How to Make a Solar Powered Walkway by depotdevoid

Step 5: Final Thoughts

I guess the one downside (if you see it as a downside) to having a glowing path in front of your house and visible from the street is that it seems to draw in weirdos like moths to a flame.  I have on two separate occasions gone out of my garage for a smoke and caught someone on the path--one guy was just standing there staring, and one lady (who was in her forties and clearly on LSD or maybe extasy) was hopping from brick to brick.  On the other hand, everyone oohs and aahs over it when they come to visit and I like walking on it, so on the whole it's a good thing.

This was one of the first electronics projects I did after we bought our new house last spring.  I'd been moving and unpacking and fixing up little things for a month and a half and was just sick of neglecting my more eccentric hobbies, so this was a nice entry back into doing strange things with multicolored lights. I haven't posted it until now because I had other projects going, and then somewhere during the month of October while I was busy making my proton pack extra awesome, a big wind storm came through and knocked the solar light out from under the newspaper box, banging it up a bit.  It's still attached, but the lights don't work all the time.  I finally rigged up some battery power for the lights so I could take some decent pictures of the path.  My plan is to either repair it or replace it with one of the other ones I picked up.  I hope I can repair it, as I'd like to add more lights around the yard once I've done more with the landscaping.

As always, thank you for looking!  Please take the time to leave a rating and a comment, they are always appreciated.  I would also love to see pictures if you decide to make something like this yourself.  If you post your pictures in the comments section, I'll send you a DIY patch!

Hey, I'm 37 and I would probably hop the bricks too... and I wouldn't be on anything... just let people have their fun and enjoy life!! you've created something cool and not often seen so live it up and let others do the same, long as they don't break anything or hurt anyone :)

Keep building and being awesome!!!

Thanks Tabbytha! It's not so much a comment on the act of hopping the bricks (which I do myself), so much as on the specific people I've discovered in my front yard--they usually have googly eyes and give me a distinctly creepy vibe!

On the other hand, I had one lady who was out walking her dogs compliment all the lights in my yard, and later on that summer asked me to come visit a science museum summer camp and teach kids about being a maker. So like I say, some good, some bad, but mostly good!

Great project. I couldn't find if this was covered, but how long do the lights stay lit with that setup?
depotdevoid (author) says: Aug 18, 2011. 7:48 AM
Thanks surf frog! Depending on the time of year, they're good for 3-6 hours. I suspect dropping in some better rechargeables would extend that significantly.

Right now I am living in an apartment complex, and am trying to find any excuse to make these! They are so whimsical looking, and the possibilities are almost limitless. Thank you for such a great instructable. I can't wait to make these. C:

Thanks Shilicious, I'd love to see the results if you do!

Very Cool!! Great Job!

I've done something similar disassembling a solar landscape set & conch shells.

But I'm going to us this one for sure at the canal lot. Love it!

Cheers

Thanks Caribsailor! Post some pics when yours is done. Also, you should consider subscribing to me, I've got version 3 of this concept in the works, hopefully to be completed in the next 2-3 months.

Cool. perhaps a motion detector would help with the odd folks that seem drawn to these (you know, moths and flames). Or perhaps a foot switch that has to be trod upon to activate the lights. In any case my wife will be getting a lighted path for her birthday!
depotdevoid (author) says: Aug 29, 2010. 4:41 PM
Awesome, post some pictures when it's done!

Great idea and project - I'm in South Africa and will be doing a similar project - I want to do it on steps as we often have power outages.
depotdevoid (author) says: Jan 22, 2010. 5:54 PM
Hey, that's great!  We don't really have that issue in the U.S., and I never really thought of using something like this for a power outage problem.  I'm totally amazed that someone half the world away from me has found a use for my humble little project. 

Thanks for commenting, and if you do make something like this, please post a picture or two so I can see it!
CyborgGold says: Aug 17, 2010. 6:43 AM
Not only does it solve power outage problems... this idea got me thinking on alternate uses of my own for solar lighting. I live in an upstairs apartment with stairs on the outside of the building... my wife tripped last week and sprained her ankle because the stairs are too dark. I am going to call my landlord up and suggest something similar for the stairs here!

I loooove this project and I really want to make it for my backyard.  However, I have never done any electrical projects or soldering.  I am a quick study, though and I think I was able to follow most of what you described.  But is there anyway you could explain more to a beginner the parts about separating and connecting the electrical parts or maybe more detailed pics?
I know it may not be possible since you've already completed the project, but to anyone else who is making the project, pics would be appreciated.  Thanx.
depotdevoid (author) says: Jan 25, 2010. 10:25 AM
Thanks a lot Eeloie, I'm glad you liked the project!

The bad news is I have no pictures of the detailed electronic work.  The good news is, this is a super simple soldering project.

For equipment, don't use one of those big gun looking soldering irons--go to Radioshack and buy the cheap-o 25 watt pen style iron and the thinnest solder you can find.  Practice soldering and desoldering on some broken electronics, or something you can pick up for cheap at the goodwill or salvation army before you start this project.

When you remove the LEDs, I find it's best to put gentle pressure on one side of the LED and melt the solder on one of the leads.  The LED will push up a little bit.  Repeat this on the other side, going back and forth until the LED comes off the circuit board.

It's also important to realize that LEDs have a positive and a negative side--almost without fail the negative side of the LED itself will have a flat spot.  When adding the speaker wire to extend the LED, make sure that you keep track of which side is positive and which is negative--I always use the silvery side of the speaker wire for negative and the coppery side for positive.

When soldering the wire to the board, you simple put stripped ends of wire through the circuit board and solder it to the copper pad on the circuit board.  This is usually very simple, as the solder will adhere both to the pad and the wire nicely.

The only other soldering work you'll have to do is extending wires, splicing wires, and soldering LEDs on the ends of the wires.  I like to simply twist the bare ends of wire or LED lead together, dab on a little solder, and since this is an outdoor job try to protect the bare wire with both epoxy and electrical tape (to keep the water out).

I suspect this will be a good beginner soldering project.  It's pretty straightforward and easy to do.  The first soldering project I ever attempted was the Magnetic Fridge Lights instructable, and let me tell you, that was HARD!

Good luck on this, Eeloie!  If you have any more questions or if I haven't answered everything here, just ask.  If you do end up building something like this, please post some pictures!

I love this...but wonder how it would work in NH with snow on the ground all winter...will have to play with the idea -- thanks for posting!
depotdevoid (author) says: Jan 15, 2010. 8:11 AM
Hmmm, I don't know.  My dad lives in a snowy area, and the sun jar I gave him works just fine all winter long, so it may not be an issue.

I'm glad you liked it, thanks for the comment!
greenseeker says: Jan 16, 2010. 2:37 PM
The main winter problem I foresee is how slick the glass will be with a thin layer of snow on it.

You'd also probably have to be cautious not to split a block open with a shovel or scraper.
willrandship says: Jan 24, 2010. 6:45 PM
How about mounting them on a tree or to the sides?? that way they still illuminate a path, but don't get stepped on or slipped on.
depotdevoid (author) says: Jan 24, 2010. 8:51 PM
I actually pulled them all up this weekend, I'm moving them to the sides of the path.  I think it will be safer that way in the long run, but still look good.
depotdevoid (author) says: Jan 16, 2010. 6:21 PM
Yeah, they do get a little slippery in the rain (a constant from september until may here), but I haven't had any major accidents yet.
briankangaroo says: Jan 21, 2010. 9:43 AM
 To prevent slipping, I often find an excuse to sandblast some type of design into the face of larger format glass pieces that are installed in bathroom floors and lit with LEDs. . 
depotdevoid (author) says: Jan 21, 2010. 12:54 PM
Oh wow, that is a totally awesome idea!  I'm not even sure how I'd go about doing that , but I can imagine it would look great!
jayfike says: Jan 21, 2010. 6:29 PM
An easier (cheaper) way to produce a non-skid surface would be to use a chemical etching solution.  You can probably find it in a craft store.  I think that this will diffuse the light better and hide the LED.

I think this is a great idea.  Love the green and blue.  I will be making this soon!
depotdevoid (author) says: Jan 21, 2010. 7:14 PM
Thanks jayfike, the chemical etching solution sounds like a good idea . . . I was looking through the instructions for the dremel I won in the Halloween contest, and they say that some of the attachments could be used for glass etching.  I may play around with that one of these days.

If you do make some of these, please post a picture, I'd love to see the results.
briankangaroo says: Apr 28, 2010. 10:43 PM
 jayfike is right... chem etching is the cheapest way to etch and diffuse the light. Mechanical etching with your dremel can produce some cool results. The cheapest way to sandblast (my personal favorite) would be to use a hand held Harbor Freight Sandblaster (around $15). Use contact paper and a hobby knife to cut your designs.

Hi:
Your project is great!. I like the way you write. It is funny about  the lady that "was hopping from brick to brick" :)

Thanks a lot guitarra!  I like writing these things up, and I try to inject a little humor hear and there!
kstlfido says: Jan 21, 2010. 1:58 PM
Cool project! I've been planning something similar for our camp perimeter at burning man. We had 12 garden lights and they all got trashed.

I would use plastic blocks instead (safety) and would try to run the leds in parallel, requiring just 2 wires for a whole chain. Connect all the panels in parallel and use a single gel cell for batteries.

Or something like that! Anyway, thanks for the inspiration!
depotdevoid (author) says: Jan 21, 2010. 2:49 PM
Cool, It's always great to know I've been an inspiration!  If you do this for burning man, I'd love to see some pictures!
anneathema says: Jan 21, 2010. 8:15 AM
I love this, and I'm so doing it this spring!!!
depotdevoid (author) says: Jan 21, 2010. 11:57 AM
Thanks a lot anneathema, please post some pics when you do!
jsdrury says: Jan 19, 2010. 7:00 PM
Those are sweet!!! I work and tinker with LED's a lot, I just got a shipment in of Ultraviolet ones and I am definitely going to put a few of them to the test with this project!!! I'll test out the winter weather deal to since I live in Buffalo!!!  I'll let you know sometime next week after my son and I make a few... I will however try the "hole drilling idea" I think I have the right bit... I think I'll also use some shrink tube to help weatherize the project...(Harbor Freight can be a great place for those who love to Tinker for Less... anyway REALLY COOL PROJECT!!! Thank you...
depotdevoid (author) says: Jan 19, 2010. 9:01 PM
Thanks a lot jsdrury, I'm glad you liked it!  Once you and your son have made some, please post some pictures, I love to see what other people do with my instructables!
Lehmeier says: Jan 16, 2010. 3:14 PM
I like the blocks a lot! i might try this for the back yard along the fence.  Great Idea!!!
depotdevoid (author) says: Jan 16, 2010. 6:22 PM
Thanks Lehmeier!  If you do, please post some pictures!
KEUrban says: Jan 15, 2010. 4:55 AM
Nice 'ible.

You might consider drilling a small hole in the glass block, inserting the LED and connection, throwing in a grommet, and then sealing with silicone caulk. That way, the connections would be weather-tight and well-protected. Drilling glass is easy with the correct bit. See my 'ible for drilling suggestions.
depotdevoid (author) says: Jan 15, 2010. 8:15 AM
Thanks KEUrban,

I did originally plan on drilling a hole in the block, but I didn't realize at the time that you could get special bits for drilling glass--I tried it with regular drill bits and failed, of course!

By the way, those bottle lights look great!
xgl0baltk says: Jan 15, 2010. 5:50 AM
 In the case of those weirdos running around ur front path i wouldve put a pushbutton under the first block and the last block instead of a switch so when u step outside ur door it illuminates and when u step on the first brick too..
sure it looks super the way it is..no doubt.. but just thought about that.. 
and as KEUrban said weather seal it cuz when rain comes ur leads are still abit exposed even under the the gravel and dirt
=)
but congrats!.. wish i had a house to do smthin like that :D
depotdevoid (author) says: Jan 15, 2010. 8:10 AM
Thanks, I'm glad you liked it!  Owning a house is great, but damn expensive!  Having the freedom to do what I like with it and paying off my own mortgage instead of someone else is totally worth it though.
