    Negative voltage: practical application

    ground is always neutral. consider that 0. + and - are the voltages away from ground. if I were using a transformer like you described and it read -48v grnd +48v and I required -48v I would use ground and -48v. if I required +48v I would use grnd and +48v. If I required 96 volts I would try the...

    i want to learn to code but.....

    don't put things on your resume unless you are confident with them. If you put it on your resume and are asked to do it and you can't then it looks bad, real bad in some cases.

    Waterproor threaded power sockets?

    http://www.jaycar.com.au/productView.asp?ID=PP0542 that is ip67 so hopefully iys a start and its panel mount unless you need this to go tottally under water than IP67 should suffice with ease

    Waterproor threaded power sockets?

    if you are in australia look up jaycar. they are my preffered site at this point but there are 100's of alternatives if you have time to research and wait for the shipping

    i want to learn to code but.....

    I agree with everything coca cola has said, the only reason I use arduino is my soldering is crap and there is a larger community to ask advice from. every single micro has its ups and downs. very few micros have the same pin layout. you NEED to choose the right micro for the job. and I agree...

    hobby time

    yeah I was looking at the solenoid approach, but I want a few extra shots before having to reload. I was trying to get something that would be easy to reload as well. I would ideally like it to be like a hand gun, magazine at the back it fires from back of barrel.

    i want to learn to code but.....

    I REALLY like basic cos it is BASIC. I still get confused with C on a daily basis, and I can interpret what a program does, or what a fault could be, but don't ever ask me to give you the right coding cos I still get stuck on library references and other little things. I really like basic and if...

    Waterproor threaded power sockets?

    there are a tonne of these connectors, you need to learn the IP system of coding to get your best match. http://en.wikipedia.org/wiki/IP_Code that link will show you the basics. In your case look for the second number to define how much water you intend this object to receive.... IPx8 will...

    Time for a moan about manufacturers

    couldn't you use a colour detector to detect the right colour of the toast and then turn it off? I suspect that different breads will be different colours so this may not be the best approach but for plain white bread it is a good idea I think.... that is if it can withstand the temperature of...

    Hello from a newbie.

    RF and robotics are both awesome ideas. I would be more than willing to help out when I can but I too only know enough to not fry thing too badly. and my soldering is worse than that. I can let you know however EVERY stumbling block I have come accross, someone on this forum has helped me with...

    i want to learn to code but.....

    c is standard, most micro controllers use c as do older games. c++ is advanced and changes around things so try using c first then adapting to c++ later. there are forums to help you I used one for a while until I realised my brain was not that good at computer coding. I did make some basic...

    hobby time

    I am loooking at foam darts, australian laws on projectile weapons are pretty strict so will not be able to get away with much else (we need a license to own a paintball gun)

    Laugh for the Day

    An old lady is pulled over for speeding by a state trooper. When he approaches the car she is giggling like crazy. He asks, "do you know why I pulled you over?" she responds "you don't know half of it" he says back to her "you were speeding. what else have you done" she can't help but break...

    hobby time

    OK so this has been taking some time but my mind has stuck. the base is easy as heck but I cannot find anything that will show me how to build the turret and get it to fire. I was thinking about destroying a nerf gun to get it to work but I was wondering if anyone had an easy method to do this...

    Soldering rod problem part 2

    the only reason I can think that your iron is now electrifying you is that its damaged, it should not be zapping you. it is a closed circuit that produces heat, either a lose connection or a broken heating element will be the cause of you getting zapped

    Thinking about making a blender?

    I am currently playing with arduino and some of its brothers (arduino is the brand but there are 3rd party equivalents). I can tell you right now that a standard blender can be made alot easier then using arduino. Arduino uses a microcontroller which needs programming. If you do get bored...

    Could anyone just take a look?

    ntiwari as with the above questions I add a few more do you require a broadcast license? are you aware of the implications of activating this device? and how are you going to stop it from interfering with other transmissions?

    Could anyone just take a look?

    we have VERY strict rules here in australia about broadcasting, this would most definately be illegal without prior written consent from a few organisations. I like the idea of everyone having a say, but it HAS to be monitored for several reasons and in this case it is so you don't use a...
