How to make a Heating and Cooling Jacket

Step 20 Trouble Shooting

 

• Make sure your connections are working with help from a voltmeter. Test to see where the voltage of your battery has dropped.
   
•  Retry connecting your relay with alligator clips because they are easier to change than threads and wires. This also allows you to find which connections are wrong or broken.
   
• Hooking an L.E.D. up to your relay helps you know when it is turning off or on.

• Make sure you have edited the code to your design. If you have the wrong analog ports written in, your relay will not work.

• DO NOT LET BATTERIES TOUCH! This causes shorts, sparks, smoke, and possibly fire. You should separate them for the two systems. We even went to the extent of covering the leads with felt so they cannot touch anything.

Nice instructable I also had the same idea in my mind for a long time but i didn't know how to do it but now you only have one problem is:What will you do when you want to wash the jacket, will you disassemble it, wash the electronics or water proof the electronics?
You can wash it but without the arduino, batteries and solar cell, I think??

Nice idea, but I think six colored LEDs inside 1/2 pingpong balls is going OTT. I would be installating only two such LEDs: One each on the insides of the wrists. When heating, a) How long does the battery last? b) How much of a draft issue do the fans present? Now you just need the 80s speach synthesiser. "Adjusting, size fit." "Drying. You clothes are now dry."
