    How much Hydrogen and Oxygen released..

    i can understand the logic behind using H2 to help take the reliance of fossil fuels but in reality its alot harder than it seems. another thing to point out is that while elctrical heating is coming along fast, as an ex-chef I can tell you now gas was always better, instant heat to the pan...

    Need help selecting an Emergency Stop

    with coca colas idea.... why can't you ziptie a plastic bag over the machine ALL the time? this will prever everything (or alot of stuff) getting in there as well as allowing the button to still be pushed. the added bonus is for oh&s you can simply remove the ziptie and bag whenever you want to...

    el wire

    Dunno if anyone has played with it yet but have a really weird question I have seen tutorials and explanations on how to solder it to the inverter, thats nothing too hard. the issue I have is I can't seem to find out if the other end is cut do i simply cut it or do i have to connect the...

    arduino is it all its cracked up to be?

    would it be wiser to make my own board for prototyping? i want something easy like arduino, how hard would it be to do that? and another thing is I am having an issue with digital and analogue parts, to make life easy I am just making this for output but the idea is that i contorl the speed of a...

    Triggering relay with 12v

    if you are really concerned, try adding a LED and resistor. this will give the added knowledge the switch is working and the circuit is closed

    tens machine

    those bands give us the resistance value. as shown above. to have a precise match we will need a pic and all 5 colour bands, all i can tell you at this point is it is either a resistor with a starting number 1(1k,10k, 0.1k.... unknown) with +/- 5% tolerance or if the end band is yellow not gold...

    arduino is it all its cracked up to be?

    what about limitations on code length and cpu handling? I know to not expect them to be as fast as a desktop, laptop or even a smartphone, but could i use it for example to display a map, recieve a code via 433mhz(or other) then display that on the map? i know most of its coding, and...

    arduino is it all its cracked up to be?

    as the title says. I am trying to figure out whether to spend time on it or to go straight into the high end stuff? I figure arduino is great for newbies like me trying to make stuff but the limitations are they too extreme?

    Super Powered Battery?

    this has stepped up a bit from where we started, now we know its use. ok for starters is it absolutely necessary to be electrical? because there are heat pack available and are alot safer then electric ones, especially inside tents. if it absolutely necessary then how long are you looking at...

    Super Powered Battery?

    batteries usage is usually defined in ah(amp hours) or cc(cold crank amp) the latter is usually found on car batteries to show how many amps it can provide at most to turn the starter motor which in turn cranks the motor into running. the previous one is usually a deep cycle battery. now the...

    Super Powered Battery?

    hey thesystem, got a couple of questions in relation to this, please define portable? for me portable is carrying it around, but in the case of a refrigerator that is kind of hard to do lol. there are MANY things that are going 12v for cars and camping. and for some things you can buy an...

    1/4-inch-to-1/8-inch plug adapter

    the colours for each chord may be the same or may be totally different the idea is to use a multimeter if you have one or if not a 1.5v AA battery and a globe from a torch to figure out which wire is which. on a stereo plug there are 3 connections so 3 wires. on mono there are 2 wires. you...

    Help with holding circuit.....

    I agree totally with cocacola(except for the name... coke zero would have been better) I am currently working in security and love the design aspect of securing a house including alarm installations. making something yourself is fun but it has to be tested, look up 12v alarms and find what you...
