Electroluminescent panels

Greetings, Anyone have any idea how electroluminescent (EL) panels are made? I see in this video https://www.instructables.com/id/Make-your-own-EL-wire-at-home/ that EL wire has a wire wrapped around another one, but what about EL panels.  They don't have wire wrapped around a sheet of copper, do they? Thanks

Solar Panels in Parallel? Answered

I know that you can wire solar panels together to combine the amps. But I've only ever seen this done with 2 identical panels. Would there be any problem with wiring up 2 panels with different A values?

Solar panel question

Hello i am long time lurker of instructables.com and i love the site and its inspired me to build a few things. that said onto my question.  i was at my local Dollar Tree Store (Dollar Store) and noticed the solar powered walkway lights. so i bought a few and decided i could salvage the solar panels.. so a few screws and some applied pressure later i have some small cells 35.6mm by 29.6mm with a model number (SC3630S-4N) and everything so i googled it and i get this website as the only one listing voltages and mA's but there are two sets and i am unsure which set i need to be aware of and exactly what it all means. http://www.aliexpress.com/product-fm/432233432-solar-cell-Embeded-Modules-Outdoors-wholesalers.html so any one can explain to me what the 4 values mean i know (V) is voltage and (mA) is amperage but why list them twice.

Solar panel uses??

Hey guys I'm needing the expert opinions of everyone here in the tech section. See I just mounted this 0.5 watt solar panel outside on a L bracket today (not just a couple tiny ones I pulled out of solar lanterns (does anyone want to see what it looks like mounted outside? I didn't think to take pictures until I got inside). Anyways, I've mounted it, ran the wire along the ground and in through my window (drilled a small hole below the window). Connectivity checks out good and I get about 20-21v and the full sun hasn't even hit it yet. The only thing is here though, this solar panel is meant as a trickle charging panel for car batteries and whatnot, and as such I only seem to be getting about 10-15ma (seriously wtf). I just resoldered this charging board from a solar lantern I had laying around, however I have a couple questions. I'm not entirely sure if this little board will handle the current/voltage (however it should as it's fairly low current from the solar panel) I've rigged up the board mostly like it was inside the solar lantern except longer/stronger wires. I have a switch on the positive line of the batt+ to the board. I soldered some thicker wires to the SOL connections on the board. Now I've seen a few of these and some are rather simplistic control boards and some actually have a bit of circuitry to them. This one appears to have resistors to current limit the LED (would be good so I don't blow it), however after following the traces on the board the led get's it's positive from that black transistor thing with 5 legs on it (what is that a power regulator?) The idea behind all of this here is that I can maybe charge up my cell with it or usb devices for example, but to have that come from a battery pack of AA's (to work as a buffer sorta-speak like a capacitor bank). I am a little miffled as how to make this work right the way I want it to. I would assume that once I get the battery pack situated I can disconnect the LED and use that connection for a charging cable, but then it would only provide power when theres no sunlight out (when you turn it on it turns the led on if there is no current coming from the solar panel). How can I do this guys I'm sorry to ask such stupid questions as I know to some of you's it's probably fairly mediocre but I'm a bit dumb.

How can I charge 12V Li-ion or lead acid batteries using a solar panel? I also wish to interface the three, i.e. the Arduino, the solar panel and the battery, together so that the Arduino is basically driven by the battery but as the battery discharges, the solar panel would charge it. What circuitry do I need? Also tell the specifications of the solar panel.

Solar Panel Construction

Hello Everyone, this is my first forum post!I had a question and couldn't think of a better place to turn to than this.Basically, I am constructing, or planning to rather, an outdoor picnic table. I want to add some gadgetry to it and make it more multifunctional. Sorry to be vague, but a lot of it is still being worked out and since I'm going to post the project on here anyway, I'd like to wait to present the entire project as a whole.My question involves the use of solar panels as a table top surface. I have a basic understanding of how to create a solar panel powered system (http://www.rain.org/~philfear/how2solar.html or https://www.instructables.com/id/Solar-Power-System/). But my question is this: does covering the solar panel with a piece of acrylic hinder its power collecting abilities? I'm thinking of covering the entire table top surface of my table with solar panels. Aside from the obvious downfalls of people using the table and blocking sun, I thought there would be enough time when its not in use to collect power. But obviously I can't have people eating right on the panels and damaging them. Any guidance would be GREAT! I just want to know if I should even entertain this design idea or separate the panels from the table altogether. Thanks!

solar panels questions

In the quest to turn my garage 'green' I started with a purchase of a Sunforce 60 watt solar panel charging kit. I already own a 12v 15amp charge controller that I bought from Green Energies. The Green Energies controller is bigger than the kit supplied so I'm currently using this one. My questions; The Green Energies charge controller is supposed to have a blocking diode in it. When I put my volt meter on the leads going back to the panels (panels dis-connected, controller still hooked to battery) I'm getting approximately 10 volts. Should there be any reading at all? I went out this rainy morning to see if there was any power coming from my panels. To my surprise I read 8-10 volts (depending on cloud cover). This leads to my next question. It is worth adding a boost converter? I suspect the amperage would only be that of the incoming voltage, not what it is boosted up to.. Close? If my guess is correct, my 5amp (system at full power, rated at 24vdc), would only be about 1.6- 2 amps @ 8- 10 vdc. I also suspect the controller is stealing some amperage. 0.5 amps??? That should leave me with at least 1 amp coming in and giving me a 10 amp day. Not bad for a rainy day. Right, wrong or hopefully close? I'm not seeing my battery come up to full charge. I'm using a marine deep cell acid battery from my boat. Every 5 years I replace it to insure the boat will start as needed. Paddling that craft back to shore is not an option. One reason could be the fact of the battery being 5 years old and it will never get back to full. Second I believe would be the draw going back to the panels at night. Will the panels draw power?

Voltage regulator for solar panel

I have built a solar panel as a fun little project, now it has come upon a big problem. The solar cells that I am using seem to have a higher amperage output and a lower voltage output in high intensity sun while having a high voltage and low amperage output in medium and low intensity sun. This poses a problem as my batteries were able to recharge during late winter and early spring but now are not able to recharge when there is the most energy to be captured during the summer. The average voltage during high intensity is about 11 while the voltage during medium or low is around 12.5 and 13. I want to know if there is a way to create a transformer to step up the voltage or create a voltage regulator that can withstand 13 amps so the battery can recharge properly. A link or any suggestions would help.

schmitt trigger for solar panel

Hi, I'm building a solar panel project that may use the charge battery and so on. As solar output is not consistent, I have a capacitor array to store charge before deliver it to the end devices. However if the solar output power is lower than the end devices(example charging phone) power load, it will probably on and off since the solar output is not enough. I would like to use by capacitor array to reduce the on and off rate by design a Schmitt trigger or perhaps it a flip flop circuit. For example if my Solar panel max voltage is 12v and my  device using 5v thru a voltage regulator that need min of 6v. So I would like to design a circuit to do this 1) When capacitor array discharge to 6v, terminate the circuit to regulator. 2) Wait for the solar panel to charge the capacitor up to 12V 3) Upon reach 12 V, allow the current to pass thru regulator again. Repeat step 1 I tried so search Schmitt trigger circuit but I cannot find the suitable one as most Schmitt trigger  is with a Vref and signal input. Since my voltage input(capacitor charging and solar panel) is variable, I do not have Vref. I still believe it can be achieved, perhaps my mind stuck at one concept only

Solar Panel Battery Charger

I'm doing a solar panel cell phone battery charger project for school using a 9V, 3.3W solar panel that I bought from here: http://www.ebay.com/itm/3-3-WATT-9-VOLT-SOLAR-PANEL-3-3W-9V-Monocrystalline-Solar-Panel-/130612072684?pt=LH_DefaultDomain_0&hash;=item1e691610ec (I can get around 8V under a light bulb and 10.5V under sunlight.) The circuit is shown in the picture with four, 1/4W resistors because the output is going to a USB cable. The regulator I tried at first was a 7805 from radioshack I noticed I was getting exactly 5V on the output, but only getting 1.5mA of current on the output of the regulator. I've tried the MURATA 78SR, Fairchild LM317T, N.S. LM1804IS, and a few others specifying 5V and 1-1.5A of current but I still only get 1.5mA of current on the output (I need at least 500mA). The phones I'm testing will charge, including a ipod classic, but I'm afraid that the 1.5mA of current is far too small and will damage the battery. I have yet to try using 3W or 5W resistors but I still don't think it would help, I'm also considering using a boost converter to get the current up (also the voltage) and then feed that output into the 7805. Am I doing something wrong? Can I get around 1A of output current from the 7805 by doing something else?

Control panel switches connections?

Hello everyone I need to build a control panel with different switches so that I can control different devices or even all devices at once.  So I have already drawn a plan on what I need to do but it is just that I do not know how to wire the switches so that they can do what they are supposed to be? I need to know how to connect  everything together to have the right circuit First when power gets into the system there is a main switch that will allow power into the whole system. Second there is another switch that has full control over all the devices connected meaning when this switch is used all the devices connected will power on or off regardless of whether the other switches are on or off. Then there is the panel where there are individual switches located and each individual switches controls one type of device such as light or pump. Timer can also be used to be attached to some switch that can be used to allow some devices to power on and off about a specific time. Intermatic sensor can as well be used to power specific devices at night. Thanks for the help.

Non-permanent wall paneling?

So I got the idea from this photo: http://ak-images.jackthreads.com/v1/image/969357/size/jt-product_zoom I was thinking how it'd be neat to put some kind of wood paneling like this around my bed, maybe toss some LED strips along the top for an added effect. I'm trying to figure out a way to do this that won't be too expensive nor permanent (I'm renting my place so I need to be able to easily remove it when I leave). My thought was I could get the wood, stain it and then just screw it into the wall along the corners (or maybe even nail it if it's thin enough?) My alone concern with that are the screws/nails will look out of place, unless I'm able to stain them as well? If anyone has any other ideas on making this happen I'd really appreciate the help!
