    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 ...

    Background: A completed Orcad Schematic Design was laid out by a DipTrace designer. This designer is no longer available. The reference designators are common, but there is no common netlist to verify the layout. This layout needs to be updated, DRC'd and/or possibly moved to Cadence, using the existing layout as a template. The Work Required: In addition to DRC and updating the layout per the DRC results a few small changes need to be made. The changes ...

    I was recently inspired by the Arduboy - an Arduino business card that plays Tetris: http://www.bateske.com/arduboy/ I would like to create something similar: Instead of controller buttons and Tetris, I would like it to have 2 biometric leads (1 for each finger) and the ability to measure and display the user's Galvanic Skin Response (GSR). Galvanic skin response readings are simply the measurement of electrical resistance through the body. Two leads are touch to two fingertips ...

    I have attached a model from matlab example. I have to make a model like this or much easier format. PV module Boost Converter Inverter connected to the Grid. In the Boost converter I have to implement MPPT logic. Aim: PV array output characteristic changes with weather therefore a DC-DC converter is used to extract maximum power by changing its duty cycle according to MPPT logics. The system implements three most popular MPPT methods to extract maximum power: Perturb and ...
