I do travel many times a year, sometime I went with family, took relatives, friends, to places in US, for days, may be for weeks, even for a month, when I traveling aboard to visit my family once a year.
Previously, I left my Arduino project(s) untouched for the duration of the traveling. And most of the time, after i got back, I had to start the project over, because I was already forgot where it was left off. During the time of traveling when I got some idea for prototyping, I could not do anything since I did not have Arduino stuffs at hand. And I missed working on the project(s) very much while I was traveling.
This time I planned to do something about it! And this was I prepared them for. A Palm Arduino Kit.
The kit contains:
A DIY palm size Arduino compatible board
A mini breadboard (Commercially available)
A DIY 5V Portable Voltage Regulator (Step 6)
A MOD FTDI cable (See my FTDI adapter instructables details here.)
A MOD 2" Long Antistatic IC Container.
2.25" Wide x 3.75" Long x 1" Hinge Plastic Box (Commercially available)
Whenever I look at 28-pin DIP ATMega328 IC, I always wonder do I have to use it this way all the time, with the pins hang out beside it body. Could I just straighten it out and do something similar to Freeform Arduino? And don't have to use PCB just like the Freeform Arduino, but make it more portable than Freeform Arduino. The other criteria that I use to design this palm Arduino is that it would be small enough to be with some other components to be fit inside 2.25" Wide x 3.75" Long x 1" Hinge Plastic Box.
So the Palm Arduino is born! And I made it to be only 1.5" wide x 2.5" long x 0.5" thick.

And I would like to thank ColorBomb, an Pro Instructables friend, who volunteer to make the schematic in the better format than my had drawn schematic. Thanks for your time and generosity.
