Introduction: DIY - Magnetic Connectors
Batteries are the only reliable and affordable source of DC supply for small scale DIY projects. However, for using the batteries we require good quality battery holders. Some of the battery holders are quite affordable whereas some are way out of range for a hobby project.
Note: I was inspired to make these connectors after watching this instructable from Matlek (https://www.instructables.com/id/Magnetic-Connecto...). I have no idea if he actually invented these but i learned to make these from his instructable.
So, i decided to make an instructable which is short, has only necessary details and also material links for those who actually need to make some of these at home.
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Watch the Video
As i always say, a video is a great tool that provides deep insight into the understanding of the procedure and makes the process simple to follow. However, also visit next steps for additional details and images.
Step 2: Order Parts
- Neodymium Magnets - https://rover.ebay.com/rover/1/711-53200-19255-0/1...
- Hot Glue Gun - https://rover.ebay.com/rover/1/711-53200-19255-0/...
From Home & Local Store: small PVC Pipe (1/2" diameter) and connecting wires.
Step 3: Let's Begin
- Place 2 magnets on a flat surface.
- Strip the wire and evenly spread the wire strands.
- Place the wire strands over one of the magnet and place another magnet over them such that the wires are sandwiched between both the magnets.
- Similarly, repeat the steps for the other pair of magnets.
Note: Make sure to refer to the images above and the video.
Step 4: Seal the Magnets
- Cut two small pieces from a PVC pipe.
- Place the magnets over the metal or a glass surface.
- Also, place the small PVC pieces around the magnets, such that the magnets are in center of the PVC.
- Pull the wire above and fill the PVC cylinders with hot glue (video for reference).
- Let the hot glue dry for sometime.
Step 5: Test the Connectors
- After the glue has dried completely, carefully separate the magnetic connectors from the surface.
- Connect a motor or any other apparatus to the wires.
- Take a Li-ion battery and stick the connectors to the battery terminals.
- The neodymium magnets firmly stick to the battery terminals and provide a good point of contact.
Note: I made this magnetic connectors mostly to be used with 18650 Li-ion cells, however, just by varying the size of magnets, these connector can be made for almost any type of batteries that have magnetic terminals.
So Friends, this here concludes the instructable, stay tuned and SUBSCRIBE to receive regular updates. In case, you might have missed watch the video and see how i made these extremely useful magnetic connectors at home.
Thanks for your Support...!!
