world's deepest dustbin Options

[ranjitha.bm]

want to try and build a trash can similar to the one in video of "The
World's Deepest Bin" from thefuntheory.com. Here is the link to the
video so that you know what I am talking about.
**broken link removed**
does anyone know the circuit diagram or the list of components they
have used like what type of sensors , speakers, battery etc? if anyone
knows please share it guys...

Cool, Bet with some work you could teach it to say thank you!

Looks like a IR or LDR sensor
PC speakers
RC battery
And you would need a voice model or a Solid State MP3 player.

thanks for your help...........i will work on it.

That is an awesome idea! I'm going to have to get some of those in around the city here

I wish you luck, and will be following this thread closely!

How about the solar powered compactors that are in a nearby city to me?

cool solar powered compactors is good one

See: https://www.usatoday.com/money/industries/environment/2009-07-23-philadelphia-solar-trash-cans_N.htm

Then there are the reverse vending machines such as this one: https://www.popsci.com/technology/a...est-ecoatm-cash-dispensing-cellphone-recycler

As for what's required for the trash can. There is a powered speaker set and a battery. Note the hand is waived in front of a sensor just before it is installed in the can.

An ultrasonic ranging module https://www.electro-tech-online.com/custompdfs/2012/01/00597b.pdf comes to mind as well as a PIR motion detector sensor similar to one of those automatic faucets or paper towel dispensors. There are plenty of voice recorder/playback modules available to store the sound.

hi can we use avr335 microcontroller for recording sound and playback???

You can probably use one to control a sound recording module, but I don't believe it is powerful and/or fast enough to record/playback audio directly. You can usually buy very simple sound recorders for cheap--I'd recommend you try that route.

Here is an ap note for just that;

I suggest to google for the ISD25XX series sound recording chips.

They are available for recording times up to 240 seconds at a sampling rate of 8KHz.

If the built in amplifier won't suffice just add a power amplifier.
