I just read a news article about the Open Dots charging technology: Link, in german. More Information you get on the website of the Open Dots Alliance: http://opendotsalliance.org/

In a few words: Open Dots is a wireless charging technology working with direct contact, not inductive like Qi. The idea is that the device lies on a charging pad and is charging, no matter how you place it on the pad. It is realised by four Pins on the back of the device with a specified arrangement and contact fields on the charging pad.

According to the Information in the news article and on the website, the Open Dots alliance is working together with car manufacturers, which are planning to implement this technology in a few of their upcoming models. The best thing is, that the specification is completely open and free to use.

I think this technology fits perfect with the TOH concept and the openness of the technology fits perfect with the philosophy of Jolla. So I suggest that Jolla (or a third party developer) develops an "Open Dots The Other Half" and additionally a charging pad for home use :-).

I like it's description: Zero risk of cancer! It can be a good solution anyway, but I get sarcastic from marketing $hits like this.

Good idea.

I don't get it why it uses 15-19V and then regulate it to 5V with a switching regulator. I assume they want it to be used for other than cellphones, but today 5V is almost standard. Also it mentions car manufacturers but cars have 12V batteries.

I don't think 5V is required by the standard. If the phone supports charging with higher voltage I don't think anything prevents using higher voltage. "For many applications, such as for cell phones, the rectifier output is dropped to 5V with a switching regulator."
