One of my hobbies is buying and selling crap on eBay; this has led quite a formidable collection of gear over the years that someone else once paid several million dollars for. These pages will slowly get populated with useful information.

High Framerate Imagers
  • Photron Fastcam Ultima APX - 1024x1024@2000 fps, 4/3" format CMOS camera.
  • Redlake MotionXtra HG-SE - 1280x1024@500 fps using a roughly 4/3"-format PB-MV13 CMOS sensor.
  • Basler acA1920-155uc - 1920x1200 155 fps global-shutter CMOS camera.
  • Imco UltraNAC FS-501 - 24 million (!!) fps image converter camera.
  • AJA Cion - 4K 120 fps global shutter "production" camera (in other words, it doesn't have the dynamic range to be classified as a "cinema" camera).
  • Photron Fastcam Ultima 512 - Absolutely adorable 1/2-scale version of the APX; 2/3" 512x512@2000 fps.
Low Framerate Imagers
  • View Camera - Not really an imaging device as much as a mechanical device.
  • Fairchild Imaging Peregrine 3041 - 4MP square (31x31mm) deep-cooled scientific camera.
  • Sinarback 54H - medium format back based on the "classic" KAF-22000CE CCD. The live preview runs at 1 fps and requires a rapidly blinking LCD shutter to work, but those piezos make some beautiful images...
Infrared Imagers
  • FLIR A65 - 30 fps 640x512 microbolometer, about as good as uncooled detectors get.
  • Amber Enterprises AE4256 - 1st generation 256x256 InSb focal plane array, 256x256@60 fps. The controller involves some kind of DOS-on-a-card computer and a ton of TTL logic, the sensor is cooled by an LN2 dewar.
  • L3 Wescam MX-20 IR imager - a much newer FPA that I was lucky enough to win on eBay. 640x512, outputs composite video, and is cooled by an integral Stirling cooler.
I also own an ever-changing collection of more mundane consumer cameras, currently a Nikon D4, a Nikon D500, and a Sony A7ii, that I use when I actually want to take pictures.

  • Supermicro X9QR7-TF+ - Quad socket 2011; a rather pleasant board that I really should write a build-log for someday.
  • Supermicro SYS-2026TT - 4-in-one dual socket 1366; currently running XenServer 7.1 fairly effortlessly. 
  • Tyan B7015 - The ultimate miner, dual socket 1366, four PLX PCIe switches, and eight x16 slots. The miracle is, it actually works! Currently populated with eight Tesla M2075's and running Ubuntu.
  • SGI Altix UV100 - Up to 96 sockets of Nehalem-EX under one system image. Not actually fast; the target customers are folks whose workloads are interconnect-latency bound and don't fit in the RAM of a single node.
  • IBM X3950 M2 -  Another gigantic NUMA system, 2, 4, or 8 4U quad-Dunnington nodes lashed together with a custom IBM interconnect.
  • Sun SunFire X4600 M2 - Octal Barcelona (Opteron 83xx). An incredibly beautiful server, top-notch build quality and serviceability. No longer particularly fast, but can be cheaply loaded with 256GB of RAM and is a wonderful box for virtualization.
  • Tyan S4985 - Octal Opteron built out of two motherboards stacked on top of each other. I got this thing so far as to POST, and then lost interest...
  • EVGA SR2 - the one and only king of enthusiast motherboards; I've owned three different ones and have loved them all. Dual-socket 1366, claim to fame is the unlocked base clock and voltages in the BIOS. (2016 update - wow, still fast half a decade out!)
