    I want to create an app for my smartphone, but I realize now that I need to create a very simple, small bluetooth 4.0 device first. I want it to be small and pocket sized, something that could easily fit on a key ring. It should have only a single button. It should have the ability to be tethered to a smartphone (both an Iphone or an Android) via bluetooth 4.0. When that button is pressed, it sends ...

    We are trying to build an inspection camera for to be used for inspection of pipelines and similar. The camera system will be running of 24V DC and should be made as simple as possible to ensure reliability. We require someone to design the circuit and then make the PCB design We need to have it using the Aptina MT9T031 CMOS CCD sensor and going into a fibre optic signal. I will need it to go from the CCD through ...

    Objective: Design a circuit that isolates a battery from its charger to prevent discharging the battery. This would be a fun but challenging project for a EE student. I am hoping to build a relationship for future work. It should use a FET since the voltage drop when on must be 100 mV and when off must be 4M ohm. Connections: Input1: Charger. Up to 4.2V when on, 20 uA load when off. Input2: Charge Control: Open collector, closed ...

    We are a startup that teaches Neuroscience to kids. See our TED talk at http://on.ted.com/Gage to see what we do. The amplifier used in this talk is called the SpikerBox. We love to use it in the classroom, however the speaker is too quiet. When we try to turn the gain up, it becomes unstable. We therefore use a cheap external battery operated speaker from Radio Shack. It is much much louder. We have noticed that ...

    Hello I am working on a small moving toy based project for which I need just the C Code. For this project , i have already purchased the hardware and now just need to get the C code for it. I need a code for three things :- 1. DC motor 2. Servo 3. Sensor Once I have the code I can burn it into the AT89S51 Microcontroller and will do the wire connection and it should work. Please get the details ...

    I need someone to develop an electronic circuit for a floating swimming pool alarm. The main components of the circuit will be: a solar panel; a rechargeable battery; a micro-controller; an accelerometer; and the buzzer. I need someone to simulate it in a specialized software; to develop all the technical documentation, the list of the necessary components (with costs) and a prototype of the circuit, so I can test it before manufacture. I already have the plastic floating case in ...
