Treat this as a simple iPad controlled relay ? I want to be able to: - Log individual and team times - Reset the targets remotely (linear actuator or spring return?) - Show a 'starting LED light' to commence the shooting - At night, Illuminate all the targets with another LED which will go out when the target falls down (pressure or magnetic switch?) Brief: Design and development of an iPad controlled shooting target system. 2 teams will compete simultaneously to shoot down 5 targets each (total of 10 targets), first to 5 wins. The targets are 12x12" steel plates, approx 10KG in weight, supported by a torsion spring so that normally they are upright, once shot they will fall back flat, and then spring back upright again. Target reaction option 1). Normal Conditions - The targets once shot they will fall back flat, and then spring back upright again. Target reaction option 2). Competition Conditions - an electromagnet or other restraining device will be activated to catch the pl...

We need a custom built electrical switchbox. We have a computer control which will control this box with 12V DC signals. This box will have two inputs: AC power and four 12V DC signals coming through an RJ45 terminal. The outputs are four pairs of switched 120V AC terminals for controlling AC appliances. The appliances do not need to have AC sockets, as they will be wired directly by hand.

Investigation of ground based absorption heat pump for space heating and hot water production system Background Heat pumps can utilize low-grade energy sources, like waste heat from process industries and low temperature heat from ground for heating of building spaces and hot water production. It is believed that absorption heat pumps consume less energy than the conventional electric driven heat pumps and the student will investigate this based on ground source heat pump. this work involves more thermodynamic work and an Engineering Equation Solver (EES) software will be used. The projectwork include the following tasks: 1. Design mathematical models for compression and absorption heat pump cycles. 2. Investigate different possible working fluids, including, ammonia/water mixture. 3. Identify the influence of thermodynamics parameters for high performance of the

We have a PCB layout job that will take an existing .pdf schematic, adjust circuit design based on red line changes (mostly deleting a few sections) and then layout a new board based on a .dxf file of the board outline that includes all critical placements. the board is approximately 4" square and will be populated with about 80 - 100 components. We will order and assemble prototype boards here in house. This job may actually be two very similar boards with the identical schematic design. We prefer the Use of Eagle as it allows the most flexibility for us.

it is solar energy coursework ...It is estimated that Glasgow will need 3.2 x 107 MWh per year of electricity in 2017. A plan to meet this demand completely by solar energy is to be evaluated. Assume fixed solar panels of efficiency 20% and the ground reflection (albedo) to be 0.2. 1. Find the ideal tilt and azimuth angle for Glasgow. 2. What is the average daily electricity demand? 3. Which day of the year has the lowest number of daylight hours? How many hours of daylight are there on that day? 4. Between the sunrise hour angle and sunset hour angle, using an Excel spread sheet calculate at equal steps of 7.5o hour angles: (a) The zenith angle. (b) The angle of incidence. (c) The global irradiance. (d) The total irradiance. (e) The time average of the total irradiance (f) The answer from (e) multiplied by the number of daylight hours. 5. Find the total area of solar photovoltaic that would be required to meet the demand on this day. Write a brief report (approx. 1500 words plus any o...

Create the geometry of a rectangular Tank,dimesntions are Length = 1m Breath = 0.1 m Height = 0.98 m Simulate sloshing using Star CCM+ of membrane tank with swash bulkhead .The tank will be move in sway direction (left and right) which will cause the water inside the tank to slosh. Using VOF method, gravity, multiphase and VOF waves to set the ratio of air and fluid (just a suggestion). The boundary will be all walls as the fluid inside the tank is fixed.

This is a PCB design job. And I want you to use PADS for both schematic and layout design. The PCB is a PCIe card. I'm going to use the XR17V352 (PCIe-UART bridge) for PCIe interface. And the UART will be connected to microZED module. Simply say, This is for giving PCIe interface to microZED through UART interface. I want 2 UART connection to be connected between PCIe and microZED. I can't give you more information of XR17V352 because I couldn't find a reference schematic of it. And I want you to have some knowledge about the Zynq which is the SoC on the microZED because you need to understand it how to make the UART connection. It is basically nothing but a PCIe to UART bridge circuit attaching microZED carrier to the UART interface. So I want it cost effective, i.e. 2-layer design.

I am looking for an electrical engineer to design an electrical control box for an oven. I will need detailed specifications that I can use for taking in offers for parts and/or a fully assembled control box. Delivery is a list of components and schematics for wiring. We will only be making a few of this machine at this time, so I think it would be better to use PLC:s rather than PCB:s. The box will control one motor and two heating element arrays. The motor will need adjustable speed and soft start. The motor will also work and pause in intervals. The element arrays will be controlled individually and by a common thermostat. The elements will also be controlled with a timer. The machine will need an emergency kill-switch that turns everything(motor&elements) off Attached is a schematic representation of our system and our needs

This job focuses on achieving the best design for the product I have in mind. In this case the final design of the product is strongly related to the orientation and design of the chosen electrical components. I need consultation and direction on the electrical design and after that I need to narrow down the best design. I have some concepts in mind, but I need professional input. Only after the final design is reached, I will need a 3D rendering of the product. Details will be disclosed upon signing an NDA.

I have a patent on a CEILING FAN product I created some years ago. I want to create a sleek, more refined prototype proving the concept. This is the Abstract of the Patent: A fan blade assembly having both an electrical connection and a mechanical connection to a rotating hub. The assembly is configured so that a single installation motion creates the mechanical connection and the electrical connection. The electrical connection preferably includes multiple independent conductor paths. You can find a link to the patent here:   [obscured]  /patents/US20110085908 The project is for the design/prototyping of a fully working ceiling fan with detachable electrical/mechanical blades with LED embedded.

There are two parts to this item I want Built. The technology is already out there but NO ONE has put it all together it this venue. I need someone who is familiar with electronics that sense their environment and be able to collect that data and communicate with the Internet. Then this data will be used through an app to follow and make adjustment via wifI and the Internet. So the first step is to sign a non compete and get a mechanical and/electronic engineer to design the basic mechanics to work together. This device needs to be small and durable for almost any environment. I look forward to working with you. I'm
