Hi, i have been meaning to make some Graphene ever since i saw a video on YouTube about a company called Ion Power Group that collect energy with large antennas. Their antennas were made up of Graphene, graphite and a third substance that slips my mind right now.
I have also seen Laser sabers videos about his homemade Graphene super capacitators.
Anyway, i have seen that the Ultrasonic cleaners are very cheap, and i wondered if you think that these cleaners have the capacity of making Graphene?
Even if it is a small amount, i would like to experiment a little with it.
can you post some links on the Cleaners you are referring to ?
or the applicable tech for Graphene production ?
Thanks
Chet
From personal experience, the cheaper Ultrasonic cleaners are only worthwhile for short term use - they just won't stand up to repeated, long period operation. Also, the cheap ones have built in timer limits (e.g. 30mins) - the Ultrasonic method of making graphene requires hours - therefore you have to babysit the process making sure to turn the timer back on. Alternatively - and this is what I did - was to take it apart (voiding the warranty!) and wire the timer relay switch so it's always on. I then used a wall plug digital timer to set the hours of operation so that it did not require babysitting. The timer limits are probably in part due to the inherit device limitations (as a consequence of price) and so it was not surprising it didn't last long. Of course your mileage on cheap models may vary :)
I attempted to replace the transducer (which is what failed) but on the model I had it is glued on and I couldn't find a way to get it off without damaging the container.
Depending on how much graphene you intend to make, you don't need a large model either - I got a 1.75 litre model that was just the right size for a preserving jar to put the solution in. Of course the larger capacity models cost more.
If I was going to buy another Ultrasonic cleaner it would be something like the following - more expensive but higher quality and built for long period operation (no timer limits!):

Good luck on your quest :D
