Something is causing a delay when I switch pages

When I switch pages in answers there is a 7 second delay.  I'm using Firefox 3.62 and it does this on two systems running on different providers. If I go to a question page the page comes up and I don't have control of the cursor for 7 seconds.  The only error message I've been able to see said there was a script that was not finished.  I've checked for virus and malware.  When I go back to the main questions page the same thing happens. Does instructables have a broken script?

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).

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.

One shot delay timer switch without a microcontroller?

How do you output a single short pulse in an electronic  circuit after a specific period of time has elapsed after the circuit is powered on such that when the circuit is powered on, the output remains zero for x seconds then it becomes +5 V just once for y seconds then again back to zero for the remaining time much like monostable mode of 555 timer except that the pulse here is output in the middle i.e. 0v-5v-0v.

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.

Filtering spam is good of course but geez, i made a comment in the forums of a current bug problem and guess what my comment is not there . I can only say it is because of the filters. Maybe my comment will appear after the relevance of the topic is over. There needs to be a filter list added that puts the known non spammers into. The people that are submitting ibles and or comments that are not spam. You go ahead and make this secret like it is now so people won't complain about who's on it or not. The people that are your supporters should be in the Good Filter, let there ibles and comments submit without delay. So i am in favor of a GOOD FILTER list.

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

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?

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?

Sentry Gun and PIR sensors

Hello, I have a question about PIR sensors for a robot I'm making. Most have a digital pin that goes high when movement is detected. The time that this pin stays high for (delay time) is often adjustable by a variable resistor on the sensor. My problem is that I need a sensor with no delay time - the digital pin should go low as soon as movement stops. If anyone could point me in the direction of a pir sensor with no delay time/one with a very short delay time (under 0.5s) I would be grateful. Or possibly, If I were to remove the variable resistor, would that remove the delay time? thanks.

Looking for help making a simple on/delay/off circuit.I? Answered

I am looking for help making a ( hopefully simple ) circuit to drive an electronic relief valve. What I have is a push button on a linkage and an electronically actuated valve. I'd like a circuit that, when the button is pressed, will supply a 12v output for roughly 500ms immediately after the button is pressed, which will then turn off. The circuit must then remain off while the button remains held, until it is released and hit again.  Linkage open / Valve closed > Linkage closed / Button pressed > Valve open 500ms > Valve closed / linkage remains closed > Repeat The system is for a turbocharged diesel engine. When the throttle is snapped shut, the boost pressure has nowhere to go. It tries to run back out the compressor housing. This results in a forceful drop in turbine RPM, and in extreme cases even completely stalling the turbine ( and blowing it to pieces ) I intend to vent this pressure back pre-turbo via a 2 inch valve. The short delay upon closing the throttle with this size of valve should be more than adequate. I also intend on wiring a boost pressure switch to disengage this circuit below 15psi. The turbo's anti-surge housing is effective at the lower pressure. Any help with the circuit would be GREATLY appreciated!

Filtering queue question/suggestion

Please correct me if I've mis-observed this, or if it has already been addressed. When I use Instructables, I always use the "Recent" option to browse recent Instructables. Often, when I look again after several hours or days, new Instructables have popped up, interspersed with ones I had viewed previously. So, when a new Instructable gets hung up in the filters, am I right in observing that it then gets inserted (when it is released) "back" to the time when it was originally published? It seems that it would be better to post it (chronologically) when it was released from the filters, rather than, in some cases, a page or two back.

Grounding Issue in DIY Circuit

Hello everyone, I'm having a bit of a problem getting my LM317 soft-start circuit to function properly. If you'll take a look at my schematic, I've built everything on the schematic up until the relays and diodes get involved (specifically where the output forks into two). In order to check that I soldered the board correctly, I hooked an LED up to where the fork would be to make sure the soft-start worked. Here's where things get funny: If the LED is connected to the rectifier's negative, the LED behaves as I expect it to, with a slow turn-on. However, if I keep the LED connected to the same positive point, but hook the led directly to ground, nothing happens. In fact, using a multimeter showed that no voltage would flow to ground from the positive, but that 14 volts were flowing between the same positive point and negative. I need voltage to flow to ground, this is a ground safety interlock for a welder I'm working on... does anyone have any suggestions? Thanks for reading :)

Timer gadget to press a button (on a dishwasher)?

Back in the days when appliances had real dials and switches on them, you could set the program and then put it on a timer switch so that it would run on off-peak electric. Now that they're all software controlled with soft switches you can't do that unless you either pay a premium for one with a timer or if they have memory to resume the program from a power cut. What I'm looking for is a simple little thing with a timer on it that you stick over the top of the soft power button, and it will press it (unless you can trigger a soft switch like a capacitive switch by sticking a voltage in front of it?) when the timer runs down. Is there a little gadget to do this? or does anyone have plans to build something? I know I could hack a timer into it fairly easily but that would mean voiding the warranty. Any help would be greatly appreciated, thanks.

When i use my simple led chaser program led5-led7 lose power and are very dim. all leds have different pins, same ground ,and the same resistors here is the code can you tell me what is wrong thank you int led1 = 8; int led2 = 9; int led3 = 10; int led4 = 11; int led5 = 3; int led6 = 4; int led7 = 2; void setup() { pinMode (led1, OUTPUT); pinMode (led2, OUTPUT); pinMode (led3, OUTPUT); pinMode (led4, OUTPUT); } void loop () { digitalWrite(led1, HIGH); delay(99); digitalWrite(led1, LOW); delay(99); digitalWrite(led2, HIGH); delay(99); digitalWrite(led2, LOW); delay(99); digitalWrite(led3, HIGH); delay(99); digitalWrite(led3, LOW); delay(99); digitalWrite(led4, HIGH); delay(99); digitalWrite(led4, LOW); delay(99); digitalWrite(led5, HIGH); delay(99); digitalWrite(led5, LOW); delay(99); digitalWrite(led6, HIGH); delay(99); digitalWrite(led6, LOW); delay(99); digitalWrite(led7, HIGH); delay(99); digitalWrite(led7, LOW); delay(99); }
