Interfacing IMU MPU6050 with minibian-raspbian Rpi

Hi, All….

gambar modulnya
wiring diagramnya


ini ada cheap IMU, inertial measurement unit, harganya gak nyampe 200rban, 6axis. dengan komunikasi I2C. worth it lah dengan harga sgitu sih. lets go…

the first thing that u have to do is….RTFM RTFD. read the fu*king manual, read the fuc*ing datasheet.

you can downloat it from here :

and juga register map-nya dari sini :


nanti sambung lagi ya…

Interfacing IMU MPU6050 with minibian-raspbian Rpi

Eth0 not Found!! after cloning raspberry-pi

ERROR: interface eth0 does not exist

you will get this error if you cloned the active-raspberry pi with existing ethernet device,

why this occurred? wkwkwk its pretty easy, when you move the whole system into the new card and new device, your mac-address change right?, this will be ignored by the cloned system and left it unconfigured.

so, to solve this, just remove the persistent rules as follow :

# rm -fr /etc/udev/rules.d/70-persistent-net.rules

and then reboot the system

its suppose to be ok. Sips, tengkyu……..

Audio Stream with Raspberry / nix

Hi, Friend! (remembering OUIJA movie that 2 days ago I watched) hehe


with helping of Darkice and Ice-Cast we’re able to brodcast our mp3 to HTTP stream.

here’s the instruction how to set the darkice and icecast on rasp-pi board :

Download darkice source

First, add the Raspbian source repository if it isn’t already loaded. Add this line to /etc/apt/sources.list

deb-src wheezy main contrib non-free rpi

Update packages and install the darkice dependencies.

$ sudo apt-get update
$ sudo apt-get --no-install-recommends install build-essential devscripts autotools-dev fakeroot dpkg-dev debhelper autotools-dev dh-make quilt ccache libsamplerate0-dev libpulse-dev libaudio-dev lame libjack-jackd2-dev libasound2-dev libtwolame-dev libfaad-dev libflac-dev libmp4v2-dev libshout3-dev libmp3lame-dev

Grab the source package for darkice.

$ mkdir src; cd src/
$ apt-get source darkice

Modify the compilation options to match Raspbian.

$ cd darkice-1.0
$ vi debian/rules

debian/rules should look like this:

#!/usr/bin/make -f

dh $@

.PHONY: override_dh_auto_configure
ln -s /usr/share/misc/config.guess .
ln -s /usr/share/misc/config.sub .
dh_auto_configure — –prefix=/usr –sysconfdir=/usr/share/doc/darkice/examples –with-vorbis-prefix=/usr/lib/arm-linux-gnueabihf/ –with-jack-prefix=/usr/lib/arm-linux-gnueabihf/ –with-alsa-prefix=/usr/lib/arm-linux-gnueabihf/ –with-faac-prefix=/usr/lib/arm-linux-gnueabihf/ –with-aacplus-prefix=/usr/lib/arm-linux-gnueabihf/ –with-samplerate-prefix=/usr/lib/arm-linux-gnueabihf/ –with-lame-prefix=/usr/lib/arm-linux-gnueabihf/ CFLAGS=’-march=armv6 -mfpu=vfp -mfloat-abi=hard’


Beware, ‘make’ wants tabs instead of spaces. To be on the safe side, you can download this rules file instead.

Before you build the new .deb package, change the version to reflect MP3 support:

$ debchange -v 1.0-999~mp3+1

Build and install darkice

Now build and install your custom darkice package.

$ dpkg-buildpackage -rfakeroot -uc -b
$ sudo dpkg -i ../darkice_1.0-999~mp3+1_armhf.deb

Darkice is now installed. To configure it, copy the template config file to /etc.

$ sudo cp /usr/share/doc/darkice/examples/darkice.cfg /etc/

Here’s my sample config file:

# see the darkice.cfg man page for details

# this section describes general aspects of the live streaming session
duration = 0 # duration of encoding, in seconds. 0 means forever
bufferSecs = 5 # size of internal slip buffer, in seconds
reconnect = yes # reconnect to the server(s) if disconnected

# this section describes the audio input that will be streamed
device = plughw:1,0 # Alsa soundcard device for the audio input
sampleRate = 44100 # sample rate in Hz. try 11025, 22050 or 44100
bitsPerSample = 16 # bits per sample. try 16
channel = 1 # channels. 1 = mono, 2 = stereo

# this section describes a streaming connection to an IceCast2 server
# there may be up to 8 of these sections, named [icecast2-0] … [icecast2-7]
# these can be mixed with [icecast-x] and [shoutcast-x] sections
bitrateMode = vbr # variable bit rate
format = mp3 # format of the stream: mp3
quality = 1.0 # quality of the stream sent to the server
bitrate = 256
server = localhost # host name of the server
port = 8000 # port of the IceCast2 server, usually 8000
password = *SOURCE_PASS* # source password to the IceCast2 server
mountPoint = raspi # mount point of this stream on the IceCast2 server
name = RasPi # name of the stream
description = DarkIce on RasPi # description of the stream
url = http://localhost # URL related to the stream
genre = Baby # genre of the stream
public = no # advertise this stream?
localDumpFile = recording.mp3 # Record also to a file

Install icecast2 and begin monitoring

Now you’ll need to install icecast2 to stream the audio over the network.

$ sudo apt-get install icecast2

The installer will ask you for a few passwords, make sure you set the source password as the same one for darkice (*SOURCE_PASS* in the sample config above).

Now start icecast2 and darkice.

$ sudo service icecast2 start
$ sudo darkice

Darkice will run in the foreground (CTRL+C to exit).

Now open up a browser and navigate to http://{Raspberry Pi IP}:8000. Click on m3u and your audio player should play the baby monitor audio. It even works on my Nexus Phone.

Audio Stream with Raspberry / nix

Fast Video Streaming using Webcam and MJPG-Streamer Rasp-Pi

Hello Semua,

kali ini I’d like to show you how to setup streaming with webcam,

after using motion as webcam server, I dont get satisfied its because the lag / latency.


this video streaming’ll be use into my private projects that needed video-streaming.

I found that the MJPG-streamer is the most suitable-non-lag-fast-streaming-video-server ever.


ok, just follow these steps ya :-* (centil banget hehe)

1. Install build dependencies

The following command installs the three libraries that MJPG-Streamer uses:

$ sudo apt-get install libjpeg8-dev imagemagick libv4l-dev

2. Add missing videodev.h

The videodev.h header file that MJPG-Streamer needs has been replaced with a videodev2.h. To make MJPG-Streamer happy you have to create a symbolic link:

$ sudo ln -s /usr/include/linux/videodev2.h /usr/include/linux/videodev.h

3. Download MJPG-Streamer

The source code for MJPG-Streamer is available at, but it is tricky to find the direct download link:

$ wget

4. Unzip the MJPG-Streamer source code

The source code download is a compressed zip file. Put the file in your home directory (or a temporary folder, if you prefer) and run the following to extract the files:

$ unzip

5. Build MJPG-Streamer

MJPG-Streamer comes with several plugins, but only a couple of them are needed to stream video. The command below only builds what’s needed:

$ cd mjpg-streamer-code-182/mjpg-streamer
$ make mjpg_streamer

6. Install MJPG-Streamer

The following commands copy all the needed files into system directories:

$ sudo cp mjpg_streamer /usr/local/bin
$ sudo cp /usr/local/lib/
$ sudo cp -R www /usr/local/www

7. Start the camera

We are almost there. Now it is time to start the camera module:

$ mkdir /tmp/stream
$ mjpg_streamer -i "/usr/local/lib/ -r 320x240 -yuv -f 15" -o "/usr/local/lib/ -w /usr/local/www"


8. Start MJPG-Streamer

The camera is now writing images, so all that is left is to start MJPG-Streamer:

export LD_LIBRARY_PATH=/usr/local/lib/

9. Watch the Stream!

Now you can connect with your web browser and watch the stream live. If you want to watch from within the same Raspberry Pi you can enter http://localhost:8080 in the browser’s address bar. If you want to watch from another computer in your network use http://IP-address:8080.

10. Cleanup

After you verify that everything is working you can remove the source code:

$ cd ../../
$ rm -rf mjpg-streamer-182

happy tryin’

On Goin’ my ‘iseng’ Projects

ok, lebaran telah usai..ehehehe back to work, back to solder, tin and a lot of wires.

1. Arm-Robot 6-DOF / honestly this is my Master Degree Thesis, hehe

the target : there’s an alternative cheap industrial robot, made in Indonesia for sure.

Process : 30%

update :

a. Kinematics Modelling Done

b. Cad Done


2. Near Space Communication and Imaginery

the target : testing my own mini-computer board capability in free-fall area and extreme temperature. I’ll using Airmax for the communication link since its written on the datasheet that its support multiKM communication, all of the payload and communication link would be brought by helium ballon into stratosphere (if you didnt know about this please read wikipedia first.hehe).

Process : 1%


3. Drone-Army

yeah, replace all jets with unmanned air-fighter UAV and Spyin Plane

Process : 80%

update :

a. modelling kit using balsa

b. installing servo

c. testing ground control software

d. flight controller re-design


4. Rocket / Propellant

I started research about this after looking at Lapan Rocket, they using solid KNO3 or Potassium Nitrate + Sugar + Propellant Booster like metal dust. I think Indonesia must be active in research about this sector, not only for defense but also for attack, hehe… Hidup Indonesia Tanah Airku!!

Process : 10 %

update :

a. collecting information for regulation of developing military technology in Indonesia

b. looking for Chemistry Shop, hehe, di bogor banyak inimah.


ok, I’ll update periodically klo ada time, hehe
