Timing circuit - how to

Evening all, I am a NooB to electronics and instructables and would like to build a time control unit. What I am looking to do is build an auto baster for my smoker. The idea is to have a pump (ac pump or possibly a dc washer motor pump not sure yet do to the pressure needed) connected to a copper tube that  runs the length of my smoker. I want to have a time control circuit connected to the pump  where I can adjust the A) interval in which the pump is triggered B) the length of time the pump runs for. I have never done anything with electronics; well besides some radio shack kits as a kid however I do have some basic understanding. If anyone could help me or even just point me in the right direction that  would be great. Thanks,  -sunadmn

Timing system for 2 actuators

Hello all! I have 2x 12v actuators with 2 wires. I need to have both of them (at the same time) extend all the way and stay for 30 minutes and then retract completely for 30 minutes and cycle like this. What would be the simplest way for me to go about this? Cheers!

Does time of the entry matter?

Hi, Please note this is not a complain or anything of a sort but rather just a wondering, a question. I am not a total newbie here but I am also not much of an active user.  I am a busy leatherworker with no spare time for almost anything. I do love writing tutorials and helping others who want to know more about working with leather. When I write a tutorial I put my time and effort to make it really good so a person who follows it have almost none questions left. It does take a huge amount of time which usually leads to the fact that I enter a contest at the very last day/moment.   And here comes my question. Since the voting is open from the start of the contest don't those who entered in the beginning have more benefits/chances to win simply because they have entered early and so have more views/votes? I know there are those three days still open for voting after a contest is closed but this is a too short period comparing to the month or even more time available to the early birds. How does the entry time affect the selection of the finalists which from what I understand is based purely on viewers' voting? Do judges take into consideration the fact that the entry was at the last minute so could not get too many votes for the very same reason? Thank you! Era

Timing/warning device using Adrduino board?

Some time ago I bought some components with a view to trying to build a timer/warning device so that a boat driver can monitor session times on the water. To be honest I neither have the time or, as quickly became apparent, the expertise, to do it!! So I am posting on this forum in the hope that somebody may be interested in either taking on the project, or is able to put me in touch with someone who might. I would be happy pay a reasonable amount for somebody's time and expertise, and of course the components. Alternatively I am could trade some wakeboarding or waterski lessons for it! If just the components could be put together to make a functioning circuit, I can get the whole thing put into a suitable box. If it can be built successfully, I will actually need two. I have been told that it should not be difficult but it is certainly beyond my capabilities. I am in the UK. The device needs to have a countdown timer, with a display for the driver to see. It needs to trigger an audio and visual warning when getting close to a fifteen minute time limit and, when the time is up, to reset itself. It also needs to switch a fairly bright light which which will reflect these actions and can be seen from behind the boat . It was suggested that this could be based on an ARDUINO board. It would draw its power from the boat's 12v system. The sequence would be as follows: Timer is started by driver The digital timer display starts to countdown from 15 mins in seconds The boat driver will see from the display that the timer is running. A light bright enough to be visible to a person 20m behind the boat is illuminated so he/she also knows the timer is running. At 12 minutes, the driver gets a visual warning, maybe the display flashes, perhaps once per second. The person behind the boat also gets same warning on their light. i.e. flashing once per second. At 13 minutes 30 secs, the display flashes more rapidly and a buzzer also sounds for 10 secs. indicating to the driver that the time is almost up. The person behind the boat also gets the same warning on his light (i.e. rapid flashing) (may want to incorporate an audible warning too, loud enough for them to hear). At zero, the timer automatically resets itself to 15 minutes and restarts.  At this point the driver has the option to allow it to continue running without interruption for the next 15 minute period and so on, or he can stop the timer manually, when it will simply reset to 15 minutes and become idle until started again. N.B. A facility which allows the timings to be customized would be very useful (presumably this could be done by changing the Arduino code?) So thats it. Simples! (apparently) If you think you can help me with this and I will be delighted to hear from you. Many thanks Mike mirlyn

wind up timer device

Hi all can someone help me find out a way to make a wind up timer? - all it needs to do is manually wind up by hand, unwind through a series of gears slowly.....but needs to have a strength of about 2kg/cm torque. something to unwind for about 30 minutes would be perfect is there anything out there which can be used..or a simple way to make using spur gears and a coil spring? many thanks

Arduino code help

To the Instructables members,       I'm trying to write a program that uses a pushbutton (momentary) to turn on and off LEDs.  I have two LEDs and one button.  Basically, I want to be able to push the button to switch LEDs.  One push - one LED turns on - another push - the second LED turns on - another push - the first LED turns on - and so on.  Anyone know how to do that?  I'm sure there's a simple solution that I've missed.  Any aid would be awesome.

Arduino + Timing Device used in Profession Rugby

Hi, Patrick here. I am building a scrum sled training device and hope to use an Arduino MEGA to do the thinking! Basically the idea is simple enough. I want the Processor to start a timing sequence once a start button is pushed. I want the processor to then activate a voice saying, 'Touch, Pause....Engage' Much like you hear the ref saying in professtional rugby. Once the word 'engage is said by the processor through a speaker or buzzer, a timing sequence would start, and ending when the player makes contact with the pads on the scrum sled. This conact will bge made by limit switches feediong back into the processor ending the sequence. I have attached a PDF of the sled design. Can Anyone help me with the programming!? ANY HELP at all, is very much appreciated. Thanks again, Patrick

Timing chain cover

I have a 97 dodge dakota and I need a new timing chain cover. On-line purchases are out of the question because I'm short on time and cash. I will be going to pick n pull to get a replacement but they currently only have years 91, 92, 93, 95, and 99. My question is this, how do i find out how similar any of these other covers are, short of driving all the way to the yard and inspecting each one. does anyone know off hand how interchangeable this piece is?

Negative posting times again in Q+A, and shifting post times

When sorted by recent, the top couple of posts in the Questions section have started showing negative post times again (and not chancing to hours after 60 minutes). As of 6PM UK time, the top two questions are showing information like this: "Asked in Technology by miamimac  -293 minutes ago    Answers: 1" This problem has appeared a couple of times before, all while running chrome on win7, and the issue persists after refreshing the page. EDIT: after looking for a bit longer, new questions are getting added to the list after the ones with a negative posting time. ADDITIONAL: recently, post times have been jumping around, causing posts to be re-ordered and Questions posted recently (with correct posting times) to be moved up, often ending up with negative posting times. Are all users seeing the same posting times, or are the faults dependent on area?

Time for a free boat!

Times are tough. People don't have the money that they used to. Some of those people own boats.According to the New York Times, boat-owning Americans are abandoning their boats in droves by sanding off the names and serial numbers and setting them afloat.Do you know what this means? It's ripe time to get yourself a free boat like Tim Anderson did some years ago in much more prosperous time.

timed detonator

Ok, I LOVE airsoft, as many do. I wanted to make a time bomb detonator for different missions, where we could set the time and your squad would have to get there and disarm it. All it would do if we didn't make it in time is set off a smoke bomb. That way everyone would know the game was over. but I do not know where to get a battery powered alarm clock. (the dollar store doesn't sell them) does anyone know where to get one?

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.

New Years 08: How We Could Theoretically "Discover" Time Travel/ers

Well that forum on time travel got me thinking...How We Could "Discover" Time TravelWrite down, carve on stone, burn into our memory, tatoo on my back, or something, that if/when time travel comes into exsistence, someone needs to travel back in time to a specific time and date in our near future (Instructables Control Tower, New Years 2008 would be a good time/place). If everyone were to record this, eventually someone/s might do so, meaning that a time traveler might turn up at Instructables HQ on New Year's. I personally intend to attempt to do so, or at least get my future kids to:)Anyways, if a good number of people do exactly this, there might be quite a congregation at Instructables on New Year's. Or of course, no one might turn up at all...

How discover time travel... i think

Long story short, my friend found some instructions of how to create a time machine or something. The drawing looked kind of dirty so instead of keeping the drawing, she just took a photo of it. She showed me the photo, which turned out to be real blurry and crappy.I posted the blurry photo up on this site, and someone commented that the original image is on a site called asiko.org It's some weird $h!t. I emailed them but never received any word back as to who is behind this. But anyway I figured to post the instructions here because it does seem feasible. The plan is basically this:1. Choose a date, time and city. These 3 things are called Asiko. Let's use 01/01/09, Time Square NY, New York just for clarification purposes.2. Popularize Asiko till step 53. Meet at Time Square on 01/01/09, and we should see a time traveler from the future4. In the unknown future, a time machine will need to be invented. Still popularize Asiko, 5. When they figure out how to have "safe time travel", a traveler will be sent back to the popularized location and time of Asiko, which is Time Square, 01/01/09.
