Slovikian SIM slots and Soldering

So time is ticking away before I am forced to leave (by my own misguided sense of adventure), to the opposite side of the world to meet my match against giant bugs. The glone Mk2 is looking more and more like it won't get finished before I'm off.

In the mean time I can at least update you and make a record of how far I reached so that I might be able to restart it when I get back.

A couple of major stumbling blocks so far:
The LCD soldering is MASSIVELY fiddly. I would seriously advise anyone who is thinking of doing something similar to ask a friend who does this professionally to give their advice or just do it for them. I think the ideal would actually to use soldering paste from a syringe that is set using a heater. The biggest issue of course is that if I allow the solder or wires to touch more than one connector, it will short the screen. It doesn't help that I can't get the solder to even apply to one of the connectors because, I assume, it is perfectly flat.

Using ribbon cable isn't as trouble solving, so much as trouble causing. It may look nice when it is all said and done, but to have nice neat flat ribbon coming from the box means that all the wires have to be kept together and split when they reach their contacts.

The 3310 does not use a common ground for its buttons as I had initially hoped. It's not even neat. The common grounds (for reference), are:
- up, down, 3
- Select, 2, 5, 8,
- Cancel, 1, 4, 7, *
- 6, 9, #, 0

Madness! Well that's how it looks to an outsider like me, but Nokia aren't the only ones to do this so I guess they must know a reason for this complication. It does leave me with some 36 wires coming from the arm box to the hand box for splitting up. Gah! Somehow this "simplified version" has exploded from innocence to a world of detailed electronics and colour coding of everything to maintain sanity.

The armbox getting a lick of paint. It's going to be metallic when finished.
