I recently ripped apart a Sky+ box that was out of use. Of course, it contained many parts. Quite a few tact switches, a few LEDs, a lot of capacitors, lots of resistors. One of these parts was a little metal cube with a black sphere protruding from the front of it. This is the IR receiver for the remote. I wish to incorporate it into another project. The first problem is I don't know how to use it. It has 3 "legs" - 3 metal contacts. The second problem is I can't easily experiment with it as I inadvertently destroyed my breadboard earlier. A new one will come as soon as I can manage, but until then..... My question is this - any ideas how it would be used? Thanks in advance, ~H4ZZ

I want to make a gadget which sends a few kb of data via infrared and also receives data via infrared with a timestamp. However, I am stuck as I have only used arduinos before and I have to design a circuitboard which I have never done before, with PIC microcontrollers (must be cheap ones). I need help a) choosing a microcontroller and b) assembling all the components into a circuitboard (ir transmitter, receiver, microusb port to transfer data to pc, battery). Gadget will eventually be portable so make everything light. Thanks Khalid

Is there any device that you can plug into your router in one room, and then connects wirelessly to a receiver in another room, and then that connects to a device such as a laptop? What I am looking to do is take the ethernet jack that is in my moms office and hook the transmitter up to it. Then take then take the wireless receiver and put it in my room to hook it up to my Apple Time Capsule. From the Time Capsule I would send the wireless signal to my laptop sitting right next to it. If you are thinking I could just hook my Time capsule up to the modem in my moms office, thats the way we have it set up right now, which gives me a very weak internet signal, if any, so if there is any device that will do this it has to send out a stronger signal than the Time Capsule. If you don't understand what I was saying you can look ant the diagram below. Is this possible?

Hi everyone, i looked at the instructable of the wokfi antenna and the site of where it all started on that topic ( http://www.usbwifi.orcon.net.nz/ ).i found a free wifi access in my area, i got 1 pc (ethernet card+ usb wifi dongle), one laptop (wifi), a nintendo wii (wifi) and an old pc (233mhz, ethernet card) also a spare ethernet pci card and a pcmcia wifi not in the laptop, laying around .here's what i would like to do to have internet for free:- get the signal from the free wifi access point to the 233 mhz pc- use that pc as a firewall- then send the signal thru the ethernet cable and with another wifi (the pcmcia in the pc with a pcmcia to pci adapter or another usb wifi dongle, witch ever is cheaper) because my laptop can't reach the free wifi access point, it's to far..i'm looking for help on this please, i'll do an instructable with it because i think it could also be usefull to other. that whole idea of free wifi to anyone could be used here. because, let's say in a block, dorm, appartment a far away wifi connection could be shared localy. i've been digging for an intense 2 days now but my knowledge about networks and english (my first language is french) aren't that good so if anybody got an idea where to start looking it would be very appreciated.

Hi everyone,I just wanted to know how I can send a small electric signal over a distance(not more than 10 meters)wirelessly and receive it at the other end to trigger a relay which in turn of course.. switch higher voltages and do something say...light a LED.I don't know much about frequencies,oscillators and FM/AM or anything.So please let me know how I can get an idea about these and most importantly accomplish what I just mentioned above.
Question by Adarsh_tronix | last reply
I am looking for a cheap solution to transmit and receive 4 channels of audio.Transmitter may be bulky, but the receiver must be small. (it is for an interactive installation)Audio The 4 channels will be converted to 2 channels stereo, so in total 2 stereo signals of audio need to be transmitted and received (within ~10 meters). Note that achieving the best audio quality is not of top priority.Technique Should I be looking at FM / AM of Bluetooth methods? I've looked at: https://www.adafruit.com/product/1958, but it would be nice if there is also a paired receiver board.It would be nice if the proposed solution is scalable to 6 channels (3 channels stereo).

Question by jules15 | last reply
I have a DTH satellite receiver which has a burnt SMPS power supply (image attached). I replaced the burnt components but again when powered with 220V ac supply to test the output voltages the same components burnt again within a few seconds. I could not figure out what is the actual faulty part. If anyone has any suggestion please feel free to answer. My second problem is the satellite receiver board (image attached) has 6 pins for power connection but I could not figure out what voltage is to be applied to which pin. So I was unable to use a separate power supply for the receiver board. The part number can be seen from the image itself. Please look at the receiver board and help me if anyone has any idea about this board. I tried searching in google with the part number but could not find the same board. Please help me. Any suggestion is welcome. Satellite receiver: Hicway ali M3328C(10039)-11

I am trying to connect 4 ESCs with a FlySku 6 Channel Receiver. I managed to connect all four of them to the throttle channel and it works fine. However, is it possible to connect them to other channels wiht them being plugged in the throttle channel at the same time? I am making a quad-copter and I am not sure what channels to use? like I know that we need the throttle channel to change the throttle and the motor speed. but like to change the pitch, roll and yaw, we need the other channels too right? So can anyone please guide me through it? I am using a flycky CT6B transmitter and a 6 channel receiver.

I'm looking for a breakout board, module, etc that is basically a 40kHz ultrasonic receiver, where if it detect a 40kHz signal it puts a pin high sort of thing (volume level as a PWM whatever, I just need to know when there is a 40kHz signal near by). I was thinking of using a HC-SR04 Ultrasonic Range Finder but they only receive for a very short time after the trigger pin goes high, I need it to constantly be sensing.Ideally works with a Raspberry Pi (ie 3.3 volts output, but 5v just means I add a voltage divider not a biggie)Thanks

Hi everyone. I have this problem I don't know how to solve. Recently I bought a Linocell Bluetooth Music Receiver to plug in my car. I wanted to rip away the battery and make it to turn on when I turn started the car. The problem is that the On/Off has two functions: 1. The obvious On/Off function (holding the button for 3-5 seconds) 2. Search mode (holding the button for about 10 seconds) How and what do I modify for it to work the way I want? I can upload a picture of the circuit board if it helps.

About a year ago I got one end of an wireless microphone system at a yard sale. As far as I can tell, it is the sending unit. The recieving unit is lost to posterity, which is why it was so cheap, and has since been collecting dust. It has an RCA line in, 1/4 inch microphone in, a squelch knob, an output knob, a two-foot antenna, and a power button. It says it operates at 49.83MHz FM. I don't have a receiver that will pick up that frequency, and I'd like to know what it would take to build one. Perhaps mod an existing FM radio?

Hi all. I am trying to make a circuit that would help me find lost keys. It would be a simple beeper/ noise maker triggered by AM (for simplicity). I want it to be small and, if possible, cheap. What would be the best approach? Should I use the incoming signal to 'trigger' a 555 oscillator or should I send the 'beep with the signal (The transmitter can be as big as required)? Also, most of the circuits I found online were for tune-able radios. If I want to center mine at 1 MHz and if the quality of the sound is not important, how simple can I make the circuit (while still keeping it sensitive)?

Hi, i am planning on buying, and another instructables member already has, buying this wireless receiver (comes with a transmitter), for use in whatever we desire to use it for! heres lins to two images of it, i dont understand a bit of it, only i see the inputspostive and negative, and the outputs positives, but thats it , which make no sense to me. http://downloads.villageorigin.com/001540-015/Diagram%202.JPG http://downloads.villageorigin.com/001540-015/Diagram1.JPG anyway, what i know is where the positive and negative terminals are, also, the othe rmember has already tried running this using the ground terminal as the negative for the outputs, but says it does ot work at all, and that is the only thing which seems to make sense. also, this is the only thing the ebay seller could give me in regards to operating and installing this chip into anything, because they know nothing of it, and asume that the ebay users who buy it already know how to use it. anyways, there are several ports d0,d1,d2,d3 vt, vcc, and ground al the d's are the output ports, vt is called switching voltage and is assigned to an output depending on what button is pressed on the receiver, and thats all the information i have gotton. and from what i know, its inoperable, but then again, i dont know much about that stuff also, who ever shos me how this work, i promise wil get a "best answer" from me.
Question by oldmanbeefjerky | last reply
I was planning on making a top secret circuit board. One of the thing this circuit board needs to be able to do is to receive a radio signal (I think radio would be the best for this because its simple, and can be transmitted easily through walls, but tell me otherwise). The radio transmitter would only have to send two different things, such as on and off or I and 2 for example. Because of this, I wouldn't think I would need anything hefty to receive/send. I'm not 100% sure if I can easily translate either of these two signals into a circuit board so that I can easily say: if signal = 1 then function 1 else if signal = 2 then function 2 would I need another part to do this? As in if I receive signal 1 then it activates wire 1 and etc. I'm mostly looking for a part that I can purchase for the receiver and transmitter (the transmitter does not have to fit on a circuit board), but would be happy with some DIY goodness as well. :) Thank you for your help

Question by Blechmen | last reply
So, to simplify things, I want to power a heap of LEDs that run off exactly 5v of power when I press a button (and stop when I release) from 300+ meters. I'm looking for a radio transmitter that has around 300+ (bigger the better) range that can communicate with a large heap of receivers. I'd prefer if the receivers are fairly cheap because I'll be using them in large quantities, but I'm happy to spend under $100 with the transmitter. On use, I want the receivers to output 5v of power into the LEDs. The transmitter doesn't need to transmit anything special, just a signal at all will suffice, with an easy on/off switch on it. I'd be happy to lower my range to around 200 if necessary, but its not really ideal. The receivers need to be fairly small. Thanks a lot for any help/suggestions :). My electronics knowledge in this area is fairly limited. Thank you again

Hi, I have a Vellerman K8055 USB experimental board that I have hooked up to one of my machines. Yesterday, I took our wireless doorbell apart and with a multimeter found the signal that sparks the 'ding-dong' sound when the remote bell is pressed. I wired that into the K8055 and then to cut a long story short, when the bell is pressed, it pops up on my TV and tells me that someone has pressed the bell (using MythTVOSD multicast if anyone is interested). A link to the card: http://www.velleman.eu/products/view/?country=be⟨=en&id;=351346 What I'd like to do is to extend this mechanism to my doors. When a door is opened in the house, then I need a signal to be sent to a receiver device also wired into the K8055 so that I can capture that event in my program. I have thought about using magnetic reed switches on each door with hacked wireless doorbells (around 3-5 GBP on ebay from China). One problem I have is that I can only find 'normally open' reed switches, meaning that when the door is closed so will the reed switch contacts - this in turn means that I will be constantly notified (should I be able to make this work) that the door is closed. If I could find 'normally closed' reed switches, I could have one of each on each door, What is the cheapest/most elegant solution to this problem? Is using hacked wireless doorbells the way to go, or is there a better way. I'm a relative novice with electronics - I'm a dot net developer by day with experience of data capture cards, and have toyed with the Arduino, Lm386s, 555s, 4017s etc... some with instructions from this site, so whilst not a complete beginner, I am what I would call, "an enthusiastic amateur'.
