|-- Going a bit deeper
This is it after a little unscrewing. Itís just held
together with two screws below the battery holder and some clips
near the top. The slide switch is for the temperature unit setting.
I thought the holes at the front are for a speaker or buzzer
that goes off when the MIN and MAX temps were achieved (so what are
the MIN and MAX temps for anyway?). The thermistor is noticeably
small, that is if you noticed it.
Hereís the LCD screen with the PCB
removed. It wasnít directly connected the PCB so be careful when
opening the thing up.
Hereís the setup. The PCB and the LCD
screen is linked together with that hard-foam like pink with the
black middle thing (I donít know what itís called, so there you
go). Looking at the pink strip, it seems like the black
middle is somehow like a magnet, or a conductive material for the
Pressing the screen on the PCB with the
strip over the copper leads made the display work. Now with this
apparent situation, the screen must be held on the PCB to function. Thatís why the PCB is screwed on the front bezel. At first, I
planned to use the front bezel so I can just screw it back to place
and just cut the bezel up and work from there. But the bezel is ugly
so I decided not to use it (such a shallow reason donít you think?
No modding excitement there). How about a plexi sandwich? With some
thin pieces of acrylic from Home Depot, this is what I came up with.
Some scoring, snapping, drilling,
filing and sanding, some small screws, nuts and washers later and
voila, Plexi sandwich. Donít look at the wrench, or youíll mess up
your sense of size. Itís 1.5 inches long. Cute isnít it. Donít screw
the sandwich in too much. Since the LCD screen is only spaced with
some rubber foam, it can get compressed too much and youíll end up
with a damaged LCD. If you notice a dot on the screen, itís a poke
from the small component at the back from screwing the sandwich too
much. I loosened up the screws enough to keep the LCD screen and the
PCB in place
