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)

Lady Ada’s Bento Box – Portable Pack & Hack Box [Breadboard + Tin]. Portage for your Projects! Lady Ada’s Bento Box is a crush-proof, drop-proof & water-proof prototyping kit that combines the ultra-rugged Otterbox 3000 with a storage tin and half-size (400-point) breadboard. In the middle is a spot for attaching an Arduino UNO (or any other PCB that has the same shape and mounting holes). There’s plenty of clearance for wires (even ones with plastic bits on the end such as our premium jumper wires or wire bundles) and parts on the breadboard, and the box is so sturdy you never have to worry about any delicate parts inside getting damaged. Toss it in your backpack, suitcase, duffel bag and you can be sure to work on it when you get to school, work or home.

Each pack contains:

• Otterbox 3000
• Half size (400-point) breadboard
• Altoids-sized mint tin
• Laser cut acrylic plate
• Mounting hardware for attaching an Arduino to the plate and sticky foam to attach the tin to the Otterbox

Please note that some of the photos above show the box with an Arduino and/or wires, components, USB cable, displays, etc. These are not included!

Designed with

• Approx 0.85″ clearance for components above the breadboard
