Tricorder

Star Trek TNG Tricorder

  So, yes, I'm a Trekkie.  I didn't grow up during the TOS series, instead, it was the ST:TNG period. With that useless knowledge, I have a few TNG toys and even though they are great collectors items, I want to make them more detailed like they are on screen.  With lots of LEDs, buttons, and even a working LCD screen. 

 Update: August 11th, 2019

  I have been gathering parts and components to get this project going and my apologies for updates being so few and far between.

  The Tricorder itself you can get on Ebay pretty cheap since they manufactured a ton of these.  Think I paid around $15 for mine.  They are cheaply made with very little circuitry.  It has 2 LEDs, a tiny speaker, couple of C9013 PNPs, couple of resistors, and of course the black blob that is "Chip on Board."

  The most difficult aspect is going to be the LCD.  I purchased a Chinese MP3/MP4 player ($12 on Ebay) will try and hack it enough to play videos with a few buttons.  The player has the default tactile buttons for control.  I will be using regular panel buttons on the Tricorder body so I will need to add wires to the button circuit so we can have control of play back. 

  Refer to the image and you can see how I soldered a ribbon cable to the button pads of the mp4 player.  This will alow me to place regular momentary buttons anywhere on the case to control the player.

Made some progress on the tricorder, It's not much but it's something.  I started breadboarding the circuit and added the LCD.  Like I said, it's not much but it's progress none-the-less.  The LEDs are controlled by a TLC5940 with a generic code.  Still have some work to do before going to the next step which would be adding more LEDs and also having the ATmega controlling the LCD screen directly.
