diode logic

I'm making a giant adding machine using only resistors(miscellaneous), switches SPST (for input) LEDs (for display) and diodes(for logic). NO TRANSISTORS I have it so that it can recognize 0,1,2,3,4,5,6,7,8,9, but if it recognizes 8, then it recognizes it as all the other numbers. If it recognizes 0, it recognize 1, and 7. If it recognizes 6 it recognizes 1, and 5. If it recognize 9 it also recognize 7. If it recognizes 3, it also recognizes 7. basically if you take a 7 segment display, any number on it, it'll recognize all the numbers in the number. I need help sorting it ou so that if it recognizes 8, it only recognizes 8. If it recognizes 3, it only recognizes 3. Etc...

Logic Problems

I changed the topic name because I think so people might think of logic problems as a programming question or electronic question, so some people wouldn't bother looking at the topic. Think you're good at logic? Here are some problems: Title: Gorillas Enjoy Ballet Gorillas are the only animal that enjoys ballet. All animals can fly to mars. Scotch brooms bloom every Thursday all over mars. Only those few animals that do not play solitaire are immune to hay fever. No animal that travels in leaky rowboat ever has the penultimate word in a verbal discourse. Scotch broom in bloom is what gives animals hay fever. Those that do not handle hot ice cubes travel to town in leaky rowboats. All animals that have the penultimate word in a verbal discourse play solitaire. No animal that enjoys ballet handles hot ice cubes. What conclusion can you draw from the above information? Logic Puzzle number 2 This one takes up 2 pages, so I'm going to skip the story and say the logic parts. Basically this one guy thinks he smarter than gods or something so they give him a trial. He's trying to go toward the treasure and not die. Split in the road number 1, at least one sign is false, one path leads to a serpent. Path A: "This path leads to the serpent." Path B: "The sign at path A is true." Which way should he go? Split in the road number 2, 2 signs are true, one is false Path A: "The sign at Path B is true" Path B: "Path A is not the one to follow" Path C: "This is the Path to follow" Which way should he go? Split in the road number 3, 2 signs are true, one is false Path A: "Path B is the one to follow: Path B: "Path C is the one to follow, unless it's Path A" Path C: "Neither Path A nor B is the correct Path" Which way should he go? There are now 3 houses, one containing the treasure, there's a sign infront of each house. 2 signs are false, but one is true. House A: "C is not the house to enter unless THIS house is not the one to enter" House B: "The sign at house A is false" House C: "Either house A or house B is the one to enter" Which house should he choose? Please write your answer in the form of the path/house in order, for example ABCB would be path 1 is A, Path 2 is B, etcetcetc. On a totally different note (I don't wanna make another topic), can you use the cable that you use with a boarduino to make an avr programmer? If so, can you post an example schematic of how to hook up a chip.

Relay Logic

I have a fetish for antiquated technology. Stuff like vacuum tubes, transistors, electro mechanical devices, and of course relays used to run things. I did a few searches here on Instructables on relay logic and found nothing so I thought I'd start a forum on it.  Most of the earliest computers ran using relays. I love how they sound, clickity - clack. In a way they seem more alive to me than todays silent electronics, and dead boxes, There's just something cool about a machine that you can hear working instead of dead silence, maybe I'm just a old fashioned.  Anyway, I have a limited knowledge using relays for adders, if, and, or, gates, etc. but I'd like to learn more. I did however make a clock circuit using only relays and capacitors, and I have a video of it here... http://www.youtube.com/watch?v=Ya5R7EqF8vk I based that circuit (after lots of pondering and experimentation) on the clock in this relay computer here. http://www.youtube.com/watch?v=n3wPBcmSb2U My relay clock was really unstable and would stop by itself quite a bit. I'd like to figure out how to make it more stable. Also, I'd like to do some more experiments... Anybody else have any interest in this subject? Or have any experience making small bit relay computers, or relay control systems for robots, etc? By the way here's some other cool relay run computers and stuff. Another Relay computer http://www.youtube.com/watch?v=O-omFP_G57U&feature;=related Relay counter thing. http://www.youtube.com/watch?v=YQ4ynGxQnGY Mechanical pong game - run on relays http://cyberniklas.de/pongmechanik/indexen.html

Logic Bow

FROM NOW ON I WILL NOT BE REPLYING TO QUESTIONS THAT HAVE ALREADY ANSWERED BY THE VIDEO OR THE WRITING BELOW, EXCEPT TO SAY "READ THE TOPIC AND WATCH THE VIDEO" UPDATE: The concept behind The Logic Bow (put simply so everyone can understand) By using a ratchet system to hold the bands behind the pin you can: @ Decrease pin friction in barrel @ Increase pullback distance @ Increase power @ Make the pin easier to pullback @ Have a simple rail system I have now uploaded a clip of the firing system in action for those of you who don't understand how it works UPDATE: HOW IT WORKS This is a pin type gun, not a slingshot. It uses a ratchet system to hold the rubber bands, therefore increasing the amount of bands that can be used and increasing ease of pullback. These bands are released when the trigger is pulled, propelling the pin into the bullet. This means that the effective pullback distance is increased, therefore increasing the range and power. well here is the first "new thing" I have done in ages, (the last Truly innovative thing I built was the D-Frag grenade) the Logic Bow. It uses an all new 4-stage firing system that runs between two rails (I tried using a dual rail system but that didn't work out). So far I have the mech working, but it needs the rest of the body, the bow, a handle and probably a stock. It is a single shot that should have more power than a pin gun, the really cool thing about it is that although it uses a pin mech the pin takes almost no effort to slide back. I will keep you updated as the project progresses, Feel free to ask any questions. Update: I finished the entire gun and uploaded a couple of pics (see below) This will soon be posted.

(Note about Internet safety.  There is an attack which is becoming more common, which can be embedded in PDFs using the Javascript capability in Adobe Reader.  I did a bit of research and I am confident that these Logic Goat PDFs don't contain any malicious code, but as with anything on the Internet, download at your own risk.  In general it is wise to disable Javascript in Adobe Reader, if you use that for PDF viewing.  There is an interesting discussion of one of these attacks here: http://isc.sans.org/diary.html?storyid=7867)

Logic circuit to generate and convert 3 bits parallel binary code into series for subsequent transmission ? Answered

A project I am working on has 6 water sensors placed at different altitudes inside a tank.I've developed a circuit to assign 3 bit binary codes to each of the sensor and then transmit it wirelessly.I've attached the truth table and the binary functions that yield the desired output, as a picture.Please refer to it and check if it looks alright to you.Keep in mind that the sensors output '0' (ground) when idle and '1' (Positive) when active.  Also, the sensors are so placed that sensor 2 won't get activated unless sensor 1 is activated ,sensor 3 unless sensor 2 is activated and so on..I.e,when the sixth (last) sensor is activated ,all the other sensors would be active too.So,the truth table contains just the possible combinations. A,B,C,D,E and F are the sensors(bottom to top) X,Y and Z will be fed into a binary encoder ic,whose output will be transmitted. Surfing the web,I realised that logical high and low can also be set using pull up and pull down resistors .I would appreciate it if someone could enlighten me on how this is done.(Explaining with reference to my circuit will be the best way)

Logic gate set up with basic principal of "A is I: B is I for 1 click, then O//A is O: B is I for 1 click, then O"?

I've been looking about for awhile now for a solution to this little puzzle I've managed to get myself into. I know the question may have failed to be a proper logical statement, but basically, this is what I need: When input a is on, output b will toggle on for one second, then toggle off. When input a then goes off, output b will then toggle on for one second, then off. Basically, when the input state changes, the output will go on for a second, then off. I know the opposite can be done (that is, one second input toggles a on output, or visa vers) with flip-flops, but doing this is a bit outside my realm. Any help would be fantastic! Thanks in advance!

Levelshifting 3->5V. Can I add a DC bias of 0.5v or so to the 5v input line to bring up the 3v signals?

Assuming it doesn't just line up correctly, eg: If my Vih is 3.6v on the 5v side, and my Voh is 3.3v on the 3v side. By DC bias I mean connecting up a voltage divider giving 0.5v to the line connecting the 3v->5v. I'm guessing this isn't done as it would drain power when the 3v line goes low, but if the divider is high enough resistance, that could be minimal?

NPN to PNP control? Answered

So as I get into this project the circuit keeps building and now I once again have another problem that I can't figure out. As the title hopefully suggests I am using a NPN PN2222A trans. to control a PNP 2N3906 The idea was to use the 5v from a Ardinuo UNO to control a 12v. Currently I am testing with a 9v I had on hand. I thought it would pretty straight forward but every time I supply power to the NPN it creates the short needed to turn on the LED, but once I cut the power the LED stays on until I create another short (using a probe) uphill of the NPN. The only thing I can think of is that the LED doesn't the resistance needed for the power to re-saturated the PNP. Any thoughts? I will admit  haven't done any of the math needed yet for the resistors. Also can someone send me a link to the programs you use for drawing the layouts so I can move past MSpaint?

Touch pad using tester logic? Answered

Hi everyone,                  I was planning to make a doorbell of which's switch is a touch pad.I tried understanding the logic behind the touch screens used in i phones and such otherd but they seem a bit complicated.Another solution I got was a circuit which has two free wires and when a person touches the two wires(creating contact),the load gets power.This is based on transistor switching.But I don't want to adopt this design since........ I don't know for some reason.Then I remembered those classy electrical testers(seen in the picture).They have a neon bulb in them which glows when they get a voltage of certain range from one end and our body is used as ground when the other end is touched.So if I use this mechanism I just have to use the setting to power the load when a metal plate connected to one end is touched by a 'user'and a voltage is given through the other end.I know these things usually have a neon bulb as they handle AC voltage.Finally here's what I actually need to know- Is it possible to build such a circuit where a 12 VDC is supplied to one end and the load is given power when the other end meets ground(here the person touching the pad).Maybe this might be a total jabberwocky but anyway contribute your valuable suggestions.If anyone has seen such circuits elsewhere, a schematic could be really helpful.Thank you in advance.

Search engine uses OR logic instead of AND

Hi, I'm a new member, but I've been browsing the site for some time. I think it contains lots and lots of great instructables, but it is annoyingly difficult to find something specific. The problem is the logic behind the search engine - why are you settling for an "OR" instead of "AND"? Here's an example: I want to build a raised dog feeder and I want to find some inspiration on Instructables. But try searching for phrase "dog feeder" and half of the results are bird feeders: https://www.instructables.com/howto/dog+feeder/ I really don't care about bird feeders (at least not at the moment). There are also dog toys, dog beds, dog apparel... So I need to browse through hundreds of Instructables in order to find 2 or 3 that I might be interested in. If I wanted to find all dog-related content, wouldn't I just search for "dog"? Adding "wooden" doesn't help - results featuring Lego and plastic containers pop up... Adding multiple words in search usually means a person want to narrow their search results, instead of widening it... Thank for taking this under consideration.

Well here's the result of about 3 hours of boredom. Its a single shot shotgun that fires shells, however these shells are a red rod long and hold 3 white rods, plus reloading takes less than 10 seconds with a bit of practice. Range isn't too impressive, roughly 5 metres for 3 white rods and up to about 10 for a yellow.  More pictures will be up once I have finished exams on Friday this week,  45º handles FTL!!!
