I want to thank everyone for the truly massive response to my robot arm. I have decided to launch a Kickstarter for this arm to fill a need that exsits for a low cost robot arm that anyone can program and help to automate the workplace. https://www.kickstarter.com/projects/152911884/six-axis-robotic-arm

I am in a long-distance relationship, and our six month anniversary is coming up. Does anyone have any gift suggestions? I am getting her a webcam, because she doesn't have one and we will be able to see each other. Also, I just recently sent her a bracelet (a souvenir from my vacation). So any other ideas that are preferably not jewelry and hopefully quite inexpensive are welcome.

I'm 16, and me and my boyfriend have been going out for six months soon. I want to make him something for Christmas. He said he wants something that reminds him of me. I can make most anything if I try, 'cept for shop/wood things. I also have this little puzzle box and in it you can fit something up to the size of like a 50 cent piece. I want to maybe hide something in here as well- anyone got any ideas?

Thought these might make good tool organizers, mesh bags, or any potential items that would be practical, useful, and eco-friendly. Discarding these without clipping the rings has had a negative impact on wildlife by entangling them, so thought would try to put them to good use and save money. There are likely many gardening, art and craft applications for these also.

I am currently working on a school project that involves building a vehicle (Must move forward, backward, left and right. Two DC motors are used for this), having a robotic arm placed on the vehicle (Six servos will be used here), and all controlled by a DualShock 3 Sixaxis Remote. My plan/idea is to use a Raspberry Pi for this. I have only a small amount of knowledge on working with PWM (I do however know what it is), Raspberry Pi programming (All i have used it for was wifi/network related, not to actually control something), and most of what i am about to ask. My question, is can a Pi control six servos, along with two motors? I have seen this, which is suppose to be able to drive up to sixteen servos. I have also seen an Instructable on driving a vehicle remotely. Also, there are guides on connecting DualShock Controllers to Pi's. My question, is it possible to combine the above three? What hardware would i need (I need to build my shopping list fast, and it needs to be on the cheaper end, as the servos, arm, and vehicle wasn't very cheap.)? I already have the two motors for the car, along with the vehicle itself. I need help finding servos (I have never really worked with them to the extent of shopping for them. They need to have decent torque, decent speed, and most importantly, be able to turn 180 degrees), I have the Pi, with a Bluetooth Dongle (And the controller). What else would i need? I did see the IC in the 'able, and i assume i will have to get that as well, along with the 16 channel PWM driver? Will it work? Do any of the Pins overlap to such a point where it is not possible/are conflicting? Currently, i would need a yes/no answer, along with a parts list. Programming comes a wee bit later, but i will also need help with that.

Historians traditionally tell us that to ignore history is to repeat its pitfalls. So how can history help us improve the flow of car traffic? Did you know that many aspects of the world’s legal systems come from biblical origins using tried and true fundamental laws originating from the Ten Commandments? The concept of “watching your six” borrows from these universally accepted laws, whose credo stipulates guidelines for human interaction as well as interaction with god. Your "six" refers to the driver behind you whom you should treat as you would yourself. With this in mind, we have a new credo for today’s need to interact with each other by driving your car responsibly through high density traffic to avoid “wave congestion". This term is used to describe isolated packs of cars suddenly causing a local slow-down in traffic flow, while both upstream and downstream traffic continues to still move well, and so our rule states: “Drivers are responsible for the immediate driver behind them, keeping him safe and avoiding unnecessary braking” How This Rule Works In traffic: 1) The Rule is Expansive, All Inclusive and Saves Us Money If we followed this general rule, we would become responsible for leaving the proper space/time ahead of the car in front of us. Space clearly gives us reasonable reaction time to perhaps "brake by simply coasting" and not force the driver behind us to suddenly brake hard. It will help us to recognize that the proper spacing between cars is not an open invitation to dart between lanes just to get ahead by one car length. This causes “wave congestion” and the possibility of accidents during heavy traffic situations. It assures that braking is something one does as a "last resort" and only when no other circumstance for safety and/or avoiding a collision is available. It holds the “rubber-necker” responsible for maintaining good traffic flow or get ticketed. The rule encourages a driver to adapt the techniques of defensive driving so as to avoid accidents, and to embrace the proper social skills of driver etiquette to mitigate road rage and its associated erratic driving behavior. Ultimately, the rule will financially help us to reduce our car insurance costs by promoting fewer negligence accidents. 2) Eliminate Reactive Braking … Trust the Driver In Front of You Keep in mind what normally happens in heavy traffic when the first driver uses their brakes either in idle thoughtlessness or in protective response to traffic congestion ahead. Under these circumstances, we reactively use our brakes for two reasons: a) Reduced Reaction Time - The first car’s brake lights go on, giving us less time to react so we over compensate by braking harder than him. This affect gets compounded, causing each subsequent upstream driver to brake still harder, until the reactive braking time becomes impossible to respond to and a collision or multiple collisions occur. b) We Don’t Trust Other Drivers - We are conditioned not to trust our fellow drivers because they haven’t yet been educated to abide by our Rule. This lack of trust causes us to drive "overly" cautious and results in the over use of our brakes to defend ourselves. Our driving habits have created a psychological situation just waiting for an accident. 3) Implies Driving Etiquette that Must Become Required Driver’s Education The rule and its derivatives must be taught as part of our driver’s education program, and their concepts definitely reviewed during the licensing exam. The Rule also includes adherence to a driver’s code of etiquette which goes beyond just obeying our basic traffic laws of vehicle safety as is currently done. Highways are becoming too congested to allow rouge drivers to ignore their “social” driving responsibilities and the etiquette of the road. Traffic tickets for abusing social driving etiquette should be as prolific and costly as our traffic laws for speeding and/or not stopping at a stop sign, etc. 4) Compliments Our Near Term Use of Self-Controlled Vehicles Our Rule intrinsically implies the responsibility for social driving etiquette and takes us forward with steps that avoid future traffic congestion. Improvements will come from technological automation which will eventually take the erratic human factor out of our equation to produce the smooth flow of traffic even during congested periods. Something as simple as today’s cruise control helps us to avoid “wave congestion” by maintaining a constant highway speed plus reducing inadvertent “brake riding” which sends the wrong message to the driver behind us. Our ultimate step towards smooth traffic flow involves using near-term technology that completely eliminates drivers and relies on self-controlled vehicles taking over within regions of high density traffic. Ideally this will eliminate traffic accidents due to the unpredictability of driver shortcomings, making technological glitches our only possible area of concern in the near future. Google, in cooperation with the state of California, is currently in the process of introducing such vehicles onto the state’s roadways.

It's been a while since I've made a forum topic, but here it is: an overview of what I've been doing lately. First order of business, I've built a pistol with a sliding trigger. It works very well: the sliding trigger has never failed, and it gets pretty good ranges for a single shot. The only problem: I am using terrible bands, which I'm sure is limiting the power, unfortunately. Some of its features: It has a bullet lock. It gets great ranges. It has a sliding trigger. It has a comfortable handle. It isn't a turret pistol :P For the second order of business, I have built TheRacker's Racker Rifle with the new trigger shown here. I modified it a little, but a lot of things remain unchanged. I have decided to review it. I. Design Elements Trigger: 10/10: The best element of the gun. It functions flawlessly and was my main reason for building it in the first place. Barrel: 8/10: The main part of the barrel was fine, but the place where the turret was supposed to catch on was a bit iffy, as the y-rod that it was supposed to catch on could fall off easily and turn a little bit. Stock: 7/10: It was a bit flimsy, but it was aesthetically pleasing in terms of piece usage. Pin guide: 3/10: Here's the worst part about it. I know I don't have the original pin guide in the picture, but there's a good reason for that: after one #64 size rubber band, the pin guide simply would not work. It bent and moved and wasn't secured to the barrel in any way, causing quite a problem. I took it off and modified the barrel, but when the picture was taken, I was experimenting with an alternate pin guide. Handle: 8/10 The original handle was a bit simplistic, but seems, from appearance, to be very comfortable. I modified mine quite a bit. Turret: 0/0: As it isn't TheRacker's design, and it is the basis for all turret guns, it's pointless to rate it. II. Functional Elements: Aesthetics: 10/10: It is a very aesthetically pleasing rifle, and there's not much more you can ask for. Innovation: 9/10: The trigger is new and that's much more innovative than a lot of other guns that have been posted. Piece Consumption: 10/10: TheRacker Rifle was built with piece consumption in mind. It is definitely worth a build if you don't have a lot of pieces, but you want a nice rifle. Power: 9/10: For a pin rifle, it was quite powerful. It can always be better, though. Durability: 7/10: Everything is very sturdy, except for the stock. If dropped on the ground, not many things would break. Overall rating: 81/100 = (Approximately) **** / ***** (Four out of five stars.) -DarkOwlKnex , , (O,O) <(IIIII)> I I

Does anyone know where to buy good lengths of 6mm ID stainless steel or brass tubing? When I say good length I mean like around 4 feet continuous. And the tolerance must be very good, in the degree of 0.01mm I've been searching for a while, but getting metric tubing in the US in lengths of anything more than 10 inches or 300cm is hard. The closest I've found was 6.22mm (which is really 0.2425 inch or something like that), but Ideally I want the ID to be between 6.00 and 6.08 mm and in case if anyone is wondering, I'm building an airsoft sniper, which uses 6mm BB's

Firstly, I am sorry for my lack of knowledge on the subject of electronics. I have an output voltage of 6 DC volts that I would like to amplify to run 8 LEDs in series. What I am trying to do is use this colour organ to run more than just four LEDs per range of music. I need it to run eight. I was wondering if there is any way to do so, that would be relatively simple. Would buying this work? I don't mind buying anything extra in order to do this, so please, help!

I'm a first time auto insurance buyer. Let me pose this question in an interesting manner: You're an insurance agent. You just quoted me at $500 every six months for bare-bones/state minimum coverage (just for example's sake). Do you ask me for $500 upfront, then $500 six months later? Or do you issue me an insurance card and expect the first lump sum of $500 six months from now?

I've been trying for around 3 months now to start a solid exercise regimen, but so far my efforts have been fruitless. I'm a junior in high school who runs cross-country and track, but I have decided not to do track this year. I can run a 21 minute 5k, so stamina isn't really an issue. But to be frank, I would really like to build some muscular definition. I have all the necessary equipment, (treadmill, weight machine) but I'm unable to start and maintain a consistent schedule. At most I may exercise for a week or two at a time, and then relax for a week. My main issue is a lack of results, which leads to a lack of motivation. TLDR; I WANT SEXY BOD NAO PLZZZZZ!!!1!

Eepybird, the "Coke and Mentos Guys" used 108 2L bottles of Coke Zero and 648 Mentos to propel a car/bike 221 feet! An explanation of how it works, from their YouTube video: "The Coke Zero & Mentos Rocket Car uses a piston mechanism: a six-foot long rod sits inside a six-foot long tube attached to each bottle of Coke Zero. When the Mentos drop into the soda, the pressure tries to push the rod out of the tube. With 108 rods all pushing at once, that gives us a lot of power. All that power is pushing against a wall braced with 3,600 pounds of cement blocks. So all the force is directed into moving the Coke Zero & Mentos Rocket Car forward. We get one big push for six feet, and then it's all coasting from there." via msnbc

So why isn't it here yet? I asked once already about this delay, on forum i think, and they told me that it's because there are many prizes that are holding the sending back.
