  • Arduino Battery Voltage Indicator

    Okay, I used to do the battery checking before and after toying. I see that you want to connect the battery voltage indicator permanently to your battery and your RC toy, but remember that the battery voltage indicator circuit will also drain your battery this way.You need these connectors :T-style connector 1 female, 2 males. (Name this connector C1) T-style connector female to JST male. (Name this connector C2)Battery plugs into C1-Male1.C1-Female plugs into RC toy.C2-Female plugs into C1-Male2.C2-Male goes to Battery Voltage Indicator Circuit.Or you don't even need the C2 connector if you want to solder the circuit directly to C1-Male, but remember to seal the connector properly to avoid short-circuit.

  • Arduino Battery Voltage Indicator

    Actually you can find the answer in comment section. Saving your time let me do it for you. I love refreshing my memories after all ^_^For 12V battery you can use voltage divider with 3 identical value resistors. So your battery voltage will be divided by 3 and as long as it is not over 15V at peak, it is safe for the arduino analog pin to read.Let's say the voltage divider circuit is now :BatteryPossitive -- R1 -- R2 -- R3 -- BatteryNegative/GNDRun a jumper wire from between R2 -- R3 to Arduino A0.Then you need to change the code from "*2" to "*3" where we calculate back to RealVoltage to be shown on LCD.Find in the code:float voltage = sensorValue * (5.00 / 1023.00) * 2;Change it with this:float voltage = sensorValue * (5.00 / 1023.00) * 3;Yes, simply change the numb…

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

    In my opinion, as long as you do not use it for extreme sports and the tracks you are running daily is not that kind of off-road tracks, that will be okay with 20 spokes.36 - 20 = 16 holes to be left-out. Just distribute them evenly and do at least 2 crosses on each spokes I think that would be okay.

    Going few years back I need to refresh my mind for a while :DWhen you see 4 or 5 crosses, you are counting with the blue spokes which are on the other side of the working-face. The same side is the red spokes. So 3 crosses is supposed to be with the red spokes, that's why on the next photo I use my palm to better viewing the crosses and blocking the other-side spokes.Yes, I should had drawn the diagram with grey-out style or dash line :D

    Still using FreeCAD with "Part Module". I haven't had enough time to focus on learning Fusion360 yet. I'm still working with simple 3D in my mind, basic shapes, chamfer, fillet, positioning, join, cut. Some apps are just too complicated to learn but nothing is impossible if we are willing to learn it. There are many text and video tutorials on the net, we just need to search for some that explain well.

    Actually there are many simple projects to make here on Instructables, but of course most of "Cool Projects" need premium tools or materials. Thingiverse is one story in a building (having room of tools, room of toys, room of gadget, etc.) while Instructables is a plaza (first floor for woodworking, second floor for 3D printing, third floor for craft, and so on...)Thingiverse is sometime like "window shopping" to me (pointing at complex builds and some that need paintings) :D

  • Arduino Battery Voltage Indicator

    I am not good at explaining math or physics but based on your formula, simple answer would be:BatteryPercantage = (2.36 - readVoltage)/0.7 * 100;realvtg = (readVoltage/2.36) * 7.4;

    "The LED on Arduino Uno board is not lighting up", do you mean the onboard LED (one the same with D13) which we set to be "light up" on low battery (below 4.1V in the code) ...or the LED telling the Arduino Uno board is not running?Are you using the same battery (3.7V) to run your Arduino? Arduino need at least 6V to power up and at least 7V to feed 5V to its I/O pins.

  • Yes, why not?24V battery can be fully charged up to 28V or more. Fully charged your battery and measure the voltage with a multimeter. If it is below 30V then you can use 6 resistors with same value for the voltage divider. If it is over 30V then pick 7.Just a little change in the code (sketch), find the line :float voltage = sensorValue * (5.00 / 1023.00) * 2;and change it to :float voltage = sensorValue * (5.00 / 1023.00) * 6;Change the multiplication to * 6 or * 7 according to the number of resistors you use on your voltage divider. We divide the voltage with resistors, then we multiply it back on the sketch, simply like that ^_^

    Not suggesting to purchase 3D printer for this tiny tool. I use 1g of filament which costs less than 1 cent and 10 minutes printing time. If someone need this they can just find any 3d printer around the neighborhood and I bet they will print one for free or give you a grin if you pay a dollar.This is the reason I purchased a 3d printer, print anything that solve my problems. I just love thinking and tinkering :)About the keychain project, it worth 10 rolls of filaments and I only used no more than 1/3 for each roll. So, the rest are now free or I can make more money from them to pay my printer off ;)

    Thank you My Friend :)116 doesn't mean anything but just saving my harddisk space by uploading them on Instructables (cloud) haha..Just enjoy thinking and tinkering :D

  • Yes it is. There was about 0.1 volt difference compared to (my) multimeter but it had stable result on several tests. Then I could simply reduce 0.1V in the code, but I left it as is. If you want higher accuracy, collect test data to count average voltage lost in the measurement and adjust the calculation in the code (like simply reduce the result with 0.1V) to get the same result with your multimeter.

  • A 3D printer. Most of the time I can imagine a shape to fix something or to make a device better or a completely new design for life hacks and a 3D printer is the only tool that can bring my imagination alive. For now, I always seek in trashes for things to be used.3D printer is getting cheaper and better so maybe I'm going to get one in early 2019 ^_^

    Ups! I didn't mention the thickness yes. My bad. I use 5 mm for bottom and top, and 8 mm for middleA 10 mm nut has 4 mm thickness, so pick any plywood that can hide it in. I am thinking of 4 layers of 4-5 mm plywood will do. You can use 2 layers for middle boards.

    As I said, my measurement changes in the making process, but the mechanism stays as is. Nut track on bottom board is cut half way down the bottom board. The nut container on middle board should fit the nut completely that means at least 4-5 mm, so that it can escape the nut track.Chopstick track is also cut half way down for both bottom board and top board. The chopstick length itself can be adjusted to fit in its track.Feel free to ask anything you want to know and I will assist at my best. Since this project is fresh in my head and fun ^_^
