What I want to share with you today is a project I'v been working on ,
I'll call it the eco orb and eco battery , ok so I didn't put to much thought into the name but that's not important ,
what is a eco orb you ask ,
basically its a fancy led lite that runs on clean energy ,
here's an Idea of why I can up with this idea ,
I wanted a light that runs on clean and free energy ,
I wanted to make an easy to use battery that runs on water ,
that's reusable without the hassle and mess that come's with it ,
I wanted to make something that could run an led or two without any help from a joule thief ,
so I needed to make a battery that was completely independent ,
next I needed to make a light for it that looked nicer then a led on a couple of alligator clips ,
so I'm pleased to show you my easy solution to make your own eco orb and battery .
Step 1: Supply's
a hardware case with eight compartments , found mine at the dollar store I need the nails anyways ,
eight piece's of three inch solid copper , hardware store got a foot of ac wire then stripped it ,
one green led , got these on ebay 100 for $ 3 dollars ,
some wire ,
eight nails zinc coated , I used the one that came with the case ,
white ping pong ball . this was free but you can get them at the dollar store ,
total cost to build this is about five dollars to build but I have lots of leftovers from this project ,
tools I used were ,
glue gun ,
screwdriver and screw ,
hammer for tapping ,
note i'm not responsible if you get hurt always be careful around shape objects and don't run with scissors .
ok let's get started .
Step 2: Prepare the Case
then we need to drill 16 small holes for are leads to make the cells ,
I used a screw and a screwdriver ,
now make two holes on the lid above each compartment . as shown in the picture ,
leaving about an inch away from each lead for each cell ,
once you drilled all your holes as shown we can move on to the next step .
Step 3: Inserting the Leads
so lets start buy adding the nails , we need to form a pattern to make it easier to wire up , as shown in the picture .
so put one nail in the first cell at the top and then to the next cell at the bottom , repeat this on both sides ,
then put the copper in all the remaining holes ,
when your done you should have two leads in each compartment one being copper and the other the nail ,
then put a bit of glue were you've inserted the leads ,
now you've made your cells it time to connect them ,
OK on to the next step .
Step 4: Connecting the Cells
ok so now we must connect the cells ,to do this each cell needs to be in this pattern copper to zinc copper to zinc , as shown . will do this by bending one inch of the copper lead around the zinc lead to the cell in front of the other ,
but first we must bridge the two side's together , as shown ,
will do this by bending the one inch of the copper lead around the zinc lead to the cell on the opposite side ,
once you've connected each cell we must make sure the connection are connected ,
now here's were the tinfoil come's in ,
just to make sure the leads are connected I took small pieces of tinfoil and covered each connection ,
once that's done it should look like the picture above ,
ok so you completed your eco battery now we can move on to the next step ,
Step 5: Making the Orb
take two four inch wires and strip both ends ,
then wire both leads on the led and glue the leads so the leads can't touch ,
next make a small hole on the ball big enough for your led to go in ,
once you inserted your led glue it into place ,
ok your done now to test what you've made .
Step 6: Testing
next take your orb and wire it up to the battery , remember copper positive and the zinc is negative ,
turn out the lights and see it glow , so now your done ,
be for I say finished here's somethings you may want to know ,
I hooked up my voltmeter to see how much power where getting from the battery ,
results not bad i'm getting 3.2 volts more then enough for a couple led's ,
how strong is the current you ask I got up to 200 ma , and the led that i'm using only needs 50 ma .
as shown in the last picture I had it running the orb and two other led's .
how long doe's it run ,
I filled it up and timed it , lasted for two hours before it started to fade out ,
Step 7: Finale Thought's
like I said I tried a few different Ideas did not perform as well as this one did ,
before this battery I always was stuck needing a joule thief to get enough power to light an led ,
now if you wanted greater power output you could use a joule thief to get the maximum results ,
