2.1 Part A ? Thermostat Design You are required to design an ON-OFF controller that will control the cooling of an industrial refrigeration cabinet used for the maturing of beef. The beef maturation process requires that the temperature in the cold cabinet be kept between 1C and 4C at all times. The reduction in the temperature is achieved by switching on a cooling element (as in a fridge), and the increase in the temperature is due to the ambient temperature in which the cupboards is placed. The controller should output a CMOS level voltage such that: ? To turn ON the cooling of the cabinet it should output and hold a logic level of '1' ? To turn OFF the cooling of the cabinet it should output and hold a logic level of '0' The design should use a thermistor to gauge the temperature in the cabinet, and the logic for driving the output of the controller is as follows: ? When the temperature of the cupboard reaches 1C when dropping, the cooler shall be turned O...

I want to make an iPhone case that requires very complicated electrical engineering. This product is very complicated in its design and functionality. I have always wanted to build such a case as a personal project and now that I have the basic understanding of how to do so, I am looking to hire a small team of individuals to make this happen. If you have experience in micro-generation of electricity and electrical circuitry, then this job is for you. Please get back to me if you are capable of doing something of this nature. Thank you for your time and I look forward to your response.

The project is for a small consumer product that will use motion control to activate a light. The heart of the project is a Printed Circuit Board with a Microcontroller (MCU) and an Accelerometer (ACCEL). The device will need to be configured to run on the lowest power possible, with the device going into low power, or sleep mode in-between each MCU cycle. The device will run on 3V power using a re-chargeable Lithium Ion battery. The PCB will need a charging circuit, a low voltage cutoff circuit, a USB plugin connector that can communicate to the MCU and recharge the battery. The electrical engineering requirements are as follows: -Finalize decision on which MCU to use (current proposed MCU is PIC24FJ64GB002) -Design charging circuit and low voltage cutoff circuit -Capture and layout PCB with, charging circuit, low voltage cutoff circuit, Micro USB connector, low battery LED, power connection, mode switching button, necessary load switching circuits, and connection to an on / of...

The project involves development of a device to prevent accidental abandonment of children in cars. This can and has often lead to severe injury or death to children, especially due to heatstroke, in warm countries. Several solutions to this problem currently exist. However they are expensive. The aim of this project is to create a very cheap device that can address the above issue. A general scheme is already available and appears completely feasible. i am seeking someone with both engineering and manufacturing background to assist in the development of a prototype for the device based on the existing conceptual plan.

This is unrelated to my previous job entries as it is a personal requirement. I am looking for an engineer capable of preparing a detailed electrical, network (internet connection, phone, CCTV etc) and plumbing plan for my house. Currently the house is awaiting permits to be redeveloped and I need someone who can design the new plan. This would entail, among others, the preparation of the plan showing clearly what everything is, where the points will terminate etc. A BOQ which will include all the material required and all works required. A literature explaining why that design was used and what material is being used, why etc. In terms of lighting I would also expect the workings sheet showing that certain standards are being kept to in terms of good light ambiance etc. I would send the person chosen the autocad drawings of the plans and we can discuss what is required where etc. The house itself is 2 floors, around 150sqm per floor. If interested in the job kindly submit your offer ...

We have a battery power distribution product which utilizes an optional remote switch. We would like to revise these products to wirelessly interact with each other; allowing the switch to monitor the distributed battery level and provide indication of reverse polarity error. All indication on the remote would be made through dual color, switch bat LED's. For the distribution unit, we would also like a cell phone application for Iphone and Android. The app is to monitor the power distribution and have the ability to turn it on/off. Sensors would be developed to monitor current draw, voltage, battery capacity and other battery information when possible. The devices will need to consume very little power and add very little size to our existing units. We hope to have development finished in 10 weeks' time. We are looking for a hardware integration specialist for BLE and microcontroller integration, and also a firmware/software app programmer, but would prefer an engineer that c...

FAB Creations LLC is a trademarked brand currently in process of sales preparation for a new patent pending boot accessory. Current prototype is made of foam like material. Looking for someone to assist with both determining best material for the product without sacrificing quality and intent of designs, as well as someone who can mass manufacture product for sale. Material for construction must be flexible enough to wear but sturdy enough to keep original shape. I am looking for a creative and experienced manufacturer that can run with the vision and make it better than I can imagine, at reasonable prices. More information can be shared once negation begins. A signed non-disclosure agreement is required upon negation and/or acceptance of a bid.

I need an electrical component designed for a project I am working on. The project is 2 ft by 2 ft tiles that will be attached to a ceiling or wall and allow for me to make an LED star system that can be expanded or reduced by connecting or removing tiles. The tiles will need to use LED lights and fiber optic cables that are fed through preformed holes in the tiles and plug into a standard US outlet or an a joining tile. I also would like to create a twinkle effect with some of the cables. I have attached some preliminary drawings of what the tiles will look like.

Would like a design for an SSPA of at least 30 db gain, which will produce 1KW at 1.3 GHz. Linearity not an issue, but output power must monotonically increase with drive (no oscillations or spurs). 5% bandwidth is sufficient. Cost of first prototype should be separated out. Design will eventually have to be power combined later, so power combining experience is a plus.
