Hello everyone, I just won a prize for the instructables ornament and I was filling the details form. Then, I read one statement which stated that if I live outside US then I will receive a coupon of the prize value. I am not a fan of money but a fan of Instructables. So, at last I want to say that I would like to get the instructables prize pack instead of a $10 coupon. If you will send the pack, it will remain with me forever but the movey will get spent Thanks

Curious, Monday or Tuesday of this last week I found an Instructable for a Switched Mode Variable Power Supply I found very interesting. I didn’t print the design out because I wasn’t sure how I was fixed for parts. I went back the next day and the Instructable was gone. All I get is; “404: We're sorry, things break sometimes” I really don’t have any other description other than it was built in a metal enclosure, blue, and used 2 V/A meters. Without the Instructable I can’t even tell you who made the Instructable. Has anyone seen and/or has the plans for this Instructables? The only thing I can add is a picture I've added from the internet.Any help would be greatly appreciated. Thanks, Dennis

Okay, I have a DSi since 2010 (I don't remember when I bought it, so this could be false. Look, it's old. OK?) And it's been working fine untill one day. I turned it on, and the power light (blue in this case) turned on for a milisecond and then turned off. I tried it multiple times but nope. Plugging in the charger makes the charging light blink non-stop. So I tried opening up the DSi (I opended it up mutliple times before so the warranty is voided already. I also did it correctly the other times so opening it isn't the problem here) to find out what is wrong but I found nothing wrong in it! Sure, the ribbon cable connecting to the SD card is broken but it's been like that for years if I remember correctly. Battery was looking allright, took it out with a voltmeter, wasn't dead (Also, I doubt it static electricity because it wouldn't do ANYTHING). So, I closed it up and opended up the charger. Strangely enough, a piece of the charger's motherboard was cut off! Like someone took a bite! But how could I be using that charger for all this time and it was working. I won't use it again, defenitely. So I went to a store to try out the store's charger, it gets weirder. I plugged it in and the charging light flickered like before BUT, for only a couple of seconds. Anyway, I went home and couldn't figure it out what it is. Only thing I imagine is the charge port (the port where you put the cable to charge it, duh). I'm sorry if you cannot see the pictures very clear but my camera doesn't focus very well, and I'm not a profesional photographer to set the focus etc. So I'm writing now. Please help! Thanks

I just want to make a backlit box with a logo on it. I'm looking for the backlighting to be green. Every single video or tutorial I find on Analog LED strips jumps straight into using a controller or an Arduino. Can I not just use a power supply? Can I use resistors or something of the like to send x amount of power to r, g, or b for the color I want? Is there not just a simple LED strip guide out there?

Hello guys,I am planning to do one project where I need to use mechanical timer - or better said mechanism. It needs to run for 60 minutes and it does not need to be really precise. So +/- 5 minutes is not a problem. Now... the main "problem" bothering me is the size of this mechanism. Maximum diameter of the mechanism should be under 3.5cm and maximum thickness can be 2.5cm.. This is why I can not use mechanical mechanism from kitchen timer. Because it is too big. (diameter of around 5.5cm or even more).. I have been thinking of mechanism from wind up toys since it is really small.. Is there any way to modify it? Does anybody have experience with this? I have been thinking also of using damper and spring... The other requirement is that it needs to be cheap (which means under 5$), that is why I can not use mechanism from watches. Basically what I would need is the same mechanism you can get in kitchen timer, but it needs to be smaller. Now I do not care with which technique or mechanism we achieve this. It just need to run for 60 minutes and it needs to be mechanical. Can anybody please help me with suggestions on how to make this work? Thank you everybody in advance!Best Regards, Luke

Hi all, Firstly two things; 1) I just wanted to say thank you so much to all of the guys on this answers section, for giving a lot of their time whilst being incredibly helpful, patient and overall just awesome! Just to name a few of the most consistently helpful; steveastrouk, Kiteman, iceng and Downunder35m. 2) I know this question has been asked before and asking it again has been my last resort after trawling the web as I know reviving old topics can irritate the OP etc.. But anyway: I am building another PC, with the challenge of it being a portable 'console killer'. The idea is to make a Mini ITX gaming PC as small as possible (a challenge in itself) which can run for an hour or two on battery and then needing to be plugged in and recharged whilst still being usable. The current specs; Asus H81I-PLUS Intel H81 DDR3 Mini ITX Motherboard (1150 Socket) Intel i5 3.2Ghz Processor Zotac Nvidia GeForce GTX 750 Ti 2GB GPU CPU Liquid Cooler Corsair Hydro H55 120mm Fan So I need all of this... ...battery powered... So I was thinking; all a PSU is is an AC adapter and step down transformer. So all I would need is several laptop batteries (and a way of charging them seperately) , a way of mounting them, a voltage regulator and wiring to power the computer and bypass the battery AND charge it when I am using a laptop external PSU. Right? But then, is the high current from a wall socket necessary to a PC's function? Thanks!

Hi all, I have an idea for an Arduino based instrument cluster for my cafe racer (1980 xs400). My question is what kind of rotary encoder I should use to measure the rotation from the cables coming from the engine block and front wheel that went to the original cluster (shown in pictures). I want something that won't break at higher RPMs and is more or less water proof. I have an idea of how to code this on the software level as well, but I'm not to experienced with C/C++ so any help there would also be appreciated. The end goal for this part of the cluster is to output the RPM and MPH to respective WS2812B 5050 LED strips, and possibly a small oLED later down the line. If something could be made more clear on this post let me know and I'll try to elaborate. Thanks again

Go back just 20 years and on a busy shopping street you saw the poeple walking around as they do today - or did they?I remember poeple talking to each other, standing in front of the shop windows and checking the offers.People greeting each other or stopping for a chat.Now all you see it zombies staring at their phone screen or texting.Even the dreaded "self talker" with a BT earpiece seems to die out.You like fast food don't you? ;)But did you ever bother to waste some time watching people going through the drive through?Back in the days they mostly tried to keep their cigarette going or the girls were busy with the make up.Today it is almost impossibe to spot someone making it through a drive through without playing on his or her phone.The shopping is finnished and all you want is to pay once your trolley was emptied onto the conveyor going to the register.If it were not for the person in front of you...On hand holds the phone to the ear, you hear the latest gossip you don't want to know anything about...And then painfully slow one hand tries to load the trolley again and then finally tries to find a credit with still some money left on it.My favourite are however all those people who are fully addicted to their phone and go mental if you try to tell them.You are having a cold beer with your mate and just want to reflect about the great day fishing.Hold on a second....Oh, did you see this today? ....Ok, just quickly checking FB...Your beer is already number three while your mates beer went warm and stale.Fair enough, was a long day...Then you knock at his door at 3AM to take the boat or or go on a trip.Still half asleep but the phone and all social media must be checked before even making it to the toilet...You get the picture, hopefully not by looking in a mirror now ;)When the "internet" started to be a thing I was already long on the wagon of "online".And back then some big players in the game said "One day we will all be connected in real time!".Of course everyone had a good laugh and moved on.No chance "everyone" could afford a computer, let alone get the skills to go "online".But look at today:You call your provider, tell them you need internet at home and you just plug a box in and have it.Oh, moible is prefered?No problem, just pick the phone you fancy, add a sim card and off you go minutes later.I remember libraries not just as a place to read books but also as a place to learn new things.Explore the world, see other cultures...If you could afford it you might have seen it all for yourself and in real.Today all this is replaced by a single term:"Google it!"What we have today is a simple money scheme created through the totally useless "need" to be connected.So how do you know that you are already addicted to you electronic friend and failed to realise it?Quite simple actually and in the same way as maybe your grandparents did with your parents - if they are old enough ;)Yes I mean the goggle box, the good old TV.Back in the day we said that 4 hours of TV time for a teen is already quite much.We can't escape screens for work or school needs anymore.What we can though is ask:How many hours per day do you spend on yo phone? The time that is not work or school related...How much of your daily life do you organise through your phone by texting, social media or just notes, reminders and so on?Do you complain that even the newest phone newer has enough charge for your "needs"? ;)Do you get cramps in your hands or fingers? ;)Or just plain simple: How long could you really be totally without mobile phone, computer and internet?The answers you give yourself might shock you ;)What are your thoughts on the mobile phone zombies of today?

I just bought a "custom crucible furnace" from a local university's surplus department and I have absolutely no idea how to get it working. It is roughly 4 feet in diameter and 4 1/2 feet tall, it has 6 'coils' of metal attached in series with thick ribbon-y cable at the top. The side has a 'band' that sticks out but as far as I can tell it is hollow.From what I can tell it might be an arc furnace that something blew up in and damaged a bunch of the components. I really want to get it working as I've been saving aluminum cans for a long time and scrap metal so my plan now is to just hook up the cables to my arc welder and see what happens :) but if anyone knows anything about it or where I can go to get more info that would be much appreciated!

Consider this: is an individual person better of with emotion, or with pure logic and a strict moral code? I mean, lots and lots of bad things in the world originate from emotion. People hurt others because they are angry, or because they are sad and want to feel better, or sometimes even for pleasure. Others' are moderately to seriously impeded by fear ( like phobia), by guilt, depression, anger; revenge and pleasure (STD's, for example). Do the positive sides outweigh those? And before you answer, think this: people say sociopaths and psychopaths are emotionless, and therefore kill. but those merely suffer a lack of empathy and concience, and do bad stuff to satisfy their pleasure. Because, is there any logical reason to hurt or kill another human? And think about the Star Trek: The Next Generation character "Data" (if you know him). Emotionless, but the last person (or android, for that matter) in the galaxy to hurt another person without reason.

I bought a small brush-less motor that was designed as a motor for a small RC plane. I tested it by spinning it with a drill. I was surprised to find that the motor did not generate much in the way of voltage. Why not? It's too bad - many small brush-less motors are so nice. No brushes, ball bearings, and low cost. I would have thought that forcing a brush-less motor to spin would have generated power. Thanks for any insight.
