# The Dark Pi Rises

### Interesting..

My today's visit to raspberrypi.org blog is much more exciting than any of my previous visits. Your Pi + Robotics projects are very interesting. I am curious to know about how does the camera connection and how does Pi + Arduino communication happen...

Good luck,

### Nice work!

This looks great, and thanks for posting. Any chance you could fill us in on what wifi hardware you're using?

### Great Project!

I'll be following your blog! P.S. Looks like the embedded object (below the first still of the Dark Pi) is not working FWIW. I assume the Pi connects to the Arduino via TTL serial? Also, have you looked at the Beagle Bone? Can you compare the Beagle to the Pi?
Thanks!

### OMG

The video started working, it is a riot! Nice Job.

### great video

can you send me some details of the video editing tools you used to create your work, It looks great and i'd like to know how you did it.

### Hey!

Very good work! I have the same idea since one year ago, but i was using a mini-ITX as the raspberry, now got a rasp and i'm remaking the project with it. I really appreciate your work, It will help my project to get ended.

### Nice project! I am actually

Nice project! I am actually planning on combining an Arduino and a Raspberry Pi for an autonomous vehicle that I am working on but I am not quite as far along on it as you are with yours. Keep up the good work.

### Thanks for the awesome post!

Thanks for the awesome post! I'm using your method for streaming from my PS Eye on the Raspi with the official 2012-08-16 Raspbian distro but it's using 60-70% CPU for me... any ideas so to why? The only thing I've changed is overclocking to 800Mhz.

### Video settings

It's possibly because the v4l settings need to be set. You need v4l-utils and type:
 v4l2-ctl --list-formats 
Then select 320x240 resolution by typing:
 v4l2-ctl --set-fmt-video=width=320,height=240,pixelformat=0 
Replace the pixelformat with the correct number (I don't have my pi powered on right now to check the exact value). Hope this helps.

### Vivo en Uruguay. Hay algun

Vivo en Uruguay. Hay algun proveedor al que pueda comprar un Raspberry Pi por internet?

### Si, RS Electronics (http:/

Great little project you've done with the Pi :-)

Was reading over on the Foundation forum that you were now doing this with an adhoc wi-fi network. WOuld you mind giving some details on how you managed to do this? I've been struggling with it for about a month.

### A way for "zero" delay?

Hey, im trying the same streaming with a Microsoft Camera on linux, it just works with the same configuration you have in here, but i have a one second delay between the movement and the streamed. Is there a way to perform this?
Thanks

### is there code missing? what

is there code missing? what code goes on the raspi and what is used on the laptop.
Thanks.

### Hi! Thank you for sharing

Hi! Thank you for sharing your setup.

Can you please say what USB wifi dongle you are using? And why is there an antenna connected to a white USB dongle?
Also you are using the "EXTREME 1:10" for your rover?

### Wifi dongle

The wifi dongle doesn't have a brand on it, and I've thrown away the box. All I know is that it uses a Ralink chipset - plenty of other dongles have the same chipset, use those. The TP-Link TL-WN722N also works well.

2nd question: yes.

3rd question: Yes it's a 1:10 radio controlled car.

4th question: yes.

### Thanks! :)

Thanks! :)
I am now testing a PS3 Eye toy webcam.

### tcp server setup

Hi i would like to set up a drone of my own, I am having trouble with the tcp server for the raspberry pi.
Your help would be greatly appreciated.

### Just brilliant!!

Hi, great idea and execution. I have all the parts of my machine figured out but am really struggling writing the tcp stack for the raspberry pi. Any help or a pointer in the right direction would be greatly appreciated.

Cheers, Gavinu

### GStreamer Green screen

Hi amazing stuff here

i followed your instructions and i open the stream in vlc but i am only getting a green screen. do you have any pointers because im stuck

### Which USB hub are you using?

Which USB hub are you using?

### Hey, what kind of latency is

Hey, what kind of latency is there between the ps3 eye and vlc?

### Hello,

Hello,
I am having trouble setting up my wifi. How would I set this up at my school where I need to sign in with a username and a password. How would I set this up using wlan0? It is a WPA-2 network and find an answer online. If you know of a good tutorial, that would be great as well.

Thanks,
Michael
