How to connect to ac the motor has 7 pins wich pin2 and 3 are brushes .need some help please
Question by RediÇ1 | last reply
I have a photovoltaic panel and I want to connect it to the AC power line of my house. To connect it to the electrical panel of the house I should use long wires. So I thought: "Is it possible to plug it into the nearest wall socket?" Of course I don't want to put straightway DC from the photovoltaic panel into the AC power line... what I mean is to plug the output from an inverter into the wall socket. Is the inverter supposed to adjust the phase of its output current to match the mains' phase? Should I look for a particular kind of inverter? Thanks for your answers EDIT: Doing further research I found that a company sells photovoltaic systems that you can plug into the wall socket. So in theory it should be doable, but as rickharris pointed out, it seems that it would cost more than I'm ready to spend. Probably I had better resort to plan B: connecting the solar panel to an inverter, snaking wires through the walls and adding another receptacle to an existing electrical outlet. Thanks to all of you

Can any one point me in the right direction on remote controls. I have a lift installed in my van for my wheel chair. The chair and lift total is about 400 pounds. I have a guy tell my that it would take a special unit to lift that much. The lift has all the motors necessary to operate it. I only want to run the motors remotely because of the way the wires keep getting caught in the lift. Can anyony help me? Thank you in advance for any you can give.

Hey, I wanted to build an alarm clock with multiple, customized sound effects that could be chosen instead of randomized. I'm really new to instructables, and electronics in general, but I've thinking about this project for a long time and I'm willing to learn just about anything to get it done. Where can I find an instructable or link that will point me the way? Thanks!

I'm a blacksmith in training and i need some coal, i want some, i don't need it but it would help a ton. my father keeps saying that i can get 1000 lbs of coal for $100 but so far, it's all 50 lb bags for $20 on http://www.centaurforge.com, some 12 lbs for $20 on some remote website somewhere someplace in some far recess of the pixelated world of the internet!!! ... i don't mind paying $200 for 1000 lbs, or even a bit more but the problem is, is that i'm in Florida right now. so, i don't know how to get coal cheaper than a buck a pound. right now i'm using lump charcoal and it works fine. but coal gets the metal a bit hotter. so what do i do.

It seems like my Instructables dashboard used to have a button, or a link, pointing into unpublished, draft 'ibles, I might be working on. Is there a button, or a link for that, somewhere? For to show a user all of the unpublished 'ibles that he or she is currently editing, but has not published?I have noticed that an URL of the form,/editInstructable/edit/123456789ABCDEF/step/0will tell the ible-editor to open that particular draft, where "123456789ABCDEF" is a length-15 string of [0-9] and [A-Z] that, I guess, uniquely identifies that draft 'ible.Maybe we are all just supposed to bookmark, or make a note of that URL, while writing a new 'ible. Either that, or never close the browser while working on a new 'ible.

The leds will have 4 statespassiv- The green is pulsing Stand by- if switch a is flipped, both leds are activated. It is also awaiting and wireless signal. to chang state charging- When it revives the signal "start charging" and the switch is activated, the green led is activated fully. Problem- if the system revives the signal "problem" only the red led is activated, regardless of other signals.The signals "start charging" and "problem" are going to, in best case, be controlled by an user with an app.So my questions are...1: would my plan work. 2: How would i do the weiring3: Could make the program by just an simpel if-else4: What would i need to change if i whant two seperat led setupps. to be controlld by the same Raspberry Pi

Well now we are ready to have all 200 brick removed and new ones put in. We found out the manufacture of this type of brick no longer makes them. So I thought maybe we could fined a brick that has the same texture and then paint the whole house. We have been looking and haven't found any.

Hello. Pardon me for troubling you with this question. It's just repairing my old headset and I wanted to at least make it work again. I have a few headsets on my shelf because of the loose connection in the audio jack so I tend to buy another one instead. But now I thought I should try to fix it. Then a while ago I was able to make it work but only in the right channel. The left channel has a lower volume output. I provided some pics to show the headset I'm working on and the connections I made. The red wire is in the lower pin. The green wire is in the middle pin and the blue one is in the top pin. The ground is in the longer pin with the lock. Sorry for the image quality. Is there something wrong with the connections I made?p.s. I also wanted the microphone to work too.

How can I turn my Loft Bed wooden ladder into a climbing ramp for my small 19 pound dog to climb up into the loft bed? I have a nice wooden ladder to the loft bed, but the wooden rungs are about 10" apart -too far for my small dog to climb up that 45 degree angle Any ideas? OR ideas for a long enough dog ramp/stairs (I do not see any long enough for sale anywhere that would reach a loft bed ---and not be too steep.) The longest ones I have seen available seem to reach from the ground to the tailgate or the back of a truck or the like. I thought of adding a layer of carpeting to the loft bed ladder, with possibly some kind of strips for my small, agile 19 pound Mini Eskimo mix dog. She is usually cautiously timid of unstable situations or obstacles in her way, although she jumps easily from the floor to regular height bed. Also, I guess i will need to be able to lift up or off whatever dog climbing material I put on it, so that I can convert it back to something I can climb up into the loft bed too! Unless I build something (maybe from sturdy shipping boxes covered in carpet (I have plenty of carpeting that I could cover a series of large rectangular somehow strung together and that would be flexible (kind of like a roll-out fire-escape ladder is flexible) the rectangular boxes when sealed are quite strong and light weight, and that would be light weight enough to flip up or down, but I need help on the engineering part of designing and constructing something from boxes or long pieces of carpeting or or from the human wooden loft ladder to make it more dog-friendly. Any ideas, or am I just an unrealistic dreamer?

Instructable's is my favourite website/platform/community period. As an Engineer on Instructables I would really like to see a Open-Source API so that developer and engineers can access data & statistics from their Instructables easily. The main reason for which I would like to see an API is so that I can create physical notifications(LED light bulbs) every-time someone Favourites or Comments on My Instructable. I guess you could create an IFTTT channel for Instructables(triggers like comment,favourite,inbox,etc.). I'm curious to know if there is a Instructables API in the making? I'm sure there are other Engineers & developers in the Instructables community who would like to see an Isntructables API. If you have any ideas as to what the Instructables API(if Instructables HQ decides to make an API) should include leave it in the comments. I'm sure they would like to hear some of our ideas.

I've never worked with concrete before but I have a burning passion to make an usu which is more or less a giant mortar about 1 1/2 foot deep and 2 feet wide in the inside diameter that uses giant mallets as a pestles to pound sweet rice into mochi. What I need to know is what kind concrete will be able to hold up to hot steaming rice and constant impact with wooden mallets without cracking or chipping. My idea is to cut a garbage can down to the height I need and to use a styrofoam mold that are the diamentions of the hole I need. Do I need some kind of release agent or will the water evaporating from the concrete shrink it enough to allow the styrofoam to be taken out?

This needs a bit of background info. I found this amplifier a year ago in the streets, by the trash, and I took it with me cause I like to open up things and see what I could get (it was obviously broken). I opened it up, and started looking at the parts. The connections are old-school, first time seeing those. I noticed that one cable was not connected, so I took care of it, and tried to power it up. For my surprise it worked, and I had to secure the plug, which had only red and black (+ & - I guess). Fast forward to now, I heard or read that anything connected to a plug should have the ground as well, especially if it had something metal. The amplifier is made of metal on the sides. I'm giving it to my uncle, but I don't want to give him in a dangerous state, so, should I change the plug again and put one with the 3 wires? How or where do I connect the ground? (I saw one connected to a screw in the metal part once) And most important, why? Thanks a lot, sorry for length and for possible grammar or vocabulary mistakes. TL;DR: Found an amplifier without plug, should I put one with ground? How? Where? and Why? THANKS!! I've got answers saying that ground on audio systems are complicated and I've been reading but it's so confusing, and I don't understand it pretty well... THANKS IN ADVANCE TO ANYONE GIVING ME SOME INPUT, I REALLY APPRECIATE IT!! :D

We recently bought a secondhand InStep brand bike trailer to haul the kids around in. It came with one coupler.

I've looked at several trailer coupler Instructables, but none of them seem like they'd work with this trailer"s tongue, and I don't want to modify it, since it works just fine with the existing coupler. Any suggestions for a way to make a good, strong, secure coupler?
