Hello everybody!   So happy to write this here =) It's been a long time but the idea lives and I've finally come to the point when I'm ready and the things are in the best state possible.   This year, I've been developing a lot. My main project was and still is pyLCI - a headless interface for Raspberry Pi and other Linux boards. It's an external interface you can use on your Raspberry Pi computers to perform any kinds of tasks, such as managing network interfaces (wired&wireless ...
I ended up having to leave my job without getting paid and after working overtime for three weeks. How is that?   As I probably mentioned, it was about creating a system for the so-called "escape rooms". This is an entertainment place where you are paying to go through a series of rooms full of different riddles and tasks which you need to complete in order to get out of the room in the specified time - usually one hour. My job was to make a room fully automated, since all these quests wer ...
Oh well, my keyboard somehow gets stuck so I have to type slamming the keys quite hard and it still doesn't type certain keys sometimes =) I got my i5 laptop fixed - was as easy as ordering the right part off eBay. Unfortunately, it has its quirks. But - it's finally more comfortable to develop web interfaces which is part of my job right now - see, luakit developer console just doesn't work right =( Saves me some time in searching for money for which to buy a used laptop to do my job right.  ...
During these weeks I experienced lot of problems with the Emlid board and the servo controls The servos that move control surfaces were moving not so smoothly and they made a lot of noise and vibrations. I Initially thought that the problem was in the mechanic (leverages not moving smoothly or getting stuck during the movement) After one of the servo started emitting some magic smoke, I started thinking the problem was actually on the PWM signal... So I connected the Bitscope to the PWM outpu ...
Hi again! As you remember from my previous post, I was planning to start my work on this project at the beginning of October. Unfortunately, I cannot make it so - my current job, which requires me to build a control system for Modbus devices, has extended the project's deadline and I am currently doing what I should have been doing 2 weeks ago - helping to plan all the wiring they're making for the whole setup, making some new devices, searching for parts that are missing, and, most importantly, ...
In this post we will face some image processing technique, like blob analysys. I will use the cvBlob library to detect blobs in the image capture by the raspicam   Step1: cvBlob installation 1.       Download cvBlob library from this link                https://github.com/Steelskin/cvblob                   ...

Previous posts for this project: http://www.element14.com/community/community/design-challenges/sci-fi-your-pi/blog/authors/screamingtiger?ICID=BLOG-SciFiPi-challengers   I have been updating my code for the QuadCop in the GitHub.  I am new to Git Hub and many of my changes were not being committed.   https://github.com/screamingtiger/QuadCOP   So for anyone looking at the code it may make more sense now.  The ControlSwitch_32 was very outdated and missing the head c ...
After some busy times, I finally have a weekend for working on this project One of the ancillary parts of this project, is to make some blob analysis on the images captured by RaspiCam to detect laser beams. So I need install the OpenCV libraries and try to get images from RaspiCam inside a C program. The idea is that an external application will command the autopilot subsystem (by means of MAVLink messages) and will detect reflected laser beams to start some special effect So here are the s ...
My QuadCOP is fully repaired.  However there is appears to be one casualty, the Pi-Cam.   I am getting the infamous pi-cam error and all the normal workarounds are failing for me.  When the QuadCop "landed", the little eye/bubble on the head filled with water since it landed in a puddle.  Apparently sound sensors don't detect water real well.  I am not sure if that killed the cam or if the jolt from the ribbon being pulled out did.  I confirmed the ribbon is ok. ...
Introduction The Meditech project is moved to the further step 1. This will produce the formerly testing version of the device; this means a version enabled for testing with volunteers. To move the project and the prototype to the end of this step a series of essential upgrades has been focused playing on the actual version. While Meditech phase zero aimed to reach a full working prototype, despite of the aspect the testing version Meditech phase 1 will be the first full working prototype.   ...
Hello! I'm one of those people who has been selected to participate in this exchange. Unfortunately, my involvement in it was close to zero. I did have a hard time fullfilling my obligations to Element14 community and the participants of this contest. I had external circumstances that made it quite problematic for me to participate, the most important being clinical depression, which I still feel like I'm yet to get rid of even though it's been a year since I started my medication. Unfortunatel ...
This past week finished up the Sci Fi Your Pi Design Challenge, and we saw a mass influx of final project updates being posted. Following the spirit of my Weekly Design Challenge Summary post, I wanted to make a post that would wrap up the Sci Fi Your Pi Design Challenge and showcase some of my favorite projects.     To get started let’s take a quick look at each of the 25 Sci Fi Your Pi projects that captivated our imagination and inspired us over the last several months.  ...

Final writeup

Posted by armour999 Aug 28, 2015
Right to the wire to finish this project. This has been so much fun and a challenge. The software used included Java, C++, Python and Linux. I used several tools including; 1. SD Formatter:  https://www.sdcard.org/downloads/formatter_4/ 2. Win32diskimager: http://sourceforge.net/projects/win32diskimager/files/latest/download 3. FileZilla : https://filezilla-project.org/download.php?type=client Access Point for extending WIFI range   One issue I had was the short range for WiFi ou ...
