IIRC I've seen you answer Qns like this before, but, I don't recall you saying that you don't intend to do anything like that, ever.

I didn't know it was something you're so sensitive about, I'll endeavour not to raise it again, can't promise it'll never happen, but I'll try.
Odd that it's something you'd rule-out as 'never happening', I don't think you're doing yourself a favour with such absolute thinking, but it's your project.
Some combos are completely unrealistic sure, but not necessarily others...

Anyway, I see no point in starting a dedicated KSTOH thread, that must be started by you, & your heart must be in it too.
If it's not then me starting one is a waste of time, as I won't be the one driving it, & there's no one else I'm aware of that would be.

considering parts, labour, shipping, tax, development of other projects, risk and profit;

what would be a fair price for the SolarTOH?

If jolla was not burning somewhere those 80mA it would be priceless for outdoor lovers and i'd buy one if it was somewhere near 100EUR. Just my 2 cents

well I don't know the cost of the parts nor how long itll take to make one...

so I cant really say what price id think would be fair

personally id like it to be less than 100EUR but LOL THIS IS A SOLARTOH!!! you throw ur wallet for something like that! happy to pay the cost

Does it come in black?

White, blue, red, purple, pink, yellow, green, orange, black, alumide

You had me at purple!!!

SolarTOH is open for pre-order

Don't know if after pre-order campaign all colours will still be available. Delivery first half of November, primarily due to waiting on custom panels.

I'm quite possibly the target market for solar charging my phone. I spend days on end away from any power sources sometimes bicycle touring.

I don't think a SolarTOH is very useful to me.

1) it's on the back. My phone is usually facing up, on my bars with mapping running or in a bag keeping dry. It'd not get any charge.

2) I'm always moving so keeping it facing sunlight would be tricky. Also, northern Europe so not exactly guaranteed sunshine.

3) It's too small to generate enough power compared to hub generators or much larger solar panels. I use a hub generator - 6v 3w at average cycling speed which feeds a buffer battery and then delivers USB 5v.

4) You'd have to leave the phone out in the open for hours to charge which generally isn't something you want to do with expensive kit on campsites or whatever.

What I need is a mega efficient transparent solar panel on the front of the phone so you could have it face up and using it.

Hmmm... while it seems awesome for a fishing trip, I wonder about the survivability of the panels, since no cover seems to exist in current model. Are they rugged enough to not have to carry it in a separate container? (extra battery pack would then have advantage of not having to depend on weather) Will they survive normal usage? (I'm probably just paranoid, like when I heard about magnets in OH, for someone growing up with floppies magnets next to electronics seemed like crazy idea)
