Flip flop?

Hi, I'm a little rusty in digital electronics, does the attached diagram represent a flip flop? I need a logical circuit that change state (output: from 0 to 1 and vise versa) when triggered (pulse). An I.C. number would be more helpful. Thanks!

Flipping bucket help

Hi all , I need some help with an Instructable . I have a very slow stream of water near my house I want to use for irrigating my garden (~10liters / hour) and I want it to fill a container (bucket) and flip over to another container when it gets filled . The bottom bucket will connect to my droping irrigation hose. If I connect it directly only some plants get water all the time . I need it to build up and then water them all periodically . I hope I explained myself well . they have this kind of mechanism in water parks .. How do I design the flipping bucket ? where do i put the hinges ? Thanks.

Adding Mic Input to a Flip Mino Camera?

I was looking to add a microphone input to my lilliputian Flip MinoHD. My current thinking is that I could just take the leads from the current, built-in, mic and run them to a two-position switch. From there I could then have a 1/8" input on one side of the switch and the original mic on the other. Then it would all be a matter of dremeling out a small spot for the input and the switch on the side of the body so that I could select which input to use.First of all, I'd like to know if that would even work. I've done electronics work before, but have never worked with mics, so for all I know I might just walking down the pathway to a voided warranty and a bricked Flip.Secondly, I was wondering whether there might be a method of bypassing the need for a switch, so that if there was no mic present the camera would use the built-in mic, and if there was, it would use the input.Any help would be greatly appreciated. I was a big follower of the original CVS camcorder hacking movement, and I'd love to see the Flip get the same sort of treatment.Thanks.-NickPS: Does anyone have any pictures of the internals of the Flip MinoHD? I've been looking around but can't seem to find anyone who's dissected theirs.

Pimp my flip clock!

Hello dear Instructables community, I need your help:I have 2 flip clock, The 1st one is a regular flip clock, just for time that works with 2 AA batteries, there's 2 lever or switch at the back that allow me to adjust the time. The 2nd clock works with 1 AA battery.... the battery is only for the analog clock, it doesn't change the date or day of the week, I have to do it manually (there's a button for each).I would like to link them together: when the time turns midnight, I want the other clock to change date and day of the week. Both clock would be in the same frame (I know how to do that). I'm sure I can do it, but I need to know what pieces I need to use so they can work together, I need your help dear community!Thanks a lot in advance,Nick

Timer to flip light switch?

I need a timer that will mechanically operate a wall switch for a light. I've seen a device years ago for sale in the various "gadget" catalogs that did exactly this. It attached to the trim plate around the light switch using the 2 trim plate screws. A battery powered digital timer operated a mechanical slide to operate the wall switch. I can't find this device anywhere now. I know there are many electronic timers that replace the wall switch and have timer capability, most do not work with compact flourescent lights. I'd really like to find a timer for sale or get some ideas on a simple way to make such a device. Thanks for any help. Scott

D-Flip Flop and Clock Alarm

Hey there! I'm trying to hook up one Set Pin of a 74LS74 Double D-Flip Flop to the alarm of my clock. I've already desoldered the annoying buzzer thats been there before and am now measuring the voltage provided to the buzzer. Unfortunately the circuit only provides around 0.1-0.7V (crescendo alert) with each beep, which doesn't seem to be enough to raise the Set Pin to HIGH (0.8V min. I think). So I guess I'm supposed to use some kind of transistor now. Just to make sure I'm asking you guys. Also, if I want to run the clock from a 5V DC wall wart instead of the original 1.5V battery, I suppose the only thing I need to add are some resistors in series. Would that be correct or would there be anything else needed to ensure the clock takes no damage? Would be really nice if someone could help me out with this! Best regards, Philipp

I want the x's to blink on when the 0's are off and the O's on when the x's are off. or the first xo then the 2nd xo. not sure yet. also want the "tempo" i.e. the resistor value to be changeable so i can make it faster/ slower thank you!

Can anyone teach me how to make a remote control plate flipper for my license/vehicle registration plate for a car show?

I have a car contest coming up in Indonesia and we have a choice to remove our plates to protect our identities on the streets from show visitors. It usually takes a small amount of effort to remove the plate screws and fix on the contest user name but I thought it would be nice to have it automatically change when I enter the show (might help me gain more points :D) I have tried to search for this item online but some only supply the item to Russia and the rest of the sellers are in China. They cost around 290 dollars for a set, which I thought was quite pricy. To be quite honest in that 290 dollars I was going to spend, I doubted that the China factory would use the best quality materials considering the price. So I was wondering if anyone could help me make one of these automatic revolving plate frames with remote control operation for the auto show? It would be really great as it would help me gain more points! These are the links of the Russian company and Chinese company that produces it: 1. http://www.plate-flipper.com/       They have videos (Russia) 2. http://www.aliexpress.com/store/product/AUTOMATIC-Automatic-Flip-license-plate-revolving-license-plate-frame-free-shipping/101548_517916045.html               They don't have videos (China) Thank you all for you help!!!

Using Capacitors in a flip flop LED flasher circut?

Hello guys, I am very new to electronics, so please bear with me. I am trying to build using specs from various places a seemingly simple flip-flop led flasher using a 9V dc power source, a pair of NPN transistors, a pair of capacitors, a resistors. Now I have built the circut several times on my breadboard. I have yet to get the circut to work. I tried to troubleshoot the problem myself, and done a little research. It seems that capacitors wont work with a dc current, or so most of the web sites say. The problem is all of the circuts I have seen use capacitors, even the 555 circuits. The only thing I have done different from the diagrams is I am using a slightly larger (30 or so farads) cap. They are the the ceramic disc type. Am I using the wrong caps? Not sure what I am doing wrong?

How to make Flip Clock Numbers and build a "like"-counter around it?

Hey All So I've got this client, who's absolutely crazy about the "FLIKE" (A physical like counter.). But he can't have it for another couple of months, and he'd like it to be a little more custom... Long story short, I might end up making a similar product in a few weeks. it will probably consist out of 5 digits and if it's up to me (not sure what the client wants) I'd stuff them behind a long picture frame. Something like this but actually mechanical and not just a picture of it:  http://www.notonthehighstreet.com/thedriftingbear/product/personalised-framed-vintage-flip-clock-print So I started googling every hardware piece I needed and it turns out it's a huge pain to find Flip Clock Numbers / Flip Board Numbers... whatever you want to call them. (What's the right name btw?) You can't just buy these things, let alone in a custom size. So the idea is to build them myself. I found this on wikipedia, which gives a clue about the inside: http://en.wikipedia.org/wiki/File:Analog_clock_with_digital_display.png So I'm figuring out what needs to go in it to make this work. (I'll end up making an instructable about it) The numbers themselves are going to be made out of vinyl stickers. You can easily buy those from ebay in about any size if you look for them. The stickers will be put on to plastic boards. But I'm not totally sure what kind I should get. They should be thin and must be able to stand up straight, yet "easy" to fold. I'll probably get them lasercut, but you should be able to cut them by hand as well. Currently I'm thinking about gluing small metal or carbon rods on the back of those letters. Although I'm not sure if that would be strong enough. Would it be enough to file one side of the rods to get a bigger contact surface? (What do you guys think?) I'm planning of putting the half letters in a drum of ABS or PLA. it should be shaped like this:  |--------| I'm thinking about 3D printing this. But no idea how it'll do... One side of the drum will be connected to a small stepper motor (5.625° with 1/64 reduction). I don't have real experience with stepper motors, but this resolution seems more than sufficient. The other side will be connected to a metal or plastic positioner. Each digit might end up with it's own "unit" so I can swap them separately if they'd break. I've got great experience with lasercut plexi, so I might use that because it's more accurate than wood and I might have some lying around. I was first thinking about 1 stepper motor and a set of gears. I decided not to do that in the end because I don't have good experience with making gears and I can never find the right sizes online. Also, it'll make everything way more complex. So each motor will have it's own controller connected to it. Those controllers would have to talk to an ATMega or something. (I'm planning on using an arduino to prototype, but then just swap the chip and make a stand-alone version without usb etc) The ATMega has to be connected to the internet of course to get the current number of likes, so I'd connect it to a raspberry pi via I²C. I'm not familiar with the GPIO pins on the pi so I figured this would be a save and convenient way to handle this. The ATMega is robust, and I love the Arduino bootloader. A sketch is written in no time, but I have no idea how to start writhing this code for the GPIO pins. So why the Raspberry Pi? First off, this thing might end up being wireless, and since a wifi module for the arduino costs as much as a Pi, I figured this would be easier. The plan is to make the pi run python script that could ask the number of likes from the facebook API. Once returned, it'll send +1 or +5 or +10 over I²C. The arduino shifts the numbers to the correct position and replies with the total number it's displaying (3012 for instance). The PI can then recheck if everything is in sync. As for the set up. Since we have Pi, we can put on a LAMP stack (I know, this is overkill, but it wouldn't hurt either). So for initial set-up, we'd connect the counter to ethernet, browse to it on a different computer via "http://counter.local". And we'd be presented with a web interface. You'll be able to set the URL of the page u want to get the likes from, set and reset the number that is displayed on the counter, and the WIFI settings. The WIFI settings can be saved in the wpa_supplicant.conf file and on reboot it'll automatically connect to this network. From now on the whole system is manageable over wifi via a html interface. For debugging I might enable ssh though. So I guess you've got the whole outline now. I'd like to get your feedback on this! And this for the mechanics, electronics, and software side of things!

I have a question about using a 555 timer as a flip-flop? Answered

I have it set up so that I get an out put signal that goes High for about 1/2 second, and then goes low for about 1.33 seconds. The problem is that the output is to go through 2 LEDs, the one is supposed to light when the signal goes high, and the other when it is low, since I have the other leg of each LED tied to ground or source respectively. IF you are really familiar with how LED's work, you probably see the problem I have already. When the signal goes high for the first time, the LED tied to ground, lights....and stays lit. The source provides current whether there is a signal out or not. Is there ANY way around this, without me having to scrap this and redesign it for a 556 ? NOTE: I've replaced the stock pic with a partial schematic of my circuit

So, first round of suggestions will be how to fix this. Note: Windows OS has built in capabilities to do screen ROTATIONS but not FLIP/MIRROR. I cannot stress enough how many people assume rotating, flipping, and mirroring are the same thing. In Microsoft's built in display panel they list: Landscape, Portrait, Landscape(Flipped), Portrait(Flipped). However the two flipped settings are merely rotations.
