Back again with another update. I've uploaded another video capture that shows both the customer front-end and some of the administrative front-end. I am almost done building out the UIs for these and then it is a matter of writing the PHP code to li...
IntroductionDefinitely the Python language with some content improvements has been adopted to manage the UI, replacing the initial idea to use Qt for two reasons: development optimization and architecture simplification. Unfortunately as many times o...
IntroductionMeditech should be something simple. Simple to use, addressed to non-expert IT users, possibly as much autonomous as possible, possibly able to help the operator, possibly usable with few buttons (=NO KEYBOARD REQUIRED) and much more. Thi...
Hello, everyone! I apologize for being incommunicado for so long. I was sick for a few weeks and then I had to wrap up work at the lab for the summer. Excuses, excuses, I know. Anyway, I'm here! I'll be posting a lot more as we are now i...
In my previous post I showed some photos of a frame made of steel wires. I found out this design to be absolutely faulty because it was not rigid enough to dampen vibration induces by motors and propellers. So I started with a new frame frame made of...
The attached file is the current schematic drawing of the 'Picorder'.At this time, no other additions or modifications are expected (unless something drastically fails this late in the contest) to be incorporated into the device. It's basic prototype...
IntroductionOne way to optimize the behavior of the Meditech system is adopting the more reliable tools, programming languages and technologies depending on the different tasks that should be accomplished. This implies obviously a multi-language ...
Just a quick notification that I have nearly completed the Picorder changes and schematic diagram. Both have taken me longer than anticipated. I had some obstacles to overcome with the 1.5vdc power for the speaker amplifier. My voltage divider needed...
This week I was able to make progress on being able to read the recipe files and load the data to the PLC. I also made some modifications to the OEE data collection to add a header line to the log file. PLC Recipe Files:In order to load re...
Hello, Its been awhile since I wrote an update. I have done much work on the quad cop. I ran into some issues with the MEMS sensor board and have abandoned it in favor of another electronic compass. So instead of being negative...
IntroductionThe most common way, and probably better known, to manage a MySQL database is using the PhpMyAdmin web application. This sounds good in all that cases where the MySQL database is remotely stored on a web server, especially when the core c...
IntroductionAs Python is an interpreted language the first temptation for develop applications is directly editing the sources on the Raspberry PI, eventually with the help of the Python idle simple IDE installed by default in raspbian; this developm...
This post is an annex to the Meditech project explaining one of the (possible) best practices to setup an efficient development environment for C++ developing on the Raspberry PI platform with the advantage of an advanced IDE and remote compiling wit...
This week I was able to make progress on a couple of remaining items. First, I was able to get email notifications working and secondly, I was able to get recipes downloaded. I still need to get the recipe data into the PLC, but I should finish that ...
This week I was able to get the DF1 protocol operational. It is not a compete implementation of the protocol, but it implements read and write operations for data transfer to/from a SLC 500 processor.RS-232 communication As mentioned in a previous po...

So here's the video I could not get uploaded over the weekend. I still want to do a couple more videos to show the readouts better for the demo's since the working screen is on the device and is a TFT 2.8R...
IntroductionMeditech will be used in many different environments and not always the visual information provided on the screen maybe useful. Receiving helpful audio hints and suggestions on-the-go is a good solution; when the user should activate a pr...
