you may or may not add a resister but I would have if I would have had one. this instructable was made in a hurry and with an android phone. Feel free...
this is a led resin block I decided to make from things I found in my room I used the following: epoxy resin from hobby lobby led light up mug tilt activated wire solder usb charger and a usb female port matching the charger resisters would be advised but u didn't use any I recommend doing so
like I said in the introduction the epoxy can be found at hobby lobby the mug may be harder to find I would do some Google searches to find a suitable mug but the solder and wire shouldn't be hard to find
Step 2: Adding Usb
I wanted to make this as non-wasteful as possible so I went with using a usb
Step 3: Encasing in resin
I used a Hershey's cocoa tin that is plastic but you are welcome to do what you would like.
Step 4: Enjoy!
