every time I see a lemon pig my first reaction is "that's not how you put the pennies to make a battery! You need a galvanized nail too!"Will one of you please make a self-powered pig with light up eyes?

You might need to put like four pigs in parallel. You could make the tail with a bit of zinc and join them together...

@futurebird “Will one of you please make a self-powered pig with light up eyes?”Things you’ll only see on Mastodon, part 94… 😆

@futurebird I had never seen one and didn’t understand what you were talking about until I saw this post.The one on the left looks as if it had foil on the tail. If this pierces the skin and touches the electrolyte, I believe you should be able to get some current between the tail and the tongue with a copper coin. Enough for a fairly dim LED nose, maybe?

@futurebird I got half a volt with a US quarter, and half that with a penny. Lemon or lime don't seem to be a factor (based on more pigs).

@shtrom That's more that I thought one would get without using something with zinc! A zinc tail should really light things up. (or a galvanized nail)To light an LED one needs about 1.5V but some will glow faintly at .9V

@futurebird @shtrom more modern LEDs will light a little brighter, not that much more

@shtrom Oliver has done the research and the time has come to bring the famous "Lemon Pig" of the new year into the age of electricity. I feel like it can't be a coincidence that these things are batteries. If you stick metals into container filled with an acid you have a good chance of making a battery. And that is what all of you have done!But you have not harnessed the POWER of the lemon pig. We must chain these pigs tail to penny across the world and unleash their potential.

@futurebird @shtrom Red LEDs need around 1.8 V. There's a fairly simple formula that relates voltage with wavelength of light. 0.9 V would only be able to produce infrared light.

@mansr @shtrom That’s what the specs say but they still glow at that low of a voltage.

@futurebird @shtrom Maybe if the power supply has so much ripple that the peaks exceed the forward voltage drop. In order to produce light, an electron has to drop from a higher to a lower energy state, the difference turning into a photon of the corresponding wavelength. Without the equivalent voltage, nothing will get any electrons into the higher state in the first place.It's not at all like an incandescent bulb that gets gradually brighter as the voltage (and thus current) increases.

@futurebird @shtrom Would it be possible to make a voltage doubler, or more with a circuit like this? https://www.instructables.com/DC-DC-voltage-doubler-simplest-possible-circuit/It all depends on the current you can get out of the pig I suppose. That of course depends on the surface area of the metals, among others.

@shtrom @futurebird it looks like a Joule Thief circuit might be able boost that .5V to light up at least one LEDhttps://en.m.wikipedia.org/wiki/Joule_thief

@LockEx @futurebird ok, so. I went digging into my odds and ends, and I think I was able to build a functional Joule thief (mainly based on https://www.youtube.com/watch?v=K53beWYdIpc).It works on the bench, but unfortunately not with the lemon pigs...I don't think the pigs are ready for this sort of power demands.

@shtrom It'll take a fair bit of current to saturate that toroid., a smaller core might work better near the limit.@LockEx @futurebird

@zl2tod I suspected this might be the issue. I'm very fuzzy on toroids. I'll see if I can dig up another one. @LockEx @futurebird

@shtrom @zl2tod @LockEx @futurebird 0.5 V is just on the borderline for many transistors. Another pig in the series might just do it.

@marshray @shtrom @zl2tod @LockEx The spaceship rattles with the blows from enemy craft as I push the engine near the limits of physics. We might just escape! "More pigs! We need more pigs online NOW!"The sharp scent of copper and lemon juice waters my eyes.

@shtrom @LockEx @futurebird A pig power is less than a horse power, it would seem.
