$30.00 ???
I'm glad I was sitting... I know things cost more depending on where you live, but this surprised me... I don't know what you have available for buying components there but they are nowhere near that much here, buying from an "expensive" distributor (Digikey). Here's a link for red 5mm TH parts: http://search.digikey.com/scripts/Dk...me=160-1678-ND. As you can see 100 pcs. is $8.60USD ($9.60AUD)A comparable SMD (http://search.digikey.com/scripts/Dk...=160-1463-1-ND) is $13.00/100. This is a 1210 package; I don't know that I'd go smaller than that. Again, for beginners SMD would be hard enough to solder, let alone smaller. Smaller devices "typically" don't have a round lens as well.
The "joystick" buttons are not a problem. I didn't see how many pins are used on the uC. How about a couple of pads for a rolling ball tilt switch (one pin on the uC)? These are about $1.50 here (so that'd be $6.00 there)If you tilt the board 90 degrees the joystick pad (and display) can "rearrange" to the correct orientation?
Resonators with built in caps are cheaper (about $0.60) than a crystal.
It looks like any NPN will do. 2N5210 parts are about $0.15USD. For whatever reason, "BC" parts are slightly more than "2N" parts here.
I'll start drawing the schematic... I have a fresh martini in front of me so I'll be on cruise control... the package type can wait until more people have weighed in...
