Python Beginnings

You woke up this morning and headed to school. You finally "started" your Senior Project, by getting Miss Jensen's signature on your project sheet. After meeting up with Nick and Liam at the school, you headed to Nick's. At Nick's you measured the distance around the two pulley systems and added timing belts to the McMaster cart. You then brought a 12v battery and amp clamp back you your house to test on the stepper motors.

At your hose your spent a while reading more about MJPG-Streamer, but got nowhere. You decided to start writing the RoboGoby Python software (snapshot below).

After a few hours you, Nick, and Liam went to Liam's house for lunch. Lunch was very good. You ate 3 sandwiches!

After lunch we stopped by Nick's to pick up a stepper motor and then went back to your house to test its Amp draw. Sadly, you did not have time to get it working because of frisbee practice.

At 14:30 you went to frisbee practice and had a long scrimmage, but you were very tired. After frisbee you went to swimming. After swimming you went home, finished the Physics final, tweaked your brochure.

To you it seemed like a long day.

Still at School (5/5)

Your name is Liam Wade, and you just started your first days of Senior Projects. Durring your first day of Senior Projects you could be mistaken for thinking it was a regular school day. You had to attend Jazz Class, Chorus, AP Calculus, and AP Physics. You couldn't find time between classes and extra curricular activities to work on the project and thusly failed to achieve much of anything. Y'all collectivity to begin writing journals in 2nd person. Tomorrow you hope to accomplish great success in the development of the float. Your plan is to switch from the pre-determined wooden design. Once the school day ended you had hoped to go to frisbee practice however the Calculus final proved longer than expected and denied you from attending.

MATH and more MATH

You woke up today ready to take the Calc BC Exam. It took around 5 hours. You liked most of the questions except the infinite series ones...

After the exam, you went home, baked some bagels + red peppers + provolone, and sat down to eat. While you were eating, Josef and Nick almost ate ALL of your favorite ice cream (which is Moose Tracks). After eating, you went down stairs and continued testing MJPG-Streamer. Tomorrow you think you'll make your own MJPG-Streamer node giving you all a constant rtsp stream (without a web server). At around 16:00 you carpooled over to Cumberland Fairgrounds and battled Casco Bay High School frisbee style. You had a decent game, but wished they had been a little better.

After frisbee you went home and ate, washed dishes, took a shower, and then headed over to Nick's to finish up V2:1 (first half of float V2). You worked efficiently! Below is the finished product (and Nick)!

B.N. - Tomorrow there will be an longer, more explanatory post about Float V2 on RoboGoby's Project Blog.

Nick + Float V2:1

Calc B/C

Today you, Nick, took the AP Calculus B/C test and the community library. This took almost 5 hours, from about 0800 to 1300. You didn't s find it quite as hard as you first expected, but there were more infinite series questions than you would have liked…

After testing you, and the rest of Limbeck, went to Travis's. While there you all ate lunch and then worked on video streaming from the BeagleBone and Raspberry Pi.

Around 1600 you all left for the ultimate frisbee game against Casco Bay High School. The game went pretty well and you won 13-3.

After the game you and Travis built what should be the final version of half the float. This took about two hours, from 2015 to 2215. The product looks good and you expect to write a blog post on it tomorrow.

MJPG-Streamer...Yet Again

You woke up toady almost as excited as yesterday. You went to Calc period 1/2 and had a good time practicing AP multiple choice questions. After math, you left school with Josef and went to your basement to work on getting a reliable video feed. After testing the Raspberry Pi Camera with Netcat (networking software) and MPlayer (video playing software), you decided to install MJPG-Streamer on the BeagleBone Black.

BeagleBone w/ Webcam

This was not hard, as you had already done it many times before on the Pi. After installing MJPG-Streamer both you and Josef were delighted to see less <.1s of delay! To bad you were viewing it from the Webserver....after running it through VLC and optimizing the speed you were able to get a feed with <.5s of delay. You took a picture of the difference between the webserver (right) and VLC (left):

After Josef left for English and Liam for Latin, you went to Nick's house and he showed you V2 of the float (which he and Liam had been working on). It was very nice compared to V1. You and Nick then tweaked the blog (RoboGoby) and made it look even better!

After a fun, but windy Frisbee practice you went to Swimming. Swimming was fun, but you sure were tired. You drove home, ate, did a few things, and then went to Nick's at 20:15 to finish up part of float V2. While at Nick's you attached the second stepper motor to the float (the one used to neatly organize the tether) and created the second half of the pulley system used to organize the tether. After you successfully helped fix the bandsaw (it was really Nick's dad that fixed it ). All in all it was a good day.

Taylor Series & Float Building

You had to go to math period 1/2, so it was an early morning as usual. In math you practiced multiple choice questions for tomorrow's AP test (for which you also have to wake up early!). The most annoying problem was one concerning a Taylor series with e in it, however you have now mastered the trick to doing similar problems.

After math you and Liam went to your house and worked on creating the second prototype of the float. You guys worked from about 0945 to 1215 This one looks much more promising than the last and you are excited to make a final version of it. After lunch Liam left, this was followed by Travis arriving around 1300.

Travis and you worked on remastering the blog as it was getting unorganized and there were a few issues. The new blog looks much better however and though it took a while you feel it was worth the time.

After that you all attended frisbee practice from 1430 to 1630, it was a little difficult because of the wind.

Later, from 2015 to 2144, you and Travis got together again (after he swam) so that you could continue work on the float, adding the last motor to complete the prototype.

FOLLOW THE [new] BLOG (5/5)

You woke up on the first day of Senior projects and you were ecstatic to start another blog! After your extreme success on the RoboGoby Blog you were ready for more. Soon after the excitement died when you realized that this was not actually the first day of senior projects and that you had to be at school within the hour.

You went to school and presented about Pinochet's Genocide in Chile for WHAP. You had a great time presenting. After WHAP, Nick, Josef, and you split up. Nick and Josef went to get the 4-inch PVC for the sub, while you stayed at school with Liam and wrote RoboGoby's April Update.

After you got your teacher's signatures in order to leave on Senior Projects, you ate lunch, and then went to physics. To you, physics today was the same physics had been all year long.

After school you went to frisbee. At Frisbee you ran around and threw a plastic disc through the air. Afterwords you finished up a WHAP essay and then went to Model UN. At Model UN, you created a resolution that would harness the economic value of exploding whales (previously dead of course).

After Model UN you finished up your position paper, and researched different transducers/video streaming software for the sub. You then went to sleep.

You've decided to include an image/video with each blogpost (as seen above).

You had a great first day of Senior Projects!
