Are you an expert in Hobby Electronics? Propose a plan for $30.00! (Allow 1 - 2 hours to write your proposal.) Here's my idea ... I have a 'normally closed' lever switch and this means the 9 volt LED which I use to test this switch goes OFF any time I press the lever. I need a tiny circuit designed to handle the same. More specifically, I'd like a circuit board made with a 9 volt battery snap 'to connect the battery' ... and another 9 volt snap 'to connect whatever is to be powered' (or just connect 2 wires to a 9 volt LED to test the circuit). On this circuit board must be a couple of wires labelled 'Event Wires' and if I make these 2 wires briefly touch, doing this must accomplish the equivalent of what a lever switch does (in normally closed switch). If you'd like to design the above explained circuit on a bread board then write an easy to understand schematic showing me how you did it, and you're willing to bid between $100-$150 for doing this, please do! But first bid $30.00 on this 'preliminary project.' For $30.00 you can 'commit to writing a proposal describing your general plan.' Then the $100-$150 bid can be for the actual work you agree to do next project. P.S.: I've been told that a circuit that detects a power fluctuation when 2 wires touch could be made to briefly disable a 9 volt output.

Hello Sir, We are team of fresh undergraduates willing to complete this project. We can complete this and show you the working prototype. After that if it is up to your satisfaction then you can continue with us. Please contact if you are interested. Thank you. P.S. Here is a brief introduction on how we are going to accomplish this. We are going to use transistor biasing to accomplish this task. We would adjust base parameters so transistor would conduct whenever the event wires are touched. We have done with breadboard design. If you initiate a conversation with me then i can send you the video. Thank you.

i,ll use a comparator to compare two voltage coming from 9V battery and 9V from wire. if there is any fluctuation in wire voltage then a signal will be generated which will inform us about any disturbance. please inbox me for further discussion.

I use BJT in EC (Emitter Common) mode to do this project. When two wires are connected, BJT is turn-off that turn-off the led.

I"m an electronic engineer currently working in an R&D organization. I have got experience in circuit designing, simulation using different softwares and PCB designing. According to my understanding, you need a circuit which will emulate a lever switch and it has to switch the led ON and OFF depending on the position of lever switch but this has to be performed by touching two event wires in the circuit(by short circuiting them). And you mentioned to connect a 9V battery to power up LED. I have designed and simulated a circuit which contains the following components : 9V battery(V1), LED(D1), series resistor for LED(R1), actual load resistance(R2) and two event wires named "Event wire 1" and "Event wire 2". If these two event wires touch each other or are short circuited, LED becomes ON which indicates that the lever switch is in normally closed position and when these two wires are disconnected, the LED goes off which indicates that the lever switch has been pressed(normally open position). I can send you simulation as well or a schematic in PDF. Furthermore I can also design a PCB for this circuit if you need. I am also interested to do next part of your project. Kindly let me know that is this you actually require which i explained above ? Looking forward to you for further elaboration and discussion on this project and to award me this project. Best of luck ! Thanks.

The circuit sounds quite simple and I would love to work on it. The project would require just about an hour or two for design then building the schematic would be super simple. Thank you for your consideration.
