circuit diagram requst

I am making a life sized 'operation' game for a fund raising event. I am fine with construction and artwork, but need a circuit diagram for the electronics, can anyone help please? Doyou recall the kids operation game where you have to remove bones without causing the buzzer to sound or the red nose to flash? I want a circuit (battery powered) which when tripped by some one touching the probe against the metal edge will make the nose flash for about three seconds and also trip the buzzer to sound for about the same time. Any one know how to do this please?

What is this wiring diagram symbol? Answered

It's part of the power supply circuit and probably has something to do with the wall wart power supply, but I'm not confident enough in that explanation to move ahead with it.

How would I set up a trigger on one relay with multiple pushbutton inputs?

I'm looking to set up a 12 volt system that has approximately 12 buttons that will each trigger an individual relay and a shared relay.  So I will have 13 relays (numbered 1-13) and 12 buttons (1 -12) - Button 1 will trigger relay #1 and #13, Button 2 will trigger relay #2 and #13, etc.  Wiring up a single relay circuit is easy enough, and I think I can set it up with an arduino or similar IC, but I'm looking for a discrete circuit design.  Would a simple diode on each circuit leg be enough?  If not, what would I need?

what is the schematic diagram of inductive sensor?

It is being used in a magnetic pick and place machine using four bar linkage. The inductive switch is being used in such a way that if the metal ball will be detected in the detection area. the four bar linkage will move towards the ball where the inductive switch is located, and carry and transfer it to the desired area.

Circuit Diagram Experts Needed. Thanks. Answered

Hi, (I posted an image)I found this circuit in an book of mine because I wanted to build a VU meter. I only want to simplify this circuit. I don't need sound coming out of the VU meter; so I could have just remove the speaker and be done with it. But... is there anything else in the diagram that is only related to the speaker in which I could remove? All I need from this circuit is the led reacting to the audio input like a VU meter. Eliminating unnecessary parts will help me make it smaller. Thanks! Helpful things to know about diagram: Ignore R1, C5, U2.... those are just references to another diagram. 324 is an Operation Amplifier IC (there is only 1)546 is an Audio Power Amplifier IC (there is only 1)the Si is a silicon diodethe VR is a 50k ohm control volume (potentiometer?)6 volts going inIgnore the funny looking earphone, thats the audio input instead.I posted one General Image and 4 close up Images. Any other question about the diagram feel free to ask.Once Again Thank you for helping a newbie.

Elta 8915 equalizer wiring diagram

Hi guys, I'm having a problem with Elta 8915 equalizer and I need help. When I hook it up on a radio and turn the power on, the lights on equalizer are on but not a single sound from it. When turned off the speakers are having a good quality tone from the radio and I can use fader on the equalizer. So, I either don't hook it up properly or it is broken. All the contacts seem fine to me. I do not have wiring diagram, and I've tried my best to do the proper wiring (there was no smoke so I guess I did a good job,haha). Is there any suggestion or the wiring diagram?

Wireless circuit diagram needed for an Electromagnet.

Hey guys, i urgently need to build a wireless circuit using a simple on/off electromagnetic circuit that would drop a metal object when the circuit is switched off. i have a 12V dc powered electromagnet as well as RF receiver and transmitter pair. the receiver needs to be fitted with the electromagnet and i would be using 4.5v dc power supply for the receiver using 3x1.5V button cells. Kindly help me with circuit diagrams and/or a list of other components such as generic IC/ timer 555/ resistors, capacitors, etc. which would be needed for me to build the circuit. Thanks a lot.

Help with an old circuit diagram, please?

Remember my inductor thread?Well, I'm getting closer to my project. The bulk of the device is to be based around an old transistor radio. I've got hold of one (a Phillips D1018/05, if it helps).Wonderfully, I opened the radio to find it has the circuit diagram stuck inside the back cover.Unfortunately, it's only half an inch high, so, I've scanned it.Now, I have a problem:The directions I am working with are vague:Try removing the Ferrite tuning coil and then replacing it with (another detecting component which I have, but if I name it the surprise will be lost) with a 12mH inductor connected in parralel.Spelling aside, I was happy with this, until I opened the radio and found that the antenna has four wires connected to it.So, I need a few answers:In the circuit diagram, which part is the ferrite tuning coil / antenna? I think it's part of the bottom-left corner of the diagram, but I need to confirm this.The four wires all disappear through the same hole, but one is stained blue and one red - which ones should I be dealing with?The component I am replacing the coil with is polarity-sensitive. The vendor was very careful to indicate the negative electrode - which way round should I connect it? I think I need to connect the negative of the component towards the bottom lead of the circuit diagram, but I want to make sure before I kill the component.I know these are potentially-noob questions, but this is my most expensive project so far, and some of the parts required subversion to acquire, so I don't want to mess it up.(If there's anything I've forgotten to ask / say, please let me know that as well. I'd rather not reveal the nature of the final project; it's not for a contest, but there's nothing like it on the site yet. If useful advice depends on knowing what the component is, then I will reveal it, but I'd prefer not to spoil the big unveiling.)
