Leapcraft (  [obscured]  ) is looking for a freelance electronics designer who can help with our projects to design electronics for small sensor packs and consumer appliances. The candidate should be proficient in schematic design with low energy system, experience with RF design and BTLE would be an advantage. The ideal candidate should also be able to effectively translate high level specifications as block diagrams and written descriptions into actual electronic design documents. Software type is not a criteria but being able to communicate effectively in English (verbal and written) and in dept understanding of technical aspects and terminology is must. Experience in compact, multilayer PCB design will be crucial and real word understanding of PCB production and assembly process will be good to have. Please apply with examples of schematics and PCB designs as reference.

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...

I am designing a solar powered light product, and would like your expertise to further development. It needs to be able to fully charge during the day by an inbuilt PV panel, and then run on that energy throughout the night. It should also be networkable through bluetooth and WiFi. The device should have a clear shell, illuminating light in all directions (similar to a light bulb), where the only exception is the solar panel mounted on top, and all electronics must be hidden inside of this facade. I am looking for both, design as well as clever electronics solutions, for this project. I have a general list of components to be used, and need PCB design and final prototype assembly and testing.

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 ...
