Angelo, great project and super video. I knew how it worked, but making one looked very formidable until I saw your work. When I make mine I will link my website back to yours to give you the credit you deserve! BTW, I live on the East Coast and I found in someone's garbage a large (Droid-size) plastic float for lobster fishing! Perfect, and I think they are quite cheap in the store if you live in an ocean-front community. If it's too thick though I'll make my body out of fiberglass as you were going to do.

Hello, your saltwater battery flashlight is very awesome! I really like the way you construct it. I hope you can post some more instructables on green energy, and also LED projects.

By the way, I'm so shocked to see your picture! We seem to be twins, just kidding(but nearly true, haha).

hi, i really liked your water powered flash light, i have a question about the power cell , copper strip and the zinc strip do they touch each other, before the water is poured in the pipe , can i use copper wire & aluminium wire instead of zinc strip (is there any weight or length something like that ?) for the power cell to work.

I made the Altoid tin mic circuit, and can hear my voice very faintly behind an extremely loud gargling sound, don't know if it matters, but i replaced the potentiometer with a little blue one that came with my arduino... Do you have any suggestions??

hi i have just seen your project for your bluetooth speaker boombox and i think it;s brilliant what you have done so i was thinking of building on myself and was looking a your wiring diagram and was wondering instead of using the amp you built for the woofer could you just use another digital amp you used with the other speakers and if so do you need the resistors on that line if you could let me know i would be grateful

Hey, Angelo, I need help with the testing part, I want to test how much electricity is generated by only one piezo disc. Do I still need the Mylar capacitor? And how do I connect the piezo disc to the Mylar capacitor then to the digital multimeter?

If you need to send me an Email, then send it to:

do you know if it is possible to use an lm4871 instead of the 8002B ic for the DIY Supercharged Bluetooth Speaker (v2.0) project?

As far as I can recall, they're both the same.

What camera/lighting do you use? I really like your photos.

I'm using my Nikon D5300 with a 17-55 f/2.8 lens. As for the lighting, I'm just using a simple desk lamp.
