Missing Entries

Sorry that these are late.

Week 1: March 31 - April 5
First week back from MacWorld and spring break; this week I looked forward to what was ahead this quarter. We planned out buying a new drone, and investigated what we would need to get the Fatshark FPV system (which came in over break yay!) up and running.

Hiro and I have looked at an alternative option to simply re-puchasing a Phantom 2. This option is more of a homemade drone, with components from DJI. It is called the flame wheel. It is intriguing, but I looks as though we will stick with the Phantom 2.

Week 2: April 8 - 11
This week was spent mostly looking at the Fatshark. We have found that the Phantom 2 has only one port for both video and power to the fatshark. In order for that to work with our fatshark, we will have to purchase a cable that will connect the two into one. For photos please refer to Hiro's weblog: http://physics.hpa.edu/users/hueno/

Week 3: April 14 - 18
New Phantom 2 shipped! Should be here soon. For now we are working on getting the DJI Bluetooth datalink to work. We have not had any success so far.

This week Hiro and I also made a VLOG to describe some of what we've been doing. Link here: http://physics.hpa.edu/users/bleckel_bo/weblog/adb00/VLOG.html

Week 4: April 21 - 25
New Phantom 2 is up and running. Now that the combined cable for the fatshark system has arrived, we've installed the fatshark on the drone. We've got some very cool results so far just from testing out range and functionality of the fatshark. Very cool product!

To the finish line!
For the rest of the time Hiro and I worked on flying, and fixing all things Phantom 2. We got some great shots using the FPV system, and I am very excited for the coming summer and the possibilities of this new set up. Hopefully we will be able to pass on this project to upcoming juniors and seniors. Jack Solomon has shown interest, and is a good option since he already has Phantom flying experience. Davy and Michael Ho have also expressed some interest in using the drones in various ways. Hopefully, with what Hiro, Kenji, and I have learned, the process of flying these incredible tools will be much easier for them. I wish them the best of luck next year!

Week 2 3rd Quarter

This week, we worked a lot on these oscilloscopes. We learned a lot about electrical engineering, and it was a really fun experience.

To the Finish Line

For the rest of this year, I will be focusing on the Fat-Shark goggles and the drone with Hiro. We plan to do a few things with this including aerial VRs, super accurate videos of specific things.

Quarter 3 Summary

This quarter, I started out working on the Arduino. I learned a few things, about programming and circuits.

To begin, I created a simple light: http://physics.hpa.edu/users/bleckel_bo/weblog/9b985/Arduino_Day_1__1814.html

Next, I worked with a potentiometer. Eventually I ended up making the potentiometer work to control a servo: http://physics.hpa.edu/users/bleckel_bo/weblog/44a1f/Arduino_Day_5__12214.html

Then, Hannah began working on her LED cube, and I wanted to help, but I got caught up working on Drone things. Here are a few links to Drone work that I have uploaded this quarter:

2/7/14

This week was short and we only had two classes. The first class I spent working on the drone still fixing problems and trying to connect the bluetooth datalink. The second class (Thursday) hannah decided that she would start making a LED cube with the arduino. The cube is a 3x3x3 cube made up of 27 LEDs. Here is an example: http://www.instructables.com/id/Arduino-LED-Cube-3x3x3/

2/1/14

Friday, and over the weekend, we worked on the drone. We planned to finish up Nathan Myhrvold's property project, but the drone was broken.
Friday, we received the DJI 2.4 ghz Bluetooth data link. This is essential to our project, as it allows us to control the drone by google maps and an iPad. But in order to install it, we has to disassemble the drone. This created a problem as we accidentally unplugged a wire. So Saturday, as we were preparing to head down to the Kohala coast, we were delayed. We spent a few minutes, and quickly fixed the issue. But soon before we left we realized that we lost control of the gimbal. So, we spent almost three hours trying to fix that problem. Finally we fixed the gimbal (amazingly without any use of any makeshift parts), but it was too late to do the project. Here are a few photos of our problem solving sessions.

Arduino Day 6 - 1/27/14

Today, we got new Arduino Kits!! They come with an Arduino Uno, the usual jumper wires, one servo, one motor, a bread board, a few resistors, a handful of LEDs: big, small, red, green blue. It also came with a set of switches and buttons.

Arduino Day 5 - 1/22/14

This is what I've been working on for the past couple days. It took me all last class and some of this class to figure it out, but I finally did figure it out. It's pretty cool!!

What it is, is a bar graph made out of LEDs and controlled by a potentiometer. Next steps, maybe change the input from the potentiometer, to a microphone to show music levels (Luigi's idea).

Day 4 - 1/15/14

Today we flew the drones around basically for the entire class. Here is a link to some of the footage that I got with the new Zenmuse H3-2D gimbal for the GoPro Hero 3+.

Arduino Day 2 - 1/9/14


Today Luigi and I tried to make the LCD work. We failed :(. But only because we did not know how to attach the switch to the circuit. We followed the instructions from this page: http://arduino.cc/en/Tutorial/LiquidCrystal
On that page, we followed this diagram:



But, we got the servo working!

Download file "IMG_0601.MOV"

We also got the potentiometer to work with the servo to control the position of the servo, but ran out of time before we could film that. http://arduino.cc/en/Tutorial/Knob

Arduino Day 1 - 1/8/14

Today was the first day back from winter break. We broke into groups, and worked with either the Raspberry Pi, the Phidgets or the Arduino. I worked with the Arduino.

I messed with it for a while, and eventually made a simple circuit that ran a simple. pre programmed code to make a LED light bulb fade in and out.


I did all of this by following a few simple instructions on the Arduino website (http://arduino.cc/en/Tutorial/Fade), and a little critical thinking.

Last Day Treasure Hunt

http://physics.hpa.edu/groups/scienceseminar/weblog/96a76/Treasure_hunt.html

Here are the things that Tori and I found from the hunt

Task #2:

We found the meter was metering a lightbulb because we notice that it was reading 14-15 volts. We also physically found the energy meter so we knew because of that as well.


Task #1:

We found the access point while it was named Devlish Flow. (The Go Away SSID was from earlier). We changed it to HI.





Task #3:

We found the text file with my information on it in the Herobrine machine. Then we created a file named aloha and put it in the Herobrine machine.

Sensors/XML

We talked about this, but I can't find any solid notes on it. So here is what I have to say on it: XML is a language used like HTML (http://en.wikipedia.org/wiki/XML). We use XML at the Energy Lab to transfer data from sensors, to the network where we can access the data and view the outputs/inputs.

Patch Cords

How to make a patch cord:

strip the wire, then untwist all eight wires. set them into this order:

orange-white
orange
green-white
blue
blue-white
green
brown
brown-white

then, slide the wires into the plastic connector, and make sure that the wires are still in the same order. if they are in order, use the crumper to crump the plastic connector onto the wires.

2.20.13

Today, we worked more on wireless. We set up a bridge connection between two different antennas. Tori and I worked together, and we started with two "bullets". (I would put up pictures, but the pictures are on my computer at the Elab and I don't have them with me).

After bridging two bullets with antennas on them, we bridged the 15V pico station to a bullet. Then we bridged a NanoLoco M5 to a NanoStation M5.

A lot of today was review of things that I had learned a few years ago, but it was good review. I didn't really remember the settings very well so today was a good refresher.
