As the title indicates, this is my second version of making a LED resin cube. The original version worked well, however there were so many good ideas posted on how to improve it that I decided to make another, (hopefully improved) version.
The main issue that I had with the original was how the batteries were charged. I used a female jack to charge up the batteries. This took away some of the aesthetic of the finished product and definitely wasn’t the best way to charge the batteries. The new one has a charging station and the resin cube is totally enclosed.
In the comment section for the original LED cube, Instructable user - Wesley666 suggested using a “wireless recharging system” which works on induction, the same way that some electric toothbrushes work. I thought this was a great idea and purchased this one which another Instructable user – offtherails2010 suggested.
This version of the resin cube is a little bigger, but the finished product works a treat.
Hope you enjoy.
Here’s a video of it working:
