Just ordered some electronic-components Value Packs from Futurelec.com!
it cost me about 160 shekels (40$ US +-)
and with these i can finally build most of the things i want to..
although i like scavenging old components, and re-use them, it's not so easy.
it does not mean that my ideas works and products become ungreen, or more polluting, because the main idea is technology for the people, without ruining the planet.
all open source. all DIY. all cheap. all free. all commentable. all self-taught. all community-based.
when the value packs arrive, i can MAKE SUSTAINABLE.
