So it's nearly midnight on Friday and I'm beat, but I had a productive week. All the other five tricorders have the curved plate installed which was the last external feature to create. Yay beer! And between last night and today nearly the electronics are installed. Yay beer!
The four units not getting the LCD's needed sound boards so I started that by working on the sound file to stretch the length to two minutes and thirty seconds and remove some noise. I really love Magix Audio Cleaning Lab software! The sound I'm using is the MkVII sound and the length lets me use a BigDawg 220 second board which is plenty long.
Here's the board cut down and fitted with a 5 volt regulator. Same as I've done before with the TWOK tricorders.
And the insatllation.
Next came installing the batteries after attaching wires to the connector. The LCD tricorder is on the right.
Following that was building the charge ports and wiring them all together. The LCD versions use another PCB which is a 5 volt supply plus a different speaker installation.
LCD version.
Well at this point I tested the whole package sans the display to see what's what and discovered I have a problem. The pop-up circuit boards are sequencing erratically which never occurred running off just a 9 volt. I tried a couple of the others to make sure it wasn't just the one board. The good news is I think it's just a matter of filtering power supply noise with a capacitor but that's a battle for tomorrow.
