I recently got a DJI Phantom 2 Vision+ at the recommendation of TheWireCutter’s “Best Drone” article and I’ve been loving it. I keep it with charged batteries in my car now and yesterday I flew it up above the flooded area of Houston outside of downtown (see photos and videos below):
It’s easy to fly– it’s got some sort of gyro stabilization mechanism which means it does a good job of hovering without any work on your part as the pilot.
Camera video is incredibly (and eerily) smooth: the gimbal the camera is attached to stabilizes the camera and does an amazing job. Everyone that sees the videos comments on this.
Camera is included so the package is all-in-one– no need to pick a drone and then figure out the right camera.
Image quality is really good– but not great (like not SLR great). I don’t know how it compares to a GoPro, but I’d imagine the quality is similar. It’s a little telephoto thing, not a lot of glass/plastic in the lens so one can’t expect that much. I’ve been shooting with SLRs all my life, so my standards are high.
Hardware is pretty robust: I’ve crashed this thing once or twice and surprisingly didn’t break any blades or the body. Once I managed to land it in grass upside down– no damage. Another time I ran blade first into a brick column and it subsequently hit a brick laver driveway (falling from only about 5 ft). Again, no damage. I don’t want to encourage you to be reckless with it. Since these two incidents, every landing has been super smooth for me (one learns). But I’m pleased with how the hardware can take a lickin’.
Video files are standard MP4s and can be played back in Windows Media Player, Quicktime or VLC Player (then again, what *won’t* VLC player work with?)
Auto return-to-home feature: the Phantom 2 has a cool feature where it senses if you won’t have enough battery to return home, and flies itself back to it’s starting GPS position. I’ve had this kick-in once and was impressed with how accurate it was (it landed about 2 feet from where I had taken off from).
Other commonly asked questions:
How far can it go? If I read the manual right, about 800 meters or half a mile.
Can you carry it on an airplane? In fact you can! I traveled with mine from Texas to Lousiana.
How long does battery last? The drone battery lasts 23 minutes. The controller battery lasts a while, probably 20 flights? And the range extender battery lasts probably about the same 20 or so flights. Yes, there are three separate batteries. Yes you have to charge two of them (the latter two use micro USB, the former is charged with the custom charger that comes with the kit)
Drones are going to get smarter (more computer vision for object tracking and collision avoidance and other crazy features such as those found on the recently announced Lily) but the Phantom 2 is an excellent starting point.
Here are some images I took today flying my drone over Houston buffalo bayou park where there was massive flooding yesterday:
I’ve had months and months of issues with pairing my iPhone 6 and my Tesla Model S using Bluetooth. And I’m excited to say that think I’ve finally solved the problem!
The problems I was having:
Phone would randomly disconnect and then re-pair with my car. Sometimes this seemed to happen every 60 seconds. Happened during phone calls and while using Bluetooth audio
Sometimes the phone wouldn’t pair at all– in some of these instances the Bluetooth logo on my phone would be lit up.
Solution? I had a Tile tag on my car keychain. I got rid of it and the pairing problems went away.
Tile uses BLE (Bluetooth low energy) so I guess that my phone’s connection to the Tile was somehow interfering with its connection to my Tesla Model S… something for Tesla to fix in their Bluetooth implementation.
I’m just happy to once again be able to talk hand-free and listen to music from my iPhone while I’m driving.
There’s no shortage of fear mongering about technology and our young people. A quick search on Google News for “Instagram teen” reveals headlines such as “Akron teen robbed… by man he met on Instagram” and “Teen shot at party advertised on Instagram.” The message here is clear: “The sky is falling!! Snapchat/Facebook/Instagram are to blame!!”
Increasingly, our lives as adults are mediated by technology and it’s hard to imagine it being any different for our children. So, how can we get beyond the headlines and understand and, as parents, the role of technology in our children’s lives?
In “It’s Complicated”, scholar Danah Boyd presents the findings of 166 interviews conducted with teens from 2007 to 2010. Boyd goes to high school football games and into schools and homes and to better understand teenagers and technology today. Her conclusion: teenagers today are motivated by the same things they were motivated by in previous generations– the desire to hang out and connect with their friends and to find their place in society. Instead of connecting at the mall, teenagers connect on Instagram. Instead of spending hours talking on the phone, teengers text and Snapchat. While academic, I find Boyd’s writings on online privacy, bullying and safety accessible and highly credible, both thanks to her conversations with teenagers.
A few weeks ago I hosted the @BeingHouston account on Twitter and ended up getting a tour of Amaya Roasting Company. I’ve been buying Amaya coffee beans for probably a year now and frequenting their coffee shop Catalina Coffee so I was stoked to see their bean roasting operation.
Amaya is located in the back of this building in East Downtown (EaDo) though the gallery is out of business:
Here’s Max outside entrance to @AmayaRoastingCo. It’s their coffee at Hugos Houston, Backstreet Cafe, CatalinaCoffee and a lot of other local establishments:
Green beans = unroasted coffee beans. They feed in 18 lbs into roaster, it comes out 15 lbs b/c water evaporation. The curve shows the temperature – time graph that they take the beans through when roasting them.
Bean moisture is very important. Too much could lead to fungus. Too little isn’t good either. Moisture testing machine.
They hand control temp over the 12-15 min it takes to roast a batch, but they log the actual temp curve in this software.
Cupping setup Amaya Roasting Co. Same beans but roasted light vs normal to show the difference roasting makes on taste (I was short on time so we didn’t do an actual cupping)
These decaf beans were roasted while I was at Amaya Roasting Co. The beans are being cooled off here:
This is @AmayaRoastingCo’s small batch roaster, made in USA. Same as big1 one but used test roast small batches.
And this is the big roaster:
Max doesn’t regularly give tours… Yet. They’re moving into a new space that’s a lot bigger in the next few months and when they do Max plans to do tours and cuppings on a regular basis.
Tip for fellow Houstonians: download the Houston 311 app. I used it to submit a ticket (with photographs and geolocation) about five really bad potholes near my office. And I circulated the link around my office to get the ticket upvoted. Less than two weeks later, no more potholes.
A few weeks ago, I happened to catch a Houston City Council meeting where a bunch of Houston limo operators spoke out against Uber (thanks to Evan Mintz tweeting about it). Their arguments (if they could be called that) were mostly protectionist and some were more vehement than others. But none of the remarks were more ridiculous than those of Joe Jordan, the President of the Houston Limousine Operators Networking Group. He somehow managed to compare Uber to child pornographers! Here’s a video clip of his remarks:
“The problem with a company like Uber, they only exist in cyberspace. They’re like people who do child pornography or people who do online gambling. They simply move their websites to South America or China.” -Joe Jordan, President, Houston Limo Operators Networking Group.
Like child pornographers? Move their servers to China??
Incredible how uninformed this guy is. Chris Sacca hit the nail on the head in a back and forth on twitter while this was happening:
After the news on Sunday that Tesla’s 1st supercharging station in Texas will be in San Marcos, Texas, some Tesla owners did some further sleuthing and here’s what the map looks like for the 1st 4 Tesla Superchargers in Texas:
This morning, just for fun, I drove down to the Outlet Mall at San Marcos to see if I could find the Superchargers. I did.
While taking the pix below I casually chatted up the workman. The spoke openly, answered all my “casual” question, and had apparently not been sworn to secrecy. Here’s what they said:
1. They are here from Florida and work for a Florida company that is the subcontractor for the six Texas SC stations.
2. Their company is also going to be installing Superchargers from Florida all the way to Maine. There are other subs for other parts of the country.
3. They will finish San Marcos this week, then move up to Waco to begin work there. That job should take 3-4 weeks. The guy wasn’t sure exactly where in Waco they would be (he already had the plans but hadn’t looked at them and didn’t have them at hand).
4. At about the time they start in Waco, another team should be starting the installation at Columbus at a “Comfort Suites or something like that.” I’m guessing it will be here: http://www.comfortinn.com/hotel-columbus-texas-TXF22/Hotel-Map?maphotel=TXF22&country=US
5. Next installations after that will be Huntsville – after that he had no info except there are six total in the works.
About San Marcos:
The chargers are in a large parking lot to the east of the main mall buildings and Neiman-Marcus Last Call
Note that there are 5 chargers in place. Each of those two wood enclosures in the background contains 3 cabinets (6 in all), and each cabinet is capable of supporting two Superchargers eventually, total of twelve.
Those two green transformers in the background were just installed by the power company, one for each of the two groups of cabinets. That’s some SERIOUS power coming in!
Note that they’ve already re-sodded the lawn. You can see that everything has been dug up for the big underground conduits which also go under the street to the actual charging stations (after which they repaved the street).
