Posted by MR.J67 7 years ago
I have a great idea and looking for a type of DC electric control that can handle a charging system and power release . IS THIS POSSIBLE !! and can there be a program written that can control the amount of dc power released? of course i want to control multiple incoming power sources and release the energy it creates. ANY AND ALL IDEAS WELCOMED!

I think it would be beneficial to create an A/V switcher that has power plugs for each of the slots in addition to the a/v components. So if you select #2 for example, it would power only #2 as well as display whatever is plugged in to #2. Could someone create a tutorial for this? Thanks

I am wondering if there is a way to use solar energy to power a room through solar power. I have an attic space that I would like to finish in my home, however, I think it would be cool to use solar panels, inverters and batteries to power the rooms (electrical outlets and lights) is there an easy way to do this?

I built a PSU bench power supply, but it isnt outputing the right voltages. It just out 5v for all lines(12v,5v). It has a purple wire that is said to be the stand-by, but the psu wont start unless it is connected to the 12v or 5v line. It also says that you have to have the brown sense wire attached to the 3v wire but this seems to do nothing. How can I make this thing output the right power(12v @ 22A, 5v @ 50A)?

Hello all ! I'm new to instructables and Iâve found some cool and helpful information for my projects. I need a bit of help designing a power supply voltage reduction device. One that accepts 9v input and output into two 3v 5mA outputs. I want to replace the batteries in a/b Boss selector with a more reliable source of power.

Hi all. I have a really old dell laptop(given to me) that is missing a power supply. It requires 20v and 3.5 amps to run. I want to make a digital picture frame out of it. I wont be using the battery or cd player and maybe not even the hard drive(not yet decided). Any idea's on what to use as a power source? I don't need to charge a battery just need power. Could I use an old pcu? I know that I could combine the two 12v lines to get 24 ish volts but won't that fry the old thing? I don't want to buy a replacement power adapter cause it is so old and may not work anyway(plus I wont lie I'm cheap lol). Any suggestions?

I have been toying with an idea for a while of making permanent holiday light fixtures with individually addressable LEDs. The problem I continually run up against is that these types of LEDs all run on 5v power, I believe because of the driver that controls them. They have high voltage AC strips, but they aren't addressable. If I take Adafruit's "Dotstars" as an example, they require 60ma of power per led at full brightness. A typical holiday display may require up to 250 feet of lights. If those lights are spaced at a typical 2.75 in apart that's 1091 lights. This becomes 65455ma or 65.5 amps of power. That's a stupid amount of power required for some holiday lights. Are there any high voltage individually addressable leds on the market? Is such a thing even possible? If not, is there some type of wallwart that might help me solve this problem in a safe less power hungry way?

Hi- i have an ION electronic drum kit that i got from a friend, but i somehow managed to lose the power brick. It wants 9V AC & 850mA, which for the life of me i cannot find anywhere. So, does anyone know where i can find one, or if there is something else that might work? Thanks a lot.

Would it be possible to run multiple cordless drills off the same power source? I do not want to run the drills all at once, but rather have them share the power source. I was thinking of modifying an ac adapter with a voltage and amperage less than the tolerances of the drill. Are there any safety concerns? If I do this will I blow myself up? Could I run them at a higher voltage/amperage? Is this idea dangerous and stupid or just stupid?

Hello, I have a little sub woofer box and 4 speakers connected to it, it has a line out 3.5 mm headphone jack which i connect my iphone to, the Subwoofer box has a power cable which plugs into the mains power. This is for work and it does the job just fine. my question is though i want to put a USB socket in the subwoofer box so i can charge my iphone at the same time via USB. Can i splice my usb socket extension cable into the power cable?? The power cable does not have an AC adaptor on the end if it just the plug. If this cant be done How can i get power to usb. Thanks in Advance.

I made this mini powered speaker box to use with my laptop because the built in speakers suck on my ACER (great laptop just crap speakers) right now its powered by a INPUT: 120VAC 60Hz 21.6VA OUTPUT: 9VDC 700mA power adapter anyone have any ideas for a portable power supply so it doesn't require an outlet? I'm trying to keep it portable. right now it fits neatly in my laptop bag and sounds great, there's even an input for a Sub when I'm at home. I'd like to go USB if there is any way........ but I'm open to battery ideas P.S. if people like it let me know and I'll post it as an instructable ...... I've seen many speaker ibles on here so I wasn't gonna post it unless people want it

Hi Again, My question is when building an ATX power supply, Can you join the 12 volt leads with the 5 volts leads to make 17 volts? If not how can I get lets say 20 volts. I am going to use a DC to DC converter to make a variable power supply. I would like at least 20V in then I can adjust from 1.2 to 60 volts out. I use it now running directly off battery but would like to add it to the ATX build case. Thanks for any help again.

Blake Bevin wowed us with the Power Laces Instructable that brought a bit of Back to the Future Part II to life. Thanks to the massive reception from the project she has decided to take the idea quite a bit further and make it a real product for sci-fi fans and people with motor skill disabilities. The new development will require some money and so Blake has turned to Kickstarter to get funds for the project. So if you want to support a fellow maker and help these things become real, kick in a few bucks to help it get going. Power Laces Kickstarter page via engadget

I know this is a long passed DIY. But while building a ATX Power supply I separated all the wires as stated. I then put the green and a black wire to a switch and added the 3 brown leads to the orange leads. When I plug in the unit the supply light comes on, but when I turn the green wire switch the main power LED goes out and no fan comes on. It acts like the switch is shutting the unit off. Can anyone help. I am 60 years old and just getting into doing some bench work to pass the time. Thanks for any help.

I am building a garduino since planting season is coming near and this would be a great to start me seedlings off in. right now I have 3 banks of three red leds rated at 1.8v and in one of he instructible they said 7v was sufficient but i am connecting a 9v and can only power 2 leds and also I would like to go with an ac-dc converter but everyone i found has at least 800+ mA can someone point me toward a good power supply at the end I am looking at about 25 red and 8 blue LEDs

I have this 6-volt Lamp it's kind like what you would find in one those 6-volt flash lights except that this is like a stand alone lamp and it has two wires that come out of it but only seems to work at 6-volts, so I have a large 6-volt battery and a 7.5 volt output power adapter I was wondering if 7.5 volts would be too much power to use to power the lamp I don't want to blow it up. I don't know if it'll even work at 7.5 volts because I tried a 9-volt battery and it won't power on with it. The image is the same lamp I have except mine is connected to a base and has two wires that come out the bottom I would like to find another way to power it besides using a large 6-volt Battery. Any Suggestions.

Power beaming is just another way to say solar climbing. This is a competition hosted by The Spaceward Foundation. The end goal is to design a structure that will transport material from Earth into space without using rockets. The competition requires you to build a climber with the specs that follow:"net weight is limited to 50 kg [110 lbs], and they must ascend the ribbon at a minimum speed of 2 m/s. [6.6 feet per second] carrying as much payload as possible. A high performance prize will be awarded to teams that can move at 5 m/s. [16.5 fps]"Remember, this must be solar powered. Doesn't matter who wins this is an interesting engineering project, can't wait to see what people come up with.Anyone interested?

First, I apologize for being (almost) the hardware version of a "script-kiddie". I do want to learn the techniques involved but all of the electronics courses I've found work the wrong way around. They teach "this is what we have and this is what you can do with it" whereas my brain works in the "This is the problem, here is a solution and this is why it works." manner. This is how I learned software but when you get it wrong you can start again without losing the magic smoke! I have a 250ah, 12V battery bank, multiple DC devices requiring power and, eventually, several power sources for recharging. I also have several MC34063 chips and a few higher amp chips (somewhat optimistically as it turns out). Firstly, is there a practical course online that is built around this? Secondly (and probably extremely basic), if a device draws, for example, 3A is it self-limiting or do I need to put something between the source and the device too restrict the power?

I would like to put a Challenge out there for anyone to come up with. You see, I am in a wheelchair and I would love to go hiking with my son, but my chair can only go so far before it needs to be plugged back into a socket. I hate this, because it keeps me from going most places I want to go outdoors. But it dawned on me that if I had a Solar Powered Option to my chair, nothing could hold me back from being outdoors again. Ok yah, it would help if I could redesign the platform & wheels too, but that's not the most important part... I NEED POWER. So, if anyone feels like taking on a new challenge and you are into Solar Power perhaps you could help me in this way. Thank You for your time in reading this, I hope to plant seeds of inspiration with all of you! May Love Light Your Way, Blessings!

Hi, I have 4x PANASONIC CGR18650CG LI-ION BATTERY 2250mAh 3.7v. I have connected them in series and it gives around 14v. My internet router is working on 12v 500mA. Is this battery pack too much for that router? I was thinking to use that battery pack as backup for my router when there is no electric power, because it's winter and every few days there are problems with power. Thanks!

Hi, I have a desk and I've put shelf on it that is 4 inches high from desk. On this shelf lie two 23 inch monitors. Below the shelf, tucked away, is my laptop (with the lid closed). The problem is that I need to be able to turn the laptop on without opening the lid. (The power button is right above the keyboard). My motherboard does not support Wake on LAN but it does support USB Wake. This is a bit useless to me, however, because it doesn't allow me to fully shut down the computer, but rather put in stand-by. So i wanted to know if there is a way to attach an external button (maybe a push switch) that can power the laptop? If so, can anybody help me out how to do it? I'd assume it would be in parallel to the regular switch. I have an Dell Inspiron 1521 (which I think is a fail to being with :P ) Thanks! AK

I have a question, I am thinking of making a Pepakura Iron Man mask for my father for his desk at work. I have big plans for this, but the biggest thing I want to do is had the Eyes light up. What all would i need to do this? I would think using LED's would be the ideal way to go. I dont really want to use batteries to power it, as I would like it to run off of a wall plug, and perhaps even have a switch to power on and off. Any ideas? I've looked all over, and I cant really find a deffinate way/means to power it through an outlet....most all just mention batteries. I know it can be done though :) Any help is GREATLY appreciated!

Clock idea = out!any other idea for a higher torque clock-like motorhere's a very very brief photo of my idea. The light gray is the rotatingfood area and would be push by the dark gray (white out!) motor. the yellowthing is a hatch. It was just for me to write my thoughts down and I know the hand will run into the wall and everything. The sloped rectangleis a ramp on the inside so the food turbine will move spilling down theramp into the bowl. Also the big hand is actually the hour hand, I drewa small minute hand to show it was a clock, This has it worked so it willfeed every 12 hours and needs to be refilled every day.I don't really need any critique just answers for now '"

Last time I tried to do my own homemade project I failed utterly, I think mostly because I had no idea what anything was (if you saw my last topic on a distortion petal, you know what I'm talking about). I decided instead to buy a book (Tab Electronics Guide to Understanding Electricity and Electronics by G. Randy Slone) which has projects in it, the first one being a power supply. I haven't started building it yet (waiting until I get back to the city) but I've started looking up parts. The thing is, I can't find a 4400-uF 50-WVdc capacitor anywhere! So my question is, can I just put two 2200-uF 50-WVdc capacitors in parallel to do the job of one of the 4400's? That isn't my only question, just the first which I'll ask later in this thread. Thank you (PS: Has anyone had a problem with using Chrome and entering text into these fields? I had to switch to Firefox to get it to work)

Okay so I understand the basic concepts of power generation but I have a question pertaining to the old addage: An object in motion tends to stay in motion. Resistance is power that stops any said object if it is equal to the energy of the object in motion - this resistance is from gravity and other outside forces acting upon said object. OKAY If the force to put an object in motion was then then collected by electrical generators from multiple other sources as part of the same object - would it be able to make up for the amount of resistance from the added collection and the amount needed to put said object into motion and keeping it in motion???? If an object is designed to be in motion then it does not require as much energy to stay in motion as it does to be put in motion. Even when affected by gravity, as it is affected by gravity less when is in motion. But can technology (bearings and rotors) be designed so they offer less resistance than the amount of energy required to keep said object in motion? This is impossible as far as I am aware. Energy is NOT free - but If the energy required to keep an object in motion is less than required to put it into motion, would not the true energy of the object in motion be greater than what is required to keep it in motion and be able to be collected as excess energy? Collection would result in resistance however and since the formula of "greater or equal force" applies collecting anything other than that differential in energy would result in the objects motion being slowed. Is this true? I am concerned about going into details on the nature of my concept until I can gain a better understanding of the science behind it. As such I apologize for how vague my questioning is.

I was going to ask are you caught in the blackouts I'm seeing on the news? Dopey question. Anyhoo, if you're reading this after the power comes back on, how did you cope? What Instructables could you use to make life easier? UPDATE: And, if you're an engineer, could you design a better system where a single throw of a switch on a substation blacks out five million people, shuts down two nuclear reactors and even closes beaches? The outage was triggered after a piece of equipment was switched off at a substation in Arizona, officials said. ... Daniel Froetscher, a vice-president at APS, told the Associated Press news agency the malfunction at the substation was "not a deliberate act". "The employee was just switching out a piece of equipment that was problematic," Mr Froetscher said.

I have a US plug AC/DC power adapter and need to get a European version. The specks on the adapter are input: 120VAC 60Hz 24 W and the output: 10 VDC 1400mA. I really don't have a clue as to what all these numbers mean but understand at a bare minimum I need something with a 10 VDC output. I've looked around at some shops and can find adapters that say 9v 1000mA and others that are 12v 1500mA. Do I need to get the exact voltage (I presume the v stands for volts)? What about the amperes ( I believe that mA is some increment of amperage)? Can I fudge the numbers a bit to save money and time instead of trying to get the exact configuration of the original adapter? Thanks for any help in clarifying this for me.

I need to move a small servo left and right and have it stay where I leave it and power 1 or 2 sets of lights with a simple remote but I have no idea how to achieve this apart from use a radio control transmitter/receiver and an electronic speed controller. I see there are lots of little devices out there that could work but being a noob at electronics I'm not too sure what will work. I found this, would something similar to that work? It is 12v, my servos would only take about 6v max though, same with the LED's, I suppose I could use something to lower the voltage output? Cheers.

So, I absolutely love the "Wireless LED Throwie" project here: http://mindtomachine.blogspot.com/search/label/wireless%20power videos: https://www.youtube.com/watch?v=p0-_ZX2oMyI https://www.youtube.com/watch?v=ieGOd2F_8MQ But there's some conflicting info (10uf capacitor in the parts list but 1uf on the pcb template, and pcb doesn't match schematic or what's shown in the video), and some info is just never given (transmitter coil diameter and number of turns). I want something like this where the transmitting coil is much larger than the receiving coils and can hold multiple, rather than the sizes being matched. I'm hoping somebody a bit more advanced than I am would be willing to tackle this first and take notes.
