A bunch of new things in my life, but most significantly, I am now officially an Electrical Engineer! I graduated from Cooper Union as a Bachelor of Engineering (BE) in EE, and will next be beginning my graduation work. I figured I should probably post a news article about this, as I recall posting one when I graduated high school four years ago. As then, I'd like to share a brief overview of my programming plans for the summer. Unfortunately due to commitments they're quite brief indeed, but I do tentatively plan to try to bang out some if not all of the work I need to on Doors CS 7. We'll see how that goes. From my lessons of last summer, I think I'll forego making deadlines for now.

In other news, I was gratified to see that I recently passed Marcos Lopez once again to reach #11 of all time, with just under three-quarters of a million downloads on the venerable community calculator site ticalc.org. Here's to another quarter-million soon after I get Doors CS 7 finally completed.

The growing cost of automotive and airplane travel has recently made railroads a more attractive transportation option. In the golden age of railroading, wealthy captains of industry often had their own private train cars that would be hitched to passenger trains and used to carry them from city to city. Most modern railroads retain the provisions to carry private cars at costs of mere cents per mile, making the private railcar a cost-effective, comfortable, and scenic alternative to most other transport methods. CPRR1 combines a powerful, state-of-the-art diesel propulsion system with opulent quarters and amenities for an extended stay by one to three people as well as a train crew of one or two.

CPRR1 is a private luxury traincar meant to be used for short- to long-term journeys. The first preliminary designs for CPRR1 were drawn up around 1997 during the design of the Central Park Railroad (CPRR), meant to be a global rail system linking and incorporating many current rail systems and providing a unified rail network for passenger and freight transportation across town or across the world. CPRR1 was intended as my own private train car. The first designs connected two 40-foot sections with an articulated hallway, similar to the design of some short-distance commuter buses, but that design was eventually discarded as impractical. CPRR1 evolved into its current form, an 80-foot long, 10-foot wide car incorporating a cab and motive power in the front 20 feet, a sitting room occupying the next 20 feet, and bedrooms, a kitchen, and a bathroom in the back half.

I've detailed my plans for CPRR1 in a technical report with fifteen renders and associated descriptions. Enjoy!

After a few months of tossing this idea around in my head I recently constructed the Multichord, a single-stringed musical instrument that uses a hard drive to vary the tension in the string. It can play a full octave of notes by applying specific tensions related to the voltage applied to the hard drive's read-write head, as produced by an array of power resistors. A musician sets the note with pairs of buttons on the end of the instruments, then plucks the string to make the note.

I have detailed the project with photos, a video, and plans and schematics below. Check out the video below and click through to the Project Page for all of the information.

This one's not an April Fools' joke, I'm happy to say. Over the past two weeks I wrote an extensive technical report on the construction, coding, and performance of Simms AI v1, the first incarnation of my self-trained, conversational neural-network-based bot. It's over a year since Simms AI first went online, and 2 million neural connections later, it was time to evaluate its functionality and start looking towards the next version. It is currently online under the screenname SimmsAI should you wish to chat with it; be patient, it lags sometimes. This report explains how it parses and constructs sentences, how its custom thread-management system is structured, and how Simms performs technically and linguistically. Please check it out below and give me feedback, either on the report, on Simms v1, or on the upcoming Simms AI v2.
