3D Printable illusionist Locket(From the movie The Illusionist)
This is my first attempt in 3D design. Wanted to design this for a very long time.
Support required for both "Left" Part and has to be curve surface down with support. For the other two Flat surface to be on the bed and no support required. No Gluing required. All the joints are snap to fit. Use 1mm Dia X1.5 mm (Max 2mm DiaX2.5 mm) neodymium magnets. I have not fixed magnets as I am waiting to receive them. Make sure polarity of magnet is fixed correctly.
I have seen lot of how to do Ambilight using Raspberry Pi and not one with Orange Pi. This is a long pending project for me. I had an Orange Pi Zero 512 MB that I bought for the same purpose. I had to do more time on research than making it. Making was only a days job. Finding the right component and debugging took a lot of time. The end result of the project is more satisfying and came well than I had expected.

careful choosing the video grabber, first one I bought did not work. Even though I was able to open the video in mplayer v4l2 of hyperion could not detect.
sample of the grabber https://www.amazon.ae/0-2-Meter-Portable-Easier-Cable/dp/B07MW82Z7Z/
Connection of Orange pi Zero and APA 102 LED strips
I had double sided LED strips which was pasted on the edges of the TV Screen. Make sure the TOP and Bottom has same number of LED, similarly right and left has the same number.
Note these numbers. This is used for configuring the LEDs in Hyperion Config(https://hyperion-project.org/wiki/HyperCon-Information).
Connect both ends of +5 and GND together and to the 5V 20A power supply. Current rating depends on the number of LEDs on the screen.
Configuration
HyperCon is the software used for configuring.
Only configurations made are:
LED type selected APA102, color order is changed and SPIdev1.0 given below
"type" : "apa102", "output" : "/dev/spidev1.0",
"colorOrder" : "bgr"
Other change was Enabled grabber-v4l2 and standard manually edited value as "no-change" as given below
"standard" : "no-change",
Other important change I did was to change the configuration of my grabber using v4l2-ctl command
First Install v4l2-ctl
Also change the configuration to write to a file and inspect the file for RGB values if hyperion is able to detect.
I also change the BLACKBORDER detection threshold to 0.2 for better detection.
Started working on the Magic Wand project.
POV. Persistence of vision is used here to create this magic wand.
Letters are created using the controlled switch on and off LEDs.
RFduino now support Linux and installation is straight forward.
Step1: Open terminal in ubuntu by pressing Alt+Ctrl+T
Step2: Type the following commands
cd ~
mkdir Arduino
cd Arduino
wget http://downloads.arduino.cc/arduino-1.6.3-linux64.tar.xz
tar -xf arduino-1.6.3-linux64.tar.xz
sudo apt-get install default-jre
key in password when prompted.
No driver installation required for Ubuntu.
Step3: Open Arduino by typing the following command
cd arduino-1.6.3
./arduino
The current version is 1.6.3. It will be different for different versions.
Step4: Select Menu File->Preference
in the proxy settings change server to rfduino.com and keep other settings as it is and click OK.
in "Additional Board Manager URLs, add "http://rfduino.com/package_rfduino166_index.json" and click OK
Step5: Select Menu Tools->Board->Board Manager and in the window that is opened select RFduino and select install.
It will take a while to download and install files there are 2 set of files one ~ 36MB and other ~52MB
Step6: Select Menu Tools->Board->RFduino
Step7: Select Menu Port->/dev/ttyUSB0
USB menu item will be different in different machine.
Thats it.
Some examples can be found in Menu File->Examples section for RFduino.
The following features make me not a big fan of this OS.
1) The wifi problem.
The wifi reluctant to connect at times when you most need. Need to disconnect and connect many times to get it working. From windows forums got to know that it is the driver issue and they do not have any intention to fix it. The same machine I dual boot for ubuntu which works perfectly.
I have followed some tutorials how to make this work but no success. The Machine I use is Dell inspiron N5050.
2) The Update.
When you just want an urgent mail to send, open the computer then I see this blue screen preparing to configure system do not turn off message. and since my internet do not work It keep on showing 30% for some time then get through after a waiting period. I never know that it has been successful or not.
3) Full screen apps do not work.
I had run in to situation that the full screen apps do not work.I just wanted skype but it was not happening and since there was a problem with internet struggle to update and after updation it started working.
4) Login issue.
The internet is never get success at the time of booting unless i continuously switch the wifi on and off. Hence Authenticating time is more and some times it do not recognise and sign me as guest.
5) Privacy issue.
I had put profile pic of the system by taking a photo suing webcam and shocked to see it was changed my online live account too.
Skype now use the system password. Once changed skype password using the instruction provided and shocked that my machine password was the one i had changed.
The usability and intuitiveness for the OS is minimum. Ubuntu on the other hand it is the prefered OS.
But stuck with windows because some application dependent.
"Windows a Bad OS with good applications, ubuntu Great OS with limited/buggy applications"
