Today I ordered a few new parts for my robot project.
4050B DIP-16 Hex Non-Inverting Buffer
These are to be used to level convert between 5 and 3.3 Volts in order to use the Nokia 5110 screen I intend to place either on the robot itself.
The idea to use the 4050 is from http://learn.adafruit.com/nokia-5110-3310-monochrome-lcd I hope this is the right circuit.
Resonator 16.000MHz keramisk 2-pin
The resonators are to be used together with the ATMEGA328 and ATMEGA8 chips order to improve from the internal 8Mhz clock to 16Mhz for the radio-beacons i intend to build for robot navigation.
I have used 16 Mhz crystals before but wanted to try something new. The resonators are a bit less precise, you can read about that here: http://jorisvr.nl/arduino_frequency.html. Main reason for using a resonator you do not need the two capacitors making the circuit a bit easier and they are cheap.
Power supply parts
El.lyt 100uF 50V 85C radialEl.lyt 10uF 50V 85C radial
These are to be used to build power-supplies for the radio-beacons. The circuit is here

Tryckknapp PCB 0.8mm svart
These buttons are intended as reset buttons for the arduino board I built the other day. And perhaps also on the radio beacons.
The RGB-Led is to be used on the robot itself for presenting different states.
Other parts
DIL-hållare 28-pin 0.3" These are to be used together with the atmega chips to avoid destroying the chip when solderingI bought another ATMEGA328-PU DIP-28N Processor 20MHz 32kB chip
I bought a Level converter 3.3V/5V logik also to try out
