Integrating simple electronics in to 3d pen made stuff.
Vanity Smurf:
I have been playing around making thing with a 3d pen, mostly turning them in to key fobs. the idea struck me that maybe i could put LEDs in them, in the eyes of the Pikachus for example but i know enough about electronics to know that beyond Science kit type toys i know nothing and know even less about what i would need to use to make the idea work. There is conductive PLA filament that i have seen used in simple circuits.
What adavice do you guys have as to what i should do or where i should go to find out what i need to know?
Vanity Smurf:
other stuff i made.

Start with LEDs first.
All that's needed is a battery, a resistor and the LEDs. There doesn't appear to be much space for the battery. Small coin cells could be used, in which case you might be able to avoid the need for a resistor, as the batteries will have a high enough resistance to limit the current to the correct level for the LEDs.

And the conductive PLA is about 30 ohms per CM so that'd help as well.
There's a nice and simple LED tutorial over on Instructables:

The OP does need to be aware that coin cell batteries can be very dangerous if swallowed and the things being printed are likely to be attractive to kids so it needs to be thought about.
Vanity Smurf:
if i understand correctly, i need :-
a soldering iron
lead free solder
button cells
metal clips for the button cells
LEDs
Wires or the conductive filament
and maybe resistors (no idea what ratings on them though)
sorry i have dyspraxia and a little slow on the uptake at times.
