I would like to make a 3w solar led garden light to illuminate small tree. I was going to use an 18V 5W solar panel (Peak Voltage: 17.2V Peak current: 0.29A Open circuit voltage: 21.6V Short circuit current: 0.33A) to charge a 12v battery (Capacity : 4800mAh Rechargeable Li-on battery Input voltage : 12.6V Output voltage : 10.8~12.6 DC Output current : 1 - 2.4A) . I have found a charge controller which I think will do what I want (3A 6v/12v PWM solar panel light controller battery charge regulator http://www.banggood.com/3A-6V-12V-P...ry-Charge-Regulator-Intelligent-p-997571.html) The led I was going to use is 3W Voltage: 3.4-3.6V current: 600MA. I know I will need a voltage regulator to get me to the led forward voltage, but other than that does this look possible? Would an led driver be required? If there are any parts which someone would advise changing I am very happy to take advice, any help very gratefully appreciated.

I was looking at an instructable (https://www.instructables.com/id/Solar-Powered-Light-Graffiti-Projector/) involving a garden light hooked up to a red led instead of a white one. It shoots a picture out at night onto a wall or something like that.I'm wondering if the garden lights are too dim or don't charge fully. We used to have some lights of those type, but they would make a dim light for about 5 hours, then emit a very very weak light. I'm thinking about just buying a trickle charger from here, then getting a bright green or blue led, batteries, and waterproofing it. The problem is, I have nil knowledge about solar chargers/what voltage to use.Can anyone help?

I'm trying to make use of my solar powered garden lanters, you know, those ones you stick in the ground. The solar panels as far as I know still work, and have the batteries to go with. I'm pretty sure its just the buld that needs replacing. But honestly I dont use them anymore and I'm trying to find a better use for them but have come up with blanks.

Question by Kingmishra | last reply
I'm trying to change the battery in a solar walkway light to a 6V. The reason for this is Im also now using a light that contains 21 LED's at 4.5V instead of the 1 LED that is in the light. The charge for the battery is from an external solar panel at 10V. I don't think the charge controller in the light can handle the volts in the battery as the light is always on - even when the panel is not connected. Like the power from the battery is going backwards thru the controller. I do see a diode in the controller and was wondering if I just need to increase the size of it? Please help. Thanx...

I have a decorative garden light I am very fond of, but the solar charger/led light is no longer working. We tried switching out the batteries with new solar rechargeables but that didn't help. I'm game for replacing the whole thing, charger, light, sensor and all, but haven't been able to find replacement kits anywhere. The current unit uses one small solar panel about 3 x 4 inches and two AA batteries with one LED. Clearly I'm not searching for the right words. TIA

I am building retaining wall and am considering adding built-in lighting by using empty wine bottles that have an LED light inside, and a cork or silicone to seal the bottle shut. Optimally this set up would be solar but I could arrange for power if needed. I'm thinking of lights about 2 or 3 feet apart, lying horizontally embedded in concrete except for the bottom. The neck of the bottle would be buried in the retaining wall. It would look like a large glass blob in the concrete. Can someone help me figure out the best way to make this? Thanks in advance!

I was thinking: If you used a post hole digger and made 2' or 3' holes throughout the garden, then dropped an old pant leg or other scrap fabric down the hole, filled it up with soil while leaving some fabric exposed above the soil, covered the fabric with an inverted clear plastic or glass bowl, would this draw enough moisture through the fabric to irrigate the plants near the bowl? I'm thinking the sun would heat things up for condensation on the glass which would drip down the sides to the soil while capillary action would draw deep soil moisture through the fabric to the surface where garden plant root zones are. Anybody try this before?

Question by NathanielB10
We're now offering solar panel kits - 45 watt, 65 watt, and 85 watt - when combined with a battery pack makes a great solar generator for emergencies or for fun. Solar Pax generators are the 'bigger brother' of the Qwik-Solar. Solar Pax has very minimum assembly - and everything is already wired with quick connects. Use to charge any battery pack with a 12 volt outlet. We make these kits in Ohio. We set up a 'Mini-Catalog' on our website to make ordering easy. And we put together a page on our other site "Lamp Light from Sunlight" you might enjoy - it shows a 'Solar Pax' from 1954. Update: We've changed some domain around to better reflect our solar generator line up - the 'lamp light from sunlight' link above is active again.

HeyCan any of you think of a way you can replace (electrical)machines in a garden with its mechanical equivalence, while at the same time making its replacement low maintainance?It can also be decorations. Basically create mechanical stuff that looks good in a garden.Some devices that may be workable:+ A water timer that uses a mechanical clock that powers a mechanical valve, and its mainspring is recharged every time the water rushes though it.+ A passive water pump that is made of a black plastic water bottle and two valves. When hot, the air inside pushes water out. When cool, new water is pulled in by the cooling air. It can be used to pump water slowly to a 'not' so high location.+ A sterling engine can be used as a more active solar pump to pump water to a higher location, however its use of moving parts means it more likely to break down than the 'passive pump'. If it requires a kick start to run, then place a mini turbine to provide the starting force.+ Use the above pump to create a fountain+ Perhaps as a replacement of solar powered markers, get some crystal that emits light when shaken("which quartz i forgot..."), and get it to shake around automatically.+ Mechanical garden music box would be a nice addition(wind powered music box). Double points if its either reprogrammable, or plays a different instrument such as drums.

I would have loved to actually do this but I have had the idea for ages and done nothing, mabye you can? I have plenty of solar powered garden lights that don't last the night. I also have plenty of rainy + windy weather. Bunnings sell the solar powered garden lights from $2 each, Wouldn't it be wonderfull if someone came up wtih a mod to add a little water proof wind generator to help charge these lights equally as cheap? In my area when we don't have sun during the day, we have wind, so the math is easy. Thought someone might appreciate the idea, there are retailers doing this (far and few between) 4 lights for over $100, you can do better!

I read an article on Dave's Garden a year ago on plants with Star Trek names, and I just adore the idea of having a science fiction themed garden. Looking through some more plants, I've come across even more plants that would fit within a sci-fi/outer space theme. Coleus: Darth Vader Saturn Saturn's Rings Solar Flare Solar Shadow Solar Sunrise Vulcan Daylily: Alien Alien Contact Alien Encounter Alien Escape Pod Alien Invader Alien Landing Alien Skin Alien's Eye Android Android Dreams Andromeda Asteroid Astral Voyager Beam Me Up Beam Me Up, Scotty Ben Kirk Big Dipper Black Hole Borg Technology Cloaking Device First Officer's Log Galaxy Quest Klatuu Barata Nictu Life on Bajor Notify Ground Crew Photon Torpedo Romulan Deflector Spock's Ears Vulcan Logic Hosta: Captain Kirk Enterprise Foxfire X Philes (just for fun) Galaxy Galaxy Light Gamma Ray Kiwi Milky Way Little Dipper Lunar Eclipse Lunar Orbit Lunar Sea Outer Space Saturn Starship Striker Super Nova Venus Voyager Vulcan These lists are not complete. I looked through 5,320 daylily names out of 38,449 on Dave's Garden and then filled in with some names from the article, and I'm sure there are more genuses with sci-fi plants. The reason why there are so many hostas, daylilies, and coleuses is because they're relatively easy to hybridize and propagate. I started looking through African violets, but half-way through I was pretty sure I wouldn't find any. I wouldn't be surprised if there were some more in the Liliaceae family such as with tulips, but phew, that's a lot of plants. Looking through some of the names, it would be relatively easy to do a Lord of the Rings or fantasy-themed garden. I even found hostas called "Dot Com" and "Website". Hybridizers certainly get creative when it comes to names. I think I'll send my brother-in-law a hosta called "Twisted Sister". The image is of a basket plant I have. No neat name, but it looks kinda sci-fi in the picture.

I have a pergola at my main entrance and I want to hook up solar lighting to light up the path. I was thinking to get 6 solar garden lights and take them apart and place the solar cell on the top of each pillar, run the wires down the outside of the post and drill the post laterally and bring the wires in from behind to the actual pathway. From there hook up the LED light that was originally IN the garden light. My question is...Is there any way I can get just ONE solar panel and operate all six LEDs off of that one panel? I am assuming I can go with one panel, solder a photocell (12v) inline and lead it to a battery holder of eight AA batteries. From there it goes to an Automotive grade 12v dome light, similar to a Festoon Bulb. These come in various colors. My only question is....What wattage should I get the solar panel? Could I get the solar panel with a built in photocell similar to what garden lights operate with?

Looking for advice on low-tech ways of solving a prob, hope someone can help. I really want to create a very small waterfall in my mini-garden, maybe 6” at the most. I can’t use solar power, as my tiny garden only gets about an hour or so of direct sun around noon (I found out that less then direct sun doesn‘t work; I have a floor-standing 4-bowl cascade that stops the instant a shred of cloud gets in the way). I can’t have mains electricity outside, partly because most of the area is paved and I can’t get the cables safely out of the way; I could get cable around the wall, but it’d have to go round three walls to get it where I need it, and I’m not sure about having the cable overhead. I’ve been searching for some time for some kind of power-pack that I could charge up on the mains, then plug into the feature; I don’t think household batteries would run for very long, I was thinking of something with a bit more punch. Either they don’t make anything like this, or I’ve not yet been able to find the right keywords to track it down; I get untold pages of “solar power” options. So, basically, people, I’m asking: is there such a thing, or anything that would solve my prob? I’d have to buy a tiny pump and all the rest of the stuff, but if I can’t power it, what’s the point? Some background: I’m visually impaired, so intricate work is out of the question; I’m not so much low-tech as no-tech; my only power tool is a small cordless drill/screwdriver; I’m not confident about messing with electricity I live in rented accommodation so I can’t do too much to the structure (ie get the paving lifted and cables put under them, or even running round the walls)
