Mark and I have been working on a professional and robust software/hardware platform to facilitate further development on Fuzzylogic's Roadster Charge Monitor.
As it's based on Fuzzylogic's RCM project, anyone can make their own hardware. If there is enough interest though, a professionally manufactured SMT based PCB and a quad-band GSM module will be offered at $99/set. Since Mark and I are both in this for the interest of further development, all proceeds minus cost go directly to the Hong Kong SPCA.
