Thanks to channel sponsor, PCBWay: https://www.pcbway.com/ This is my second DIY ultrasonic cleaner project. I've taken everything I've learned and put it towards building this leviathan, 42 litre (11 gallon) laundry sink ultrasonic cleaner. Why, you ask? Why not! NOTE: To everyone who has emphasised the importance of placing grommets around the cabling going through the metal chassis, rest assured THIS HAS BEEN DONE, it just doesn't appear in the video. 00:27 Why? 05:07 Soldering transducers 10:04 Gluing the transducers 11:30 About the drivers 14:22 Wiring 14:42 Soldering 19:15 Switches and more wiring 20:53 AC monitor 21:26 Even more wiring 22:24 Testing!
