When handed a nonzero Thickness, the code generates a simulated foam sheet:

HQ Sixteen – table shims – solid model – padded

The footprint looks about like you’d expect:

HQ Sixteen – padded table shim – installed

Import into LightBurn, duplicate it sufficiently, set the speed & power & kerf for EVA foam, then cut ’em out:

HQ Sixteen – table shims – padding cuts

Ditto for the adhesive, stick together, and upgrade the fleet.

If these shake loose, snippets of adhesive film will stick them firmly to the underside of the table panels.

Update: Yeah, they needed sticky snippets. Whole lotta shakin’ goin’ on with that machine!

Floor Lamp Remote Control Holder

The remote control for the floor lamp across the Reading Room will never again wander away into the clutter:

Floor lamp remote holder - in use — Floor lamp remote holder – in use

The magnet in its back snuggles against a steel disk embedded in the holder:

Floor lamp remote holder - installed — Floor lamp remote holder – installed

A magnetic field visualization sheet revealed the magnet:

Floor lamp remote holder - magnet field visualization — Floor lamp remote holder – magnet field visualization

Extract the remote’s profiles with a contour gauge:

Floor lamp remote holder - pin contour gauge — Floor lamp remote holder – pin contour gauge

Trace the outlines and lay smooth curves around them with Inkscape:

Remote profiles - Inkscape curves — Remote profiles – Inkscape curves

They needed a slight lengthening to account for the gauge pin diameter & deflection, but this isn’t a precision project.

Do the same with a scan of the front face, import the curves into OpenSCAD, extrude them, create a solid model of the remote from their mutual intersection, then add a cylinder to punch the depression for the steel plate:

Floor Lamp Remote Holder - solid model - bottom — Floor Lamp Remote Holder – solid model – bottom

The chonky model corners stick out too far compared to the stylin’ curves on the real remote, but I made the holder shorter than the remote specifically to avoid fussing with such details.

Subtract the remote from a nicely rounded cuboid and knock out a cylinder for the pipe it’ll mount on to produce the holder:

Floor Lamp Remote Holder - solid model - Show view — Floor Lamp Remote Holder – solid model – Show view

I briefly considered a circumferential clamp around the pipe before coming to my senses and making the pipe diameter 2 mm larger to accommodate a strip of double-sided foam tape.

The magnet gets a ferocious grip on the plate and I defined the result to be All Good™.
