If #Blizzard2016 lives up to the hype, snow could pile up in feet instead of inches, threatening to bring the entire system to a halt. If that happens, the New York Metropolitan Transportation Authority will deploy its most powerful weapon.

Darth Vader.

No, not the Sith lord. The Jordan Spreader Ditcher. The 53-foot-long, 15-foot-tall, 160,000-pound monster rumbles down train tracks behind a massive black plow that swats aside snow drifts as high as 16 feet. One look and you understand the nickname.

More progress with the hand, now I need to find a source of power that is not the Arduino, so I can power all Servos at the same time so the fingers can perform in unison. Progress feels good.

Oops

My servos weren't working properly because my map values were wrong. I scaled 0-1023 volts to 0-255, which are the values of my potentiometer, instead of scaling 0-180. Wow. Literal days of my life wasted.

Technology at it’s cutest — The Bipedal Cycling Robot

In 2011, robot creator Masahiko Yamaguchi demonstrated a robot which can balance, steer and correct itself while riding a fixed-gear bike.

So, I finally got my new servo motors earlier in the week, and I began working as soon as I could, which was today, after a whole week of school and wrestling. I was excited to begin what could be a cool robotic hand, and as I was building the hand I felt great, and then I pulled out my laptop to run the code that controls the fingers, only to realize that the new servo motors that I bought has the same issue as the first servo motor in my last post. In despair, I took the servo that I was using for the thumb and attempted to hack it for full 360 degree rotation, which turned out to be futile as well. I guess I learned some important things from this experience, like figuring out how one would go about making a robotic hand with less than 50.00 to spare(in theory, my idea would've worked if my servos weren't pure trash), but I really am just disappointed that I wasted my money on crap. I am not very happy with China right now, but I should probably blame myself for being cheap.

So today I got an email from the department of engineering telling me that my overall engineering GPA has fallen below a 2.0 and that I do not meet the continuation requirements of the College of Engineering. #sobering

That DAMN programming class. I should have dropped it when I had the chance. Nonetheless now I have to make an advising appointment and request an academic remediation plan. Shitsnacks.

In lame mans terms: I’m not done for just yet. But I can’t fail anymore classes. But I shouldn’t be failing classes to begin with.

They’ll remove me from the College of Engineering as soon as they pry my TI-89 out of my cold, dead hands. I’ve put in WAY too much time, effort and tears to just give up now.

After hours of Honors Chem note-taking, I decided I needed to do something a little bit more interesting. I have been working on this robotic/animatronic hand/glove/thingy for a week or so and the project has been moving slow because I’ve been bogged down with the courses I take at school. I started it during Christmas Break and thought I would be able to keep pace when school rolled around. The project consists of a few servo motors, an old heavy-duty glove, my Arduino Uno, steel thread, and a few other miscellaneous supplies. I found a sewing needle in my house, put the steel thread through the needle’s eyelet, and made holes through the fingers of the glove to place the thread, which would be connected to the servo. I used a potentiometer to control the servo because I already had code for a pot-servo circuit from a different project, but I would like to integrate new sensors that I haven’t yet worked with. The potentiometer controls the position of the servo, which in turn bends the finger of the glove at a specific angle. I only have one servo motor, so I could only do one finger, but I ordered more and they are on their way. Also, the servo I have does not have a full 180 degree range of motion, which I chalked up to a factory defect; it has 59% less range than it should have. While I wait for the new servos, I’ll try and refine the structure of my hand. PS - I would've put a video of the finger moving, but the servo only rotates so little that the finger barely bends, which is kind of disappointing.
