Hello sir, Im intrested in solenoids feild and wanna have practical experince in that.can you please tell me how to generate electrical charge by using solenoids and storing that charge in mica capacitors with less voltage rating high storage capability..which also has slow discharge. The time of storing the charge should be high.Hope will guide me. Thankyou. Raghudeep,

I have 50 meters of uninsulated copper wire 20 gauge. I want to make 4 solenoids out of it, yes i know i need magnet wire or insulated wire but they don't sell it where i live (Mississauga, Ontario, canada) so i was wondering if i can use electric tape (vinyl electric tape) to insulate the uninsulated wire and use it to make solenoids. first time on instructables so i apologize in advance for any mistakes in this posts. Oh and the metal object needed inside the solenoid that goes in and out (idk what its called) can i use canadian pennies and apply hot glue to make a long rod? would that work? i don't need the engine to push anything heavy i just want it to work. Thanks

I bought something like this off Ebay: http://g02.a.alicdn.com/kf/HTB1S5xyLpXXXXcGXXXXq6xXFXXX1/New-Fashion-DC-font-b-12V-b-font-2A-Pull-Type-Linear-font-b-Solenoid-b.jpg Turns out it wasnt as powerfull as i need it to be but it has the right amount of travel and is nearly perfect in size... Notice that the body where the coils are is fairly short. What if i made my own? But MUCH longer body, (theres plenty of room in my aplication LENGTH-wise) will it get more powerfull? Can i make it more powerfull by adding more coil? Turns out i have plenty of coil like the one used in my solenoid, i have plastic pipe similar size and i can CNC the central "plunger" rather easy as well. Or make it different shape etc... The solenoid i have has a metal body, does that affect how strong the solenoid is? The coils are wrapped around a plastic tube, the plunger is rather loose inside it and the tube could be thinner. Will thicker plunger and thinner tube improve the power? Im using a 11.1V lipo battery, something you can find in RC-cars. Increasing voltage/amps IS NOT AN OPTION. So, in simplicity, if i make a solenoid like mine, but longer, can it pull greater load than the original or do i need to do something else as well? The actual aplication itself in simplicity is the solenoid pulling certain object back around ~10mm AGAINST a spring, not very powerfull spring might i add. It pulls the object back, then lets go. It will be controlled via a circuit later but right now just a battery and nut-job holding a red button. I just need a solenoid powerfull enough to overcome the spring. The object needs some force to return to its position so putting in a smaller spring is not an option eighter.

Ok guys so Basically I have a plastation 2 console in my arcade machine, I want to be able to turn it on via a arcade pushbutton on the outside of my machine. The idea I have is to use a linear push solenoid to act as a finger to press the power button on the front of the ps2 everytime i press that pushbutton........ Is this possible? what type of push solenoid do I need....eg. 12v? size etc.... and can I use a momentary contact pushbutton to power on the solenoid momentarily to do a single press of the playstation 2 power button? Thanks for any help... P.S. I have very little knowledge of robotics or servos and solenoid usage....but I can solder, wire, etc....

Hello! :) Newbie here (and to using Arduino). Sorry in advance for the dumb question: If I'm using an Arduino uno to control three 12V push-pull solenoids, how much external power do I need? I tried using 3-12V power supply to control 1 solenoid only, but it didn't work. FYI, in the circuit I'm also using: - TIP120 transistor - 1N4004 Diode - 1K resistor (don't have a motor shield to replace all of the above..) Not sure where I'm going wrong. Could anyone help me please? Thanks!

I'd really like to replace some LED indicators with physical on/off indicators, like they used on old NASA spacecraft. To see what I'm talking about take a look at this console from Apollo 14 at the little windows above the switches at the center left. The top row is all "barber poll" the bottom row open.My initial thought is that I could possibly replace the LEDs with a solenoid that would shove an "on" indicator into a little window when powered, and retract it when powered down.The problem: I know next to nothing about solenoids and don't know if this is feasible. They'd need at least 1/4" throw and to run at low power if they're going to simply be a drop-in replacement for LEDs. What kind of solenoid am I looking for and does it even exist?

I'm trying to build an electrically controlled coin dispenser (all the coins will be the same type). I have a metal tube -just the right diameter for the coins - mounted vertically, with a piece of wood horizontally at the bottom. There is a gap between them of approx 1mm, just enough for a single coin to be visible. I've been experimenting with using a solenoid to swipe a coin from the bottom. Rather like the image here: https://www.instructables.com/answers/Petty-Coin-Bank-Design-Coin-Dispenser-What-shou/ Solenoids aren't cheap, and I was aware that the weight of the pile of coins (I'd like to be able to hold around 100) would mean it needed to be fairly powerful. In the end I bought some cheapo solenoids from ebay (around $7 each). They are rated 2A and have a hold force of 20N - this seemed a lot more powerful than I could find elsewhere for even 10 times the price. Given how cheap they are, I could even use two in parallel if I still need more power. I'm using coins with a 20mm diameter, but after the solenoids arrived I realised they only had a 10mm stroke - obviously not enough to fully push the coin away. I've tried using the solenoid to pull a lever, but this doesn't seem to work very well. Previously I'd also tried a stepper motor linked up to a disk with a coin-sized hold cut on it, rather like this: https://cdn.instructables.com/F49/GK0I/H703O9VD/F49GK0IH703O9VD.RECTANGLE1.jpg That worked pretty well but was very slow - it would take 3 or 4 seconds to dispense each coin. So, I'm looking for a bit of advice. Would I be better off splashing out on a more expensive solenoid with a 20mm+ stroke? Am I approaching it the wrong way?

Folks, I recently purchased some inexpensive 110Volts AC solenoid coils from China through eBay (of course.) As I understand solenoids will convert electricity into linear motion. I have been unable to do that. I tried ferrous rods as plungers, they get stuck inside the walls of the coil's cylinder. No ferrous material like aluminum rod did not work at all. Can someone please guide me to make it work. I purchased 110 Volt coil thinking that it will create a stronger field, I don't feel the strengths of magnets to be rather weak. 1. The coil gets hot when energized. Will it burn out if I keep the solenoid energized for 4-5 minutes? 2. Should I go for a lower voltage DC coil? 3. What happens to the dc coil if energized for long time? I would greatly appreciate your comments. Thanks.

Hi, im wanting to build somthing simple to control the heater control valve on my fiesta. its a simple solenoid valve at 0v its open(hot) at 12v(14.4v) its closed(cold) the propper control board uses pulses to control the valve, the board has since given up and im left with a very hot car, now i thought a simple way to sort the problem might be to use the 10k pot on the control board with a MOSFET and just vary the voltage going to the valve. will this have the same effect on the valve?

I have a setup in my mind, consisting of a plastic bottle(filled with water) with a male threaded neck. This bottle is sitting upside-down so the threaded neck is on the bottom. I want to transfer this water to a cup(by freefalling water) through an electrically controlled solenoid valve. The problem is, the plastic bottle I have picked out has a neck outer diameter of 1-1/2 inches, and assuming I want to directly connect the solenoid valve to the neck, I need to get a 1-1/2" diameter valve, which is above $100. Is there any way to connect this container and a valve(still not picked out) without that high a cost? Maybe a reducer of some sort(i looked but cant find any with 1-1/2" diameter on one side)? Thanks guys, and sorry if the question is kinda weird and simple. For a reference, check this project. https://www.instructables.com/id/Robotic-Drink-Mixer/ What i want to do is similar,but instead of using a pump, I want the water to freefall into the cup.I'd like to eliminate the tubing too.

I will have four of them evenly spaced over four inches (They need to be no wider than an inch, would much prefer they be less than a half inch in width. Height isn't important, and length should also be under an inch.) They also need to be fairly weak, i dont want one of them punching a hole in my tablets screen by accident. Doesn't need to be controlled by PWM, either off (Not touching) or on (Touching) will work fine. Please do leave links along with the name of the device/part.

Hi, I have an air supply and, thanks to iceng, a rapidly pulstating (variable speed) 12v Dc power. I would like the air supply to allow through a set amount of air each time. I already have a mechanical switch that works perfectly, allowing the exact amount of air through, I need this air switch to be opening and closing as quickly as possible. Would I be better of using a push solenoid and setting it up with the switch or do you think I will obtain faster speeds using a dedicated solenoid valve? I was looking a this solenoid.

I have a closure system with deadbolts that works on a sliding assembly with a solenoid that turns 180-deg to close and the other 180-deg to open. It is accomplished with two limit switches (as shown in the picture attached). My question is I have a single control button. If I press it once -- I need it to trigger the power in conjunction with one of the limit switches (to stop the solenoid at the appropriate time) and then on the next press of the button, send power through the other limit switch so it cuts power at the appropriate time. Obviously if I wire everything at once you have one switch open when the other closes and vice versa so power continues. My question is this. I believe I can use a 4017 chip to allow power to go to one and then the next with each press of the button. However it seems like overkill and I figure that there has to be a simple one-two power diverter switch of some kind that I can put between the button and the solenoid/limit switches so it cycles between the two. In other words. When power comes through it the first time, it routes it into limit switch #1, the next power cycle goes through to limit switch #2, and back and forth. Is there something simple like that. If so please share. If not, can someone please tell me the best way to wire up a 4017 chip for this purpose. As always, thanks in advance for any experience, advice and/or wisdom -- it is greatly appreciated.

Ok, I need a power supply for a solenoid. It is to simulate the kick of a pistol. I need a power supply that is small, so that I can hold it in my hand without being to heavy to hold for a long time or it being uncomfortable. The solenoid will have a neodymium rod made of lots of 6mm*3mm neodymium magnets inside it. The coil is 5cm long with 0.8mm ECW and 7 layers although it can be rebuilt. The point is that I need something to power this coil and let the neodymium magnets hit the wall behind the coil (wrapped around a 6mm tube) and produce a sort of kick. The power supply needs to run on a roughly small power such as two nine volt batteries (dc). This is a long question but I would greatly appreciate any help. Thanks :) (I have a circuit to make it produce recoil (electic bell...) but how will I power it to be powerful enough!?) Thanks again!

Hello. I made my own (extremely basic) remote-controlled door lock a few weeks back. It consists of a couple of solenoids, a remote controlled pass-through plug socket and a shaver adapter (lol) The RF remote turns the plug socket on and the plugged-in shaver adapter carries current to the solenoids which causes them to retract so I can open the doors. I can also use the remote to turn-off the plug socket (thus releasing the solenoids, locking the door if the door is shut) But the problem is that sometimes I forget to turn the system off and the (still-retracted) solenoids get hot after 20-30 minutes, which is an obvious fire hazard. So I'm looking for a timer that will shut-off the system after a few minutes. I've seen plugs on eBay that are designed for hair straighteners and turn connected devices off after a set time, but they all operate at 30mins+ and most require you to push a button to set the countdown timer, which is just completely useless for me. I want a timer that starts as soon as it's powered-up and shuts down the solenoids after a couple of minutes if I forget to shut them down with the remote. Any ideas where I could get such a thing? They're operating (via the shaver adapter) at 4.2VDC if that helps I've included a photo of the RC plug and shaver adapter in case I didn't explain it very well xx

Hi, I have in my lab room thick tinted copper wire. I planned using them to make some electromagnet, but fail to find a solution on how to insulated them. At first I thought using those acrylic/enamel can spray, but I am not sure if it would fully insulated them. Would the acrylic/enamel penetrate between the contact gap and insulated them or will it just fail to do so? In fact, I am not even sure if it's a good idea to begin with, because I don't want to actually waste the copper. As an alternate option I thought using those magnet wire from the Microwave Oven transformer, the one with really thick diameter. I would uncoil them, and manually turn them. I thought I could use some of your advice. Actually, I dont mind if the process takes time, I am just looking a convenient way. Thanks Richard

Hey guys, new here. Been looking around for parts for my project for a while now and so far have come up pretty empty handed. I am looking for some parts, or even some information on if anyone has a specific place for parts when it comes to household plumbing. i am trying to source out Variable water valves of the analog variety in 1/2" or 3/4" inlets (preferably in brass) to be controlled by an Arduino. They need to be able to handle a PSI range of 80-100psi and in a N/C state. $0-$30/each preferably Without fully giving away my project idea I basically am looking to switch out manual hot/cold water taps with electronically controlled ones. I need to be able to adjust how open the valves are so I can vary the temperature between the two pipes so that I can get an Arduino to control (with other sensors) and get a water temperature out the drain that is equivalent to bath water. (Hence why I need them to be variable and not just on/off) I have have checked local shops, asked plumbing friends, alibaba, and (of course) Google. And I just can't seem to be able to punch in the proper keywords to find exactly what I am looking for. The closest thing I can find is automatic sink tap solenoids but they require a manual set up and only output at that mix ratio, So I'm hoping that someone has a plumbing supplier to direct me to, I'm pretty much out of ideas. thanks in advance!
