AVR with Lemon Power

A Small setup to demonstrate the low power and low voltage operation of AVR Microcontroller, powered by a fruit cell, made of copper and zinc electrodes and 2 lemons only. Tiny13V was used for demonstration with an internal RC oscillator at 128KHz with a divide by 8 fuse setting. LED connected to Pin 2 of the Tiny Micro with a series resistance of 4.7KOhm. Experiment done by Dhananjay Gadre and Anurag Chugh at NSIT

I have the setup going on for the last 5 hours and its still working.

noob, that isnt a fake..

youre a fake!

Read the title dude.. Or description

Attiny13 on a saltwater battery :)

The clock divide by 8 fuse probably isn't necessary. The difference between 16khz and 128khz for power consumption will be insignificant but the extremely slow clock speed would make it difficult to program. With new technology, AVRs (basically a computer on chip) take less then a 555 timer which is an ancient design.

A 555 would work but would probably drain the power much faster.

I presume it would also work on saltwater batteries?

I need to get some attinys to test it.

looool xD nice. try it with apples!

[valiza123]

it's 13v ... goes to 1.8v ;) have it here too.

[polypolyman]

given the title and the circuit (missing the RC circuit a 555 needs), it's an attiny.

[majterstick]

This is AVR microcontroller attiny13.

[microsoftkof]

Is this NE555 timer of oscillator?

If true

The lemon at least 4.5(V) and 3m(A) supply for NE555

[DradusContact911]

Stick a piece of tin and iron into the lemon, hook it up to a circuit and hey presto you have a lemon battery...

Cool!
