Has anyone used a serial GLCD with arduino before? specifically the sparkfun serial backboard for a 128*64 screen
Searched the internet for a good few hours but cant find any decent example code
my next task is to get 2 arduino boards sending hello to each over over xbee radios

Re: The clock,
Only read the first page guys, that looks really good and I wouldn't mind doing a project like this. But for a newbie, is there any cheaper alternatives to either the materials or completely new project? £145 just for the tubes seems steep.

Of course there's thousands of completely new projects you could complete for far less than a Nixie Clock. You'd probably want to be a bit more specific
As Aod said earlier on in the thread, the cartographer place do some cheap kits that are useful for learning the ropes and practising your soldering skills before you move onto something more complex.

smaller tubes would be cheaper.

Good luck, but you don't really need it, it's an easy build
Yeah, but i'm doing this with one hand.

A kit with the same size tubes as the thread started with is nowhere near £145. It's only once you get to the larger tubes that the price increases that much. I paid about £80 for my IN-8-2 kit with tubes from PV Electronics.

Is there a story behind this? Is it something to do with your username?
Soldato
Wouldn't that blow up if he did?
highly unlikely, Caps only blow if they're really badly mistreated. what's much more likely is that it just won't work

Thinking about making a Serial Arduino... now what's the best way to get a PCB

Plenty of PCB manufactures out there that will do one offs, can only think of these off hand:

Got a load of promo stuff from them at a trade fair. Some rather cool bookmark business cards made from dual sided flexible pcbs!

that's what im going to do too
got an old flatbed scanner off ebay gonna put 2-3 UV tubes in there and use it for photo etching.

Not sure i would use photo-resist, too many variables. Seems the easiest way would be to use a laser printer to print to a transparency, then iron the plastic ink stuff onto the board blank, then use Ferric Chloride to get rid of the copper and wipe off the plastic with something like nail varnish remover. But i would fall down at the first hurdle - i have no way of printing transparencies
This is the one i'm looking at by the way:

If there was a fully featured breadboard layout then i might consider getting a protoboard with it's contacts laid out as they are on a breadboard, but alas... on the plus side i've come across a few interesting ideas with regards to how to make an 'easy' drill press with cheap dremel knock offs.

Dalo pen and ferric chloride always used to be the way to make PCBs when I was a lad. Just be careful with the ferric chloride, it's nasty stuff.

build this with strip board
