It's been a while, but I have been on a geek holiday to Shenzhen, checking out the factories and markeys etc. Great place, and a recommended geek place to visit.

Before I left, I painted the outside MDF wood surfaces of GIS-Pi in chrome yellow. I went to assemble it, then realised I should really paint the edges and insides as well. I am doing this to help water proof, or moisture proof the prototype unit. MDF does not take too well to water:

I fitted a small 2W loud speaker that I picked up in the SEG market in Shenzhen.

To help reduce the RFI interfering with the GSP external antenna, I fitted an approx. 9cm x 9cm 0.3mm sheet of aluminium to the inside surface of the lid. This brought the error rate down from 11m to a more manageable 3.5m (9 Sat. being used out of 12 sat. in the sky). This still needs more testing, as I haven't tried covering the LCD ribbon cable with aluminium shielding.

With two sets of batteries, GIS-Pi now weighs in at 1516gm! Ouch, that's heavy!

One of these would lighten the load a bit: http://www.computerworld.com/article/2946015/consumerization/a-bigger-faster-google-glass-is-headed-for-the-workplace.html

I think it would be very hand to have a HUD like this showing where where to go and what is or was around the place.

Maybe one day I could afford a set of the 2nd or 3rd generation glasses? :D
