It seems to me the Arduino open-source electronics prototyping platform is a perfect match for PortableApps, but I was surprised that it has not been ported. I have downloaded the stuff to start working on it, but I don't have as much free time as I used to, and I hoped someone else could do this faster than me.
- Arduino is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. It's intended for artists, designers, hobbyists, and anyone interested in creating interactive objects or environments.
The software is available for Mac OS, Windows, and Linux at http://www.arduino.cc/en/Main/Software — it doesn't require installation but just unzip and run so it shouldn't be too hard to convert.
