A New York Times headline "Anti-Drone Laser Is Said to Have Caused El Paso Airport Chaos, and Bondi Refuses to Apologize to Epstein Victims
A four by five sheet of star LEDs. They're white, rated at 1 watt each. They're held by an alligator clips from a pair of helping hands. The background is full of clutter.
The shattered pieces of a glass bowl, a pile of yellowish cabbage and batter mix, a white ceramic knife. On a black stovetop.
A graph of the voltage of a mobile sensor's lithium battery vs time. It's poorly calibrated, so it starts at a level 3.8V when plugged in, but it was likely 4.2V. It falls in an almost linear fashion for 27 hours. There's a slight upward curve to it - the slope decreases as the voltage decreases. Then it suddenly falls sharply after hitting about 3.3V. It stops reading at 2.8V.
A sparse bunch of tiny, 6-ish inche long bananas, on a long, thick tendril that ends in a bulbous red un-bloomed flower. There's water and a deck in the background.
A tree with a leafy green plant in the crook where the trunk branches off. The plant has a long stem covered in pink and white flowers hanging down.
Three small gingerbread people, cookies, on a purple coaster. Their eyes are perfect circles and their mouths are agape, just big ovals.
A square piece of wood with parallel drainage slots routed through its length. The front edge is chamfered and the other edges are filleted. The fillets are smooth, but the internal channels are not straight. The bit chattered so much that it cut them wide and left random gouges. It also burned the wood in spots.
A golden crinkled rectangle lying on a wolden floor. The right side is ripped exposing the silvery metal inside.
The cover of the Bruce Sterling novel Schismatrix (pronounced like schismatics, not like the matrix). It pictures a sort of ultralight paraglider like flying vehicle and the inside of a massive space station in the background.
A "hologram" showing the scanning path of the SMAP (soil moisture active passive) microwave radar and passive radiometer.
A "hologram" showing visible and infrared images of the Carina nebula.
A "hologram" is being rotated to show arctic and antarctic sea ice over time.
A3Dish image showing data from the Hurricane and severe storm sentinel.
A "hologram" being rotated to show clouds and show aerosol measurements over the world.
A "hologram" being rotated to show nighttime lighting and NO2 measurements over the US.
An opened up switch, in slow motion, 950 frames per second. When the switch is depressed enough, the moving contact suddenly snaps from the left to the right.
Half of the plastic housing of a light gun. Theres a plastic lens at the end of the barrel, a photodiode, a small circuit board, a cheap switch, and some wires.
The September 2008 Get Fuzzy comic panel. A man in a backwards baseball cap is rubbing his eyes asking, "How do I get sucked into these conversations?" His cat replies, "Maybe you're sucking so hard that the conversations are drawn to you."
A gree corkscrew candle, lit. The flame at the top is blinding. It's in front of an empty fireplace.
A Whimshurst machine being cranked by a hand from out io frame. It's two big clear disks with metal foil on them, two foiled jars, two balls with a spark between them, and a base and support structure.
A plot of the temperature in my garage from noon to midnight. It slowly rises from noon to around 2:30, then suddenly rises steeply until around 4:30, after which it falls back down. The garage door faces west.
Ibises - white, long-beaked (or maybe billed) birds - pecking their way through the grass in a yard.
A plot from November 18th around 11 am to November 19th around 4 pm. The vertical axis is two slightly ambiguous measures of "gas" sensing. The green plot, from a BME688, is a broad gas sensor that has some kind of slow trend high to low across the plot. It spikes up around 3 pm on the 18th, and again (but smaller) around 9 am on the 19th. The orange line, from an MiCS5524, is spiky, unclear why, but it doesn't spike up on the 18th. Then, on the 19th, there's a big spike coincident with the spike in the green graph.
A brown praying mantis with a flash of bright green showing along its back. It has one leg splayed out over some bamboo. There's a brown leaf to the left.
Two jack o lanterns on a concrete porch. The left is a Lububu face (lu boo boo), and the right is Darwin and Gumball from The Amazing World of Gumball.
A plot of temperature over the course of three hours. Around noon it suddenly, sharply rises from 60.5F to 61.6F. It continues rising, likely because the sun is on the garage.
A plot showing data from a BME688 and an MiCS5524 gas sensor. Both spike around 11:48 when a car is parked near them. The BME (right axis) spikes, then falls back to baseline after about 45 minutes. The MiCS (left axis) spikes, dips, then rises back up and apparently levels off.
Three lit jack o lanterns in the dark. Left to right, the painting He is happy without eyes, carved into a pumpkin - a cartoon dog whose eyes are gaping holes. Cookie Cat, a cheshire-cat-esque character from Stephen Universe, with a two tone face split down the middle. A tiny pumpkin with a bee carved into the skin. This was my cat's pumpkin! The pumpkin is so small that the whole thing is glowing.
A plot over 24 hours showing the output of the two gas sensors. The BME data is a smooth green line that dipped last night and has been rising back up. The MiCS is a yellow line thag spiked a lot last night, but is generally flat (zero).
A 3D printed white enclosure mounted to a wall. There's a striped black and silver USB cable on the left. Inside the box is an ESP32, to the right an SCD41 CO2 sensor, below that a MiCS5524 gas sensor, to it's left an MMC56x3 three axis magnetometer, and finally to it's left a BME688 temperature, pressure, humidity, and gas sensor.
A jack o lantern on a concrete step with a window in the background and a bush to the left. A depiction of Kirby in a cauldron with stars and bats around is cut into the surface.
Two jack o lanterns on brick steps. Left: Woodman from Hilda. Right: Scary clown!
Two pumpkins on brick steps. The first has the faces of Finn and Jake from Adventure Time as well as Lucy from Disenchantment cut into the skin so it's translucent, and the second (back) has a classic worried looking ghost.
Three lit pumpkins in a dark room. Left to right: Woodman (face), a Korok, a goofy pumpkin with two big buck teeth - the candle in its mouth is visible.

The bottom of two packages of Numi Tea. The top is Matcha Toasted Rice, it says .039 kg CO2e per tea bag. Ingredients, 25%, packaging 17%, transport 12%, boiling water 46%. The bottom is Honeybush, it says .036 kg CO2e per tea bag. Ingredients, 18%, packaging 18%, transport 14%, boiling water 50%.
A rectangular compost bin in front of a fence, between two short trees. The bottom three layers of the bin are aged gray. The top two are fresh wood (beige-ish, pine maybe).
A purplish bag of Sabor a Jamón Ruffles chips.
A korok from the legend of Zelda, breath of the wild, carved into a pumpkin. It has a five pointed leaf for a face, it's mouth is slightly open, and it's raising its tiny arms into the air.

A plate with lemon slices, a small cup of some dressing, a quinoa pile, some kind of salad, and an octopus tentacle in the middle.
Bottom to top: a green NiMH battery. An electric toothbrush, without its housing, with a slightly larger orange NiMH battery inside it. The toothbrush housing.
A messy plot showing hourly electricity usage in kWh vs Outdoor-Indoor temperature difference in Fahrenheit. Data in blue is before the insulation upgrade, data in green is after. There are trendlines fit to each set of data.
A plot of hourly temperature vs time in Fahrenheit. The majority of it is 75 to 95 over the course of every day, then about a week ago it drops to lows of 65 and highs of 75.
A black and white cat sitting like a loaf at the edge of a doorway.

A yellow and red wrapper. There's a picture of... food. The lower right, according to google translate, says "+10% Walnut"
A brown vaguely rectangular lump with some white dust on it and what I assume is a rice paper wrapper stuck to it.
A plastic wrapped set of small plastic yogurt drink bottles, "yummy belly," in my hand. The nutrition facts say each bottle is 540 calories and has 105 grams of sugar.
