I'll have to keep this short because I have to get to bed as I have work in the morning. However, I just wanted to report that I was able to get sensor readings from Xtrinsic MEMS sensor board to be published to the web browser.   The process is as follows:   Sensor board on Raspberry Pi B+ has a python script that handles communication between the board and the computer. This same python script then pushes the data to the mqtt server which is on the Raspberry Pi 2. This is set over ...
The TrainingSphere is basically a coax drone based on the Raspberry board. There is a very interesting project (Navio+) that is a porting of the ArduPilot software on a Raspberry board. Navio+ software is supposed to be used with their own board, but this board is very expensive and have a lot of features I don't actually need for this project. So I will try to create an APM that uses a different set of sensors specifically designed for indoor use, namely position will be based on the recognit ...

Abstract In "Star wars", a young Luke Skywalker is trained to use the force and sense your enemy. In the training sessions, the enemy is an hovering sphere that randomly fires laser shots. The apprentice Jedi has to intercept the non-lethal laser beams with his light saber. For this challenge, I'd like to build a similar gadget. Reasons The are many reasons why building the hovering sphere is both exciting and challenging autonomous flight is a field I always liked to explore in ...
HELLO EVERYONE!!!!   After many struggles I have managed to get websockets working with mosquitto on my RPi 2 (Thanks element 14 for this baby).   I decided to start from scratch, so I wiped the SD card and reinstalled Raspbian. I honestly had given up on the idea of using websockets, but I couldn't find any recent tutorials that didn't include enabling websockets so I decided to give it one last shot. This particular install tutorial was helpful, although there are number of sites w ...

Abstract So I forgot… Oops! Redesigning a design… again! Updates Making Wheatley What next? Abstract The proposed project has an array of submodules and sub-projects as explained in the first post. Till now I have made a basic RPi Robot and gone into the basics of adding a python GUI to control it. I have also started working with OpenCV on the Raspberry pi and worked with live images. I have also produced a DIY quadcopter and added it to the mix.   So I fo ...
As the 15 inches monitor is carried externally and needs to be set simply and fast to the Meditech box, the top handle has been used designing a couple of rocust and removable parts that - when not in use - can fit in the accessories and components side of the box. The image below shows the 3D milling simulation of the base component; the two ones are identical. The support can be reviewed with a joint to change the monitor orientation (the right side in the image above) with a fixing screw; ...
Introduction  Welcome to Week 5 of the I Ching hexagrams project.  At a last I have the code stable enough to create a video to show what i have achieved.  It might not look that impressive, but I have managed to get (most of) the bugs out of the start-up code so that the display output is reasonably predictable.   What I Have Done So Far  The code that underlies this little video consists of the following elements: Introductory Splash screen based on the sysinfo.py ...
The following images shows the steps of the creation of the Meditech HeartBeat probe  electronics.   Schematics and layout Above: schematics and layout of the probe.

Catch up time

Posted by armour999 Jun 15, 2015
  I was out of commission for a while after a freak accident in the garage. I was moving some boxes and had some heavy iron and lumber crush my left arm and part of my right arm. Nothing broke but it did take some time to heal. So I will be blogging quite abit to catch up. Back in the game       Raspberry Pi camera and Dropbox   I wanted to use the Raspi_Cam_Web_Interface to capture stop motion pictures and videos. But I decided I would like the process to be more a ...
Its been nice outside so I have been flying RC airplanes and coding on my project in the evenings.  There is much software to write so that is the focus right now.       Unfortunately that means my updates are not too exciting.  I can post code but you guys will be bored. Instead, I will post some functionality I am testing that the QuadCOP will need.   As I mentioned I can manually control the quadcopter and then put it in auto fly mode with a switch on my ra ...

Introduction One of the hearth controls is the hearth rate sensor, based or plethysmograph. In our specific case this probe is based on the light transmission so the version is a PPT, or photoplethysmograph. The general principle is to measure a light source transmitted through a human body tissue: the change of the transmitted light varies synchronized with the heart pulses. This probe will be used in conjunction with the blood pressure analysis to take a more complete blood status checking. ...
The past two weeks have consisted of parts placement and trying to fit the circuits and boards into a suitable enclosure. I found a 5.3 x 5.3 x 2.0 inch case to use. This is as close as I could get to the approximate TOS tricorder of 8.0 x 6.0 x 2.0 inch enclosure without actually designing and 3D printing one. I would d have liked to have that ability at this point in the project. Even better would have been to print out the actual shape and colors of the original tricorder from the TV series. ...

Hello, everyone!   Well, I've been struggling to get Mosquitto to play friendly with websockets. Has anyone else tried running Mosquitto with websockets enabled? I posted the following on someone's blog about running the MQTT server on a raspberry pi but it is still "awaiting moderation" so I'm reaching out to this wonderful community for some help! Otherwise, if I can't get it working, I'm just going to stick to the tried-and-true mqtt protocol and pass a text file to lighthttpd. Always h ...
PCB prototyping After a final check the schematic is expected following the previous tests done with wires and breadboards so the final PCB prototype has been milled as shown in the images below. As shown in the final circuit assembled image, only the control components as soldered on the board (mainly the various pull-up resistors). As the board should be fit in the Meditech box and connected to the elements installed at different distances, all the other components are wires with connector ...

Introduction As already explained in the previous posts, the Meditech container includes many components surrounded by a small networks of different and specialized microcomputers and microcontrollers. A ChipKit PI board connected with the RPImaster main device manages a series of independent controls mostly related to the internal Meditech health status; the same micro controller board is also used to set several calibration levels of the probes.   Meditech should be easily controlled and ...
Introduction This is the first article of the second phase of the project development: the implementation of the diagnostic probes. The first implementation described below if the digital microphonic stethoscope based on the usage of the Cirrus Logic Audio Card.     The principle Apparently the technical principle is almost simple. A small condenser microphone should replace the traditional stethoscope earpieces. But - as always occurs - things are not so simple as they seems. The mi ...
Nothing dramatic to post this week, and no pictures again, but I have been debugging Python code to deal with PiFaceCAD interrupts, and progress is a bit slower than I had hoped.  However, i am nearer the point where i can share a fork of some working code on a public repository on GitHub.   I have had the BitScope Micro working with my laptop ready for when i start debugging the comms between the 4D display and the Pi, but despite using it with a new HP laptop that has not yet been o ...
