Who's jtl3?

Tri-X, not Ilford...

I'm an electrical engineering student at Case Western Reserve University, hopefully graduating in 2014. I have a variety of interests and skills related to that field, and some entirely unrelated!

I have undertaken and am currently undertaking a variety of projects, mostly out of my interests in electrical engineering, physics, chemistry, and process control. I am a photography minor, which through building a darkroom in my basement, I have expanded that interest into industrial radiography with a Hewlett-Packard Faxitron unit I acquired surplus. Many of my photographs are also online.

I enjoy collecting surplus test equipment, and have acquired a sizeable collection, most of which I use regularly to support my projects. While most vintage / used test equipment is surprisingly reliable, I have out of necessity acquired significant experience in repair and calibration of these units, and it is out of my need to repair my instrumentation that I have tried to acquire a large manuals archive at this site as well. I also repair and calibrate instrumentation as part of my duties in working as a lab technician at Case Western Reserve University's Sears Undergraduate Lab. I specialize primarily in Hewlett Packard instrumentation, but am familiar with Electro Scientific, GenRad, Guildine, Philips, and Boonton.

Previously, I worked for SAND Holdings, LLC in Atlanta, GA developing embedded hardware, including their product NetDefib. Currently, I work for CWRU not only in the Sears Lab, but also for a much newer venture, Think[box], under the mechanical engineering department. In my spare time, I am also working on getting a company surrounding industrial radiography and the commercialization of some of my electronics projects called Telemark Six Instruments LLC.

I am an Eagle Scout, and I am happy to have my experiences in Scouting, as they have significantly contributed to my abilities in solving the problems I encounter every day. My other hobbies include playing the electric bass, being an occasional DJ at WRUW-FM 91.1 Cleveland on an electronic music show called Superhet, and participating in amateur radio at home and at CWRU, licensee KJ4HNN. At Case, I have also participated in an organization called the Tesla Orchestra, where I have both designed circuit boards and documented our fun, like this video of the Legend of Zelda video game theme song...
