[Fmilburn] was having fun with his grandkids, playing around with a small Radio Shack solar panel, some supercapacitors and a Zener diode when the kids eventually moved on to blowing bubbles with their grandmother. To regain their interest he got an inexpensive battery powered, soap Bubble Blaster and converted it to run on the solar panel and supercapacitors instead.

His write-up is a pretty fun read, walking through his process, including an oscilloscope measurement showing how the capacitors’ voltage drops from 5.26 V to 3.5 V when the trigger is pressed, and interestingly, slowly recovers until it’s released a second …read more

The next day [Over_Engineered_2] posted a video of his working one.

We often hear that you need precision CAD software such as Solidworks and AutoCAD to design a functional machine but the animation was done using Cinema 4D, used for films such as Iron Man 3 and …read more
