    Rf transmitter with 2 receivers

    actually... just put all the logic at the receivers. leave the transmitters as is.

    Rf transmitter with 2 receivers

    and furthermore... Because you don't want both AFADs to go into slow mode, 'cos that would be bad... If at, for example, receiver 1 you made the STOP mode trigger if Output 1 OR Output 3 went high (so that'd be an OR gate). For receiver 2 it would be Output 1 OR Output 2. You might need some...

    Rf transmitter with 2 receivers

    Hope that was clear. If not... Each receiver has 8 outputs. Those outputs go high whenever a corresponding button is pressed at the transmitter. Both receivers behave identically. Output 1 goes high on both when the transmitter button 1 is pressed. Same for all the other buttons. Both receivers...

    Rf transmitter with 2 receivers

    Thinking about it some more. I'm not sure how much those evaluation kits cost; you'll need to ring and check it out. However, if they could supply an extra receiver eval board and antenna you would have potentially a complete solution. There are 8 buttons. If you set up both receivers so that...

    Rf transmitter with 2 receivers

    This could be a good place to start: https://www.linxtechnologies.com/en/products/modules/kits/lr-rf-transmitter-receiver-eval It's pretty well a complete solution in an assembled kit - buttons included! Check out the user guide.

    Rf transmitter with 2 receivers

    OK. In that case... You need a microprocessor controlled transmitter and two microprocessor controlled receivers. The idea is that the transmitter sends messages out to both receivers. The receivers are designated 1 and 2. Each message sent consists of an ID and a command. The ID can be 0...

    Rf transmitter with 2 receivers

    Totally possible because, you know, complete systems are available "off the shelf" http://www.autoflagger.com/products/autoflagger-76/ I have to ask, why are you re-inventing this particular wheel? I understand if this is a fun project, but if you're looking to save time/money/hassle then this...

    Rookie question

    Does your graphics card in the computer have two video out connections or only one? If only one, then it might be better to upgrade the graphics card to one that supports two outputs - ie: two monitors. Then it's just a matter of having an application open in one window on one monitor and a...

    DC Power Splitter

    dorke beat me to it... but you get the idea. For the purposes of this discussion you can use the equation Watts = Volts x Amps or put another way Amps = Watts/Volts. So for 10 meters at 5.76 Watts per metre gives 57.6 Watts. Then Required power supply current capability (Amps) = 57.6/12 = 4.8...

    DC Power Splitter

    Addendum: There are short LED light strips which can be powered from low current power sources (<100mA) If this is what you are after then you CAN use the splitter for these. You need to check the requirements of your lights. Also, you could provide several switched outputs from a single higher...

    DC Power Splitter

    Firstly, let's make a distinction between Light Emitting Diodes (LEDs) as an electronic component and LED lights which are "complete" lighting units ready to be plugged into a power source. You, I think (correct me if I'm wrong) , are interested in the second - the complete LED lights ready to...

    Lcd screen duplication

    The specs on the sph-da120 say it supports a rear display which can mirror the front display. Have you tried this?

    Lcd screen duplication

    Well... I was interested so I had a good look around. This company: http://www.siliconimage.com/solutions/mobile/hdmi-tx/ has several ICs which can convert 24 bit parallel RGB to HDMI. That said, the ICs are designed for very high density devices like mobile phones. They are probably not...

    Lcd screen duplication

    This one is tough! You have parallel RGB to convert to HDMI or similar. A quick browse on google found several solutions going the other way - driving a TTL display from an HDMI signal but not what you want. It is obviously possible but not obvious how... I'd go on a google hunt with something...

    audio glove ... project ... thing

    The advantage of "plug-n-play electronics" is that most of the time you're plugging things in to each other with just the occasional soldering job. You get to learn basic low voltage electronics along the way. Try here as a start...

    audio glove ... project ... thing

    look here: http://www.embedded.com/design/real-world-applications/4431259/The-basics-of-designing-wearable-electronics-with-microcontrollers and then keep looking and learning. Firstly get a very simple project working on the test bench - eg: 1 touch sensor connected to whatever small processor...

    audio glove ... project ... thing

    Food for thought: Kinect, gesture recognition This would enable the use of gestures without a physical glove. There is PC software available for the Kinect and there are other gesture recognition systems around. Unless, of course, it HAS to be a glove.... then you need touch sensors embedded...

    Burglar alarm - Can it be done ?

    I suggest that you ring the supplier/manufacturer and ask if they have an alternative to their keypad entry system.

    Controlling multiple TVs with buttons

    Does the sound need to come from each TV? That is, from each individual TV's own speaker. OR Is it ok for the sound of all TVs to come from a single speaker? For the last option (single speaker), Martin's mixer solution is probably easiest. Otherwise the solution is a little more complex.

    Scary...

    Well, I see an insane post which is responded to with somber reason only to have a response something like: "I don't see why the people on this forum feel the need to lecture me on safety standards. All I need is the circuit. I have the 5Kv transformer and I just need to create a controlled...
