Step 16: Update!

After several people pointed out that there really should be some sort of charge protection circuit, d3z0rian commented suggesting this!


It's a small circuit that automatically cuts off the power when the battery is fully charged. At only $1.59, it's a bargain! In less than a week from February 13, 2009 it should arrive. I'll post another update with pictures showing the new setup!

February 22, 2009: The part arrived yesterday, and I just finished modifying the DS with the chip. It changed so much that I'll have to post a new instructable. I'll put a link to it right here when I'm done with it.

April 12, 2009: The newer version has been published! Go to http://www.instructables.com/id/Solar-DS-quotLightquot-Redone-and-Greatly-Impr/!
Hm. How fast will this charge?
Fairly slowly. It puts out a fraction of the power that the charger could provide.

Can this be adapted to work on a DSi using the charging port? I'm wondering if you can cut a charging cable to plug into it, instead of running wires directly to the battery?<br><br>Thanks.
Yes. Go to the updated Instructable (http://www.instructables.com/id/Solar-DS-quotLightquot-Redone-and-Greatly-Impr/) and look at step 17. Have fun!
&nbsp;Did you hear about the larger DS XL coming out? Maybe this means we can tack on more panels?<br /> <br /> <br />
Is there anyway i could make this for my DSi or PSP???

This is really nice, except that I can't play the Nintendo DS Lite outdoors as I'm having trouble seeing the screen especially when it is too bright.
I don't play it outdoors. I don't even charge it outdoors. I play it indoors and when i'm done I set it by a window to charge.
Oh!, anyway I think in doing so will shorten the life of your LCD screen as heat will degrade the screen (not to mention other parts such as the casing) as I have proven it to myself with my other LCD devices such as: Wristwatches, Calculators, 2-Way radios, Original Game Boy, GB pocket, Caller ID, etc. that was placed/stored in a warm to hot room or directly being exposed to sunlight and the degree of degradation depends on the quality of the LCD. e.g My Casio watches LCD degrades a little vs my Timex watches and other noname calculator vs branded ones. Hope that the LCD of the Nintendo DS Lite is far superior than its predecessor. (So, now I learned my lesson I'm keeping all my LCD'd devices in a cool place). By the way I from a tropical country.
Oh, ok! Unfortunately, I don't know how to fix that problem...
I used heat sheilding similar to what they use on the space shuttles and i can leave the DS out all day without any damage.
Cool! Any pictures?
Sorry but no, i dropped the D@#$ thing and it broke itself and my toe.
Will rebuild eventuall and post pics. also my toe is better now
well, for one, the screen is facing down while chargeing solar.
Hi i need to know how to make a DS charger, out of my DS Lite Car Charger it would be for a Lite, cause i got the new Deltora Quest DS Game and its japanese. I need a charger because all my chargers always got stoled or i really dont know if i just trew it out somehwere and cant find it. I want to make it so the volt is circa maching cause to not torching the ds or the cable. ANd i need to cover the wries so i not get torched or gets an electrical shock. (Can i buy a DS Lite Charger in Fona??? If you know what that is, or in Expert if you know what that is, or where else could i buy a brand new one Nintendo DS Lite Charger Dark Sponge????????? (PS: I lives in the country Denmark)
get a normal input and cu it in halft strip the red and black wire then cut the car charger in half and strip the wires then put the red with red and black with black solder or e-tape u need to make sure its the same voltage
I just saw a ton on ebay<br/><br/><a rel="nofollow" href="http://shop.ebay.com/?_from=R40&amp;_trksid=p3907.m38.l1313&amp;_nkw=ds+lite+charger&amp;_sacat=See-All-Categories">http://shop.ebay.com/?_from=R40&amp;_trksid=p3907.m38.l1313&amp;_nkw=ds+lite+charger&amp;_sacat=See-All-Categories</a><br/>
so cool i have experimented with solar panels and made a generator that goes on to your arm so while you move your arm you charge your ds but the problem i had was the ds had charged up in flicks so it would flick on flick off and i ended up damaging my battery lol not very effiicent when the light on the ds go on when charging wasting electric
How comfortable is it to hold? How strong are the solar panels? Do I need to worry about breaking them if I drop it? Thanks and awesome idea!
is it possible to connect the solar panels to the charging slot at the back of the ds so it uses the ds' own cutoff chip and you can see wether the ds is charging with its indicator light?
oh soz i should of read through the comments before i posted, anyways... this is a great idea, could save alot of money in the longterm
Actually, this isn't going to save you any money unless you pay waaaaaay too much for electricity. The solar panels are mainly for the convenience of not having to carry a charger with you.
Hey, i like this! i just got an msi WIND about a month ago, so now im thinking about how to mount solar panels on top. i've been looking around the WIND forums and i have yet to see anyone with a solar trickle charger mounted to theirs.
That would be awesome! I would be a litte careful around the battery, though. Those laptop batteries can be pretty violent. You would probably need a cutoff chip and a charging circuit (unless it is built into the battery). <object width="425" height="350"><param name="movie" value="http://video.google.com/googleplayer.swf?docId=http://video.google.com/videosearch?q=laptop+battery&hl=en&emb=0&aq=-1&oq=laptop+batter#"></param><param name="wmode" value="transparent"></param><embed src="http://video.google.com/googleplayer.swf?docId=http://video.google.com/videosearch?q=laptop+battery&hl=en&emb=0&aq=-1&oq=laptop+batter#" type="application/x-shockwave-flash" width="425" height="350"></embed></object><br/>
how long does it take to completely charge? does it hold its charge? anyone you know ruin their DS?
I don't know how long it takes to completely charge because I have no indicator for when it is done. It can hold its charge just as long as the unmodified ds can. It would be pretty hard to ruin your ds doing this unless your solar cells put out too high a voltage. This project doesn't open up the ds and put the stuff inside at risk, so it is safe.
How durable are the solar panels? I have three kids with DS's and would like to try this. Would the suffer the abuse of a 4, 6, and 8 year old? I am thinking I might be better off simply going with a separate charging pack like the one you have drawn. Will a 9v battery completely charge the DS?
there are solar panels available that are not made of glass and that are almost indestructible. they're flexible, and i think you may even be able to cut them out with scissors to fit. the only downside is that they are a bit more expensive, but they will look pretty slick, since they're paper thin.
Where can you get said solar panels?
Sorry, but the solar panels I used are made of glass. They are very sturdy, but I can tell one or two drops on a hard floor would shatter the panels. For your second question, a full 9v battery would not fully charge a DS, but 6 AAs should.
oooooh. interesting...
sweet. i plan on doing this soon.
is this safe? =( i dont want to ruin my ds =( and how do i solder the wires? <sup></sup><br/>
This is perfectly safe for the ds unless you connect everything totally wrong. You should keep checking back to see when the update comes out, and do it that way. The update has a chip that sill stop the charging when the battery is fully charged. For soldering, you could probably find several instructables on the topic.
ok =) thanks ill check for a soldering instructable and for the update =) but i still dont understand how you solder the pannels in step 2 =( sorry for the dumb questions im new in this =[<br/>
It's ok. In step 2 I just put two of the solar panels side by side, with the positive side touching the negative side. I bent the wires from the two touching sides so that they were on top of eachother. I then touched the tip of the soldering iron to these two wires and applied some solder.
oh =P i see, but one last question T_T (i think u hate me by now for all the questions ) if i apply too much solder to the battery terminal i could ruin it? =( <br/>
The only way that could happen is if you apply at TON of solder! (It's ok I like questions!)
ok =) ill try, where did you learn all the things you know of tech ???? =( its just i dont have anny real training and i would like to know where could i know more about tech =P, and thanks for being so nice with all the questions =]<br/>
never mind =P i already found a teacher =P finally im learn about this =D <br/>
Teacher? I learned everything I know from kits, the internet, and Instructables.
