Hello, we are looking to develop a countdown timer with a large digital clock. The countdown needs to countdown from 60 minutes and show minutes and seconds. We need to be able to give 3 different commands electronically sent by a potential free girl actor (please see on google images as I don't know what its called in english). 1. Reset Clock (hold clock at 60 minutes) 2. Start countdown (count down until time is either up or stopped). 3. Stop countdown (stop and show the time that is was stopped at). We will need instructions on how to set up new clocks in the future and instructions on how to put all the hardware together. Please let me know what solution you propose and how much you would charge for it. This needs to work 100% reliably. thanks, Michael

We need to design a variable speed motor to work on a turntable. This motor will need to turn the table top that has a weight of 2 kilo. On the table there will be a product that has a weight of 3 kilo so in total there is 5 kilo needed to turn. The product on top can be clay or other materials and there will be some resistance in addition to the weight as there will be a smoothing process to the clay. The voltage should support 110 - 220volt. The speed should be very slow 1 rpm per minute to a max of 15 rpm limit. We need a on and off button. I need for the full schematics as well as the wattage necessary for the motor to be able to handle this function. I need help finding a comparable motor and components in the market so I can find similar ones is necessary. The design should be able to pass CE and even UL so we need to make this safe.

PSIM Analysis and Report of Converter Schematics The project is to design a boost converter circuit and analysis report, with high efficiencies. They need to have reasonably low costs of components for specification given. I need to design a voltage controller in PSim for 6 converters where the controller parameters are checked , analyze , tuned and chosen. Matlab, Matlab toolboxes and or simulink should be used for this process. There should be closed loop voltage control design (where necessary, with PI blocks, limiters, filters, comparators, voltage sensors, voltmeters, ammeters etc.) with reasons for block use and analysis on Control design. The circuit should simulate correctly with minimal ripple and smooth outputs. For the control design, where necessary, please include a Vreferecnce, error summer, pi block, limiter and the gating signal should be appropriate with the reason for choice. I require a transfer function for the controller and converter with variable descriptions and component relation to variables in transfer function. Topologies provided as attachments 7 of them. Use these specifications, Specification 1: P=1MW; Vin = 20kV; Vout=50kV. 2-5kHZ is an example of the switching frequency that can be used for this converter unless discussed other idea with myself . Design the converters for OPTIMUM efficiency and show calculation overall efficiency with Pin and Pout Values; also design for lowest losses with reason for use of components and how they increase efficiency of reduce losses. I'm trying to do an investigation looking at installed power in the semiconductors, size of passive components, evaluation of losses in semiconductors, losses in magnetic components and overall efficiency (so I need all these results with calculations, equations and reasons for use). Require files to be saved in PSIM 9.0. If you require reference papers for assistance, I can attach them as well. Need completion in 1 day, maximum. and a start as soon as possible. The figures should be saved in the analysis as printed files not screen shots as enlarging will reduce the quality of the image. I have completed the circuits and need to check for optimum efficiency and output and operation. I require the equations to be laid out in the format shown in the template. PSIM and Matlab to be used. Will send attached file on acceptance. No time wasters please!

We are developing a device that behaves similar to a speakerphone. We have created a functioning prototype but we do not have an electronics background. We are looking to have someone examine the prototype and help redesign the internals, buttons, wiring and how things connect into specifications that could be used for manufacturing. We are also looking for someone with experience in manufacturing that could guide us from the design steps to sourcing a manufacturer for the product. We are requiring this provider to be located in the USA and sign an NDA before they can review specifications on the device. We are hoping to find someone located in the San Francisco region so that we can meet with them in person with the prototype. Ultimately, we need someone to redesign the internals of the product so that the circuitry can be created and we can create 1-3 of the devices with new electronics and internals. We are looking to work with someone who can assist with our first device as well as help design several more devices we have in mind.
