Hello guys, in my first "instructable" I want to show you some pictures from when I first begun to meditate. I remember those days very clearly, like it was yesterday. At the age of 22 I was feeling very depressed and sad, and nothing was going right for me. I did not know what to do and I was very confused. I started to look here and there for answers for different questions but nothing was satisfactory. I was really unhappy. Until one day, when a good and old friend of mine send me a movie about meditation and how to meditate efficiently. In that day, my life took an incredible turn. I watched that movie with great curiosity and I was amazed by the benefits of meditation. As soon as the movie ended, I knew that this is the answer that I was searching for. I started to inform myself more and more about this ancient technique, and in only few days after I have seen the movie, I begun to practice meditation. I put in practice all the knowledge and information that I have gathered in the last days, and in a week I have already started to feel a lot better. Some old problems have already started to vanish, my depression was almost healed because of the answers and different states that meditation offered me. Above all, I was able to eliminate all of my selfishness and egotism from my behavior, which was a very important for me. So I really recommend meditation to every person on Earth. Reflecting on nature beauty can be a perfect method to meditate!

Meditation Timer

I'd like to modify a simple egg timer for meditation.  My current timer makes loud harsh staccato beeps.  I'd really like a timer that made something that sounds like a long slow deep bell when the time is up. I have no idea how to do this but I'm guessing someone does and can do it for less than the $100 ones they sell in the glossy Buddhist catalogs.  Any help would be great

Haptic Feedback Meditation (E-Meditation)

Hello, I am a 17 year old electronic hobbyist. I am in the process of making a "Haptic Feedback" meditation device. I give the whole project story here. If you are just interested in the final project you can skim or skip to the "Testing" section. THE IDEA Many months ago (when i was not so knowledgeable about electronics) I had an idea. I wanted to be able to see my thoughts as I thought them. I was obsessed with the idea of this and the thought of what would happen( imagine holding up a microphone to a pair of speakers). I could imagine myself staring at my own thoughts (or a colorful representation of them) for hours. I imagined it to be a "New Generation" of meditation. I drew up a few sketches of what this would look like and.. I hit a wall. At the time. I knew absolutely no way to do this. I just knew it was possible. I put the project on the back burner. CONSTRUCTION Six months passed and I had gotten better and better at electronics and micro-controllers and such. A month ago, I started obsessing over it again. I did some internet searches about this type of technology and all the gibberish started making sense. Not before long. I had ordered the parts for it. It cost me a good 100 dollars in birthday money. But it was well worth it and i do not regret the purchase's at all. The three main pieces were a Micro-controller(arduion uno), a brain-wave reading headset(from an expensive childs toy) and a 7 inch by 3 inch RGB led panel( a fancy panel that makes different colors and patterns). Despite knowing a little bit about electronics I was out of my depth, yet still addicted to the project. Long story longer, I had tested the three pieces of technology and they all worked beautifully. With my limited supplies i busted open the headset, made some solder joints, plugged it into the micro-controller, plugged the micro-controller into the computer, and plugged the brain reader into me. Someone before me had already made sample brain viewing  programs in the processing language for these kinds of projects and i downloaded it. I turned on the program and flinched as i turned on the headset( being plugged into your laptops battery can be a tad unnerving). I was looking at a graph of my brainwaves in a system of line graphs and bars. TESTING This was exciting stuff. I sat there for perhaps an hour just staring at my brainwaves shortly noticing a pattern emerging from just simply staring at even the brain reading program. I noticed the more I stared at my brainwaves looking for the next sudden jump or dip. The less they did. In other words, actively TRYING to move my brainwaves, almost completely nullified them. This was very interesting. I took the device and my laptop to my school To get an accurate sample, I allowed any and everyone who wanted plug themselves in to go right ahead. As they messed with thier hair to get it to fit right and turned it on. What was seen for a few seconds was a (what I consider healthy) measure of brain activity. Everything was jumping up and down at varying levels. But after the subject began staring at this dance. The brain activity shrank and shrank until little was left to be observed. Occasionally depending on the situation the subject would then get bored with the lack of activity and try and make some sort of small talk. It then showed a small rising in overall brainwaves that was immediately crushed by the subjects attention toward the screen. In the initial planning, this was the last possibility I had considered. With accidental electrocution being higher on my list of possibilities. The grandiose plan of mixing my thoughts and ideas in front of my eyes shrank. I was loving every second of it. I then later plugged the panel into the device and began writing code to make it react the way i wanted it to. I had programmed the panel to display the color blue when meditation was high and red when attention was high. Purple would occur during a balance of the two. I then took out my computer from the equation as a reader and decided to see what would happen by just watching these two stats work themselves out on a color panel. I got similar results. When I was actively attempting to meditate while simultaneously watching my level of meditation it was an unwavering red. Deep breaths and glances away from the panel would bring purple to blue colors. Then I tried something completely different. I attempted to radiate unconditional love for my brainwaves. I accepted them for their want to be attentive and alert. And embraced them with as much sincerity as I could. The panel turned purple and stayed blue for as long as i could keep this state up without wavering. "Wow" i remember remarking. I may have created the worlds first "Unconditional Love bench press". And your up to speed. FUTURE I have some ideas for the future of this project but I have caught myself in a mental enigma. How would one meditate to the thoughts of their meditation without their monitoring of the brainwaves getting in the way? Or have I missed the point of meditation which might be to have no thoughts? Ideas and suggestions would be great. I would love to hear what this community would have to offer to this device. Input on meditation? Input on the technical stuff? All is welcome.

Questions from a beginner in electronics/DIY.

Hey all! I am trying to get started in electronics and don't know how to begin. I have done some basic soldering and junk and made really basic stuff but i want to actually learn about electronics. I want to learn how a transistor amplifies current and how to design a circuit to do a task on my own. I want to do projects as a move along but the Make book on beginning electronics isn't what i am looking for, for one it is really expensive to get the pieces with it and second i also want the theory behind it not just the how to build. I hear The Art of Electronics is good but it is over 1000 pages and most of it is extremely bland! I just want a good couple hundred page book that will teach me all the basics of electronics as well as show me some neat projects to do. (also what should i buy after i master the basics?) I also want to know how you guys got your workshops up and running. I see so many posts about people just casually saying that they took their dremmel to a sheet of plexiglass. I don't own any plexiglass and i sure as hell don't own a dremmel. I feel like there are SO many cool projects that i simply will never be able to build because it reuires a custom made wodden box, or this or that, what have you. How do most people on here think of that? Do you guys all have workshops will all these tools? How does a beginner go about not getting overwhelmed when a neat project calls for some custom made piece and thinks "well there goes that project! I will NEVER be able to make one of those! I dont have the machining experience or the tools!"? My third question is what tools i will need to get into electronics. I have a soldering iron but i don't know what else i should get. The obvious tools are multimeter, wire cutters, wire strippers, etc. What are the best brands and where do i get these? What do i do about components? Do you guys just have a place where you have all your components that you might need on hand and only order specific ones? For instance, should i order a bunch of transistors, capacitors, potentiometers, etc and just organize them so i have them to pull out when a project calls for it? Or should i do things on a project-by-project basis? Also how do you organize all your components? What are some good commercial organization bins and what techniques do you guys use? (preferably i want a drawer-type organization, not a bag type). Also should i purchase and arduino? I am not new to programming (i know C, and Python) but is it the right time to purchase one as a beginner? I see all this talk about using a specific "shield" for a project and i get uncomfortable thinking that i can't do anything with just and arduino. Also i dont want to have to dismantle a project if it relies on a microcontroller but I really dont want to have to buy an arduino for each project i do! How do you reconcile this? Sorry for so many questions but i am excited to get started

Linear magnetmotor - the basics for a beginner

Designing what is said to be impossible can be tricky, so I will try to give you some tips to reach your goal a bit quicker.A lot of people these days try to start with a wheel.Makes sense in one way as the final goal obviously is something that would rotate.However, considering angles in a rotating system is far easier with a usable baseline!We developed the liear motor well after any rotating electric motor.But only because someone already invented it for us.Making it flat was then more or less about finding a need for it first, like the modern highspeed trains on a maglev principle.If you want to make something move then it makes no big difference if you do it in flat or round.Flat however leaves you more options and much easier adjustments.And you will need a lot of the later...IMHO the best size and option for linear is the N0 model railway system.Tracks are only 3CM wide and second hand carriages to salvage the wheels is cheap.Either way, how would you start?We have multiple choices, like single row of magnets or double, maybe even tripple.Same for the actual magnet orientation.Flat, angled, attracting or repulsing...They all work if you understand how they actually work.Not the principle, the magnets ;)You see, a magnet always has two poles and without trickery both poles will be of even strenght, size, angle to each other and so on.Playing on a small and flat track with little resistance allows to use tiny magnets, like 5mm disc ones.If you follow the common concept of two magnet rows either side at a slight angle then you are half way there.People spent a lot of time trying not only to let the cart being attracted by the first magnets but also to let them pass out at the other end.In case you wonder why:Being able to be "sucked" in means you will have some force pulling on your cart from the next stage.Being able to fully pass through and preferably gain speed, means the cart would go from one set of magnets to the next - motion is accomplished.Let me give you my personal favourites for 5mm disc magnets:1. The rows are at an angle of 4-5° like a slim V-shape.2. Same as above by with the orientation changed by 90°The first basically means you have the magnets facing up while in the second you would have them mounted vertically.Both have good and bad sides and I think it is easiest to start with the first option.Here you would have a row of magnets at a slight angle either side of the track.Lets say it is all pointing away from you, then the north row would be left, south row on the right of the track.If you start narrow or wide depends if you want attraction or repulsion forces to work with.Again, it makes no big difference really, just a different way of operation, most seem to prefer repulsion though thinking the forces are greater - this is not true though ;)A very often copied way of mounting the working magnet (s) on the cart is by placing a magnet with south facing down on the left and one with north facing down on the right of the cart.Here you have the big problem of manipulating fields.The forces are quite strong and it seems the obvious choice but should be left for the advanced classes.Let me try to explain:No matter the site of your work magnet it has a very narrow acting field.Means you have a lot of attraction forces going only downwards and not providing any energy to move your system ;)If you orientate a magnet (stack) so north faces to the right and south to the left on either side of the cart you have more options.If the stack or single magnet has the correct length to match the angle of the magnet rows then a funny thing happens.Assume the outer most magnet is at about the same distance from center as the first magnet in the row.Means the inner most and opposing one is further away and the attraction forces gain the upper hand.While moving along though it moves away from the magnet row and whie still gaining force the last magnet in the row stops the cart dead center.This is the common scenario you see on the web when people try and fail.Now if you change the length of your working magnet and position in relation to the magnets in the row you can use the changes to your advantage.You can add slim disc magnets either side of your stack and observe the change in behaviour and where the cart starts to be repelled or gets stuck.In a bad case it starts fast but then stops with a big wobble back and forth.The perfect balance and size means the cart is attracted once it comes close to the magnet rows.There should only be a tiny sopt of very little repulsion right before the cart takes off.Like a hair trigger on a good gun if you know what I mean.It should then see some accelleration till about magnet 5-7 in a row of 14.From there it should level out and roll trough and keep rolling.I assume your first attempts now get you to the point where you cart start really nice, slows down a bit and seems just to miss a tiny extra push to make it out.It it shoots to the last magnet in the rows and then settles back to one or two before the end you are close!We have now two basic ways of manipulating the magnetic fields in our favour, or to "cheat" phsyics.Closing the gap.You will have realised by now that you need at least two stages for your system to be tested properly.Preferably 3 to get a 120° angle in a rotary conversion, but 5 would make sure there is hickups.This also means distance is now something to play with.Remember the pull before get at the same level with the first magnet in the rows?This is the first force we utilise by bringing the second stage at a distance CLOSE to take over the pull.Close because we don't want it to pull the cart out just like that.It would create a big "bump" and in a rotary system massive and unwanted vibrations.Instead we weaken the last magnet in either row.We still want to keep its pull but not so much the holding force that makes our cart go stuck here.Placing a magnet orientated in the same direction as your rows at the end of the row will change how and where the field of the last magnet in the row goes ;)Just to be precise: If the magnet in the row is north up and south down then the added magnet should have the poles 90° to that and in the same direction as the row.Depending how high, how close and with wich pole you place it the fields will change.You want to lower the locking force by at least 50% here - that will be suffient to overcome the holding force and gives the next stage a good chance to take over.It can also help to provide a sacrificial pole below the last magnet in the row.Again if north would be facing up then the lower magnet would also face north up but with a small distance to the upper manget.Ok, what happens here exactly?If I would want to be precise here you would need to read an awful lot, so make it simple...The lower magnet provides a way for the upper magnets south pole to get somewhere else instead of back to its original north pole.It also means there is another north pole "pushing" the north of the upper magnet more flat at the bottom half.This weakens the field strenght.Distance is key.The added magnet at the end does a similar thing.It provides attraction or repulsion forces that affect the field shape of the last magnet in the row.Imagine you have north facing towards the last magnet:You would push the last bit of the field up while also providing a very sharp end instead of a big round shape.The south pole of the last magnet also gets attracted by this added magnet, even more with one magnet below it.With those two added magnets you should be able to fully overcome the binding effect stopping your cart.It won't start and keep going when you let go of it half way down the track though, you need to start with the first magnet or give it a push to overcome the first binding effect.After that momentum takes over.If it really is that simple then where are all the successful videos about it?They are out there, you just need to look quite long for them.Most people still literally think only linear.A magnet has north and south and we can't change it - but we can...With field manipulations as above and shielding we get so much more than what physics currently dictates.Keep in mind that adding shielding under your rows of magnets will also affect how all works together ;)Some people forget this when using ferromagnetic things way too close to their testing area.Distance is also vital to keep in mind when experimenting.The closer two magnets are greater their forces to each other.You can utilise this for example by lowering magnets that seem to be far too strong in your configuration and cause a binding effect ;)And as said, shielding is nice thing for triack too - imagine what would happen with sielding on the sides of your magnet rows... ;)Make a negative into a positive!Extremly strong binding forces at a certain point in your track design can mean you might be able to utilise it instead of trying to waste it.Added magnets can divert the field to quite some extend.Shielding however can also direct them somewhere else - like in the core of a transformer where it all goes in a great circle.Even strips of shielding connecting magnets from one row to the one on the other side of the track can be utilised.Like that you turn two small magnets into one long one with twisted poles at the end.Provides more field strenght too and makes it good for areas with little to no attracting force to the cart.Then there is bigger design...Some people add a center magnet.With one on the cart and one in the center of the track you can create a cancellation field.The rows bind while the center magnet wants to push.If place where there is still enough forward momentum or even acceleration but close enough to the binding magnets it is possible to greatly lower the binding effect.But keep in mind you need to consider the added repulsion or compensated the field so it is most active towards the moving direction and less strong to where the cart is coming from.Advanced manipulations.You can machine magnets, sandpaper, file, grinder, CNC....Imagine you cut a square dice magnet from one corner to the other.Depending on how you have the field orientation you can end up several variations.But if north faced up in your dice then it will still face up in the cut pieces!Cut a pyramid and you end with a big flat south pole and a pointy north pole - and with extreme field strenth in this pointy bit.Similar story with half moon shapes.Imagine you machine a flat block magnet so you have a half moon with its pointy bits facing down and big round bit up.If north was up in the block and you shape the moon correctly then you end with two strong south pole points and a north pole that is strongest right between those points.Why is this so interesting you might wonder?Imagine you already know a magnets pole does not care if gos back to its own opposite or that of a different magnet.Then you also know you can machine and shape magnets to your will.Now imagine that for a change:Precisely machined pyramids that have the top chopped off.All tops in this example facing being the north poles and big bottom south.If you then machine a precise iron core block you make a nice cube.With magnets we need really good glue and a good press to make it happen.But if the center core is of proper size then we end with a block magnet that has a south pole on all sides.Of course to be 100% perfect we would need a zero tolerance gap but good glue and high forces can come quite close.Works as a sphere too but would even have clue where to start to machine the magnets LOL

And then I found this site. Now I'm planning on forming a hobbyist club with some of my friends (we are 16-17 years old). The problem is, I don't know with wich projects I should begin... We don't have a CNC machine or 3D printer. All suggestions are very welcome, from building a boat to a cannon to some toys to some costumes etc. If possible, please post the instructable here. Suggestions are also welcome! Thanks in advance! :p

How to wire this solar cell?

Hey there! I'm a beginner in solarbots and I just acquired a couple of paper thin solar cells that are paper thin and about 5 by 5 cm. The backside seems to be plain paper or something. I already broke one! I can't figure out how to wire or solder it, that is where the plus and minus poles are. Can someone give me a hint? Thanks! Sebar

How do I control two servo motors?

I am a beginner in this area, but been looking around on google for info on servo motors. What is the absolute simplest way to control two servo motors (for a video camera pan and tilt head), from the same unit? I don't want to go wireless (radio controlled), but instead keep it wired. Is it even possible to control pan and tilt with one single joystick? I could really need a beginners tutorial on this... Thanks for your answers!

How do I get started?

I've been looking around on here, and all i can find is Arduino stuff and stuff I don't have the money for. I'm a teenage American, I can't solder, and i don't have much wood, aluminium, or other construction supplies around to make things with, nor do i have construction skills or tools. I'm almost always without money, and I don't have a 3-Dimensional Printer / CNC machine / Hobby Club / TechShop / New-Wave Technology That's Required For This 'ible / Computer Program That Costs Lots Of Money/ Arduino or equivalent / Scrap Materials. Pretty much the only thing i could do decently is QBasic, which is hard to find inspiration for, and smashing things with a hammer. Now that I think about it, it's hard to find inspiration or a need for anything. All things considered, how do I get started making Instructables on this site, and are there any good beginner projects that use ordinary household materials or very simple beginner programming languages?

How to use LEDs for the first time?

I'm making a display case as a gift and I wanted to add a couple of LED lights with a simple switch to turn on/off.  Doesn't need to be super bright or too fancy.  The case will be about 12" long x 5" deep x 5-6" high overall.  Can anyone direct me to a good site to learn the basics of working with LEDs?  Like how to wire them up and put in the switch?  Thank you!

What is the most affordable laser cutter for a beginner?

I really would love to try out laser cutting. ..But have no idea what knowledge it requires. I want to be able to design and cut custom wooden puzzle, laser cut fabric and also to cut felt and foam. I would like to start up a small home business. Keeping in mind that I have no clue what knowledge it requires and also know that I have 4 kids and will have to have this machine in my home. I do own a silhouette cameo but unfortunately it does not cut felt or wood. It’s a fun machine for cardstock and all…but nothing heavy duty. So is it safe to have a laser cutter at home with kids?? I mean will the light or whatever that comes off the machine be harmful for my children? Also how much is the cheapest desktop version? Will it be able to cut large fabric? Can it cut 0.5” or 0.75” hard wood?? Would that be pushing my luck?? Please let me know…so I can start saving up for it. I really really love crafting….but availability of items and affordability is a big issue. Thanks!
