Replace the GoPro Ribbon Cable with a Socket Connector

I felt I was having to be extremely cautious with the ribbon cable on my H3-3D Gimble, every time I needed to get to the memory card on the GoPro. After doing some research, I found a connector modification to go through the connector on the back of the GoPro to achieve the save desired function (Power and Video Out).

This is where I found the socket connector: http://www.amazon.com/gp/product/B00NLA33KA?psc=1&redirect=true&ref_=oh_aui_detailpage_o08_s00
Remove the two screws, and the sticker across the back.  The back plate should come off.
While looking from the back, gently flip the plastic tab up, to remove the ribbon from the socket.
Insert the ribbon from the connector with the blue support tab on the top, make sure the ribbon is seated all the way. Flip the tab down to secure.
Angle the connector into place, and it should snap into the slot. Put the black sticker back on across the back, and re-attach the plate.

Now you don't have to worry about tearing off the ribbon cable before your next flight.

DJI Phantom Controller Stickers


Original Controller
The original controller that came with the Phantom is perfectly functional, but I didn't like keeping the paper wrapper on while flying. I was worried about it getting messed up, or in the way. I thought there must be better way to have the same information.
I took off the paper, but I didn't like not having the useful information available to me, especially if I wanted to let someone else fly my Quadcopter.

I found a lot of stickers online, but the ones from UAVStickers.com seems to be the best quality, and design.
I found these on Amazon.com

Applying stickers
I recommend using a pin/needle of some kind to minimize the oils from your fingers getting on the adhesive, so they will last a very long time. I cleaned the plastic with alcohol wipes first, and let it dry before applying stickers.

Bellow is the controller with the stickers attached, and it looks great.

Wildflowers in the IWV

Goldfields with Owens Peak in distance
With over 4 inches of rain between Nov 1st 2014 and March 1st 2015, the area is seeing quite a bit of flowers, especially when our yearly total of rain is around 5 inches. Take a drive behind the college and you will see many great flowers. The area is predominantly Goldfield, but you will also see the Desert Dandelion on the edges of roads/trails all over the area. Blue Lacy Phacelia is seen near the bases of the creosote bushes. Another great area to visit is the canyons near the brewery. Short Canyon has brought some small fields of California Poppies, as well as a few other flowers.

Please remember as you go check out the flowers, do not pick them. They cannot leave seeds for next season when picked.

DOT/FAA Transcript for Proposed sUAS Rules (Feb 15th 2015) NPRM

Transcript from FAA Press Briefing on Newly Announced sUAS rules


These notes were transcribed during the FAA press briefing by Christopher Schmidt. I am re-publishing this to my blog so people using Google can find it. A recording of this FAA Press Briefing from which this transcript was made is available at http://www.uavexperts.aero/UAVgroundschool/UAVPressConference2-15-2015.mp3

========


Sasha: This call is being recorded. We will work to put together a transcript to put out early in the week. At this point, I would like to introduce Anthony Foxx.


Foxx:
Thank you Sasha for your patience this morning and for joining this call. Two weeks ago the US DOT produced a report highlighting the rapid technological advances taking place. Technology is not just changing the automobile it is changing aviation. The US wants to capture the potential of unmanned aircraft and we have been working to develop a framework to allow the safe integration. In recent years, we have begun a set of actions designed a series of actions to keep America at the forefront of aviation. We have a number of test sites; We have developed an exemption program; today we take another step forward with our small UAS rule.


From Entertainment to Energy to Agriculture, there are a host of industries interested in using UAS to improve their business. But for us at US DOT, the first threshold must be to keep people safe as we move to integrate UAS into our sky.


Rule addresses two basic safety issues: One Keeping unmanned aircraft well clear of other aircraft. Two, mitigating any risks to people and property on the ground. As a result we’re proposing some common sense safety measures to keep everyone safe. They’re things like not allowing flight of these aircraft near airports or more than 500 feet above the ground, or if you’re operating one, they have to be within your los at all times and you have to be able to see them within your own two eyes, not with binoculars and the aircraft must weight less than 55 pounds, and you can't operate it at night.


This does not apply to recreational users; there are already rules in place for that.


Safety issues aren't the only issues associated with unmanned vehicles. These vehicles raise privacy issues as well, which is why the president has released a memo on privacy which will guide how the Federal Government uses aircraft in our airspace.


We’re going to be transparent about use of this technology, we’re going to use it in a way that follows the law and doesn’t infringe on civil liberties.


I wanna thank the FAA especially for their hard work on this, and I’ll turn it over right now to Administrator Michael Huerta, who will give us more details on the proposed rule.


Huerta:
Today’s proposed rule is the next step in our continuing efforts to integrate unmanned aircraft systems into our nation’s airspace. As you heard from the secretary we’ve made a lot of progress. Last year we published a comprehensive plan and roadmap to safely integrate unmanned aircraft, and we also opened 6 test sites across the country for research into unmanned aircraft. We approved the first ever commercial operations in the arctic and we have granted more than 2 dozen exemptions for commercial use of unmanned aircraft in domestic airspace.


Today’s proposed rule is a big step forward in outlining the framework that will govern the use of small unmanned aircraft weighing less than 55 pounds.


This proposed rule offers a very flexible framework that provides for the safe use of small unmanned aircraft while also accommodating future innovation in the industry.
As you heard from the secretary: this technology offers many potential benefits to society.
Due to the size of a small unmanned aircraft, we envision that these aircraft could be used for a wide variety of activities, particularly those that might be considered dangerous


Under this proposed rule, these aircraft could inspect utility towers, antennas, bridges, power lines and pipelines in hilly or mountainous terrain. Academic institutions could use them for educational purposes or to pursue research and development. Small unmanned aircraft could also support wildlife conservation, or be used to monitor crops. They can help with Search and Rescue, and they can be used to shoot scenes in film and television. And of course there is a lot of interest in using them to take aerial photographs, for real estate purposes. In many cases, unmanned aircraft can do these tasks with less risk than a manned aircraft that might have to fly in dangerous terrain or bad weather. And in some cases, an unmanned aircraft could conduct inspections more safely than a worker who might need to, for example, climb a tower.


As a reminder, what we are releasing today is a proposed rule, it is not a final rule. Today’s action does not authorize widespread commercial use of unmanned aircraft. That can only happen when the rule is final. In the meantime, operators must still go through the current process for a waiver or exemption to fly. Also this proposed rule does not affect those who want to fly model aircraft as a hobby, or for recreation. They already can. You simply need to fly according to our model aircraft guidelines.


The FAA’s unmanned aircraft website has a lot of good information on how to fly your remote aircraft safely. As the secretary said, safety is our #1 priority. This proposed rule makes sure that we protect other aircraft as well as people and property on the ground.


The proposed rule accommodates aircraft up to 55 pounds operating at speeds up to 100 mph, and up to 500 feet in altitude. This keeps these small unmanned aircraft away from manned aircraft that usually fly at higher altitudes.


Also, unmanned flights would be restricted near airports and in certain airspace unless ATC gives permission. This is to provide a buffer between manned and unmanned aircraft.


This proposal would allow operation during daylight hours, and require the operator to be able  to see the unmanned aircraft at all times.


Rather than requiring a PPL, we propose operators obtain a newly created FAA unmanned aircraft operator certificate by passing a knowledge test focusing on the rules of the air. The operator must renew their certificate every 2 years by passing a written proficiency test. Before each flight, operators would perform a preflight inspection, just as pilots do today.


These small unmanned vehicles pose the least amount of risk to our airspace, and therefore, the rule would would allow these aircraft to operate without the need for an airworthiness certificate; Such a certificate could take a manufacturer 3-5 years to obtain; with the pace of innovation in the market, an unmanned aircraft could very well be outdated by the time it obtains a certificate, therefore no airworthiness certificate is needed. However, these aircraft must operate under a clear set of parameters to maintain safety as I mentioned.


The proposed rule also invites comment on a number of provisions; so that we can determine the appropriate standards. Particularly, we ask the question of whether there should be a category and special rules for micro unmanned aircraft. Those that weigh 4.4 pounds or 2kg or less. We’re asking the public to comment on whether such a category, and different rules governing them should be included in the Final Rule.


The proposed rule will be on the FAA’s website and goes into greater detail in all of these provisions.


The Unmanned aircraft industry is expanding greatly, and this technology has the ability to dramatically change the ways we use our nation’s airspace. We’ve been working tirelessly to address all the special characteristics of unmanned flight, so we can safely expand the use of those innovative aircraft in the use of routine operations across the country. Today’s proposed rule is a milestone in that effort. We’re doing everything that we can to safely integrate these aircraft, while ensuring that America remains the leader in aviation safety and technology.


Thank you for joining us today, I’d like to pass it back to Secretary Foxx.


Foxx: Thank you very much Michael. Sasha, I think you’re going to help folks figure out how to ask their question.


Sasha: For any reporters, please email your questions to laura.j.brown@faa.gov or to suzanne.emmerling@dot.gov and we’ll do our best to answer them.


First question from Joan Lowe from AP: how long before you think the rules can be made final? GAO estimated 2-3 years because of the requirements of the rulemaking process and expected large number of comments.


Foxx: I’ll start and Michael jump in. We believe this is an important step and we also value the input of the public in what we’re putting forward today. Want to hear from as many stakeholders as possible, and that will have something to do with how long it will take us to move forward. Let me say that we’re committed to the overall framework of safely integrating UAS into our airspace and this is a very step towards that goal.


Huerta: Yes, we are expecting a lot of comments. But we have provided a comprehensive framework within the NPRM which I think will enable us to focus our analysis of each of these comments and to integrate unmanned aircraft safely and to move as expeditiously as possible.


Matt McFarland, WP: Can you tell us more about the FAA approved knowledge testing center, what be an example of one, where might one take this test, and where does one obtain a UA operating certificate?


Michael: The rule lays out both of these as proposals; our objective would be that the knowledge testing center would be very widely available, and there are many organizations that would provide testing services. lOoking for here is to ensure that those who want to obtain the certificate have access to it as broadly as possible. In terms of the content of that, the basic thing that we’re trying to establish here is that this is fundamentally different than being a private pilot. A number of requirements that might pertain to being a private pilot simply don’t apply when you’re flying an unmanned aircraft. But what does is apply your ability to operate within airspace with other aircraft. THe test is really focused in that area.


Q: Jack Nicas WSJ: A couple questions. To clarify under the rules, once an operator has a certificate he or she can fly any UAS under 55 pounds commercially as long as it’s during daytime under 500 feet within LoS, is that correct. Once they have a blanket approval to fly commercially, is that allowable so long as they follow certain rules?
Huerta: Yes, as long as you’re operating within the framework and you have the appropriate operator certificate, yes, that would be correct, subject to the basic rules associated with safety and airspace called out within the rule.


Q: Air and Space News: If a UAS operator already possesses a PPL, will they still need a UAS operators permit?


Huerta: Yes, you can think of it as sort of an endorsement to your driver’s license, but it is a  much streamlined process, and again its principal focus is on the rules of the air. But again, what we’re seeking is comment on this proposed approach, and looking forward to how the public views that.


Part 2 of that question: Will any medical exam required as with a PPL?


Huerta: There will not be a separate requirement for a medical exam.


Q: Aaron Cooper, CNN: Even when all commercial use has been banned, we still see a number of close calls between UAS and aircraft; will we see more close calls now that more UAS will be allowed to fly? How will the FAA ensure that UAS comply with rules and ensure that they avoid airports and manned aircraft?


Foxx: Part of putting this rule out is taking another step towards establishing a framework for the safest possible integration of UAS into airspace. As we go through the comment period, and work with those who give us their feedback, we will either learn that we have done this exactly right, or we will find some ways that we can tweak it, to make it the strongest possible rule in terms of avoiding those issues and ensuring that we have the enforcement mechanisms that enable us to protect other users in the airspace.


Huerta: 2 dimensions, and the secretary touched on them. The first is education, making sure everyone understands what the rules are, and the rule sets out that framework, done a fair amount of that and will continue to do that; an indication of that is our know before you fly campaign that we’ve done in conjunction with industry that we started at the end of last year. We also have enforcement tools that are available; what we want to do is ensure that anyone who is flying in a careless or reckless manner that would be endanger the public or other users of the airspace, that we take appropriate enforcement action against those activities.


Q: Dan Roberts, Guardian. Can you talk more about for the requirement for LoS visibility; does this rule out use of drones for deliveries as Amazon has been suggesting; What do you make of their threat to take their technology abroad if they don’t get the regulatory reform they’ve been demanding?


Huerta: First and foremost that this represents another step in a process that has a lot of components. What we are very focused on right now is this very large class of potential users, the rule does contemplate LoS activities, but do permit the use of visual observers. Separately, we have ongoing: two activities that are continuing to push the frontier beyond that. One is a pretty aggressive research program to push beyond VLOS; and the second is the exemption process which the secretary referenced where we can consider specific uses that people want to put forward as the framework continues to evolve. This is not the final word on the full scope of UAS operations. This is an extremely important step. But there will be continue to be other activities that will address this industry as we continue to evolve. Mr. Secretary?


Foxx: I just want to underscore that the technology is changing very rapidly, and this is why we have a very comprehensive framework that we’re working through, of which today’s announcement is one feature. We’re not done yet, and we’re going to  continue working to ensure that we’re moving as quickly as possible but also as safely as possible to ensure that we integrate these new technologies into the airspace.


Q: WSJ: Any flexibility on the LoS requirement in terms of What happens when see and avoid continues to be further developed? Do you forsee that LoS requirement being changed by the time this rule is made final if See and Avoid technology is proven by then?
Foxx: One of the good things about a comment period is that it gives us a chance to get feedback and also if the studies that Michael just referenced continue, we’ll see. We are putting forward what we believe to be the safest possible approach at the moment. But of course we look forward to hearing back from the public.
Huerta: I would just add that we also need to look at this in context of what does this suggest with respect to the certification of the aircraft. But as the Secretary said, what we’re Looking for is for people to comment as we’ve framed this as we’ve framed these requirements going forward, and if there’s data or analysis they’d like to present as part of the comment period, we encourage them to do that.


Q: Congressional Quarterly Roll Call: What penalties will be applied to unlicensed operators? How does the FAA ensure operators are not flying beyond LoS for example to survey very large farms and ranches? How will the FAA even know if someone in the middle of Nebraska is not obeying Line of Sight rules?
Huerta: As I said before, we’re Focused in two areas. One is to educate people on what the rules are, and the second is to ensure they are not operating in a careless or reckless manner, and ensuring that we’re taking appropriate enforcement action as needed. What we’re laying out here is a flexible regulatory framework that can provide a clear roadmap for everyone of how this very large class of unmanned aircraft can can operate in the national airspace system. The rule as it becomes finalized will provide probably the most flexible regime for unmanned aircraft that exists anywhere in the world. So what we want to accommodate are the sorts of things that folks are looking for ultimately, but we need to do that in a staged way that supports the highest levels of safety because that’s what people expect of the airspace and the aviation system.


Sasha: Mr. Secretary, any wrap up comments?


Foxx: Want to thank everyone for joining us today. It’s an exciting day for aviation and for unmanned aircraft in the US. As I said before, our work is not done. We know that, and we’re going to keep pushing forward. I want to say again how much I appreciate the great work of our FAA team on getting us through the day.

Huerta: Thank you Mr. Secretary, thank you everyone for joining us, and we’ll look forward to receiving comments on the proposed rule.

Changing WalMart Multi Lights to Single Color Strands

These are the WalMart Multi Color LED lights, and they can be re-arranged to make a single color strand. This only works on the "Green Wire" based lights, as they have a sealed resister on the line to make the voltage correct for the LEDs. The "White Wire" based lights DO NOT have the sealed resister, some of the bulbs have resisters in the bulb case, so you cannot easily rearrange the "White Wire" based lights as you can with the "Green Wire".
The strands all start and end with Red for each section. That is by design. Look at these lights, the ones on the left go in a certain location, and the rest of the lights look like the one on the right. and can go anywhere.

These strands are about 35% Red, 35% Yellow, 15% Blue, and 15% Green. This makes the math for getting the number of strands you want of one color complicated. But for those that liquidated WalMart's stock, this should be easy to do.
If you look at the wiring, you can see most of the lights only have 2 wires going into the base. The ones with the 3 wires on the base is where the larger light bases (Ones on the left, pictured above) are supposed to go. Once you have it all built the way you want, you may notice one of the lights in a 3 wire base won't light, simply take that light out of the set, remove it from the base and flip the polarity, then plug it back in.

I think the LEDs have a small bypass in the LED themselves to allow the current to flow through, even when the polarity is reversed. This would explain why I could cram a 2 Wire light into the 3 Wire base, and the other lights will work.
Each light string is in 2 sections of 25 lights each. The separation point can be found when there is only 2 wires going between 2 lights (Each with 3 wires going into the base). Based on this, I believe these light strings can be trimmed into 25 light sections without any issues.
This one on the left is a 3 wire base, with a 2 wire light crammed in. The other lights do come on, but not this one. Just flip the LED in the base, and it will light, once plugged back in.

This method will also work on these type of lights from Lowes (As reported by Phillip Barnett): These ones seem to be built better, as there is no odd ports, or playing with the polarity of the LEDs to get them all to work.
Here are the colors on this C9 style set.
The clear led is what is in the yellow c9 bulb.
The resister is built into the plug, allowing you to change around the lights without any issues.
This is the socket for this type of LED lights. The LED is polarity set, and only goes in the correct way. The C9 case also plugs into the plug.


A WARNING ABOUT - "White Wire" (NO SEALED RESISTER ON THE LINE)

Resister on this LED heated up and melted the base. Most of the lights don't have a resister on them, but some do to correct the voltage for the set. Swap bulbs about, and you will either overwork the resister, or you will fry a few LEDs.
One would think you could do the same with the "White Wire" type of lights that are the same brand, not so. These are easier to move around, but are not compatible with the "Green Wire" type. This is because the "White Wire" type doesn't have the same sealed resister on the line.

This is a DIY project, and your results may vary, so this is AT YOUR OWN RISK.


The reason why this project worked well for me is because it appears that the original string is setup to drive the Red/Yellow lights which operate at a lower voltage than the Green/Blue. By changing the colors around and making single color strands, the Blue/Green might not be as brights as the Red/Yellow due to the voltage being slightly lower than they need for full brightness. This means that the Green/Blue strands would be slightly underpowered. This shouldn't affect the life span of the LEDs though.
