At work im using an electric driver that cant adjust its torque. Is there an extension i can buy that will allow me to torque it down? Even if its fixed at a relitively low torque that would be fine.

Basically i want to swap the chip out of my developer and into a more permanent project. One is just using basic i/o but the other ones need the pwm functions to work. I know i need a voltage reg and frequency crystal and the mem chip. Other than that im clueless thanks

im just looking for a way i can use a query to add data to a table? basically i want to make a set of 4 text boxes that will first add data to a table, and then return the amount of times that text was entered... i know the last part is easy, and i know i can make 4 text boxes pass the data as temp vars, i just need a way to add those 4 things to the table BEFORE i count them.

i got a week on salisbury beach coming up. i want to start fishing again so what better time right? well im not sure what type or weight of line i should be using. from what i understand, stripped bass and blue fish are the major catch's but theres been some weird catches coming in. i think im going with a steel leader because of the blue fish but besides that im clueless. i think mono would be better because its less visible in the water. but ive never used braided before. also i was thinking 20 pound would be a good weight? if i set my drag right i can land a 40 pounder with that right?

hi all, i have a laptop with a blown mohterboard, and the only motherboard i can find on line says "A1185802A" but the motherboard in the laptop has a label of "A1185803A"

are they compatable? im not even sure if those are model numbers or anything like that but that the only id # i can find

thanks

i was wondering if its possible to use my arduino to switch ac power? i would like to stay away from relays. im trying to avoid any moving internal parts. basically im looking to bypass my aquarium heater's internal thermometer, i have a ton of dead heaters that have broken internal thermometers. i want my arduino to sense the temp, and switch the heaters on and off.

thanks for any help...

is there anything special i would need to do to replace my arduino's memory chip? it the uno r3, with the removable tht chip. off the top of my head i cant think of the name... i do have the actual arduino, just looking to make my project more permanent

im following plans off this site:

http://www.instructables.com/id/Circuits-for-using...

(step 6)

and i am planning on using the same nfet as instructed as my electronics isnt up to par to deviate too much, i would like to run Q2 (Fairchild FQP50N06L) nfet with about 3 watts of power (2.8w to be exact). how big of a heat sink should i get for them to run safely? i was looking at some off ebay

http://www.ebay.com/itm/5pcs-21x15x10mm-IC-Aluminu...

would those be enough for the nfets or should i look for bigger?

im reading some code for my c++ final. and im not 100% sure i did this correct.

"Block* blockPtrs[4];" this makes an array of pointer to a class "block" my question is just this, would the memory allocated for the pointer be in the main memory or in the class "block": memory. this is for a memory map.

thanks all

im trying to make a function to take a float and multiply it by 5 then return that variable as an integer. but every time i run this my ide spits out a possible loss of data error c4244. how can i avoid this error? i understand im loosing data and i personally dont give a hoot lol. thats what its suposed to happen....

heres my code

#include <iostream>

using namespace std;

float mult5 (float n );

int main() {

float n;

cout << "what is your number? " << endl;

cin >> n;

int answer = mult5(n); // calls the function mult5 and set the return to "A"

cout << answer << endl;

system ("pause");

return 0;

}

float mult5 (float n)

{

float answer;

answer = (n * 5);

return answer;

}

thanks every one

Im doing a project for my college and i want it to be done correctly. I think the desks are made from metal and particle board. I need to attach a light peice of metal to the wood part but im worried normal screws would split or damage the desks. The peices are light but they will be touched often and might be bumped. Is screwing them in the best plan or should i look into epoxy of some sort? Thanks for any help

so i needed to replace the cooling fan and heat sink for a friend of a friend. i wore the esd protection and replaced the fan quite easily. now that everything is back together nothing wants to power up. the little led on the power button doesnt want to even glow. i dont have the cord yet but i think the battery was mostly full. any ideas what i could look into for maybe a loose connection or something?

i rechecked all the ribbons and that didnt help.

basically im looking for a program i can install on a flash drive to grab all the basic back-up-able files off a computer, videos and music would be a bonus but the pictures is a must. it would also be nice if i can use this with a live boot mini xp. because the OS is completely fried from where im trying to back up from. i think i saw a few programs ages ago that blindly did it, i dont care if it grabs unwanted stuff just need all the pics off the computer.

any ideas?

Ok ill cut to the chase. Im very heavy about 400 pounds and 6'3". Me and my girlfriend both want to loose some wieght by biking 7 miles a day all summer. She has 2 average 10 speed bikes down stairs that havent been used in 5 yrs. Would a normal bike/tire/tube hold my weight? The last time i tried to ride a bike was 6 yrs ago and it was a bmx bike. The back tire blew out and ive just never tried to ride again cause i think im too heavy. So can the average tire hold my wieght on streets, or should i look for something better? If at all possible something to mod the exsisting bikes as money is tight atm.

transform the given IVP into an algebraic equation in the s-domain and find Y(s)......

NO im not asking to solve my home work..... but i took the laplace transform for both sides and solved for "L{y}" where L{y} is the laplace transform. my question is, am i at the end if my teacher is just asking me for Y(s)? ie L{y}=s-1, would Y(s)=s-1 ?

i tried doing the inverse but it sounds like i need to keep without doing the inverse.... teacher isnt answering emails either lol

i have a transformer, 115V in and 12.6V out. (thats end to end, 6.3V from end to neutral.) i have access to an lcr and i just need to try to figure out mutual inductance so i can accurately map this transformer. i came across a formula that told me to measure each side, then hook them into series and measure that. (lt being both in series) ive come with the measurement 735mH = L1 7.4mH = l2 and 925mH = LT. the formula said M=(LT-(L1+L2))/2. but then with M= K (sqrt) L1*L2 (sqrt) the K comes to 1.2ish...... that cant happen. so is there another way to measure the mutual inductance? also can you tell me if i messed up some where or is that formula bs?

thanks for all the help

heres a problem im trying to solve. when selling tires for a local speedway, the drivers are trying to pull one over on me. they remove the given barcode and swap them around. i want to add a passive rfid tag to each tire, on the inside. i cant find much info on pricing for them or a reader. where can i start? i would like the about 5 numbers to come up, nothing too fancy.

any ideas where i can start? any idea on prices i can expect? all these tags are going to be one time use

my teacher has asked me to go out and find some batteries for set of solar panels and the only thing the instructions recommends is 12v. should i look for lead or some other matterials?

is it only the current potential of the batteries ? (AAA AA C D) i thought all of them were 1.5v (depending on the used materials of course.)

i was just wondering if using a AA -> D battery adapter would be ok to use? i have a few air pumps for my fish tank that goes off D and loads of rechargeable AAs thinking the rechargeable can be used to cut costs for use in a power outage

ive been looking around are cicuits that will produce current and voltage will vary. im interested in this for some led projects im thinking up. also id like something that i can use directly with 120V 60Hz ac. any ideas on how i can do this?
