[Wendy] asked a very good question. Could putting liquid resin into an ultrasonic cleaner help degas it? Would it help remove bubbles, resulting in a cleaner pour and nicer end …read more Continue reading Fail of the Week: Can an Ultrasonic Cleaner Remove Bubbles From Resin?
This is the time of year when people in the Northern Hemisphere like to enjoy hot beverages like hot chocolate. [The Action Lab] uses hot chocolate to demonstrate an odd …read more Continue reading The Hot Chocolate Effect Explained
Sodastream machines are a fun way to turn tap water into carbonated water. However, the canisters are expensive and generally require a trip to the store to get a replacement. …read more Continue reading Cheaper Sodastream With A Big CO2 Tank Is A Semi-Dangerous Way to Save
Everyone loves a good bubble machine. These oddly satisfying novelty items have brought children and adults mindless entertainment since their inception. [8BitsAndAByte] had the same thought, but wanted to give their bubble machine a taste of the IoT-age.
First, they modified an off-the-shelf bubble machine with a Raspberry Pi and …read more
Despite the title, this isn’t a tale of conversing with Michael Jackson’s chimp. Rather, it is about [KyungYun]’s machine that transforms speech into whimsical bubbles. While the speech control is novel, we were more fascinated with how the mechanism uses a system of strings to blow bubbles, along with the workmanship to make the device portable.
The rate of fire isn’t that great, so the bubbles appear to simply get larger the longer you talk. Essentially, the device increases the size of the iris — the part that blows the bubble — until you pause speaking. Then it burps out …read more
[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

If you ever wanted to make an occasion festive with bubbles, [Sandeep_UNO] may have the project for you. As you can see in the video below (and, yes, it should have the phone rotated and it doesn’t), his Arduino uses a servo motor to dip a bubble wand into soap solution and then pulls it in front of a fan. The entire operation repeats over and over again.
There’s not a lot of detail and no code that we could find, but honestly, if you know how to drive a servo motor from an Arduino, the rest is pretty easy …read more
