Backed to Thailand since May 2013

Just let you guy know that I already back to Thailand and working in Thailand now,  It was very hard for me at first to re-adjust back to the life over here than living in San Jose, CA.  Not much time per day for Hobby but I will have to stay late to build my projects.
so many projects still pending that hard to find the time because I have to drive 100 KM round trip to office from my resident out skirt of Bangkok.

Finally become US Citizen

Ceremony at Campbell Theater



With Dave Copper (K6WA)


Building the Geiger Rover -APRS 144.390Mhz


This project that what inspired me to Build the Wall-E or Johnny 5 Robot but it still the long way to go and because I do not have much time to build this robot because I promised the folk of HAM that i will be ready for the Field day and I only have 2 weeks to put everything together.

As you can see the ARM that made of the Flat LCD monitor stand that used for the Supermarket check out and I found it from the Weird Stuffs for $10 and then I put the motor and it seems to serve the purpose to demo that we can use this Robot for Radio Active Survey by using APRS network to broadcast the data via VHF and I-GATE that we can see it from http://aprs.fi/k6xox-8

Snow-Blower is the source of both Rubber Track.  , Power Drive with WheelChair motor 24 VDC small Battery combine for 24VDC that total weight around 70 lbs  RC 5 Ch 2.4Ghz digital mode sometime lossed signal cause the motor to go full-speed. that what I will need to improve in the future.

Field Day 2012 - Foothills Amateur Radio Society (FARS)


This is my last Fieldday for this Club, I have to handover to the New generation to takecard and they will do much better and bigger that me.

Field day 2012 this year was so cold , windy, morning around 47 and night time 41, I stay up all night just want to get the Sat-com contact but too bad , never made any of that :(

Education Demo for Amateur Radio application that can be fun and life saver explain how the APRS combined in the feature for the GEIGER Rover for Radio Active Survey.

Replaced Motor for KENPRO EL rotor from AC Motor to 24 VDC

 All done, under testing. work well, autostop at both end , I added Diode to reversed and also added the Lamp.
 See how bad the motor, Coil already short and never run.
This is what happen when you buy some ROTOR from EBAY I got this for $88 but I send email to complaint them that it won't work and they never tell so they paid me back $40, which ok for the rest of the part should be.  

24 VDC Motor got from EBAY $10 USD

FIt perfectly


Need to Cut the back to get the room from the longer DC motor


Nice but i will need to make the plastic shield to protect the moisure

Maker Fair 2012

Maker Fair 2012 , San Mateo, California on May 19,20 2012

This is the first year that I decided to paticipate this event, I just realized that so many smart young people and many people have a very good idea. I felt that so happy to be around of involve with other people who think the same way I did about creativity to build something better and more fun without any politic or hidden agenda.  well, not all the good people but I try to ignore some of storeo type anyway i am just Asian man and try to have some fun.  I join to be valunteer for this year and I only have small portion to share my idea and time slot was not full fill my dream to tell people about my idea.  Next year, I already setup my motivation to go solo, even it will hard but i will do that with couple of some of my closed friend back me up.

See you guy next year at MAKER FAIR 2013

That 's me at the booth with my Robot

very good meaning

My Robot, Geiger -ROVER
Delorean Hovercraf  very cool

 Electric Car EMW

 One of the battery that used in this car cost $100 per cell from China used around 100 cell

 I like this one Heineken Beer :)


 Mole or Plastic Fabrication company present very implressive model from GAME

My Robot with Geiger Counter APRS , can be send to nuclear danger zone

I believed this the Air Cylinder Robot

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

*Thank you  to Javier Martin( *Courtesy from Trackuino.org) 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 Trackuino.org 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 Trackuino.org) 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.
Feature:-

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.
