In this instructable I will be showing you how to make your very own personal heater for when you're outside and it's freezing cold! All you need to do is add batteries and you have over 100 F in the palm of your hands, or pocket, etc. BUT REMEMBER TO WEAR GLOVES OR MAKE SURE THAT YOUR POCKETS WON'T BURN!!!
** I AM NOT ACCOUNTABLE FOR YOUR ACTIONS WHETHER YOU BURN/HARM/HURT YOURSELF OR SOMEONE ELSE, THIS WILL BE YOUR FAULT, NOT MINE **
This heater is easy to do and cheap to buy the materials. BTW: all the materials can be found at Radio Shack. This is where I went to get the materials and they had everything I needed. However, there may not be a Radio Shack near you so just try a hardware store or hobby shop.
Step 1: Materials
What you will need for this project are the following:
- 28-30 Gauge Wrapping Wire (at least 30 feet)
- Twin AA - Battery Holder
- 2 AA Batteries
- Hot Glue Gun
- Soldering Iron
- A Small Piece of Balsa Wood the size of the Twin AA - Battery Holder
Step 2: Wrap the wrapping wire
Now wrap 30 feet of your 28-30 gauge wrapping wire around the piece of balsa wood the size of the twin AA battery holder. Leave about 1 centimeter from both sides of the balsa wood to apply hot glue later on. Also, make sure that both ends of the wire are sticking out so they can be easily soldered (you will need to trim back the covering on the wire for it to solder).
Step 3: Soldering time
Now take your two ends from your wrapping wire and solder them to the two wires coming out of the battery holder. Almost done, one more step to go!
Step 4: Finally, the last step!
Now just take your piece of balsa wood and apply a small dot of hot glue to both sides of the wrapping wire (without touching the wire of course). Then just take your battery holder and press it onto the hot glue until it settles and you're done! Just place your batteries in and it already starts to heat up!
This is great for the winter and especially when you're outside with all that snow around you, and you can just keep it in your hands (preferrably with gloves on) or keep it in your pocket! With the two AA batteries, it can run for a good 45 minutes at a great hot temperature (not exactly sure how hot but it's over 100 degrees Fahrenheit!)!
