    Noob with ethics question, needs into

    well to put it in an easy way you have to find the signal, decode it and send it to your tv. having the knowledge you do for electronics shouldn't take too long. (coughs loudly and keeps straight face) there is another option if you want to, trying picking up other countries feeds. I remember...

    peltier air con

    I was actually thinking of using it to cool some water in some pipes, like a radiator and blow a fan across that. I highly doubt I will make something to cool a standard room but having something that sits on my desk and blows cold air in my face on 30 Celsius+ days would be nice

    peltier air con

    ok so I am more wondering about if it'll work as apposed to the electronics side of the following project so was wondering if a few kind hearted people could help If I was to take a peltier and water cool it, run said water through a radiator which in turn would be cooled by a swamp cooler do...

    Please Help. How to build this circuit?

    ok here is something that I have worked with before and it works I have just never put a good circuit to it. ok use the mains power to charge the battery, run everything off the battery. so if power goes off then battery drains. if power is on battery is charged. so if you need pulses or...

    Oxygen machine back up power

    ok if the new plug works then great. your concept is very much the exact way the wiring in a car is set out with the exception that in a car usually the ignition has to be on accessories for it to work. Flippineck's estimate on the battery is correct and a 100ah deep cycle battery would get...

    newbie with new project.

    so if I have this right you have 2 devices that you want to hook together, the ecaller sends out a signal via a 3.5mm jack. the decoy you wish to use with said ecaller has no jack so I assume it just does whatever it does when you put in batteries? ok the simplest way for me to get this...

    confused about controller

    ok for starters.... I would really appreciate this being written so I can understand it. CPU's come in various bits.... 8bit micro controllers through to 64bit CPU's.... there may be higher and even lower values but I cant think of them what are your wanting to do...

    Homemade High Amp Inverter Power Supply

    I was going to ask this but thought maybe there was a circuit I didn't know about (well there are billions of circuits I don't know about but thought there was one in relation to this) I know in a standard house in AUS we can get maybe 15amps and that's for the stove..... very rare to see...

    What are these things?

    gillang have you put an meter on the regulator to make sure it didn't fail? this might be the cause, if you shorted the rails you might have gotten a quick 12volt spike that fried a part

    So glad I found you!

    oh mighty god of beer we welcome you with open arms and hope you shower us with alcoholic gifts, in return we will make offerings to you of information and knowledge........ or you can just ask and we will respond lol anyway if you ever get bored and want to share some projects you have made I...

    What are these things?

    well something you could do is take a high quality pic showing the whole board, and then one showing the back..just because you can't find that schematic under that name, it may be a common circuit that that company decided to sell. or someone could trace it out and figure the value if we get...

    Homemade High Amp Inverter Power Supply

    an inverter uses low dc voltge to create higher AC voltage........ you saying you are using mains to output 200volts makes me think a transformer might be the best option....but having said that I really don't know what you want to do... unless you mean 2000 volts not 200 edit just saying 40...

    so..... I'm a new Dad!! :)

    so while the little one sits in my arms I have been getting bored........... so bored in fact that I have been on here nearly all day trying to keep my brain functioning. I sincerely want people to correct me so I learn something and stop the boredom from taking over... on a different subject...

    how to dim high beam of my car

    hey kapazo... just to clarify you in England too? ahuumifan50 is from there and is advising on the laws from that country. if not you will have to check what is acceptable by your local governing agency for transport. as stated the PWM will not work but with some ingenuity you could make a new...

    Air circulation circuit

    yeah you could..... but what are you wanting to find? and how good is your programming? there are sensors out there that detect CO2 CO and other hazardous substances. there are modules and libraries for these on the arduino and PIC controllers. these can also be powered via the 5volts of a USB.

    Universal CNC

    ok so there are copper pens (THEY SUCK MORE THAN THE VACCUUM OF SPACE but can be used for this) there are also people developing conductive inks that you could use for making PCB's and as for that 200mm lead screw.. that's great and all but that makes the overall height at least 400.... My...

    Creating a game system from scratch. Where to start

    ok an extension of what dave is saying is what do you want? antialiasing? 1gb dedicated? what processor is it that you are using? now the basic PC uses x86 chips(someone is going to correct me I know) but the pi that is a 700mhz computer uses a different cpu from the ARM family. as such certain...

    Universal CNC

    ok my advice is jump on the reprap wiki and post some info there. they have a heap of forums too. the software they supply as open source from Marlin through to teacup will be a great start as people use this for milling machines all ready. I did see a model recently that attracted my...

    Creating a game system from scratch. Where to start

    ok time for some reverse engineering, if you want to know how its done find one and pull it apart. figure out what each part does, every single part too don't forget a capacitor, resistor or chip. next step is an operating system and you have to know your board back to front so that you can...

    Air circulation circuit

    very simple electronics side. you need a 5volt fan. now filter and air mask is not something we regularly take care of but charcoal filters seem to be the best and breathing masks are found in chemists here in Australia so depending on where you are you should be able to find one in a shop or...
