How to build a thermoelectric lamp

Step 15 Solder and fit the joule thief

You can remove the battery pack from the emergency charger and just use the plastic end cap with the circuit in it.

First check the polarity of the wires to make sure that you know which way to solder them on. You can do this by just trying them both ways to see which way works, do this with the peltier heated by the candle. You'll need to solder the wires on to the joule thief and attach the joule thief to the tin can. I just used hot melt glue to fix it in place. You should have a nice 2.5mm output jack where you can plug things in.

I added an extra photo in step 15 for you, though I can't tell you exactly how to wire your peltier up because the polarity varies depending on which side of the peltier you are heating, you have to test it either both ways or with a multimeter.
