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 which only had the tricorder sound play, I incorporated sounds for each of the sensor measurements just to distinguish one from the other. Later in another video demonstration, the following will occur for each sensory measurement:
1. While Temperature and humidity are displaying on the LCD screen, the normal tricorder sound will repeat a two second audio clip as well as during all other measurements.
2. When a flame is detected, an "automatic defense procedures initiated" audio clip will play.
3. When motion is detected, an audio clip of "intruder alert" will play
4. When distance is measured, no audio clip will be heard save the Picorder (original tricorder sound from Sta Trek TOS) sound clip.
5. All measurements and readings, as well as measurement statements will continuously scroll (trying to have continuous graphing display instead) on the LCD screen.
Schematic posting is next.
