Using IR Sensors to Count objects on conveyors

-

hi,
this project potato farm. have planted multiple small test plots need collect data on after harvested. need able count number of potatoes in each plot efficiently. have washer places each potato on 1 of 10 conveyor belts based on size. have ir sensor on each belt counts number of potatoes goes through belt. if possible, have way have number counted each belt sent pc (on excel sheet or tsv file or similar). looking online, seems possibly done use of arduino board, i've never used 1 , have extremely limited knowledge of them. if tell me if  possible and/or give me idea of how need done appreciated.

ah, sure, can done. ir led on 1 side, photodiode on other. moment potato passes through goes dark , that's easy count. there have been few threads counting objects in last few weeks alone.

but: have make sure have 1 potato @ time, no overlapping, space in between. otherwise they're not counted. have ensure sensors remain clean while placed next dirty potatoes - dirt on sensors , it's waiting forever huge potato pass.

a more reliable method may video camera above belt image recognition software doing counting. can handle larger volumes, harder/more expensive implement.

Flip address is out of range arduino uno r3

hello  guy, trying flash firmware on arduino uno rev3 atmega 16u2 using atmel flip. whenever try , import .hex file program, throws error " address out of range ." have looked around online , haven't found solution. , info helpful. here hex file : https://github.com/nicohood/hoodloader2/blob/master/avr/bootloaders/hexfiles/hoodloader2_0_5_uno_atmega16u2.hex its using arduino uno hid Arduino Forum > Using Arduino > Installation & Troubleshooting > Flip address is out of range arduino uno r3 arduino

Arduino DUE ADC to DAC Piezo 30 Khz-100Khz

i working on project providing echo response ultrasonic sensors. piezo facing opposite ultrasonic sensor,with foam material in between damp ultrasonic signal reflecting sensor. event based,read piezo signal[(+) --> a0,(-) --> gnd on arduino due] , after delay(5 ms) drive same piezo through dac0 [(+)---> dac0,(-)--> gnd) so ultrasonic sensor receives signal (30 khz-100 khz) after delay,thereby calculating distance after time of flight of 5 ms. int in_adc0,out_dac0;  //variables adc,dac values (adc0, dac0) void setup() {   //adc configuration   adc->adc_mr |= 0x80;   // dac in free running mode.   adc->adc_cr=2;         // starts adc conversion.   adc->adc_cher=0x80;  // enable adc channels 0     analogreadresolution(12);  analogwriteresolution(12);   //dac configuration   analogwrite(dac0,0);  // enables dac0   serial.begin(9600); }   void loop() { ...

Indesign and MathType fonts

i having trouble getting indesign recognize mathtype fonts.  have been told move mathtype fonts on 2 indesign font folder.  copied mt-extra font file mathtype folder , pasted indesign font folder.  nothing changed.  indesign still gives me blank box after copy mt-extra font mathtype -->illustrator-->indesign.   guess need instructions on how transfer of fonts done correctly.  i'v looked @ install fonts manual indesign, not clear me on how it.  need utility fontexplorer this, or there other way.  what's weird working fine until had reinstall osx , reinstall cs3, font trouble started.  need toggle "activate-reactivate' adobe cs3 , don't know how close 20 max on this, worried that.  (i suspect because of note on forum might necessary).  thoughts appreciated. i'm using windows, advice may worth nothing...   1) shouldn't have deactivate id recognize fonts. 2) design science gives fonts away in type 1 , truetype flavors....
