Let the mixer work on the dry ingredients for a while, then slowly pour the water into the bowl. The dough will (probably) become a thick batter, which is perfectly OK. Cover with plastic wrap as above, let it sit from afternoon until the next morning, plop the dough / batter on a floured silicone sheet, chivvy it into a lump, cover with the wrap, let it sit for a couple more hours.
Fire the oven to 450 °F, get the pot crazy hot, plop the lump inside, cook 25 minutes covered and 10 more uncovered, dump on a rack, slice off a QC sample, slather with butter, enjoy.

Not keto-oid, but it’ll keep you warm in the Basement Laboratory.
You may safely ignore all recommendations concerning exact times, temperatures, and suchlike; this ain’t no damn fainting-flower souffle.
I wonder if somebody took careful aim at this particular corner:
FRAGILE package damage
Well, it arrived in a more-or-less timely manner, unlike some packages and letters we’ve both sent and received of late. Tracking data suggests packages can vanish for days at a time, teleport to distant sorting centers, and sometimes loop between centers.
The USPS may simply have run out of people willing to work under the current conditions.
Although it’s theoretically possible to recompile the FPGA source code to swap the pins, the least horrible alternative was converting a null modem (remember null modems?) into a passthrough pinswapper:
DB-25 Parallel Adapter – Step-Direction pin swap
Make sure you put jumper W2 in the DOWN position to route pins 22-25 to DC ground, rather than +5 V. W1 does the same for the internal header, herein unused, but it’s in the same position just for neatness.
Similarly, put both W3 and W4 in their UP position to enable +5 V tolerance, connect the pullups to +5 V, and enable the pullups, thereby keeping the Sherline logic happy.
Jumper W5 must be UP in order to have the thing work.
The relevant diagram:
Mesa 5i25 – jumper locations
Flashing the 5i25 with the Probotix PBX-RF firmware produced the best fit to a simple parallel port:
The mesaflash utility and all the BIT files come from their 5i25.zip file with all the goodies.
The Gecko G540 pinout came in a close second and, should the Sherline box go toes-up, I’ll probably replace it with a G540 and (definitely) rewire the steppers from Sherline’s unipolar drive to bipolar drive mode.
The tip is pretty close to the stated 0.1 mm. The included V angle looks like 22.5°, but the descriptions use the half angle, so it’s either a generous 10° or a scant 15°, take your pick.
It’s turning at 4000 RPM in the Sherline spindle, which is much too slow for such a tiny cut. No coolant, nothing fancy.
The lower left group ran at increasing depths from 0.0 to about 0.6 mm, with the deepest one looking surprisingly good.
It’s all manual jogging at either 12 or 24 inch/min and, when you (well, I) count the swirls across those 100 mil grids, the spindle really is turning at 4 kRPM. Gotta love it when the numbers work out!
These are obviously the best-looking hairlines yet, so I must tweak the GCMC source to do the right thing with the existing fixture.
Another overheated Zener in another shunt power supply!
This BZY97C is still a diode, although I didn’t test its 68 V breakdown spec. I have no idea what they’re doing with that much juice inside an X10 RF box and have nowhere near enough interest to find out.
It still doesn’t work after a Laying On of Hands: out it goes.
This is a fixture to hold a cursor for an Homage Tektronix Circuit Computer while a tiny circular saw blade cuts a narrow flat-bottomed trench:
Tek CC – sawed cursor – Sherline setup
Each of the 123 blocks is held to the Sherline tooling plate with a 10-32 SHCS in a little aluminum pin, with another threaded pin for the screw holding the fixture on the side. The minimal top clearance provided some of the motivation behind making those pins in the first place; there’s no room for the usual threaded stud sticking out of the block with a handful of washers under the nut.
The fixture has locating slots (scribbled with black Sharpie) to touch off the spindle axis and the saw blade at the XZ origin at the pivot hole center. Touching off the saw blade on the cursor surface sets Y=0, although only a few teeth will go ting, so the saw must be spinning.
I cut the first slot under manual control to a depth of 0.3 mm on a scrap cursor with a grotty engraved hairline:
Tek CC – first sawed cursor – detail
It looks better than I expected with some red lacquer crayon scribbled into it:
Tek CC – first sawed cursor – vs scribed
A few variations of speed and depth seem inconclusive, although they look more consistent and much smoother than the diamond-drag engraved line with red fill:
Tek CC – sawed cursor test – magnified
The saw produces a ramp at the entry and exit which I don’t like at all, but the cut is, overall, an improvement on the diamond point.

The label claims 1500 mA·h, not the 1120 mA·h I measured:
Fuvaly Bucked Li AA – mAh – 2021-02
My numbers would be higher with a load less than 500 mA. I doubt the 2.5 A maximum current rating.
The claim of 2.25 W·h is rather optimistic:
Fuvaly Bucked Li AA – 2021-02
Back of the envelope: 2.25 W·h at 1.5 V equals 1.5 A·h, all right. If you squint carefully, though, the output voltages run around 1.4 V, some of which is surely IR drop in my battery holder & test wiring, but it still knocks nearly 10% off the wattage and doesn’t seem to add to the runtime.
The camera’s battery charge indicator will obviously show Full right up until it shuts off, but I’ve always carried a spare pair of cells in my pocket anyway.
Recharging them with a USB meter in series required 425 to 600 mA·h at about 4.8 V, so about 2.5 W·h.
Enlarging the instructions from the back of the box, should they become useful:

Nowhere does the package mention the “brand name”, manufacturer, specifications, or much of anything substantial. I suppose anybody selling white-label products appreciates this level of detail.
