Ski goggle hud

[kelkel60]

Hey Guys,

I'm thinking about building a HUD insert for a pair of ski goggles, similar to this http://hackaday.com/2013/04/05/snowboard-goggle-hud-displays-critical-data-while-falling-down-a-mountain/ , but without using the glasses.
It would consist of small micro-controller ( battery powered) connected up to an accelerometer and a very small (~10mm high) LCD display. The problem i'm having is finding a suitable display. Ideally it would be something like this http://www.syndiant.com/pdfs/SYL2061_ProductBrief.pdf

This chip has a 1024x600 resolution and is only 9mm X 24mm, but the company doesn't seem to supply to single users. Has anyone come across a place that sells a similar chip?

The closest I've found is this: http://au.rs-online.com/web/p/oled-displays/8808584/ but with a resolution of 96 x 16 i don't think it will work.

OLED is a good idea. 96x16 is equivalent to 16 characters by 2 lines (with 7x5 pixel characters). I see plenty of 128x32 pixel OLEDs on ebay (or wherever) that would give you 21 char by 4 lines or fewer bigger characters (say 10 chars double size plus 2 lines of 21 chars, etc.).

You don't need anything nearly as powerful (or power hungry) as a Raspi, instead you can use almost any cheap small microcontroller like a Arduino nano clone. It just needs to parse the serial data stream coming from the GPS module of our choice, and present that information in some meaningful way to the user on your display of choice. It's a relatively simple task. The 128x32 OLEDs are usually based on SSD1306 controller, supported by u8glib on Arduino which makes short work of writing information to the display.

The ebay OLEDs look pretty good, ill check them out. For a micro-controller I was thinking of using a teensy https://www.pjrc.com/teensy/  which I can program with arduino, would it be best to use an accelerometer or a gps for getting the speed?

Look into FLCOS display modules. They have single pixels showing all colors so they look good even when magnified. With an OLED you would see individual subpixels when magnified or looking close.

Maybe you could hack an Epson Moverio? A normal display sitting at a focus distance of a couple of cm won't be very useful for a lot of people.

PS. or a google glass of course.

The hardest is usually not the display but the optics.
