Intro: Easy Mintyheater

Step 1:

Step 2:

Step 3:

Step 4:

Step 5: Parts

: mint tin
: toggle switch
: 9volt battery adapter
: pen spring
: hot glue gun
: soldering iron
: drill
: plyers ( long nose work best )

Step 6: Assembly

First get your pen spring and solder two 20cm pieces of wire to the springs ends. Then wire one ends to the switch and solder now solder one end of the battery connector to the switch then solder. Now solder the remaining two wires together and glue the wires and battery connector down I used bluetack but glue is fine an I also didn't solder I threaded the wires through ether way is fine you will also need to drill a hole for the switch and then tighten with a pair of pliers and get heating

Step 7: How It Works

This easy project works by shorting out the battery and this in turn makes heat from the spring and battery just close the lid for optimum proformance so the warm air stays In perfect for warming hands

Step 8: It Is Not My Fault If You Get Hurt

I will take no responsibility if anyone gets hurt build this at your own risk not my fault

    Also the risks are that the battery might get too hot and the electrical currant may conduct through the case I would but a rubber layer over the sides of the casing or any material that doesn't conduct this would reduce any risk of shock

    If you use a longer the spring the shorting point will be smaller therefore reducing the heat but a weak resistor could help but may be hard to control the heat and power output

    I also might have a longer spring. I wonder if that might get more heat (or dispense heat differently).

    Thx. I wonder if putting some weak resistor in the circuit could both extend the battery life a little and reduce some risks. BTW, besides maybe hard to control heat, what are the other risks involved?

    You can get heat for about 30 mins off a half used battery but it is entirely up to the charge of the batter

    About how long do you get heat? I have a bunch of half-dead 9-volts and this seems like a nice way to get some use out of them before they go to the battery recycling place.

    Thanks I just edited so I don't get blamed thanks for the tip my first instructable so I was so worried how people would react

    Nice idea, but I would put a disclaimer in their, letting people know its not your fault if they get hurt. Shorting the battery like that could possible cause problems. Just better safe than sorry ;)
