hamrack-
Yeah, just found that through a thread on yacf, ta.
"We're making good progress. Today the Maximum Power Point Transfer algorithm was implemented - the Igaro D2 knows exactly how much power it can squeeze from your dynamo hub. We're loading it with settings for the SON28 and SON Delux (other hubs tend to be fairly close to these). This was a milestone in Igaro D2's development.
The Igaro D2 has 4 stage phase compensation. You can see how these stages engage at various speeds (roughly kph = hertz/2). These, plus the MPPT technique above allows for up to 10W extraction from a 3W hub. 92-96% of this power makes it's way into the 99% efficient on-board storage or into your USB device.
In parallel we're also testing an Igaro D2 with MLCC arrays. If performance is adequate it will shave 8mm of the casing.
Our next post (target - next Friday) will be a demonstration video of a fully working Igaro D2 charging a Garmin 810. We'll also be showing how the Igaro D2 thwarts the "power lost" message when you're stuck at traffic lights.
Stay tuned!"
I kinda want one now though.

hippy
Anyone with Facebook have details?
Also, if there's no more D1s, what alternatives do I have - Sinewave and?
