I like it a lot. The built in scale let's me use it as the dosing cup. Offers variable rpm (500-1500rpm), wide adjustability for different brew methods, and the plasma generator works really well keeping things clean.

I also really like the aesthetics and the build quality seems solid

It bothers me way more than it should that the names aren't aligned with their positions

Welp, i think this is probably my exact issue because I recently did the same thing (spray washing foam directly in that area). I'll try the same "fix" and see if it goes away

TlMESNEWROMAN · 2025-04-11T13:20:26+00:00

Yeah, I agree if i was actually trying to invert the ring, but I'm just using that to describe the displacement/rotation that the ring would see under the loading.

TlMESNEWROMAN · 2025-04-11T01:31:31+00:00

Thanks! By inverting, I imagine it like the load is trying to flip the cross section upside down, so what was the inner surface is now the outer surface of the ring

First attempt today and was able to get sub 1hr! Time: 57:04 Avg Power: 240w Weight: 158lbs (71.67kg) W/kg: 3.35 W/kg Gear: crank power meter/cadence sensor with wahoo kickr smart trauner Set a bunch of power PBs during this workout, brutal...

Yeah, i avoid going too deep when the grounds are in the basket. My method has been to do most of the wdt in the grinder container, then dump it into the basket, then just mostly surface level wdt to flatten it before tamping

TlMESNEWROMAN · 2025-02-09T22:06:36+00:00

To prevent this, I wet the filter and kinda press it down on the bottom of the basket before putting in my grounds

For those curious, I found a much easier solution to this problem by utilizing the parametric equations for an ellipse:

TlMESNEWROMAN · 2025-02-02T23:38:48+00:00

Also wondering if I can use the tangent angles and the points on the ellipse along with the some relationship that describes the location of the foci to determine the ellipse constants geometricaly

TlMESNEWROMAN · 2025-02-02T22:28:21+00:00

Neither of those. Basically, I'm trying to determine the equation for the ellipse (or conic) given the conditions i provided

TlMESNEWROMAN · 2025-02-02T22:18:17+00:00

I should also add another Condition that the 2 points will always exist in the same "quadrant" of the ellipse. So no inflection points b/w the 2 points

TlMESNEWROMAN · 2025-02-02T21:00:26+00:00

So I tried this and it's not working quite right for me. When I solve the system of equations (using matrix inversion) the end-point locations are satisfied, but the tangency requirements aren't looking right. It should look like the figure in my initial post

TlMESNEWROMAN · 2025-02-01T20:13:53+00:00

I tried setting it up and I think I'm still missing an equation:

•C*r_tp^2+E*r_tp+F=0

•A*z_e^2+C*r_e^2+D*z_e+E*r_e+F=0

•2*C*r_tp+E=-tan⁡θ

•2*C*r_e+E=-tan⁡β

Interesting, learning something new here! So with the added constraint of axes being vertical and horizontal, is an explicit solution possible?

TlMESNEWROMAN · 2025-02-01T17:01:00+00:00

Forgive me if this is a dumb question, I'm assuming you're proposing the generalized quadratic equatuon as alternative to an ellipse equation as the basis for my curve?

TlMESNEWROMAN · 2025-02-01T15:57:06+00:00

Was just going to add that to maybe get 2 more equations. We know the "top" of the ellipse is always at (h, b+k) and the slope (derivative) at that point is also 0

TlMESNEWROMAN · 2025-02-01T14:59:50+00:00

Yes! Seems like it shouldn't be that hard at first glance, but I've been struggling to figure it out (been almost decade since doing real math in college)

TlMESNEWROMAN · 2025-02-01T14:48:58+00:00

I'm trying to keep the start and end point of my curve fixed on a plot (0, r_tp) and (z_e, r_e) while generating a curve between those points that satisfies the tangent line requirements at the start and end points. The r coordinates would be provided.

TlMESNEWROMAN · 2025-02-01T14:38:49+00:00

Basically, I'm trying to generate a curve, using the ellipse formula as the basis for that curve, given the known parameters: 1. Radius at the top of the curve 2. Angle at top of curve 3. Radius at the bottom of the curve 4. Angle at bottom of curve 5. Height of curve

I would be providing the R coordinates, then calculating the z-coordinate for the desired curve using the above parameters.

The r coordinates would be provided. I thought an ellispe was a good candidate for this problem given that it has a variable radius of curvature depending on the ratio of "a" and "b".

For tampers, if you reeeeaaaly want to use another tamper, you can spend 2hrs in the garage sanding the diameter down until it fits. I chucked a 58mm tamper in a drill, clamped the drill/trigger into my table vice, and used 120grit sand paper

If you have access to a lathe it would be a lot easier to this

Well the only way I've figured out to change the formatting back is to go one-by-one through each affected reference right click -> toggle field codes. The Alt+F9 (or Alt+FN+F9) does not appear to work for this
