bufff living on the edge. the clock is always tick tack and the boards came on my last day in portugal:) but I still had time to assemble 2 boards with tiago in lisbon hehehe
the job is perfect and clean although they forgot to print the silkscreen layers.. this boards came from the other side of the planet swimming trough sharks and skipping santa-claus-snail-mail-traffic. we asked seeedstudio.com to make them. it cost us 89$ plus 33$ shipping to portugal. 122$/ by 10 boards “on vacation” and 10 “on the sofa” gives a 6.1$ each board. nice price since it was a very ultra-low-small production.
here it goes the local-sustainable-environmentally-friendly-talk of the refarm speach :( and wait until you see the list of countries where the components are made.. there falls the local talk also..
but on the “safety” side of the materials used on this boards there is only one component that we still didn’t find a Rohs compliance version and that is the LDR (Photo Light Dependent Resistor) everything else is “green”
well green is what they call it but is more a greenish-brownzing.. the RoHS directive, stablished by the european union, calls for the near elimination of 6 chemical substances used in most electronics and electronic equipment: Lead(Pb), Mercury (Hg), Cadmium (Cd), Hexavalent chromium (Cr6+), Polybrominated biphenyls (PBB) and Polybrominated diphenyl ether (PBDE). despise all the components that we are using in this project are at least “RoHS compliant” we still have a scarecrow that would damage the environment and ourselves if not correctly disposal upon is end of life. and you know how are the objects, they don’t last forever but some of their raw material do. take mercury for example: it crosses all the food chain and rests on the top. by the way is you , your neurons, your cells, your friends, your mother and her grandson.. there is something in the word ecosystem..
