Delayed again!!!

I have been working on my plasma speaker for a long time, after I got everything working, I was about to take a good video of it working. But just then, the MOSFET exploded, and made a huge puff of smoke... Dang! Delayed again! I made and completed the instructable on making a plasma speaker (some of you might had seen it as you are subscribed to me), but I just need a video to prove that the plasma speaker is working. I was going to post the instructable today, but the MOSFET delayed it... :-( It may be a few more days before the instructable is published...

DC time delay? Answered

Here's the situation-I close a switch completing a circuit,providing DC power to a load(6 volt,0.1 A).But I do not need the load to start functioning as soon as the switch is closed i.e,only after a delay of say..30 seconds.I googled for "Time delay circuits" but the ones I got were either dealing with AC or the transistor -capacitor(Time Constant) based circuits that makes a load function for a preset time after the circuit switch is opened.I think I could achieve this "pre-delay"  with elements such as transistors,resistors,capacitors etc. but I can't figure out how.Please suggest possible circuits that can be used to achieve my purpose.

Question by Adarsh_tronix   |  last reply


I love baseball.  I want to watch the World Series on TV, but I don't want to listen to the TV announcers.  I want to listen to the radio broadcast instead.*  Problem is, the "live" TV arrives 1-2 seconds after the radio.  Which means I hear about the deep flyball to left before I see it. And that takes the fun out of watching the game. So, I'm wondering if I can add an adjustable delay to the sound from my radio, to sync up with the picture.  I can sacrifice a boom box or other radio for this if nec. Or some other solution? (I can record both and sync 'em up later using video editing software, but that's not practical). * for baseball fans:  it's the choice between the Buck/McCarver team (perfectly boring & perfectly obnoxious) and Jon Miller/Joe Morgan radio team (passionate and fun).

Prize Shipment Delays

Hi everyone! If you have won a contest in the past month or will win a contest in the next month or so, there might be a slight delay in shipping your prizes out.  You might have noticed that we are hiring a shipping clerk, that's because we need one!  We are a little understaffed at the moment and we are shipping out for prizes as fast as we can, but unfortunately we are only human!

Delay for a timed switch?

Hi, I wont explain my purposes(maybe in an instructible if i get a good answer) but I need a simple(as in, requiring very few parts) schematic for a 555 timer. I need a setup where i have a battery, connected to a switch(the kind that you push, and it closes the circuit, then you push again, and it opens the circuit. I forget what its called) that goes to a 555 set to delay for 10 seconds. After the 10 seconds is up, it allows the electricity to go through. Anyone understand? If needed, I can upload a pic of what I need.

Time delay LED

I have something I want to make, but I don't know what I need, how to make it, or what it would be called. Essentially I would like to have a few LEDs on a programmable/resettable timer. I.E. One LED would be programmed to say 3 minutes, 30 seconds from the 3 minute mark it would slowly start to light up then flash when it hits the mark. I would also like to be able to start/stop and reset the timer. I need a couple of them, and wiring the LEDs are simple enough, it's the time delay that's throwing me. Any assistance would be great.

In a dark corner

What do you do when you publish an Instructable that would be helpful to many, but its posting is delayed several days. When it finally appears, there are five pages of newer Instructables and no one ever finds yours in the "Recent" listings? Do you unpublish and republish it, hoping it will get moved to the front of the pile? Does that even work? Do you shamelessly make comments leading others to it in previously published Instructables that are still gathering some hits? Do you just wait until people discover it somehow through using Randomizer and a link or two on Google?

Ible delayed posting no longer new.

If you have an ible delayed of being posted for who knows what reason. When it gets posted it gets posted in the spot that it would of been  originally. Example, on 6/1 i published 3 ibles in one day. One posted in 10 minutes. The other 2 posted on 6/4. Now the two late posts do not get put at the top with the new ibles, no it gets put in at the date it was first submitted. My variable voltage supply took 6 days to post. So to find it you have to go through many pages of ibles to locate it. IT does not get posted as the newest ible. I had sent a msg to service@instructables but never did get a real person.    If peoples ibles are delayed for some flagging issue or what ever it would be nice to know what to avoid in the future. I have gotten a tip on some issues that may trip the filters, short keywords, not common or unrecognizable keywords. Such as eek. In msg or forums delays maybe from short question with active links.. These are tips are from someone that has been observing these things and are not a locked in rule.   Altho these are somewhat of gripes it is not anything that will stop me from posting ibles. I realy gain from Instructables. Before i joined here i never heard of Arduino now i am writing small sketches and manipulating larger ones.

off relay with delay on timer

Hello smart people! I need to pick your collective brain. The project that I am working on is on my car. I am replacing the front turn signals on my car with an LED strip. The led strip has three wires. One for ground, one for white LEDs, and one for the amber LEDs. If it is just directly connected to the current incandescent bulbs, the white comes on as a running light. When the turn signal comes on, the lights flash white, amber, white, amber..... (not what I want) What I want it to do is turn off the white while the amber flashes, then turn the white back on. I have a delay on relay, but that won't quite work for what I am trying to do. Isn't there a way to just throw a cap and resistor to keep the voltage on a relay to keep the white off till the amber is done flashing?

Two DPDT switches with timing for one motor Answered

Hi, I have a motor (12V DC) that I need to be able to operate both backwards and forwards from two locations. The simple way is to connect it with two DPDT switches with momentary on in each end and off in the middle, i.e. also called (on)-off-(on). The reason for using momentary switches is that there would otherwise be a risk of short circuiting if one of the switches are left in on-position. However, I almost always need the motor to go to preset limits in both directions which takes a couple of minutes (the limits are built-in functions in the motor, so no need to set those). So I was wondering if there was a cheap and easy way of inserting a kind of timer or similar that would only leave the connection on for a couple of minutes only (and yes, there would still be a risk of short circuiting within those two minutes, but it would be unlikely to happen)? Or perhaps there is an even simpler way of doing it? Any ideas would be welcome. In (the likely) case the above is not clear, perhaps this will help: I need it to operate a curtain, i.e. moving the curtain up and down, but I need to be able to do that from two different locations. Preferably it would be good if I could also stop the engine somewhere in the middle - as I would be able to do with a switch simply be releasing it. The best/cheapest/easiest way would, I think, be to have two DPDT switches with a spring or something with a couple of minutes delay, i.e. if it is left in the on-position for more than two minutes it would automatically spring back. But such a thing seems not to exist... or? Would be grateful for any inputs. Erik

Arduino Coding Question: How do I blink one LED 8 times and then another LED 8 times then repeat?

I'm using two 4017 decade counters to count to 16 and I figure two Arduino outputs would be a good way to go. I want one 4017 to receive 9 pulses then and then wait while the other 4017 receives 9 pulses. (one pulse is a holding position) For the moment I'm just trying to blink one LED 9 times and then another 9 times to represent two separate clock outputs. Here is a diagram: pin 13    1, 0, 1, 0, 1, 0, 1, 0, 1, 0, 1, 0, 1, 0, 1, 0, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 1, pin 12    0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 1, 0, 1, 0, 1, 0, 1, 0, 1, 0, 1, 0, 1, 0, 1, 0, 0, Start      ------------------------------------------------------------------------------------------------------------ then loop. This is for multiplexing a 16x16 led screen so I don't think I should use the  delay(1000);  command. Each counter needs 9 pulses with the last pulse to the first counter happening simultaneously with the first pulse to the second counter. And similarly the first counter getting its first pulse at the same time as the second counter gets its 9th pulse. Get it?

Simple on/off delay switch circuit

Here's what I am trying to do. I am already controling 4 LEDs with a 9 volt zener regulator. I now want to control the source of the regulator (ie voltage from the battery on board my motorcycle) with an electronic switch. Not a big deal, but I also want the voltage to the LEDs to ramp up slowly so that when they initially turn on, they are dim, but get brighter and brighter until they reach their 9 volt regulated source. Then when I turn the motorcycle off, they fade slowly until all the way off. So I guess is what I want is a delay switch. Should I be switching the 9 volts regulated to the LEDs or should I switch the source to the regulator? What is the cheapest and easiest way to do this? Any help would be appreciated. Thanks.

I mean, ideally my "Discussions" tab would notifiy me of replies in a matter of hours, so I could reply to those replies in a timely fashion, if it was the sort of thing where someone was expecting a reply from me.I am guessing this problem was maybe related to the recent big "improvements" to the site, to make it more readable for mobile lusers, and other changes to make the site more comment-able, question-able, tip-able, by everyone.Just wondering: Has anyone else experienced this same problem, i.e. a several weeks, or months, delay in notifications of replies to your comments?

Day/Night sensor with 3hour delay?

Hi! I need to build a circuit for a friend. He has a billboard that needs to be lighted every night, but it needs to be lighted only for about three hours (until he closes shop).  The only problem is, there is no way to get mains power to the billboard, so we figured that we'd set a small 12v battery, solar cells, and some led tape, that would be enough.  Now all i need is a 12v circuit that would detect low-light conditions (night) and would turn on a timer which would turn off the whole circuit after 3 hours. I searched the net and my local electronics stores, but couldn't find a circuit that would suit my needs...  So any help would be greatly appreciated!
