My kid's bubble blowing machine runs on 8 AA batteries which it chews through in less than an hour. Also, only the first 15 minutes seem to make a satisfying amount of bubbles and after that, it fades to only a few bubbles every now and then.
I have carefully wired it to a 12V DC adapter and have housed all connections so they're water-tight.
When I initially tested this setup by holding the AC wires to the motor, all seemed to work well and fine. However, now that it's all soldered up, it pulses with intermittent bursts of power.
How do I fix this? Do I require a voltage regulator? If so, can it be applied anywhere down the power line?
Please know I am completely novice when it comes to the nuances of electrical engineering, so if possible, keep it layman. Thanks!
Thank you all for your replies. I am still trying to learn the ropes here at SE but I'd like to upvote all of your replies. Apparently I cannot yet.
From what I collect from my answers, I need a DC power supply that exceeds 1 Amp. I thought that anything that plugged into a wall was AC.
Here is a photo of the info from the adapter I have connected:
It says that it's 1.5A. Is this not sufficient? It does not indicate 12VDC. Is this my problem?
If I need a 12VDC adapter that outputs 2A and I was to purchase one, can I simply splice it in at an earlier stage than having to take the whole toy apart again and rewire throughout? Will the wires from this adapter, in other words, handle the throughput of the new adapter?
Thanks so much again everyone.
