simple logic circuit

Uuhhh..I'm not really sure about this..i'm an electronics engineering studentand my instructor in Logic Circuit and Switching Theory requires us to make a project which will include logic gates.now i searched in the net for some ideas i found two..but i know i shouldn't copy their projects..can anyone help me?link2link1thanks guys!

Logic breaks reality

My friend told me about this earlier today and I thought it was brilliant: Cheese has lots of holes. The more holes you have, the less cheese you have. The more cheese you have, the more holes you have. So logically, the more cheese you have, the less cheese you have. This got me thinking and I'd quite like to see if anybody has anything similar to this logic fail.

Logic gate help

I'm attempting to build an binary calculator out of an old iphone box using LED's and such and have a wiring system set up but i need to know how to make/buy some form of "if then else" gate (i.e. if A=1 then B=1 else C=1 and if A=0 then B=0 and C=1). I would love to know if there is some kind of way to do this using transistor logic but anything that works as an "if then else" gate is welcome.

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...

Solve this logic puzzle if u can!

Here the puzzle:[img]http://img247.imageshack.us/img247/6384/newyearpuzzlecj7.gif[/img]Questions: Imagine that you have the layouts of 4 coloured cubes(ABOVE), named A, B, C and D. When the cubes are placed in (alphabetical) order in a straight line, and it is viewed from any horizontal or vertical position (front, back, top, bottom, left, right), there are always four different colours seen.Given that when I pick a corner of A, the 3 sides connected to it read "653", find the same orientation of B, C and D as 1 string of numbers. For example, "152421563".

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.

Step selector displays wrong info

When you view any published instructable with multiple steps the step selector beside the PDF download button displays wrong info and behaves abnormal. This image shows I am currently on an intro page, yet the button is displaying step 2, which skips over step 1. Also clicking this button does not redirect you to the step. You actually have to double click it to get it to transfer you to the next step which would be step 2 instead of step 1 because of the bug. http://i.imgur.com/Ib9Q4PA.png This image shows me forcibly to step one and hovering over the arrow. It does in fact display the correct next page, and transfers you when you single click like it should. http://i.imgur.com/MsVN4Jk.png This image shows that everything is working like it should after the intro page. http://i.imgur.com/56HGgGm.png Overall this bug is simply a graphic/logic error bug on the intro page of all instructables which forwards you to step 2 instead of step 1 of the instructable. The standard next/previous buttons at the bottom of the page are not effected.

New slingshot mech/trigger

I want to keep this brief whilst still remaining informitive, please excuse hurried typing hey guys been playing around with knex and found a mech that works. camera cable still lost, paint diagram below instead. to load band is attached to anchor at front, rod it then push/pulled through mech till trigger clickes into place, pulled further and rod is removed, ammo carefully placed back into mech (hollow back) trigger can then be pulled to fire. resultant gun is basicly silent, only one band can be used at a time. plans for a repeating version are still sitting around in my head. sorry for brief explanation, was kinda busy seeya later

Hey guys. I just wanted to put a quick message out to all of you. I am leaving. To be honest I havn't been able to build anything major since the I bow, also my priorities have changed, it is getting to the buisiness end of the school year here so free time is at a premium. I also have my new guitar, facebook, youtube and modern warfare 2 all fighting for my attention. I will be leaving the site and knex for the forseeable future effective immediately (not like mota boi and KGB who just hung around) My facebook is private so don't try to find it. If you must contact me, send a message on youtube. If you want to get your ass handed to you on MW2 my psn is tehlogicboy. Well thats all for now. goodbye.

the new shotgun on the block -EDIT-

-EDIT- Ok guys I sorry about not getting the pictures up but I do have an explanation. the picture shown was taken with my father's camera as I still cannot find the charging cable for mine. He "needs" his camera for work so I must wait indefinitely until I can "borrow" it to get some more pictures --------------------------------------------------------------------------------------------------------------------------------- Modern Warfare 2 confiscated? No computer or tv until 4 o'clock? what am I supposed to do? 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!!!

Cool Tool - Basic Stamp Logic Analyzer

A month or so ago Parallax had their basic stamp logic analyzer on sale for $30, so I picked it up. Its a slick little tool . It is handy to use when testing your wiring and software. If you have a BS2 and see it on sale again over at Parallax check it out. The only downside is the software is windows only, so mac geeks like myself will have to use a VM. -Joe

Attention! All other Logic Bows are now obsolete

Well I took apart my sniper because it had really bad range, and I though well what now. I built a Logic Bow The new version is shorter, cleaner and much better looking. It also is a heck of alot more powerful. The new design incorperates a pin guide that prevents the pin from lifting when fired (this was my biggest gripe with the original) It is better than any other version in every way. I will be posting this as a seperate instructable as basicly the entire gun has been redesigned. Unfortunately I cannot post any pictures until I have found the charging cable for my camera ='(. thats all for now.

A New Gun by Logic Boy?

Hey guys If you haven't noticedyou will see that I haven't made anything new since my PP19, everything that I have made has either been an improvement to something else or I never got around to finishing it. well my creative slump is over. I recently got some new knex and I now have built a new gun *gasp* it is actually the full completion of an older concept of mine that worked really well but wasn't exactly what I wanted originally. So I now have a pretty awsoime new gun. Pictures will be posted this weekend. Until then try to guess what it is. Hint: I have posted the name of the gun somewhere Good luck.

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.

UPDATE, I now have everyone needed to start the 'ible, for those who can't find it go to: you->instrucables->collaborations. UPDATE: I  have decided to start this abit early as I would like to have this out for christmas, failing that, new years. to all those participating, please remain impartial. Hey guys! I have had this idea for awhile now, what I want to do is a collaboration ible for a realistic knex war. I know jammy already did one, but I find his rules a bit unrealistic. What I want from you guys is anything related to a knex war, things like: -choosing weapons -rules (must be usable, like the KI ones) -different gametypes or even little topics like -Tr vs Rectangle Let me know if you are Interested. People so far Killer~SafeCracker - rules Dj Radio - Types of guns (only if he is impartial) logic boy (Me)- General tactics and the intro Silent Assasin21 - types of guns for different environments TheDunkis - sidearms Hiyadudez - assault weapons shadowninja31 - snipers and sniping jollex - just stuff knex gun builder - game types The Jamalam - game specific tatics If you want to ask me anything, feel free.

Help Me Feed My Dragons. Patches For Prizes.

I have three pet dragons. Their names are FRAZZLE, BURN and SPARKEY. One is ORANGE, one is WHITE and one is BROWN. They are fussy about what they eat and I need help finding food which will keep them all happy. How to play : Add to the thread by suggesting something they may like and I will tell you which dragons accept it.  From the responses, work out why each dragon likes what it does.  They appear to like a lot of vegetarian food, but I've a suspicion they may be cannabalistic too.  I also need to know the colours of the three dragons, and a list of 20 foods they will all eat. Grengate has deviously deduced the Dragons' colours.  Neuropol has cunningly calculated that Burn likes things with an even number of letters. Iceng has fiendishly found that Frazzle likes things with exactly two vowels in the name. Twinmum has ably ascertained that Sparkey likes things where the initial letter is alphabetically before the final letter of the word. Iceng has also provided a veritable plethora of foodstuffs which will please all the dragons. I now have three very happy and fat dragons. Winners' patches have been sent.  Thank you all for playing.

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.

Performance.

We all want our guns to shoot far and to fire fast, but how much performance do we actually need? Makers of Oodammo pistols boast that they shoot 60 - 70 feet, but there is no way that you can reliably hit a moving target with a knex gun at that range with any weapon, especially pistols. A good weapon should be able to fire fast, and be accurate to say 30 feet. This would allow the said gun to hit targets ar range reliably. Think about it.

PP19 Bizon

Hey guys, heres my early Xmas present to you, A PP19 Bizon, I decided to give it a go because I noticed that there hasn't been one posted, I wanted to give you guys a Xmas gift and I was bored, It shoots blue rods, havn't tested the range, but I'm expecting about 10m, nothing to special. I only spent a few hours on this so it may not be as good as I can get it. so tell me what do you think?

The GOP25

I was bored again so I made a modded version of my Oodammo pistol, now it has 17 extra shots, making it the highest capacity oodammo pistol that I know of. picture 1 is the gun against my computer screen (yay instructables!) picture 2 is a comparison with the original and picture 3 is a better veiw of the gun, I have also included the video of the original gun (it works the same but with 17 more bullets) Oh in case you were wondering the name stands for Generic Oodammo Pistol with the number of shots after it

tiq probe - a new kind of electronic debug tool for makers, techs and engineers

Hi! I'm launching a new product on Kickstarter this week that I think will be a great help to makers! It's called tiq and it's a new kind of high-performance tool for debugging electronic circuits, including projects using Arduino, Raspberry Pi, PCI, AVR etc. When you're debugging a project, you're usually looking for unexpected behavior, and you probe around the board to find out what's going on. With conventional test equipment this can require multiple pieces of equipment, hooking each up to your target, which often is in a hard to access place, changing ranges and looking away at the equipment displays. With tiq you can simply probe your circuit and tiq will display detailed logic level, logic pulse and voltage information completely automatically, without range switching or adjustments - and show it all close to the probe tip! Here's a one minute video of tiq in action: http://youtu.be/aNhjCvGdqkA Here's a short overview of tiq's features: http://www.innavatus.com Please let me know if you have any questions about tiq. I will post a link here to the Kickstarter page when it goes live. Cheers - Mark

Mechanical Logic Gates, got some of your own design?

ADHD version at the bottom =========================================== I've been fascinated by logic gates and how they're used for quite a while now, and then I thought, "why not mechanical logic gates?". After a few brief searches on trusty ol' Google, there aren't exactly "a lot" of sources from which to draw from. I've designed a few (rudimentary) mechanical logic components myself, such as an AND gate and an OR gate (I was gonna do a negated IMPLIES gate, but I came up with the idea during Biology class, so that's pretty much gone now). The thing with electronic logic gates is that they are standardized (kinda), which makes building logic circuits easy, because you wouldn't have to build hundreds of different designs of the same logic gate just for that circuit, alone. Maybe some of you have some logic gate designs to share? Maybe we could standardize some mechanical logic gates and someone might just make a cardboard computer out of 'em :D Just to add, I am aware of the usage of weights, balls, gears, linkages, and lever-type systems for mechanical logic. We can come up with a few for each type, I guess. (this excludes fluidics, the use of water and/or air for logical computation) Yes, I have searched instructables, but even then, not a lot of sources (though some are quite fantastic, might I add). ============================================= ADHD version: Got some ideas for mechanical logic gates? Maybe we can standardize them, somehow :D

Bolt Action Mech for a Knex Bullpup Gun.

This is an idea that I have had for a while now, it allows a bullpip gun to have a full black rod pin but with a more realistic design. the idea is using a shotened bolt that moves right back then pushes the ammo into the chamber. I'll see if I can get a pic up of what I mean

Why you can never have a "true" knex semi auto with decent power/range.

Ok here goes I will try to simplify my theory down a bit so everyone can understand: basicly energy cannot be created or destroyed, it can only be converted, eg kinetic into heat, chemical into kinetic ect. Knex guns are no exception, the enery has to come from somewhere, in most guns this takes the form of pulling back a pin or rubberbands to create potential energy, this is released when the trigger is pulled, this potential energy is converted into kinetc energy and this is how the bullet is fired. A semi automatic gun is required to fire every time the trigger is pulled, but the energy still has to come from somewhere. RBG's take this into account as each band is pulled back and has potential energy stored, however many knexer's opinions differ on whether this is truly semi automatic, many calling this type of gun a psuedo semi auto. Other guns use the energy imparted on pulling the trigger to create the potential energy to power the bullet, this is considered to be a true semi auto, however the main drawback of this system is that the amount of energy that can be transfered from the trigger to the bullet is very limited, therefore this type of mechinism has limited power. So if the problem is energy how do we solve this? one possible answer is to have an extra source of energy, such as a motor or a winding system that puts extra energy back into the system, however this approach will not give you a "true" semi auto as you will have to have an external source of energy, that and the fact that knex motors do not have the power and torque needed for this system. So what's your opinion, do you have anything to add?
