An uncommon object that involves ruby, sapphire, stainless steel and gold.
A high speed, 895fps video of a can of brake cleaner spraying. A very fast non-laminar stream is visible.
A video that shows a tin-on-carbon calibration sample viewed from 15x to 100kx magnification using a scanning electron microscope, stitched into a single smooth zoom sequence.
A heavy oxide and tungsten metal film is visible deposited in a rainbow pattern on the filament side of the wehnelt cup of an electron microscope.
Screenshot of a work-in-progress charged particle optics simulation software, showing traces of electrons being emitted from a narrow bar's surface, traveling between and being deflected by two charged squares, accelerating into a cylinder at high potential.
An overview of the cockpit of a Cessna Citation Bravo in the middle of an overhaul, with a custom diagnostics instrument attached to the avionics.
An optical CMM based on a telecentric lens and a high resolution camera, mounted on a large and high precision vertical translation stage. Flat backlight visible below.
Sipeed SLogic16U3 USB3 logic analyzer
A short 90-second video giving a very brief overview of how basic heterojunction(ish) diode lasers work.
This image shows an infrared thermometer, also known as a pyrometer. Inside is a small hermetically packaged metal can containing a thermopile. There are two images showing the thermopile as a general overview and up close. A reference thermistor that measures the base temperature is visible on top.
First handheld laser weld between 2.5mm thick square tube and 5mm thick plate. Both carbon steel.
Custom C&CS lens mount attached to the board
An image sensor test board, designed in KiCAD. 3D render.
Artix UltraScale+ development board blinking 6 LEDs with a 27-bit 100MHz counter.
Accurate, realistic 3D render of a high speed CMOS image sensor in its package. Bond wires, pads, and clear chip outlines are visible, as well as some of the PCB layout.
A brand new high speed image sensor, up close macro photos.
A 1500W air-cooled laser welder, hand next to it for scale. Wire feeder in the background.
A Mooney M20M(Bravo) single-engine, 4 seat, low-wing airplane.
Complete single-layer PCB without silkscreen, made by a fully automated system.
Video of TIG welding with neon gas. No subtitles.
640x512 thermal imaging core on a hand
A small collage showing the detector as-built, the photodiode, where it's installed, and a schematic for replication.
Soviet K573RF2 EPROM scanning electron microscope image
Motion stage with the cover off
Sample stage with visible signs of overtravel damage
Main control board with FPGAs, DACs, CPU, and everything else. Mostly digital, some analog.
Inside the microscope, with the top cover removed
Keyence VE-7800 scanning electron microscope, face on.
Pump vibration and noise isolation box, lid open
Ulvac OMT-200A oil mist trap. Original cartridge visible.
SEM leak detection using a simulated leak, an eyelash, showing long travel time from the top of the column to the detector at the forepump
Leybold UL500 mid-teardown. On the left is the sector mass analyzer, in the middle a turbopump, and on the right the valve and vacuum gauge block.
Leybold UL100 Plus helium leak detector being very unhappy and showing incorrect readings
Leybold Ecotec 500 sniffer thing, missing some parts.
Photo shows a Leybold UL100 Plus helium leak detector from the front. Black and white box with a control panel and KF25 test port.
Cryocooler cold end condensing water around it
Finished headband, top view
A semi-finished headband, after curing
A strip of butyl tape with all the wires passing through it, creating a resin barrier
Dry test layup, with an aluminium foil shield
Several rectangular strips of kevlar fabric laid out on a table
Scissors, modified with a fiber laser to add "teeth" for cutting kevlar.
NSK M-PS3030KN002 MegaTorque direct drive rotary actuator, with its cover open, showing a high resolution 3-phase selsyn/synchro analog position encoder.
A Nabertherm RT-50-250-11 tube furnace.
An exclusively visual meme, depicting a LEMO multi-concentric connector as a car cigarette lighter due to their exceptional similarity.
1.8kW high speed spindle from Jianken on the left, ISO10 tool holder on the right.
A very blurry picture of something interesting, but vague.
Render of a miniature numitron clock. Six tubes, in a 3x2 configuration, inside a clamshell metal housing with a plastic ring.
Small home toaster oven converted to reflow oven. White alumina wool insulation is visible inside. Original controls replaced by a generic REX C100 PID temperature controller, convection switch, and chunky power switch.
