Ultrasonic cleaners are gaining popularity these days because they provide the best cleaning mechanism and also involve a hassle free cleaning process. However, there are many of us who can’t afford an ultrasonic cleaner as it is quite expensive and isn’t used regularly. In case you are one of them, we present to you a complete do it yourself guide to build your own ultrasonic cleaner. All you need to do is have some knowledge of physics and some experience in assembling and dissembling hardware parts. Even though, your ultrasonic cleaner won’t be any match to the ones purchased from the market, it will serve its purpose of cleaning minute and unreachable parts.
The basic materials that you require to build your own ultrasonic machine is an oscilloscope, ultrasonic transducers, line amplifier, a decent sound card, a steel container, a few audio cables for connecting and a soldering iron. You should have in mind that any container won’t serve the purpose as we need very thin steel layer preferably something like a cookie tray. An ultrasonic generator is a very good alternative if you don’t have a linear amplifier and a sound card. But, the cost of an ultrasonic generator could hurt your pocket as you are building your own ultrasonic cleaner to cut down the cost. Also, the ultrasonic generator can drive only one transducer, which is another disadvantage of using it.
Before you buy your transducers, make sure that they are specifically designed for ultrasonic cleaners. Transducers having a power of 55 watts could be a very good choice. These transducers can be purchased from any of the reliable online stores that sell electronic components. The oscilloscope used in the ultrasonic cleaners do nothing but measure the frequency of the sound waves. In case you aren’t interested in any technical values, but only care about effective cleaning, then you can drop out the oscilloscope.
Before you buy all the components, make sure that they have the capacity to work together at a particular frequency as you don’t want your effort to go in vain. This can be done by calculating the frequency response of the sound card and then check it with the frequency specifications of the other devices such as the ultrasonic transducers and the oscilloscope. One thing that you should keep in mind is that the RMS power of the line amplifier should be greater than that of the ultrasonic transducers to get the best results.
Once you collect all the basic material, the process of assembling them isn’t very troublesome. To begin with you should place the transducers on the diagonally opposite ends of the steel tank, in such a way that there is almost no distance between the transducer and the walls of the tank. Next you need to cut down the ends of the audio cable and then solder one of its ends to the pad. The other end of the wire needs to be connected to the output of the amplifier. Finally, the sound card has to be connected to the input terminals of the amplifier to complete the ultrasonic cleaner.
You can start using the cleaner by pouring in some cleaning solution and plugging in to a power source. However, keep in mind that this ultrasonic cleaner might not show best results as it isn’t tested properly. Nevertheless, it will be effective in cleaning minute particles with ease.
