Thank you element14, judges, and all the contestants and members that have made the past 4 months exciting for me and others. Building the Picorder has been very enlightening, a wonderful project and endeavor. So many skills are needed to produce projects of the kind that I've seen here in the community. Many of them learned and some that seem to come naturally to others. Awesome is the single word I can use to describe it! I'm uploading the final documents now and video of the Picorder in a ...
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 design and features (as indicated in the earlier posting yesterday), are intact and functional. I am still tweaking the scripting to permit the device to operate as efficiently as I am able so that its measurements and readings are accomplished ...
This past weekend was fairly intense with picorder activity as indicated by the enclosed photo gallery. Construction continues as I carve out the case by hand for the TFT display complete with four momentary contact switches. We'll soon find out if I can incorporate them to be functional with the scripting, or at the very least to gracefully shutdown the picorder. Sensor array taking shape also with physical placement. So far the flame detector, distance/echo sensor, temperature/humidity sensor ...
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 some extra care to get the required voltage without burning out the amp itself. Final measurement and adjustment has proven positive.   As for the unit itself. Just a brief synopsis of the features and functions. Unlike the original tricorder ...
  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 display. The demo indicates the sensors, switches, some controls and wiring. Schematic to follow. ...

Regarding Charles Gantt's "Design Challenge Summary, Week Ending July 18th" article and the Picorder project progress:   I apologize for the lack of recent pictures of the Picorder to all of element14, challengers, readers and followers. However, previously I wrote that I'm removing the CO2 and alcohol sensors due to their excessive power requirements and replacing them with other types of less power demands which requires redesign of the Picorder. This has been ongoing since that posting. ...
Welcome to crunch time! Since my last posting until day eighty has been, to say the least, challenging. After partially constructing the Picorder in its case, all sorts of unknowns have came to light. I have practically had to throw out all previously conducted testing of hardware and software and start over. That which works in a "black box" environment, rarely functions in the same manner as a complete unit or system. That saying about inventions being 99% perspiration and 1% inspiration holds ...
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. ...
May 23 2015 Day 30 Sound Test I have been working diligently on some of the sound bytes I intend to use and the necessary scripting involved triggering the sound bytes at the appropriate time during sensor reading activity. Scripts will be commented appropriately when modified specifically for the Picorder operation. Final code and documentation will be provided later as the project nears completion.   In the accompanying video sound test, I am using the previously dissembled stereo sp ...

4-26-2015   This weekend I dug into my parts supply and found several sensors which expect to incorporate in the project. They should work out well for they are simple   in design and I have quite a few to choose from. I have some other sensors coming in the mail shortly that I intend to use also, that may prove very interesting in the end.   I've included the pictures of the sensors. I also assembled a Boarduino module that I might determine is useful going forward. Some rough ...
Well, I received my Sci-Fi-your-Pi kit today. Unpacked it and inventory is mostly complete. About four items identified in the Kit list are not there. Now down to business. First order of business is to determine a basic structure and layout design for the project as I want the finished product to appear. The dimensions of the enclosure is going to determine the placement of the specific sensor modules. The sensor placement is of paramount importance to me both for aesthetics and functionality, ...
