    Arduino roll control

    I see the ADXL sensor I used is an accelerometer, I will order an gyro so I can use both to stabilize. ( stupid fault of my) maybe possible with an extra digital compass ? I was planning on using very small control rudders

    Arduino roll control

    I see, so I need to inplant the Kalman filter in my code

    Arduino roll control

    ok here the full code: #include <SPI.h> #include <Servo.h> Servo myservo; int CS=10; int n = 90; char POWER_CTL = 0x2D; char DATA_FORMAT = 0x31; char DATAX0 = 0x32; char DATAX1 = 0x33; char DATAY0 = 0x34; char DATAY1 = 0x35; char DATAZ0 = 0x36; char DATAZ1 = 0x37; char...

    Arduino roll control

    I used an ADXL345 at the digital inputs of the arduino, I don't know anything about filtering, I just use y = map(y, -179, 179, 45, 135) ; to adjust the correction angle

    Arduino roll control

    sorry for my English, Dutch here, I meant that If I fit an camera in the rocket facing south, it will stay in that position.

    Arduino roll control

    I've just started an project to stabilize an rocket from yawing. I don't have yet the rocket designed, but I have the electronics programmed with arduino. I've seen some people used the gyro angle to steer the servo, so if the gyro hits 90 degrees, the servo does to. but if the rocket rolls...

    18.7 KJ Capacitor-bank Extreme high voltage

    Don't try this at home, an electric shock is deadly There are 52 capacitors in this bank, 250 joule each, ( 500V 2000uf ) so this capacitor bank is capable of producing 13KJ, or 18.7KJ surge 2 floors housing the capacitors floor 1 floor2 The powersupply of 2000W,

    18.7 KJ Capacitor-bank Extreme high voltage

    I think not much. this is 2000V so if I want to blow up an orange I need to place the electrodes really close inside the orange, so the resistance of the orange is not to much. if I placed those electrodes to far apart, it will only smoke, and produce some hydrogen and oxygen from the water...

    18.7 KJ Capacitor-bank Extreme high voltage

    I use 16 100Amps diodes, 4 in series 4 in parallel , they can have now 400AMP , with 3200V. those diodes are connected to the capacitor bank, and only protect the polarity of the capacitors. the same thing an diode is used for on the coil of an coilgun. the current that flows trough the diode is...

    18.7 KJ Capacitor-bank Extreme high voltage

    just tested yesterday, An Aerotech copperhead ignitor. its a small one, for their G40 motors. But I think an Orange works better :) anyway The motor will be an Cato if you try this on the field https://www.youtube.com/watch?v=tb0p9rbPQaY

    18.7 KJ Capacitor-bank Extreme high voltage

    I live at an farmer no people around . At least 10 miles from here is the first town. There are pretty much safety futures. The casing is made from 2 layer of composite material each .4" thick, Preventing that if something inside blows it won't leave the casing. The capacitors are protected...

    18.7 KJ Capacitor-bank Extreme high voltage

    what kind of switch did you used ? an thyristor ? I heard that its difficult to bunch a view thyristors together to ensure they can handle so much amps. I think the apple explodes because the water inside the apple actually changes into hydrogen and oxygen and burns at some footage you see an...

    18.7 KJ Capacitor-bank Extreme high voltage

    Hi, I build the last couple of months an capacitor bank, not real rocketry, but bad science instead. the capacitor is charged to 2000V in just 7 seconds with an 2000Watt power supply. then the energy stored in the capacitors is released in just an matter of Nanoseconds. this cause an flow of...

    thrust to weight calculator Android app

    You dont have to be an professional in computer programming There are apps, you can use exel for mobile Or download an app like rocksim for android I dont know at the time what the app is called like, But when i got home, I will look up the name of the app for you
