Hello, we need to fabricate Time delay timer. Please review specifications below and let us know if you can manufacture similar timer. If you can't do something close please do not offer other types of circuits, since we do not need them. We need 500 pieces. It will be used to turn on five different electrical appliances in sequence with 1/4 to 1 second delay. Specifications following: 1. Has 5 individual channel lines for connecting wires. 2. Delays for 1/4 to 1 second each channel line; Time increments can be chosen and set from 1/4, 1/2, 3/4 to1 second. 3. Operate from 110 - 120V. Once 120V power applied to timer after half of the second delay turns on first line, then after 1/2 sec turns on the second line, then after 1/2 second - third, fourth and fifth. 4. Can be combined with similar delay circuit. If connected together, after fifth line turned on power transfers to the second delay circuit board and after 1/2 second turns on first line, then after 1/2 second - second, thir...

Plan I have a home which is currently on the municipal 110 Volt power grid. It uses 28 KWs per day. I want the home to be self sufficient. ( Like a boat ) My present plan is as follows: Get a 3,000 litre propane tank and a 5,000 watt generator that runs on propane. If all i am doing is charging the batteries is a 5,000 Watt generator enough and what hardware do I need to charge the bank of batteries quickly. Set up a bank of deep cycle batteries and an inverter so I can shut off the municipal power and run the house off the batteries. I can recharge the batteries with the generator. Currently I use 28.7 KW a day. What size and how many batteries would I need ? What type hardware/ specifications would I need for the switch ( or what ever ) to connect the invertor to the main panel of the house once the municipal power is shut off at the main breaker. Plus any gauges I would need to monitor the charge level of the batteries. What gauge of electrical cable would I ne...

Hello, I need some help in some research I have been working on regarding some design and simulation in Matlab of an induction asynchronous motor. The simulation must contain the afferent state equations of the motor, the transient non-steady behaviour of the machine, nonlinear identification, skin and saturation effects, and some basic conclusion regarding the simulation, the efficiency, robustness, reliability and feasibility. I have basic knowledge of Matlab and I really want someone whom I will work closely and communicate often in order to improve my personal abilities and knowledge as well. Also, the payment may be negiociated, so that can furfill your own personal requirements.

Hi, I'm Millan in NYC. I have an ideal that I'm trying to bring to life which requires product/mechanical development, schematics, blow out views, operational functionality all of which will be submitted for patent. What's your hourly rate and do you offer a flat rate. I know you can't give a flat rate until you know what you're working on. If this is a possibility please let me know so I can send a NDA in order to discuss the project. Thanks Millan

Hello, We have code that was written for stm32f303 microcontroller in IAR and needs to be converted to code for nRF51822 in Keil. Both microcontrollers have ARM cores so lot of it is similar. The application is to interface two sensors connected via I2C port. Then logic needs to be applied to the sensor results to come up with the final result. I will provide the existing STM32 code as well as flow chart for the logic that explains what needs to be done for each sensor. The wireless communication part of the application is already implemented in firmware of the nRF51822 only the sensor interface and logic needs to be added. Also, we can provide hardware dev board if needed. The work needs to be completed in 10 days after the project is awarded.
