    Nunchaku - Skipping Rope

    Wow.. that's cool one similar to this. To make it auto retract we need kind like motor triggered by a button. You can start a new instructable for that then ;)I love to see your build :)

    Last time I rubbed too hard to remove the white spaces of paper. Now, I tweak the printout, filling the background with wood/sand color. Then I only need a light scrub to remove thin layer of paper. It is getting better and better now.

    Yes, once you own a Leatherman, its durability will stand for lifetime. They give the best 25-year guarantee.But if you have extra money, $60 Skeletool (by now) is a good deal for minimalist yet stylish.

    You can define it as long because we don't care about millisecond (decimal). You can define it in printVolt() or make it global if you want to use it outside printVolt()^_^

    Arduino Battery Voltage Indicator

    The positive post of battery (+) should go to Vin, not 5V. Two resistors are good for 9V.Thanks for the information using Proteus Simulator. I shall try it too ^_^

    If it is a standalone power source, then you should measure the voltage when it is fully charged and also when it dies (your project stop working/not working properly). The formula remain the same :OnePercent = (FullyCharged - BatteryDies) / 100;BatteryPercentage = (ReadVoltage - BatteryDies) / OnePercent;The sketch above reads the battery voltage continuously. If you want to read every 10 seconds, the simplest way is adding delay(10000); in loop section rather than complicated but more accurate timer implementation.You know about millis() then I assume you know how to write simple Arduino sketch just like me ^_^ then I can simply explain the algorithm I guess, because it needs testing phase to write working sketch and I think I don't have that time by now :DFor rough estimate remaining...

Make it global. Then add this to printVolts() function after float voltage = ... :if (PrevPercentage == 0){ // first time reading. PrevPercentage = Battery Percentage;}else if (PrevPercentage == BatteryPercentage){ // battery has not dropped, add another 10 seconds to record. TimeForOnePercent += 10; }else if (PrevPercentage - BatteryPercentage == 1.00){ // battery drops 1%, time to count the estimate remaining time. TimeForOnePercent += 10; // 10 secs has passed, we still need to add this. // EstimateRemainingTime is in second, you can convert it to hour and minute EstimateRemainingTime = Percentage * TimeForOnePercent; // Reset the PrevPercentage PrevPercentage = Battery Percentage;}Again you should recalibrate your BatteryDies time. Currently we are talking about car's battery that condidered dies at 11.9V but for other project it may die at any level depends on your project.

    Arduino Battery Voltage Indicator

    So you are going to measure your car's battery voltage. I won't say this device doesn't work but I will explain further regarding car's battery. Let's pick a normal family car or SUV which is rated 12V. It is fully charged at around 12.7V. When the engine is running you will get 13.7V - 14.7V, that is the output of the car's alternator.When your battery dies? When it reaches 11.9V, but this is not telling you about time to replace your battery. You may still charge it with external charger to working voltages, or you may not, there are a lot of possibilities regarding to car's battery such as abnormal discharging.The range of working voltage of a car battery is 11.9V to 12.7V, so you can calculate it like this :100% = 12.7 - 11.9 = 0.8V1% = 0.8 / 100 = 0.008VBattery percentage = (ReadVo...

Starting up a car needs a lot of amp, not voltage. Checking on the voltage regularly can give you a rough condition of your car's battery and help you in diagnosing a battery problem like if something in the car is discharging your battery when the engine is off.In certain case you can jump start your car and let it run for 20 mins to charge the battery and if the battery is still good (it can store charges) then no replacement is needed. Someone may have leave the key in ACC and every electronic in the car is discharging the battery. That happens to old car. New family car will warn you with "beeps" when your your key is plugged, the engine is off and the driver's door is open (meaning the driver is leaving the car without the key).

    Arduino Battery Voltage Indicator

    This project do the same purpose to me. I wanted to know if my battery can run my RC toy should I charge it before playing.Let us say my RC needs at least 6V to run its Arduino and motors and every modules in it. I am using a 7.4V battery that is fully charged to 8.4V. Do some math here :8.4 - 6 = 2.4 (this is 100%)2.4 / 100 = 0.024 (this is 1%)then we can set in the code :BatteryLife = 100 - ((8.4 - voltage ) / 2.4 * 100)Now you got your BatteryLife in percentage before your device stop working.

    All you need is a DC-DC voltage step down module that cost $1 or less. Try to set it up as the picture below. Now your Arduino is powered by the same battery but with acceptable voltage.If your battery is fully charged at around 18 volts then A0 will read 4.5 volts. You change the code :float voltage = sensorValue * (5.00 / 1023.00) * 2;to float voltage = sensorValue * (5.00 / 1023.00) * 4;because you have divided the voltage into four equals-- that is 4.5V read by your Arduino through A0 pin, then you need to calculate back to get the real voltage that is 18V.

    Do not feed 15V to your Arduino Vin. Arduino can only take up to 12V and its I/O pin can only take up to 5V.Use a voltage regulator for your Arduino (convert your 15V to 5V) and use voltage divider (4 resistors needed because your 15V could be fully charged up to 18V) before A0 pin because we need to read the real voltage.

So I won't put so many favorites in the list or it will be hard to find one.The comment. Mostly people with the same interests will comment, or people having trouble in following the instruction will ask. Growing followers needs time. Keep learning and writing good instructables will make it happen. You can join classes to expand your skill in other topics. Step 5 : share your work on social media will increase your views and maybe followers and comments.The view. The more the better. It means people read your instructables. Either only the introduction or the whole steps, they like it or not, it doesn't matter. Some people will find it useful, unique, awesome, and if they run a website somewhere out there, they might share your instructables on their sites or Pinterest or somewhere else. Believe me. You will notice this kind of thing happens when you search your "title" at Google and see that some DIY sites are sharing your instructables.Keep making, keep sharing, believe me there are a lot of Moms out there just about following you -- the winner with three trophies by now. ;)Don't worry about the views, comments, or faves. Keep collecting the complete colors of Robot tee shirt :D

    Thank you, Sir for your input. Surely iTeam need help from good Authors to help narrowing the finalists. As I said I am not an insider as well and I wrote this Instructables simply to deliver rough guidelines and also alternative ways to win prizes from Instructables apart from contests. Also to encourage dissappointed Authors who have written good instructables but felt like there're conspiracies because they didn't win any contest.

Don't worry, they are working on (or maybe they already have) another way to reward Authors, so just keep writing and sharing your ideas with us. Maybe on your 25th featured instructables or on your tenth Homepage Featured Instructables that they will send you something?

"I love the way you cut that hole." I used to cut a hole that way, now I know that is a special way unlike others. "Do I have any other unique-ways to share?" That question will make us think and write another instructable ^^ There are many members in iTeam covering a wide area of DIYs, er.. I mean all kind of DIY projects. That means whatever the topic of our projects, someone in the team must have the same interest. Then we analyze his/her instructables and comments to produce good write-up for ourselves."Unique", yes, either products or ways, why that word didn't cross my mind in the process of writing this instructable? English is not my mother's tongue and Google is my best friend, teaches me vocabulary and grammar.So sad to hear that four-featured-instructables has been dismissed. Yes, that is understandably that we now have so many authors and many instructables to read by limited iTeam. Can't wait to figure out the new way of rewarding ^^Ahh.. Draft-ing is just crossing my mind. Technically (I am a technical Guy indeed) it will increase your chance to win. As soon as a contest starts, early birds get more votes. Some would say your instructable will be buried down by time, but with great partnership with Step #5 : Social Media, you can re-share your work once a week. People will get there with a single click without digging the Instructables pages. As I mentioned before, I am not a real bounty hunter myself. I do use "draft" as notepad and sticky note sometimes, but not collecting projects to be published on certain time joining contests. Instead, I use contest themes to spin my brain, to think what can I make in my spare time :D"2 drafts" you saw on the screenshot, one was this How to Win Prizes at Instructables, the other has stayed there for years, the Bose Box contest which I cannot delete even with the old editor. I just can't hold myself from clicking the orange "Publish" button soon I finished my writing :D

    People with large social media presence may have advantages and may not. When their friends join Instructables to vote, they may see other cool projects and vote for them as well, that's fair :)Actually I wan't to post this in Community Topic, but thinking that people are likely flipping the front pages of Instructables only, and seldom do they go the Community Section, I decided to put it as an instructable post. So that they know about Upcoming Contests, The Clinic, Featuring Guidelines, and most of all, they cancelled their leaving Instructables ^^

    Oil/Fuel Filter Opener

    Yes, don't spend too much for seldom use tool. We have heavy trucks and light trucks here and we use it more often but in my case those truck drivers just can't be gentle to my tool. Why should I spend much money on that tool for them to break while I can make my own free tool? ;)Bicycle chain is perfect if you are going to make one. That large chain from motorcycle was what I had in hand at that time. Now we have three DIY chain-wrenches with different sizes laying on the shelves.

    Sure it is, but we pay much more for the shipment than the jig itself :DI also made my own pegboard but I'm not a perfectionist and I can live with that :D

  • Lacing Bike Wheel : 36 Holes Hub to 32 Holes Rim

    6 weeks ago, sorry I missed your question for so long.Last year I was building my bike, and that was my first to be honest. Searching on the net put me in the same condition like you "will/will not work".This is my advice, if you can get a proper hub (48 holes) to your larger rims, go get it. If you can't because of budget problem or you just can't find that 48H-hub, then start constructing your wheel, you might need different size of spokes or you can try different style of lacing combination :)I can't help you further than tis because I don't own the 36H-hub and 48H-rim.

    In my case, it turned out to be four (likely, it's been a year) too-long spokes but since I have double wall rims, everything goes well, those too-long spokes won't stab into my inner tube. Buy more spokes at different length instead of rim for cheaper option ^^Here I don't have the option to "buy more spokes" because they are selling standard size of spokes only.My wheels are good until today ;)

    Build a Skateboard From Scrap Acrylic

    Well, just like the author said, all skateboards scratch.PMMA does resistant to scratches, but we are talking about jump and smash and grind. I am no player, just fan. Author took my previous comment as pride and not complaint. This is an amazing piece of art, truly, and he got my vote ;)

    No-Weld Spark Plug Aeroplane

    The simplest project ever. I made two of this for my sons using popsicle sticks because metal will be hard to shape. I also add propellers stabbed into the center electrode. Technically they are spinnable but stuck at the side electrode :D

    Acrylic? You gotta be kidding. It will scratch badly. I think it will stay in your living room or bed room. You get my vote ;)

    Unfortunately I am far away from US or UK. But there must be a way out to pay the shipment :DThanks for the link anyway ;)

    Wonderful. Hope to see this jig sold in the market, because I don't have 3D printer (T-T)

    Arduino Battery Voltage Indicator

    It is better to power up your Arduino with a separate power supply. If you use the same battery to power your Arduino, make sure you have a voltage regulator circuit to step down the voltage to 9V, because 12V battery may be fully charged to some kind of 14V. About high current normally Arduino will draw only as much as needed, but it is better to put a fuse in case of short-circuit. Technically, following this instructable by using 3 pieces of 10K resistors and a little change in the code (*2 to *3) are all you need.

    Arduino Battery Voltage Indicator

    Technically you can use 10 x 10K resistors to divide the voltage. But, looking at your high current battery which may harm your Arduino, it is best to take another option. There are high current (30A) digital voltmeter and ammeter in markets. You just need to pick one and learn how to connect it to arduino+gsm shield if you say you want to send message to your phone when the battery is low.

    Sorry for a very late reply. For 12V battery you can use 3 identical value resistors. Let's say 3 x 10K resistors. Simply change this code: float voltage = sensorValue * (5.00 / 1023.00) * 2;To this one: float voltage = sensorValue * (5.00 / 1023.00) * 3;Regarding to .csv file, I have never worked with SD card module but you can take a look at this topic : https://forum.arduino.cc/index.php?topic=447602.0

    The magnetic extension is not deep enough for standard bits in the market. When you put the phillips bit in, it won't catch the hex of the bit, unless you shorten it. Easy for slotted bit but not for phillips head :D
