Deus_Ex_Machina:
I had already asked for a price on the DOG display. They're over 150€ a piece
Which one?
The DOGS102 white reflective should be less than 10€. Ok, could be too small.
Another option could be this (or different color)
Some of them are claimed to be sunlight readable (see datasheet).
I ordered one of these displays and hope to add support for u8glib soon.
Shipping will cost extra $7. Also production will take 1 week and shipping probably another 2 weeks. At least they did not reached me until now (two weeks since my order was placed).
