Cars That Think

So, I set about building an open-source ice tracker from DIY components that not only proved to be much, much cheaper but also much more capable than the commercial options.

Technically the SAE specification calls for 890 ohms, but that radio store was out of 890 ohms and 1k-ohm appears to do the trick. If you pull that pin down to +6v, the charger will fire up. So I wired in a 50v diode with a resistor to ground (remember that extra lead). It says I pulled 3.51 Pin 4 -->| --[1kw] - Pin 3 (Ground).

volts for about 60 hours. For capacitors, voltage translates to electrons stored —the voltage drop across a capacitor is proportional to its total charge.) In the future, DIY may not even be necessary. Kinefox is open source, with files published on GitHub.

Also, besides giving you the ability to charge at night when most utility rates are lower, future vehicle-to-grid (V2G) technology may allow you to sell some of your stored energy back to the utilities. Currently, there are some industrial facilities that use battery swapping to replenish the energy stores of electric forklifts.
