Below are pictures taken while building TinyTrak3 kits with some extra modifications, any questions then please E-mail me at the bottom of the
page. All the pictures will bring up a higher resolution original when clicked
on if you want to see any parts in greater detail.

TinyTrak3 Kit, GPS, upgraded voltage
regulator & connectors |
First I mounted the plug and socket
making sure they would hold the board firm in the case |
Testing box fit before going any further |
Half the TinyTrak components fitted |
TinyTrak3 Built with no voltage
regulator and no microcontroller fitted. |

Photographed from a more exciting angle |
Larger voltage regulator to fit into box |
Heatshrink is used to insulate the
grounded tab of the regulator |
Possible placement of regulator |
Checking depth of the box to make sure
it will fit |
|
|
|
|
|
The regulator pins need some
repositioning and shaping to fit |
2 of 3 pins positioned and shaped |
Pins sharpened to fit into current holes |
Carefully solder the regulator legs to
the PCB |
TT3 ready for GPS connection |
|
|
|
|
|
FET & pull-up resistor for switching and
GPS cable end |
Heatshrink to insulate ground shield |
Positioning FET to contact pins 5 (GND)
and 9 (GPS off) |
Shape leg for ground connection |
Shape gate leg for switching connection |
|
|
|
|
|
Shorten leg so as not to short easily |
Position pull-up resistor from pin 9 to
the 5V MCU supply |
Connect grounds to FET and cover with
heatshrink |
GPS grounding arrangements prepared |
Connect GPS +5V power to 5V rail
supplying PIC MCLR |
|
|
|
|
|
Connect data out from GPS to pin 2 (data
in) |
Chop edge of grommet to fit next to
board |
Positioning of grommet for cable exit |
4.5mm hole drilled in case |
GPS cable leaving box |
