Re: Mods for the Blink EVSE ! (was Fix)

Sat Apr 09, 2011 11:17 am

Thought I'd add my perspective on this:

The Blink clearly has problems and we know that all EV Project members may be prohibited from cracking the case until the end of their agreement. While previously, I was looking to discard the Blink for a different unit, I'm definitely now looking forward to keeping it and Jan 1st, 2013 :)

I can use Ethernet to get me over the hump until then on the network connectivity side but if the charging unit isn't reliably working for me, I'm definitely going to be complaining loudly. With the mess that this thing is, it's too bad they don't open things up a bit for some community contributions to source. It'd be the fastest road to getting the software side of things fixed at least. Sadly, my Blink has been sitting on my wall dark since 3/30/11. My inspection got signed off on 4/4/11 but I'm still waiting for SDG&E to install the 2nd meter (yes, I've called multiple times)

A couple of side questions:
a) did you find any inappropriately used Open Source? that'd be one way to get them to give up the source.
b) any common antenna connectors that could be easily extended? the fact that they're using powerline adapters when they have a customer with wi-fi problems says tons about their hardware/software expertise

Shh...I'll let you in on something. The mechincal design is flawed that allows you to slip that black ring over the "seal" lock.....oops!

Never mind on b) - just saw the photo in the other thread :)

Given that it's Linux based, they are already violating the GPL if they are not making that source code available to those who have received the hardware. Now - that doesn't necessarily entitle you to do whatever you want with the code that they've written...

Not sure, but I'd bet that one of the many Linux-based-router forums would provide some insight (dd-wrt anyone?).

I've asked for source and no avail. Can everyone here ask for it? They have a requirement to give it out!!!

Just because it's on Linux doesn't necessarily mean they're violating GPL...and doesn't mean that they just have to give it out. Generally, any modified/derivative works, once released to the Public or in commercial use (the Blink certainly qualifies), need to be released but there still isn't solid precedence last time I checked on the whole static vs. dynamic linking issue. There's a dispute here on whether the the later requires release under GPL. There's a small note about it on wikipedia here under Linking and Derived Works - http://en.wikipedia.org/wiki/GNU_General_Public_License.

For anything unmodified, obviously, there's no further release required since it's already released elsewhere

There are several entities who go after corporations who are not complying with open source licenses.... the whole Linksys fiasco was one of the more notable ones (which resulted in DD-WRT). This blog has a good overview for anyone interested. http://www.visionmobile.com/blog/2011/0 ... -copyleft/ - one such entity is http://gpl-violations.org/

At a minimum they need to provide source for all GPL and LGPL binaries.

Binaries that are dynamically linked to GPL libraries do have to have their source released. But most libraries are generally licensed under the LGPL which doesn't have that restriction.

Yes, they do: http://www.gnu.org/licenses/gpl-faq.htm ... JustBinary
