Bill of materials (for one pendant-- double this for a pair of earrings):

• Gemma M0 or Original Gemma (M0 type is recommended!)
• NeoPixel ring
• tiny lipoly battery with charger
• pendant hanger or ear wires/jump rings
• stranded wire
• clear thread
• double stick tape
• E6000 adhesive (if using glue-on pendant hanger)

Any entry level 'all-in-one' soldering iron that you might find at your local hardware store should work. As with most things in life, you get what you pay for.
Upgrading to a higher end soldering iron setup, like the Hakko FX-888 that we stock in our store, will make soldering fun and easy.

Do not use a "ColdHeat" soldering iron! They are not suitable for delicate electronics work and can damage the boards (see here).

Sharp scissors are a must!

Don't forget your wire strippers, pliers, and flush snips! Tweezers can help manipulate the wires connecting components in your circuit.

Use needles to secure threads to the circuit.
