How would i implement position and heading readings into my SLAM robot?

i have posted question on stack exchange yesterday haven't gotten response yet i'm trying luck here. i trying build low-cost slam system mpu-6050 , gy-271 (magnetometer). currently, have robot arduino collects sensor data , raspberry pi (hopefully) slam calculations. i want robot able use 3 sensor readings (along pml) in slam create 2d map of environment. however, considering want 2d map, not require axis readings correct? i read post 1 of answers said yaw gyroscope, , x , y accelerometer needed. 1. question is, how implement slam robot? complementary filter work?? 2. need use axis (x, y, , z) readings magnetometer? or 1 or 2 axis? here code if want have @ it. code: [select] #include <wire.h> long accelx, accely, accelz; float gforcex, gforcey, gforcez; long gyrox, gyroy, gyroz; float rotx, roty, rotz; long magx, magy, magz; void setup() {   serial.begin(9600);   wire.begin();   setupmpu();   //  //find starting angle.   //  acc...

Sensor de presion dif mpx10dp + amplificador

buenas tardes, como estan? soy nuevo por aca. me encuentro realizando un proyecto en donde necesito medir la diferncia de presion entre dos puntos que difieren en unos pocos pascales. para realizarlo compre un sensor de presion diferencial mpx10dp. por ser inexperto en el tema, no me di cuenta del rango de alimentación del sensor, e investigando un poco leí que tenego que usar una etapa amplificadora para trabajar con esa precision. en este punto esta mi problema. segun leí precisaría un amplificador de instrumentación, que con uno modelo ad620 podría armarlo. no estoy seguro al respecto y quería saber si alguno podría darme una mano en el armado de este circuito de amplificación y como realizarlo. adjunto el datasheet del sensor y del posible amplificador. muchismas gracias, saludos!! si, estas en lo correcto y el ad620 esta entre tus mejores opciones. para la próximoa compra un mpx5010dp que tiene salida 0.5 4.5vdc Ardui...

time more specific. my actual code on 2000 lines of object-oriented goodness, i'll give simplified version of i'm doing. code: [select] uint64_t accumulator; //the question: should use large integer this, or can use float/double? uint32_t numsamples; float actualvalue; void accumulatevalues() { accumulator += readtcvalue()*1000; //this value floating-point, multiply 1000 keep 3 decimal places. numsamples++ } void applyvalues() { actualvalue = accumulator / numsamples / 1000; //divide 1000 out multiplied earlier numsamples = 0; accumulator = 0; } void loop() { currenttime = millis(); while (millis() - currenttime < 10000) // loops fast can until 10s has passed { accumulatevalues(); //accumulates sensor value samples } applyvalues(); //grabs average of said samples , resets accumulator , sample counter serial.println(actualvalue); } so right accumulate values integer value. i'm wondering if float/double able work in scenario. way, don...

Flashing more than 128kb into an Atmega2560 MCU...what programmer?

hi, recently read problems flash more 128kb atmega2560, due to change 2 bit counter (up 128kb) 3 bit counter (from 128kb onwards til 256kb). i think manpage of avrdude says:  atmega2560, atmega2561                                flash addressing above 128 kb not supported programming                                hardware.  known work jtag2, stk500v2, , bit-bang pro‐                                grammers. the genuine atmel/microchip hardware "feels" little expensive...jtag complicated (and expensive) ... , counts "bitbanging programmer"... i know bitbanging (i think), using gpios bitbanging spi instead hardware spi reason, why more 128kb can programmed? normally use simple ftdi-cable , bootloader flash stuff ...

howto install template overrides? - Joomla! Forum - community, help and support

how can add template overrides? in local template directory have created folders html->com_content->category files blog.php blog_item.php default.php etc.. but when install template there isn't folder html on server images, css, js , other use do have add template overrides templatedetail.xml? if whanna upload them folder error "no permission create directory" can change permission every folder accept folders??? setting in joomla ? solved problem: i've uninstalled template , manually uploaded template works Board index Joomla!

Step Up Module got fried

hi today fried 2 off step modules (like one: http://bit.ly/2vh4dxo). tried boost 12v 24v power mini humidifier. current flows close maximum limit, although worked 12v pb battery (was 12.50v). thought work 12v psu. couldn't keep 24v , made high hum noise. after 10 seconds chip on step module went in smoke , fire. mosfet (irf540n) got hot. after thought it  faulty module , connected step module directly 12v power source. 1 went ip in flames faster. i'm curious reason why module works on 12v battery, not on 12v psu. maybe of guess why happened. thank help. more details: psu rated @ 12v @10a battery ~12.5v humidifier works fine on 24v power source , uses 0.6a. rated ac , dc. mosfet stays cool. step modules have input current limit , may not exceed. consult chip data sheet. to produce 24v @ 0.6a requires 12v @ more 1.2 a, taking account conversion efficiency.
