Wanted Arduino Advice For Teenager

My son has expressed an interest in Arduino because he's in an after school group of "builders" in which a number of students are toying with Raspberry Pi. He was told that Arduino can be built using a ChromeBook - we don't own a Windows computer (only Macs). He believes that he could build using YouTube and other computer based research. Can someone tell me if Arduino is compatible with ChromeBook? With so many kits available, can you please advise one that will engage him for multiple projects and may even be used for growth but at the same time is not going to break the bank? Any advice is much appreciated!!

Best motor and switch for this swinging arm?

I am trying to make the following: i need a 4 foot arm to swing parallel to the ground at a fulcrum. Only needs to travel 90 degrees one direction, then back 90 degrees to its original spot - Kind of like 1 windshield wiper running parallel to the ground the weight of the arm plus load at the end is roughly 10pounds this would be triggered by a single button thats the gist of it. Now if. I could tweak it... i would like one press of button A to move the arm 90 degrees then it stops. A second press of button A would move the arm back to where it originally was.  Or, if this is too costly, I could hold the button down while the arm cycles 90 degrees and back, releasing the switch when the arm reaches its desired location I need cheap options or at least a good place to start. I have zero coding or electronics knowledge thank you

how to use LDR as a relay for RC car to increase voltage to motor

Hi there,  I would like to know more about how LDR's work, its quite difficult to source 3 volt relays in South Africa, so I had an Epiphany, why not use 2x  LDR 1x for Forward and 1x for Reverse on an RC car, I don't know much about how responsive the solution is, how many seconds or milliseconds delay  there is? Does it work like a switch?  would it be a viable option on an RC car? I'm sure this could apply to little 3 volt RC cars upwards, I know brushless is the way to go, however this would indeed be a great learning experience.  kindest Regards, Lee Reddy.

Momentary flashing lights

What is the easiest/simplest method of making a flashing light (preferably a small string of LED's or a piece of EL tape) connected to a momentary push switch? no timer or any other complication just lights that will flash on and off until the button is released. i want to make a flashing indicator light and switch small enough to mount on a ring that i can wear on my pointing finger so that the button hits the back of my hand as i straighten my finger to point and the light flashes only until i curl my finger to release the switch.

bike booster kit

There is a project here on how to build a "BIKE BOOSTER KIT". The kit is made up of multiple 3d printed parts, including the battery pack, charger, test equipment, and a choice of small or large rc notor. The built kit is designed to mount above the front tire either bike or trike. Although I do not know what kind of bracket is included for mounting. It can be configured to fit in a bike frame in any number of positions as long as the roller can touch the front tire. I plan to mount this on a trike, There are only two possible locations, on the handlebar stem, or the fork center hole for the fender after fender has been removed. I need mounting instructions, user manual, premium hardware kit, any special mounting brackets, and sources as to where I can buy a fully assembled kit charged and ready for mounting. I am concerned that the unit is not long enough to reach the tire from the stem. I might need some sort of extender block to make it longer. Complete advice please. reeltoreelguy@gmail.com.  photo included.

Five to ten 10MM LED require what power supply?

I am planning on making a LED reading light for my nephew, but I'm not sure what kind of power supply would be needed, or how long it would last. I have bought plenty of 10mm LED's and I'm planning on using one or two per light points, with there being five light points in an 8x11 inch space. What kind of power supply would I need for these? I was thinking of going with AA batteries, since they're readily available, but I'm not sure if I'd need one or four (put into one of those cheap battery holders, I think they're setup in series.) Also, is there a way to do it without resisters, or would resisters be required, no matter what? Thanks for any assistance! The Atomic Soul

Tips for Making Instructables Easier, Faster, & Better

*Typing...* It took me about a week to make my Instructable on my magnetic pegboard, and about a month to make my I'ble on SpectrumLED. Now I don't even want to know how much time it took chr to make his 8X8X8 LED Cube Instructable... 2 Weeks ago, I published an Instructable on my Articulating Lamp, I don't think it took me more than 3-4 hours... Other than the fact that I now have way more experience, I've thought of several tips that decrease the amount of time I have to sit in front of  the computer and type, by a HUGE amount. If making and I'ble is a lot of work, it'll feel like work, and I'll need to take a break... If it's fairly easy, I'll want to make more! I will leave some of the tips that I've come up with in the comments. If you have your own leave them in the comments below!

Why?: Contest, Finalists, OAE, and... WHAT?

EDIT: This has turned out to be a really long post. Please see the top comment if you don't want to read everything, or if you aren't a scanner (seriously...). I did my best to stop my longforumtopicisitis disease... I don't really know how to write this "topic". I know I'm not the only one that's a bit upset about it. I'll do my best to keep it short, but if you might get pretty confused if you don't read (almost) everything. I would really like to hear your 100% HONEST opinion. I am looking for criticism. Don't worry if your response sounds harsh. Thank you. ------------------------------------------------------------------------ Instructables member OAE has posted several forum topics about contest winners in the past months. I understand the fact that he is annoyed some Instructables that win in contests aren't original, aren't documented very well, and lack pictures. It does bug me a bit when these types of Instructables win, but I guess that there's normally a reason for that, since most contests don't lack entries... He also mentioned the fact that he was pretty annoyed about the fact that he doesn't win. I DO NOT want to insult him in any way, but even though his Instructables are fairly well documented, I wouldn't expect for one of his Instructables to be a finalist. Brooklyntonia wrote that "A paper airplane on a cutting mat doesn't scream click and vote.", and I agree. However, I seem to have the same (I think) problem with my Instructables, and I think that it has  just gotten a bit too much. I've won in 3 contest with 86 I'bles (think of that as 50, if you know what I mean...), which is why I feel a bit weird for "complaining". It's not that I publish Instructables just for winning in contests. Far from that. SOOOOOOOO MANY times in the past year, I have posted an Instructable that I was absolutely positive that would win in a contest, but it wasn't even a runner up! I have SO MANY! It would take me an hour to post half of them, but here are some: Articulating 70W Spectrum-Balanced LED Panel for the Lamps & Lighting Contest How to Make a Wooden 6" Bench-Vise for the Wood Contest The Flat-Pack Bandsaw for the Flat-Pack Contest (less than the others, though...) How to Build a Wooden Drill-Press Vise for the Hand-tools Only Contest 9 Unusual Tool Storage Methods for Your Workshop for the Living without Closets Contest Make Your Own Plywood Mallet! for the Plywood Contest World's Most Over-Engineered 14-in-1 Soldering Station! for the Leftovers Contest Please correct me if I'm wrong: These Instructable are featured, well documented, meet the contests requirements, contain well lit high quality photos, are original (90%, of course...). I "politely encourage" people to vote only in an Instructable that I think will win... I would understand not winning at all once or twice, but not even being a runner up even once? WHAT am I doing SO HORRIBLY WRONG? What discourages me even more is that even though I want to build something that I really need, I will wait for months until a contest opens, start making, spend a ton of time on the Instructable, and then I realise that I waited for so long, and my I'ble hasn't even won! Benne, however, even though we both publish somehow similar content, has mastered this somehow! If I make something, I have to type up the Instructable immediately, because my short term memory is pretty bad. I wrote about this a bit here. If I calm the excitement down, I might be able not to publish it right away, but that will just discourage me, since I will feel that I haven't accomplished anything (aka positive feedback, etc...). Then after waiting several months, I will publish the I'ble and still not win? Imagine your boss, at work, saying "Okay (your name), you've spent 10 hours working, but I'm going to pay you only next year. Oh, nevermind, we're having budget cuts. I'm not going to pay you at all" Wait, WHAT? WHY? I'm making this sound as if it's a bet, which is okay since you don't get "paid" from Instructables, but never getting anything at all is annoying. Also, publishing Instructables is not extremely addicting (A REAL one... ;)  I think I am following the contest guidelines, but not winning again, and again... Why? Is there something that I don't know? Thank you for reading!

A Challenge: DIY gravity lamp

I have decided to power the lighting in my house with gravity alone starting next year. The idea started here: Greener Gadgets: Gravity LampI have some ideas about how to make it possible using some existing instructables and I though I would share this to get people thinking about new ways to use gravity as a power source. Think about it, gravity is clean, constant, eternal and EVERYWHERE. I think that this instructable has some of the essential components: Cordless Drill Crank Charge BatteriesIt gives a basic example of kinetic energy being converted into electricity, but for this application the kinetic energy will be supplied by gravity instead of the hand crank. The real fun with this project, I think, is the different ways that the kinetic energy of the weight can be harnessed. The screw used by the Gravity Lamp is just one method. A weight on a rope that is wrapped around a spool or crank is another option or even something based on the mechanism of a grandfather clock. One could even imagine a single massive weight that the whole family would hoist, with the help of pulleys, every evening to power their home lighting. Who knows.....It's time to start a gravity revolution.

DC Motor Stop and reverse for a feeder

Hi, I attempting to design a feeder that will raise and lower an access door to where the feed is at. The door will open at dawn and close at dusk. I am trying to design a setup similar to an automatic car antenna. When enough light hits the photocell, the motor engages, travels a distance or hits resistance and stops. When light is no longer strong enough, the motor engages in the opposite direction and after the same distance or it meets resistance, stops again. Is this possible to do without Arduino as I am trying to keep this cheap? If so, what do I need and how can this be accomplished? The photocell is not a requirement as I have seen astro timers that can adjust for the changing sunset and sunrise times. Please help.

Does time of the entry matter?

Hi, Please note this is not a complain or anything of a sort but rather just a wondering, a question. I am not a total newbie here but I am also not much of an active user.  I am a busy leatherworker with no spare time for almost anything. I do love writing tutorials and helping others who want to know more about working with leather. When I write a tutorial I put my time and effort to make it really good so a person who follows it have almost none questions left. It does take a huge amount of time which usually leads to the fact that I enter a contest at the very last day/moment.   And here comes my question. Since the voting is open from the start of the contest don't those who entered in the beginning have more benefits/chances to win simply because they have entered early and so have more views/votes? I know there are those three days still open for voting after a contest is closed but this is a too short period comparing to the month or even more time available to the early birds. How does the entry time affect the selection of the finalists which from what I understand is based purely on viewers' voting? Do judges take into consideration the fact that the entry was at the last minute so could not get too many votes for the very same reason? Thank you! Era

Homemade electric nail file

Hey there to all you wonderful people! I have an odd proposal / suggestion / idea... I was wondering if anyone had ever considered this as an Instructables project by any (small) chance? Don't laugh TOO much, this is not something that would be considered a run-of-the-mill every-day kind of DIY by any means... Here's my ish: I'm not incredibly fantastic when it comes to personal grooming, doing the basics as quickly as possible so as to waste as little time getting ready for the day. However, me tooties are a point of some concern due to an out-of-the-ordinary dermal condition. As a result of this, I have to take special attention to moisturizing feet and toenail filing. Also, I suffered an accident when I was much younger that caused the nails on the big toe to grow skew. Long story short I've now been sitting on the floor for 40 minutes with a manual file and, while my one's and two's a looking smashing, I thought there MUST be a way of making my own electric nail file. I thought to try and convert a screwdriver bit for my electric screwdriver into a spherical file which I'm sure would literally save me HOURS and will do my knees a world of good - I've found myself kneeling in 1 position for a lot longer than nature intended. I am NOT the shining Instructables Star in the making by ANY stretch of the imagination but I do have some interesting theories about time travel (not really applicable here, but I wanted to try and sound less daaa - cos this isn't a 'Change The World' kinda project) In any event, I thought maybe someone who has a grasp of my concept and an understanding of how things worked may have a thought on how to accomplish this? Baring in mind that where I live, things like electric nail files are luxuries available only to a specific  social group & not an option for the general norm pavements specials such as I... I'm so interested to see if anyone could give me some help. You'd LITERALLY be saving my life (or at least adding about 10 - 15 years to it where I don't have to spend crouched over a small chair for a quarter of my day every 5 or 6 days) Stopped giggling yet? :) Tx guys, it's a dumb thing to ask, but this dumb thing has the potential to SIGNIFICANTLY change my life in a very practical way. Kind Regards and Loads of thanks! ps It ses to add images, but I think just for the sake of global sanity I'll refrain until I've found a working solution (or a pic of someone else's feet) :) Much love t'ya!

Are you looking for the world's worst picture? Look at my profile picture! (As of now...) Since I've opened a new YT Channel, I decided that I'd make myself a channel intro (which I've already done) and nice banner, and most importantly: INSTRUCTABLIZE IT! (It would also be nice to have an option for a banner here on Instructables, since there is a lot of wasted space with the new update..) After a few hours*, I think I've finally come up with a nice one- See the screenshot below, if you're interested. (EDIT: Here is a link to may channel, in case I update it in the future, or if you'd like to give me some feedback-- I'd really appreciate that! :) It's not perfect, but I like it. I like how my name is in fairly bright green, the 24 is in blue. I also like how the robots hover all over the place, though I think I might have made them a bit too big... I made this with the Pixlr Editor, and if you want to make your own, feel free to use my image and modify it. If you do this too, don't forget to post a picture/ link to your channel below! EDIT: I forgot to write this, but this was actually my "second" try, since I tried to do something similar to this a few days ago... It is now a pinned (to the top) tweet on My Twitter (as of now, too...).  *This might look really simple, but it took me several hours to do this. Don't ask why!
