Here are two design variations on a traditional voltaic cell. Both designs are solder less and easy to construct from common household items. The flower and lamp are basically giant paper batteries with the wetted paper acting as a salt bridge between the wires.

I used the cardboard from a box of soda as the base of the lamp and construction paper for the shade. After making 6 pairs of fairly evenly spaced holes in the base I rolled the paper and marked where the holes lined up- in this example they were an inch apart. It's important that the wetted paper containing the wires doesn't touch it's neighbor or the current won't know where to flow. Cut v-shaped pieces out near the bottom where the shade connects to the base to prevent that from happening.

When people recreate, remix an instructable, or any other work, based on the work of other people, you should credit the originale Author.
And neither here or in any other website where you mentioned your work, you say that it is inspired my my instructable published more than one year ago.

A credit would have been appreciated.

1. She doesnt picture a lemon, nor use lemon juice in this Instructable.
2. She uses voltage generated by using two dissimilar metals for a battery, not a lemon nor its juice, as you use as your final power source.
3. You are not the first person on Instructables, nor on the planet to use a lemon as a component in a voltage device because your instructable was posted a year ago, nor is she the first to use saltwater.
4. You could have used the "Private Message" feature to contact her regarding your concerns; but it appears you want to publicly accuse her.
5. Public accusations like your claim do nothing but let the readers think she may be guilty of what you accuse her of. I dont think she is, and to me you are being mean.
6. Being mean breaks the "be nice" policy.
I doubt she was the one posting this on hackaday. The submitter probably hasnt seen yours at all.
While you might have a claim about the plant/flower-like design, that design exists in nature...so giving you the benefit of the doubt, if she'd seen your instructable, she should mention it. If she hasnt, then I dont think she must.
Regardless, links between all similar projects would be nice for people wanting to build a device like this. If I were her, or you, I'd link to the other.
I compare this to a basketball player patenting the "lay-up", then claiming other players need to credit him if they had used part of his technique by jumping.
"Imitation is the most sincere form of flattery", or something along those lines. You should feel good about similar information you share to be presented to a larger audience; isnt that one of the benefits of Instructables?
With that said, madaeon, your project mentions many details of your trial and error, and is quite excellent.
This one is clearly inspired by mine, and at first I loved it! Someone is actually teaching using this! It's nice that i published it.. hey wait, she doesn't mention mine, or at least where she got it.. Then, hey, on this site they talk about her and how clever she was...
Am I wrong when I think that one line, to say "I took idea from this, stop." would have been appreciated? Should I write to ask this? I don't like when the system works like, I present this as my idea, hope no one notice, if so, well I will say sorry and post a line.
Sharing your ideas here for free, you think at least you will get a line when someone uses your idea.
But maybe after all I am too strict, she's just a teacher and I am pleased to know that these children have had a fun lesson ;)
So this will be also my last post on this topic.
Looking forward to more instructables from you Mad-Aeon. :)

Looking at the different members approach on voltaic cells helped me understand it more thoroughly and attempt my own. That's why having sites like instructables is so important for innovation and discovery, so we don't have to recreate the wheel each time we try to do something and we can learn from each other's work without wasting time or materials.
The craft felt may be too thick for this to work.
