Cyclops E with Alta Devices GaAS Solar Panels
08/08/2014 at 04:39 • 1 commentEquipment Specifications for the Cyclops-E
3 cell lipo/ li-ion 5-15 Amps 5-9 cruise
Demonstrated 2-3A cruise in tests with 6 cell for all electronics
Moving to 6 cell in the Cyclops C 3M would like to move to a hybrid automatic switching system like is used in the Aeropak series of hydrogen fuel cells. I would actually like to combine all three technologies in a larger plane next year. With the H-Cell 2.0 from HorizenFuelCell.com to run the electronics and provide a little dawn or dusk boost to the batteries or an Aeropak 500
Laminate:
Odroid U3 on board with Pixhawk for distributed/parallel processing and for operating Open CV
Drone Deploy 3G Cloud Communication
MARS Parachute Recovery
6cell 20,000 mAh Li-ion 18650 batteries
OpenTx with Openlrs radio control
Working on a catapult for autolaunch
Plane Specs:
Wingspan 2.75 meters 101 inches
Fuselage 52 inches
Wing Area 598 sq in
Tail Area: ?
Cruise Air Speed @ 6.5 lbs balanced 1.5 lbs of ballast 35-30mph
Max Air Speed 65-70 mph
Stall Air Speed 15-17 MPH
Climb Rate >2000 Ft/Minute
Integration of System on Cyclops-E:
61 Watts of Solar on the wing and tail
Blocking Diodes and Bypass Diodes wired on the wing. Connections to the plane are made through mxt connections.
Charging will be through two LM 2587 buck boost boards from east west hemispheres of the installation
On board battery will be 6 Cell 20000 mah li-ion will be able to handle smooth discharge and smooth charge. Will also be charging the battery on the ground when necessary. I would like to make a plug in load for on the ground so that the batteries can be charged and not worry about over charging.

Still up in the air is how do we switch to solar power and not the battery when we have enough power from solar?
Also do we need to dissipate power if the battery is full the plane is on the ground and the sun is out?

Odroid U3 in everything
08/06/2014 at 01:36 • 0 commentsIn the world of microcomputing few can compete with Ardiuno and Raspberry Pi. There are some new names like Hummingbird and Banana Pi but in sheer sales they pale in comparison and only offer a nominal jump in performance. For $65 you can own an Odroid U3 from South Korea. It is essentially a Samsung Galaxy S3 made into a microboard with ethernet, USB, HDMI and audio output. There are breakout boards and GPIO pins for any functions that you wish. You can run android or linux on the boards and they are extremely capable. I have several operating functions throughout my lab alongside Raspberry Pi's and Arduino. I will give an overview of the functions of the Odroid in my planes.
The Odroid U3 is a a 1.7Ghz Quadcore Arm Processor with 2 GB DDR3 RAM. I have a 16GB emmc card in each system. You can change the SD boot priority and use up to a 128 GB card in the SD slot for storage. I will be changing some systems to 64GB eMMc cards sometime in the future. I am running Unbuntu 14.04 LTS in my Odroid but you can also run Android 4.4 as well. I have three that operate as servers for various functions. They each have a 1TB External Drive for data logging and backing up. The Main server uses two 2TB drives in Raid 1 configuration as direct mirror backups of the entire complex. We also have offsite backup servers but I will not get to far into that in this post.
Our use of the odroids in this fashion are as follows. We have a single unit on board attached through a serial connection in order to communicate with the Pixhawk autopilot. It can recieve full sensor telemetry and it can send commands to the Autopilot based on image recognition software requirements. The Odroid is serving as an embedded linux computer to handle the heavy load the vision software will require. We will be working with a dynamic image recognition engine in conjunction with cameras operating in a Themal, HD Visible, and Multspectral modes. We will have more details on the software itself soon.
On the ground we will be using at least two Odroids in the central command station. The will be operating two to four screens and will operate multiple planes from a single user or from multiple users. The main control and data acquisition will all be cloud based and so can also offer views to multiple observers simultaneously. We will also be showing more of this soon. Thank you to all who are following our project. We hope to enter the hackaday prize with it as well. Thank you and we look forward to participating.
