I already asked a question about three-phase power but my results only confirmed what I thought. I don't understand how a MOTOR can run at 230v with three phases, how do they rate power with these I guess. 230v outlets have three prongs, I think two are connected to the generator through power transmission lines, and one is a ground. If this is wrong were do they get 230v because, if I am wrong all three wires connect to generator coils. This would add up to 345v. But to get 230v it would only be two phases. Then it can also run on 480v, how in the world do you get to 480v. Please help me with this.

So I got a free 3 month pro membership from my Instructable, https://www.instructables.com/id/How-To-Revive-Dead-Highlighters/, being featured. But then I got another email saying that I got another free 3 month pro membership. So when my first3 month pro membership expires, will I be able to use the other 3 month pro membership or do they both count as 1 3 month pro membership all together?

I am just curious as to what I might need, if any for a resistor. I plan to run 3 white LED's, using a single 9v. I jumped ahead and hooked up one set to see how it works, and it seems to work great, each LED is packaged as running at 3.2v, so I figured 3 would be alright on a 9v battery. Is a resistor required or necessary if I multiply in this manner?

I am trying to make sense of how to create a simple 3 phase inverter, but the design I have found requires the use of a PIC micro controller for pulsed width modulation to control the 3 half inverters in the image below. I do not have experience with this specific type of micro controller and am unable to find a simple explanation of how to set it up to do this, except how to connect it to the basic circuit at the transistor bases. Would anyone be able to explain to me how to wire/program/control frequency with the pic micro controller or an alternative method that would yield 3 phase power (0-120-240) because the manual and this page have be very very hard to understand to a beginner. I do not need any sort of feedback from the motor because the load will be constant and relatively small, and will most likely run it either at a constant or if easily doable linearly increasing frequency. Can someone PLEASE give me a good simple set of instructions on how to either replace this micro controller with something simpler or wire/program it to do this? Thanks!

I am looking to add a 3 stage light timer to my shooting range at home and am wondering if anyone would know of something similar to this that has been done or possibly some help setting it up. I have seen that an Arduino may be able to do what I need? I am looking to have 3 lights, red, green, and yellow. I want the red light to be on all the time. One a button/switch is hit, the red light goes off and the green comes on for 2.5 minutes. Then the yellow light comes on for 30 seconds. Then the red comes back on until the button/switch is activated again. Any pointers or suggestions would be very helpful. Thank you.

I recently purchased 13- 3 watt LED's. I'm trying to establish a high out-put LED light. I also purchased a LED Driver Transformer 48 Watt 120 Volt to 12v DC 4 Amp. First I would like to test each LED using the same divider. I'm thinking that if I create a voltage divider two 330 ohms to limit the current and reduce the voltage to about 6 volts that would allow me to test with the driver that I purchased. Secondly, will this driver be enough to drive all my LED's and would I have to reduce the voltage down too since it appears to push out enough wattage and amperage for the total number LED's I'm putting together? I'm building my circuit based on this video. http://www.youtube.com/watch?v=4qYZahe2s5o&NR;=1 Link to website data of 3 Watt LED. http://ledsupply.com/indusstar-1up.php Assistance would be greatly appreciated.

Hello everyone! I was hoping someone here with better understanding of engineering or just a fresh take on the problem can help me out. Im working on this art project where I have a metal ball, aproximatelly the size of a basket ball, and i wanted to make it rotate continuously on a stand, in a way that all sides of the ball were shown eventually. I've thought about this 3 axis sytem where each axis would rotate in turns to keep the ball rolling in diferent directions. Basically its like the insides of an analog mouse where the ball would rotate the gears and give the input of the location of the pointer, except here the gears should rotate the ball. I've been trying to build something close to that with some K'NEX and a simple rotation engine that came with it but im not getting nowhere. I thought of building the gears myself but im finding it hard to come up with a plan. What would the gears be shaped like? What size? what distance between them? Even with trial and error would take me forever @.@ Anyways, any input, ideas, comments apreciated, Thx!

For a class I'm taking, I need to make a speech in 3 minutes that demonstrates how to do something. It could be something very simple, but being the person that I am I want it to be at least mildly impressive. My hunch was to do something computing related with my eeepc and a projector, but that idea got nixed. I'm also interested in electronics, though, and I have a lot of stuff in my junk box. Anyway, I'm not asking anyone to do my work for me, this is more about presentation skills. But if you happen to have an idea of what I can do quickly and with minimal likelihood of failure I'd be eternally grateful.

In hopes of seeing more paper airplanes and innovative designers on Instructables.com, I have decided to host a third mini-contest. My goal is to stimulate the paper airplane channel and encourage more paper airplane builders to post their innovative designs. For this contest, the specification is for a stunt plane. Requirements: 1. Aircraft Requirements: • Ability to perform a loop, wingover and/or a Cuban eight • Durability to fly at least 15 flights • Use of less than 15 inches (0.381 meters) of tape in construction • Use of less than 5 pieces of 8.5 by 11 inch (A4) paper in construction 2. Instructables Requirements: • 1 page strictly devoted to materials required in construction • 1 page explaining how to fly the aircraft • The instructable's license must be: "Attribution Non-commercial Share Alike (by-nc-sa)" • This sentence and link must be displayed on your entry's intro page: “This instructable is an entry in Paper Airplane Contest 3 (https://www.instructables.com/community/Paper-Airplane-Contest-3-Open/).” Prizes: For this contest I will award the publishers of the top 5 performing paper airplanes* one patch each. The first place winner will also receive a 3 month Pro membership. These patches will be medals (1st place, Patch with Gold Medal image and 3 month Pro membership; 2nd Place, Patch with Silver Medal image; 3rd Place, Patch with Bronze Medal Image; 4th Place, Patch with 4th Place lettering; 5th Place, Patch with 5th Place lettering). *Multiple entries are allowed. To keep the distribution of patches wide however, each entrant can only win one prize. How To Enter: To enter this contest, you must send me a private message entitled “My Paper Airplane [Member Name Here]” with your instructable's URL included. I will then put the link and author's name onto a list on this topic under "Current Entries". Judging: For this contest, I have decided that I will judge all the planes myself based on abilities. I have decided this way because I believe judging on performance rather than shape is a more objective approach. The contest begins Monday, March 14, 2011 and ends Friday, April 8, 2011. Entries must be published before Friday, April 8, 2011. From April 8 to April 11, I will be judging all entries.

I am a total beginner, having logged about one hour here (the last hour). Does this sound OK for a first Arduino project? I want to sample and log the temperature outside at the surface and at depth for a total of 4 readings to a depth of around 50cm (20"). The reason is to consider if I should provide my daughter's pet rabbits with an underground burrow as relief against the next heat wave. It seems a nicer option than running a swamp cooler all day. Though I suppose I could use an Arduino + LM35 to turn on and off the swamp cooler :) It looks like I can do it with 4 x LM35s, an Arduino One, some sort of data storage, a 9v battery and a bread board. Any recommendations for if I should use WiFi or an SD card for storage? My guess is the SD card is simpler to programme and maybe less of a battery drain. It seems I just need to hook up the data out of the LM35s to the analogue ports, then loop over the inputs and write the outputs to a file somewhere. And calibration too. Any pointers on how to turn the LM35s into probes that can be buried in the ground? I was thinking I could bind all the probes onto a dowel, dig a hole and bury it. How to extend the LM35 pin outs? Thanks in advance for any suggestions.

I was looking through the MANY guides on the web for weldernators and I'm in the midst of putting it together. It suddenly occurred to me that my dad used to own both 5 and 3 phase AC welders and I thought "wait a minute, an alternator is 3 phase AC". I searched and searched but I'm doing a lot of searching on a smartphone because of a really long couple of work weeks, plus I suck at Google apparently. (If I wanted to buy one I could find that.) Anyway, I'm just not sure of how a 3 phase AC welder works. Maybe it just turns it into DC. They were just arc welders anyway.

I was meaning to post this sooner but completely forgot. Anyway, If you don't already know, Guitar Hero 3 Legends of Rock for the Wii has a disk flaw. The flaw makes the sound in mono instead of the Dobly Digital Surround Sound that is advertised on the box. Activision will replace it for free though. The way you can tell if you have a flawed version of the disk is if you look right above the Activision logo and if theres a little white star there or not. If there is one you have the new version and don't need a replacement. If not you can go here, fill out the form and then they will send you an envelope for you to put your old one in and send back and then finally you get sent a new version. I just thought I'd let you know. Good Luck!--Note-- If you send them a disk thats anything other than the old version of the Wii GH3 game they won't send anything back.

I have currently started building a 3 axis rotating Flight simulation rig that can simulated any 3D motion with a pilot inside the main cabin in control. I know the project needs a lot of disciplines working together (Steel design-mechanics-electrical-electronics-control-programming) So I assembled a team of engineers who got interested in the idea but we are not all highly experienced and the issue is new to all of us. So far we managed to design the rig it self as in steel design area. when we started moving along to the next phase which is the mechanical parts and joints we faced a lot of issues regarding the weight and balance of the rigs. The attached image is for a flight simulator done by a company in Russia. We have great ideas for improving that design and building our own non expensive simulator. I didn't post our full design model done in solid works cause it's not yet perfected. All I asking is that , if there is any one out there willing to help us share the knowledge or has a bit of experience in the subject, or wants to join our collaborate work, please don't hesitate to contacts us. I don't know the forum rules so I won't post my contact information here, but please feel free to discuss the subject with us on the forum, so we might benefit all together from this experience.
