Powering a 12v Solenoid with a small battery.

-

i working on project requires powering 12v solenoid battery (https://www.elecrow.com/electromagnetic-lock-p-1609.html). need find solution power solenoid small (aka not large 12v battery). needs powered few seconds @ time activate magnets unlock lock. operates @ 350ma.

i bought 12v 23a small batteries hoping work, lock not activate automatically. i'm assuming battery not providing enough current, i'm not sure. thought 23a fine because need operate solenoid few seconds max.

if has ideas on possible battery alternative may not of though of or knows of way power 12v solenoid lower volt power supply appreciative. (would 2 9-volts or 8 aas best options?)

thanks in advance

your solenoid requires 4w operate, hold few seconds requires storing perhaps 20j or more,
beyond reach of reasonably sized electolytic caps.  ultracap possible, have
voltages of 2.7v or so, not match unless use boost converter.  you'd need ultracap
rated high enough current, , charge 2 aa cells series diode drop voltage
perhaps.

for instance:

a 23a battery have feeblest of current ratings, worse pp3 9v battery, , are
bad enough.

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....
