Hey guys, me again bugging ya's. I took some pictures today of some stuff I've put together and I want to know how I should wire it together to do something useful with it. Take a look at the pictures below, my questions are mostly in the yellow notes. I have another question though, I have this here 6v sealed lead acid battery and was wondering if it's possible to charge it using a current less than 6v?

I have played around with motors hooked up to batteries and thats about it. i know a few things about electronics but i am looking to do some projects that involve circuits. i dont know how to read it when it is in a drawing. it looks to confusing to attempt. all those lines crossing and all those symbols. i have a book called electronics for dummys but it doesnt give to much detail. does anyone know how to read this stuff and can help me? is there any sights on the internet that would help me. remember i am pretty newbish. so it needs to be in newbish form. lol. the drawing below is from a powersupply that i would like to build. thanks ~Josh

Okay so this is where you would go to learn how to hack... go ahead and post if you need to hack something or "PM" (personal message) me if you need any assistance. Remember this group is to unite us so we can gather each others intelligence so one day you cn say "HEY I KNOW HOW TO DO THAT!!! AND IM A KID/TEEN!!! :D" *Please dont abuse this privilage*

Want to ditch this mortal coil, but not all the way? Curious to see what your face will look like as the flesh begins to peel off of it? Then you might want to check out Rob Sacchetto's site where you can submit a photo and he'll draw an undead version of you and send you the print. The sample pics on his site look suitably gross enough to merit the $80 price tag. Zombie Portraitsvia Drawn!

I've noticed that there are a lot of instructables about making kites and making stuff to get pulled by your kite. But they all seem to assume one already knows how to kitesurf/control the dang kite, which is kind of an issue for people like me. I'd like to see an instructable with photos (maybe even video) of how to kitesurf, specifically omving the kite around and getting pull in various directions. With explaination in plain english of the headache-inducing technical terms. Sorry, but when I googled directions all I got was more confused. Of course, I'm thousands of miles from the nearest ocean, so I won't be doing this on the water probably (are reservoirs big enough?). In fact, I plan on learning all I can about how to control a kite so that I can go tool around out on the plains on a mountain board type thing. P.S. On a mountain board, do the trucks flex and turn the wheels somewhat like on a skateboard, or can I mount them rigid?

I teach music in Elementary school(s) and have a class with several special needs students. I'd like to make a music note generator like a simple keyboard but I want to use buttons they already have. Example. While the rest of the class is playing recorder. These students have a large piece of black poster board with several round dots with note names. While the group plays these students push on the round dots. I would really like to be able to make those dots play the same pitch as the recorders. Just one simple sound with about 6 or 7 different notes. i.e. from D to low D or C. Did I mention that this should be cheep too? (- Thanks, Carmine

Hello Friends, Decorative traverse rods are one way to accentuate your windows with drapery. Traverse rods enable you to open and close the drapes with a pull cord. Sometimes one or more of the rings breaks requiring replacement. Unfortunately replacing rings requires removing the traverse rod from the window. Taking down a traverse decorative rod enables you to separate the rod and remove the faulty rings. Unlike standard rods, the traverse rod fits inside a channel clip across the top of the mounting brackets. Unhook the drapes from the traverse rod master carrier. The drapes hang on metal hooks that lift out of holes in the traverse rod. Hold one end of the traverse rod with one hand and turn the decorative end cap counterclockwise with your free hand. Remove the end caps on both ends in this manner. Find the screw on the retaining clips securing the rod to the mounting clips. There is a mounting clip on each end and one in the center. Remove the screws with a Phillips-head screwdriver. Grasp the center of the rod and lift straight up to remove it from the brackets. Pull the rod away from the wall. Thanks and Regards, Baron Davis

My friend and I are considering building a spring loaded cannon. The idea right now is to have a pvc pipe for the cannon chamber, and pvc pipes flanking it to hold springs in parallel. A cross-bar will go through all 3 pipes through slits cut long ways in the pipe. The springs will be attached to some point forward in the flanking pipes and to the cross bar, which will be used to pull the springs back and, once released, will launch the dart/ball in the center tube. My research so far - the spring rates of springs loaded in parallel are additive. With 5x 10-in*lb springs, we can produce 667 newtons of force when pulled back 3 inches (springs in question are 5.5 in long) . That will produce an acceleration of 303 m*s^2 on a 1 lb (2.2 kg) albeit for only a fraction of a second. http://www.amazon.com/Extension-Spring-5-625-Long-080-count/dp/B001292S08/ref=sr_1_1?ie=UTF8&s;=industrial&qid;=1257718057&sr;=1-1 These are the springs we're looking at. We'll need to use an even number of springs, so either 4 or 6 (or 8 or 10). So, what do you guys think? Practical? Will we be able to get any distance? Any suggestions? A ROUGH picture is shown below. === are spring tubes, | are handles, and left arrows indicate direction in which springs will be stretched, and the right arrow is a dart flying out of the center launch tube. <----| ===== XXXXXXXXX ------> ===== <----|

5 DOF Robotic Mechanical ARM Required Material of project:- 1. Basic Servo Tower pro 9g*4 2. Header pins Male female*2 3. Arduino Nano*1 4.10kΩ Resistor resistance*2 5. Trimmer Potentiometer track Linear; maximum resistance 10kΩ*4 6. Tactile push button*2 7. Blank circuit board*1 8. Acrylic strips for Robot & potentiometer body*2 9. Wires, Button, Switch 10.Balsa wood, Metal, Plastic Procedure:- Arrange all necessary items.. Please go through the attached images for better understanding.. I divide whole project in two parts 1) Servo Motor assembly 2) Potentiometer assembly 1) Servo motor assembly: – Servo motor as J1, J2, J3, J4 fix the servo motors as shown in image use 3M tape to glue servo, use thin flexible plastic strip to make griper, make hole in center of each finger tie thread in that hole pass this thread from center hole and tie knot at the other end of thread with 4th servo motor’s knob, as you stretch thread finger get close vise versa. Fix whole arrangement on strong rigid base. 2) Potentiometer assembly: – Fix potentiometer as shown in figure name potentiometer as do previous R3, R4, R5, R6 this time place R6 separately for easy access this potentiometer control gripper to pick and place. Potentiometer arrangement symmetry must be same as servo arm. Fix whole arrangement on strong rigid base. Moving a little bolt from one side to the other side:- 1. Actuators / output devices: 4 micro servos 2. Control method: controlled by a PIC16F690 assembler firmware 3. CPU: PIC16f690 micro controller 4. Operating system: self made assembler code 5. Power source: 4.8V to 6V from 4 battery cells 6. Programming language: PIC Assembler 7. Sensors / input devices: teach in system with 4 potentiometers Making Processer:- The Potis are standard types and are screwed to the white plastic parts with their nuts. The axles are pressed into the transparent plastic part. The handle to move the teach-in-arm is a M3-Spacer and the socket is a plastic part with is normally used to fix balloons on a stick to hold it. move the motor itself by hand a little force is needed due to its permanent magnets, which create a small holding force. But inside the servo a lot of gears increase the force which you have to apply. If you move the servo by hand, you have to apply a much higher force. If you overcome the motors holding force, it starts to rotate an acts as a flywheel. So moving a servo by hand needs a high torque and its not easy to turn it to the position where you want it. ( Fan control modules for engine cooling of real cars have some extra parts to clamp the voltage which is generated, when you drive at higher speeds. In that case the fan works like a windmill and creates higher voltages than normal inside the power stage of the module.) And there were also a lot of other "problems" which had to be solved using my PIC Controllers. i.e. self made electronics for a RC-Excavator which works similar to the digital system used in slot cars. To replace a lot of wires between the rotating part of the excavator and the track unit, a small PIC 12F629 reads the pulses from up to 5 channels of a RC-Receiver and leads their information via a 2 wire connection to a second PIC12F629. At the second board the power is separated from the data. The PIC is reading the data, and generates the PWM output for the 5 Servo output connector. the 2 wire connection is made with a cheap 6,3mm mono microphone plug which is also used as the axle for the rotating part. The arm of the excavator is also powered by standard servos and so it was necessary to change the control behavior from proportional to integral so that the servos move like real hydraulic cylinders which are controlled by valves. I used the same 12F629 type for that job and added some features like adjustable limit positions and starting point programmable by one jumper, and automatic return to park position when missing the pulses for some seconds. The Software is simple:- Its working like a servotester for four axis. That means, every poti is connected to an analog in of the controller and all servos are connected to GPIOs. The controller reads each poti, does some scaling, so that the angle of the poti equals to the angle of the axis and finally he creates the PWM output 1-2ms pulse every 20ms for all servos. Teach mode:- After a reset the robot arm follows the teach in arm while simple mapping the analog inputs every 25ms to the servo motors. Pressing the button stores each servo position in a array. Play mode: The sketch reads the array step by step and moves the robot arm. For cool looking movements I added a routine calculates different micro steps for each servo to have moving start and end sync on all axis. Also added a ramp for soft increase/decrease velocity. Shorter travel distances the robot does slow, longer distances with faster speed. The program moves the servos at full speed to the next position and a short delay time after each command allows all of the servos to reach their final position. That means that it is possible to increase the speed a little bit more by doing some fine tuning of the delay times after each command. The final thing which is still not implemented is the routine which saves the "Teach In" data 5 or 10 times per second, so that the controller is able to replay it in a loop with the original speed or with a lower or higher speed. Electrical Connection:- Provide separate power supply (5V DC 1amps) to the Servo motors . Don’t forget to short ground of both power source ( arduino + servo) 5 DOF Robotic Mechanical ARM :- 1. Use of Fiber on upper side 2. wooden spoon is a part of side body 3. cable tie *12 pieces use the robotic. 4. Some pices of wires 5. use scraw*4 6. Glue 7. some small clips Because to attached body 8. small size of plastic box 9. One pieces of square fiber stand and one pieces small & medium circular fiber 10. L293D Motor Driver IC+IC Base KG143 11. Generic Elementz High Quality Nickel Plated 24*18 Points Bread Board*(2 pieces) and one plastic 12. Push Button Switch. Play Mode version 1.1 The gripper input is used to set the delay (0,1,3,15,60,300 seconds) after a loop is done. The switch (it was left from the project start) pauses the robot. Thanks you:

I tend to write the titles of my 'ibles as if the phrase "How to..." was already there. Thus: Get Any Information... Knit replacement pads... etc. I notice, though, that most of the Burning Questions begin with "How to..." This suggests that people are searching using those words. So, should I change all my titles to start that way, or just leave them as-is?

I was wondering how you could make them. Guides are just lists of notable instructables for a certain category, And I was wondering how I could make my own guides. It could be a special power/privilege that only certain people have, but after seeing the plastic bags guide, im not so certain......

I'm not quite sure what's brought me to asking y'all how tall you are, and I'm not sure why I care this much, but how tall are you? I'm 13 years old, and 6 foot tall, without shoes. I'm taller than most of my teachers, and only a few other kids are my height or taller. People literally look up to me. So, if y'all could post your heights, I'd sure like to know!

Hi all, I hope everyone is well. I have 2 circuits here and was wondering if someone would show me how to connected them, it is probably very simple, but I just want to be sure. here are the 2 schematics I'll be working with... I assume I just use a common ground... but we all not what assuming makes us :) Thanks all in advance,

I saw a wallet made from an iPod somewhere on the internet. It was a video one with the click wheel still intact and the person's ID showing through the video part. Any help with finding how to do this would be greatly appreciated.

We all went to school sometime, right? I bet more than half of you are still in school. School School Schooooooooool. We all hate it. We all know it. And yet, we still go there. It's like death, but without dying right? Yeah. Actually, no. I went a bit over the top, but it's bad. I'd rather be here, making and sharing instructables than there, doing algebra. So, what I'm trying to say is: SCHOOL IS UNAVOIDABLE BUT IT CAN BE EASIER! That's our motto here and we're STICKIN' to it! (Unless someone comes up with a better one. >.>) So, thanks guys! I'll be posting the rules, guidelines and how to become a "School Basher". I'll let you know EVERYTHING. Thanks.

I am wanting to make some sulphuric acid because it is on of the most useful acids around and i have ran into a problem. after you burn sulphur to create sulphur dioxide you then need a catalyst to form sulphur trioxide and then dissolve in water. which catalysts could be used and could you just let the sulphur dioxide dissolve in hydrogen peroxide (so2-----so3------h20--------h2so4 or so2 ------ h202---------h2so4).if this would work how could you get a large enough concentration of hydrogen peroxide?

Carlos Alcala, the author of FYIs for the DIYers sent me this awesome email he received in response to his article about Instructables:Carlos -- Great article on Instructables.com! My 18 yo son discovered this site a few years ago and has made good use his find. He has made some amazing masks and costumes (he is an actor) and finds all sorts of things on that website.Funny story: His 16 yo sister recently came to him with a problem -- she now has her first serious boyfriend, but is nervous because, in her words, "I don't know how to kiss!" Since he has had a few girlfriends, she asked if he would he explain it to her. BUT... she didn't want to hear too much because the topic embarrassed her so much. What did he do? -- Directed his sister to Instructables.com, of course! I just laughed and laughed when she told me this -- I had no idea they covered kissing on that site! AmyIn case you need it: How to Kiss.
