X-Tinytrack Project - base concept from TRACKUINO * on ARDUINO

*Thank you  to Javier Martin( *Courtesy from who wrote many of the libraries and codes for the APRS tracker.  I will give him most of the credit of my project .  I design PCB as to be used with the regular HT and GPS module from ARGENT DATA $36 very high sensitive indoor still can fixed GPS data.  I was reading made by Javi and I do not know where I can have PCB so then I build it and then here that I have. Arduino is cheap and easy to develop to get the project going fast.

TRAKUINO code with adding LCD , Softserial Feature(Thank Javier Martin for helping)
Have the Heading in degree , Speed,  and time. Good for small Bicycle Speedometer?

PCB Design base on the *Trackuino Code ( *Courtesy from but have some modification that have to move native serial port to NewSoftserial.h  port , adding GPS connector , Adding LCD and also be able to use the regular HT.  I build PCB just for the min as I want to try out my design and worked . I will redesign again to be able to use . MX-1 (VHF module 144.390 300mW)  email me for the code.

I did write the Code on VB 6 just simple for some HAM who want to use my PCB and did not want to go to Arduino IDE just use GUI to program Callsign, SSID, Symbol connect to this board and PC comm or visual serial port then program to Arduino EPROM. as below:-

1st select Com number then click ok to activate the serial and establish the connection between board and PC then just read from board memory and then edit Write to eprom just simple is that.

I wrote my own code to GPS decode and display on LCD and also included the SMART Beacon reflect to the speed , slow and fast for more freq beacon.

Display Speed , Heading ,  Battery Bar graph level , PST time , LAT , LON 

I also tested out the original Trackuino and it worked pretty good with this unit.  original Trackuino used the Radimetrix MX1 $40 but I have many of my HT so that I used my design to work with HT so that can put in to small metal box somewhere.   Nice project,. I guessed

Completed Unit that I build in Rev.1 LED status in case of no LCD display

Proteus software to design
3D model same as the actual one. 

Geiger Counter + APRS project with Arduino Boot loader

Design the PCB and combined the Geiger Counter with APRS so that when measuring the radiation this unit can send the position via APRS network to appears on Google Maps. I did not write all the code and this have 2 sections of the Code which I combined them together and it worked , it took me many days to test and make sure got the good packet to the IGATE (Aprs server) 

Credit list of people who provided information and has been used in my project:- 
  • Geiger Counter Kit has Code and Calculation by John Giametti here is his web link  
  •  APRS libraries wrote to by Javien Martin -   
  • Softserial and GPS decoder library to elighcash posted sample code so that I can understand how to decode the GPS message on Arduino Playground Forum.  

  • GPS Module from Argent Data $36  very good / high sensitive
    VHF narrow band Radio Module pre programed 144.390 MHz 300mw (150mA only)  from RadioMatrix MX-1 $40 USD
    Combined them together on Demo Board will appear at Amateur Radio Booth,
    Maker Fair 2012 May 19,2012 at San Mateo Fair ground , CA

Just finished and it worked
Completed with SBM-20 and GPS module
