My Playmate tricorder

OK, I have to admit that my first Playmates Tricorder built with Gerry Mros's circuit is gone now. It won't even come back to me (even if it did, it would not be in a very good state). This will teach me a lesson not to be too forward in helping friends even with good intentions. They will always take it for granted, and lose them as well.

Damn. That Tricorder took me years to search for it and also I had to save up to buy the circuit boards. And now its gone because someone does not appreciate things in their care. Luckily, I have taken back most of my props for display there.

I am so pissed about it. And its missing for months with no news. So, its time to let go.

And then, one day, I found the other Tricorder, which was my very first prototype. Looking back at it, brought me a lot of sadness. Not because of its condition but on how I approached it. For you see, I want it to be the "best" Tricorder and in my fanatical quest, I overlooked many things, mainly the KISS (Keep It Simple, Stupid) method and also to challenge myself with new technology.....

So, now I am starting to try with this Tricorder again. And hopefully, after so many lessons, I will get my Tricorder working again. But it will be at least tow years away unless someone pays me lots to stay at home and do stuff like these. Ha ha ha ha

In front, it looks OK, but once you open the covers...

You can start to see when I went wrong. For example, using a two-part
epoxy for the LEDs which now has turned brown. The strong magnet has
pried itself loose and is rusting somewhere.

This is the part which is the most embarassing. Because of the
"natural" battery holder, I refused to think about other source
of batteries and went on to try reduce the voltage to fit the 2AA
batteries and not the other way round. And if I used those SMT
LEDs and a thinner PCB, it would have solved my problems

This is one thing I hate about clear resins, plastic and epoxies
because over here, as time goes by, they will turn brown or
worse. even the gray plastic is turning brown too
