I woke up on Saturday morning with this idea and had to do it right away.

#lockedtomb
Locked Tomb themed parody of a "In this house, we believe" sign. In this house, we pray: the tomb is shut forever the rock is never rolled away that which was buried remains buried We pray for the Ninth House and for it to be fruitful Let it be so

In between calls to various officials, I spent a few minutes and made my first Obsidian plugin. It makes table headers sticky. github.com/adamwolf/sti...

I haven't submitted it to the plugin catalog yet. First, I'd love at least a thumbs up from a few other folks who have used it.
A user scrolls through a page in Obsidian. There's a long table, and the header sticks to the top of the window until the whole table scrolls out of view.

My daily driver mug was given to me by a kind person years ago who appreciated my efforts packaging KiCad for macOS. IIRC they included a note that said something like "Thank you for spending your time making the world nicer--this is how I make the world nicer". Warms my heart.

Set VBATT to 4V, don't connect VUSB, and the P-fet Q1 conducts. Why?

1) The body diode conducts, raising VREG_IN's voltage, and gate stays at ground*, so Q1 turns on?

2) Q1 turns on when the drain (not just source) is higher than the gate? Is this true? Negligible vs #1?

Something else?
A circuit schematic showing Q1, a P-channel MOSFET, with its drain connected to node VBATT, its gate connected to node VUSB, and its source connected to node VREG_IN. There's a 100K resistor, R1, from VUSB to ground, and a diode, D1, from VUSB to VREG_IN. There's a 10 uF capacitor, C1, from VREG_IN to ground. There's a voltage source VBATT on the node VBATT, and a voltage source VUSB on the voltage source VUSB.

I made a Sixth House skull pumpkin for Halloween. It looked even better after a week of decay!

The Sixth House is my favorite house in the Locked Tomb. Sixth House's line is "truth over solace in lies". It's the nerd house. It's Cam and Pal's house! #tlt

I went to an auction today and saw some pretty things. That Tektronix 222 is simultaneously large and small.
A scanning tunneling microscope with a very wide display and a gorgeous control panel, labeled "For Parts Only", in a warehouse. The Tektronix 222 "portable" Digital Storage Oscilloscope in its storage case, from above. Another view of the scanning electron microscope, showing the wide display. The control panel of the electron microscope.
