Yo KITAs!

I'm always working on new segments and series for the show. I like to go a little out of my wheelhouse so that we spread out our topics, but this time I'm going WAAAAAAAY out of my wheelhouse.

I've been working on a new series called, "The Green Geek" -- in which I show how to grow plants indoors, move to making tech to ease the growth of plants indoor (think: Arduino controlled lights, fans, heater and irrigation) and end up with some cool segments on extracting essential oils from plant material. (Lavender!)

Is this something that interests you?

Anyone have any info on the RTFQuads Flip32+ F3 OSD flight controller. I bought it thinking Paul would include some documentation on what everything is and all I got was the board and the pin headers. It's got a built in OSD and I need to know how to wire it.

Also, is it possible to wire my Bluetooth adapter into it?

Don't know how much this helps, but here's a diagram showing the pinout.

Since the board already has the osd I would imagine just connecting your video transmitter would be enough to receive the info.

Aaah, just pick a pin and go for it! :-)

I would like to use my Raspberry Pi 2 as a WiFi access point. I went through the steps listed on the Adafruit site at:

https://learn.adafruit.com/setting-up-a-raspberry-pi-as-a-wifi-access-point?view=all

I implemented each step by doing a copy from the site and pasting the commands in a terminal window via Putty on my Win 10 PC. Everything seemed to be going well until I go the section titled:

First test!

I copied the command and got this result.

pi@raspberrypi~ $ sudo /usr/sbin/hostapd /etc/hostapd/hostapd.conf
Configuration file: /etc/hostapd/hostapd.conf
Could not open configuration file '/etc/hostapd/hostapd.conf' for reading.

It may by obvious that I'm not proficient in using Linux, so I can't understand what went wrong. Does anyone have a any ideas what the problem may be?
The WiFi dongle was included when I purchased my Pi 2 as part of a CanaKit.

I would eventually like to get an 801.11 AC high gain WiFi USB dongle for a Raspberry Pi based access point.
Would you like to use your Pi as a WiFi router? Or maybe have it as a special filtering access point? Setting up a Pi as an access point (AP) is a bit more advanced than using it as a client, but its still only a half hour of typing to configure. If you want to, this tutorial will make it so the ...

FYI for those who are having problems the issue is got to do with the latest version of Debian. In Jessie Debian they switched to something call systemd.
Systemd handles things differently than what was used in wheezy, so if you're following older how-to's and they don't work, then that may be your problem.

And since most of us RPI users are NOT linux admins your best bet would be to switch back to wheezy. If you have only one pi then use Berryboot or Noobs to switch between Raspbian Jessie and Raspbian Wheezy. Hope this helps.

I recently discovered KH and want to build the KH250 quad. I know there are some issues recently with RTFQ, so I was wondering if someone could recommend another retailer I could order parts from - or recomend another part list for a build

Or, if someone could point me some literature so I can better understand how to choose motors, ESC, etc, that would be even better.

ZERO TECH "Dobby" pocket drone
...Internally, Dobby will run on a Snapdragon 801 chipset, with 2GB RAM and feature 16GB internal memory. The internal storage will be used for snapping photos via the drones 13 mega-pixel camera or video at up to 4K resolution. Like similar drones the Dobby with feature a WIFI connection, GPS and GLONASS and there will be a smartphone app to control the drone rather than having a separate controller. In addition to standard ‘manual’ flight, the Dobby also has a follow me feature, and can be set to fly via waypoints.
https://youtu.be/_tX0NRmVN1I
Chinese start-up Dobby are crowdfunding a drone in China that can fold up and fit in your pocket and will cost just $260.

The CrashPlan client is Java-based so should run on the Synology. I've seen some how-to articles/videos saying that's possible.

The biggest problem I have with CrashPlan is the amount of RAM it requires. They typically say about 1GB RAM for each TB of data backed up. I've got about 4TB backed up though and it seems to have stopped around 2GB of my systems memory.

Hey so I'm wondering what is the best solution that you guys/gals know of for streaming from an Android smartphone to a Windows PC. I have a Samsung Galaxy S6 and I want to try to stream video of it to my Windows 10 laptop. I started googling it, and I got like a million different options, so I figured I'll ask you guys. It needs to be free, or really cheap and as little lag as possible.
What's your ideas?

It really depends on what you're wanting to stream. Live video from your camera, mirror image of your screen, or a video file you already have recorded on your phone?

Pet peeve (ok more like a major psychotic hatred)
Flashlights.
Why the FUDGE do they add in the beyond useless modes of strobe and S.O.S.??  Sure I've crawled under a machine and think, Hey, this is a good place for a rave, I'll put my torch on strobe!

There are some with just on/off, but you have to really scrutinize the listings.  I like the high/low, so I'm usually stuck with the other "functions".  If you come up with a high/low/off version, I'm in!
BTW: That strobe mode works great for my son's bicycle headlight!

The recent podcast covering the maker faire made a comment about makers shepherding the drone revolution. That's only true if you call all the members of the electric flight RC community makers. While the maker community has made some important contributions, the RC folks were building quadcopters before makers had faires. From what I saw, the maker community didn't get into the game until after the press came along and abused the word "drone" to get more clicks on their stories about people who were calling their aircraft multirotor or quadcopters.

I don't see any problem with that. Maker, inventor, engineer... It's a title. The "maker movement" has really just greyed the line a bit.

I'm going to be turning in my macbook pro when I change jobs this summer (also going to be leaving behind an iMac). My question is if there is a free software to erase the data from the hard drives? I've heard of "shredder" software. I don't want to delete the software on the computers, well at least the software owned by my employer.

Thanks in advance.

In the linux world there is a program called bleachbit, it wipes the empty space on the drive without harming the rest of the system. If there isn't anything like that for your version of osx you could try compiling the source.

I was just wondering around youtube and came across this guy. He owns a repair shop and does component level repairs on motherboards. While i may never do this type of repair i found it interesting. I personally think that laptops have become so cheap that usually a repair like this would be a waste based on some of the prices I've heard but i guess there is some business in it. Especially if the laptop is out of warranty and 2-3yrs old but it makes me want to get a few broken laptops for free or cheap and start messing around for fun.

I think it's about 110mm from rotor to rotor. Not totally sure on that. I'll let you know when I get it. But pretty small.

So I think I am missing something.
I went to Lenovo's website and downloaded the Ethernet controller drivers, installed them, and nothing happened. I have pulled some pictures together and I am posting a link to the Lenovo download page I used.

+Jason Perry doh! Not sure why I was thinking Dell.

I haven't worked on as many Lenovo laptops, but it seems like I had similar issues. I'd definitely try getting those PCI and SM BUS drivers installed.

If you have a USB wifi dongle, I'd give that a shot. I don't know which ones would just work out of the box, but it might be easier to get USB drivers working than the internal drivers.

Google to bring official Android support to the Raspberry Pi 3

Sounds interesting. Had to look up specs. 1gb ram for the pi 3? That may be a problem for android apps. But I'm very excited to get android on my Asus flip chromebook. lol

Hey!

Trying to find the episode with the feedback on extending wifi with a second router. Using a TP-Link TL-WR702N as the second router, but similar principles might apply.

I see reasons.  One probably runs MUCH snappier then GUI linux.  Test out apps, security research. And have up to date official Android over mfg/carrier lagging non supported versions.
And of course the typical geek reason: because I can. :)
