Hi We are planning a venue that consists of 5 specific sport oriented challenge zones that relate to specific sports. Golf, basketball and soccer. What we need is for someone to design the mechanicals for each zone that would show via a scoreboard wether a challenge attempt was successful. The system would have multiple sensors etc.. that would control audio and visual outputs as a challenger navigates through each challenge. A combo of audio and lighting effects would be turned on and off as the challenger progressed. Every challenge zone would also be connected to a central leader board that would update automatically if someone managed to complete a challenge or part of a challenge. Eventually the system would have connectivity to a venue app and the venue website. What we wanted to know if this is something that falls under your specialization or could you direct us to someone else who could help. Our preference is to stay with someone within the Elance community. I can send y...

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...

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...

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 ...

Need a PCB designed in Altium from a schematic that is 90% complete. I have the schematic in Altium format which need s to be modified to suite the modified design. You must have the ability to be able to advice the design process and choose appropriate components if required. Board is made up of 2 parts that connect together using a variety of connection options. Please sign the NDa to proceed and have also attached general view of PCB design i want Deliverables Be able to communicate and discuss on skype if required. Completed PCB design ready for manufacture. Completed source code of design in Altium format. Board can use the largest SMD component so it can be hand soldered if possible.
