I need IC diagram that should be the backbone of a Handsfree. It should include the following modules: - Power supply module. Rechargeable batteries. They should be small enough to fit in the handsfree. I've found this model (MS621FE,   [obscured]  /attachments/solar-study/seiko.pdf) but I'm open to suggestions for others. - It should be using micro usb as source. - Red LED indication when the usb is plugged and the batteries are charging. - Green LED to indicate when the usb is still connected but the batteries are charged. The LEDs should not be lighten at the same time and should be small so they can fit in the handsfree. No LED should be on when the usb is unplugged. - Overcharge protection - This part should be designed in such a way that no harm is done to the batteries while charging and discharging. And there is absolutely no risk to the users. - Bluetooth receiver module. Other devices should be able to link to it via bluetooth. I am aiming to transfer ...

We have a spinning display (prototype) which has a 7" display, motor to spin our product and using an Olimex board to run the video / audio. We have successfully prototyped this and now, we need a freelancer to optimize this design and prepare it for manufacturing as the cost is too high using the Olimex board and the associated 7" LCD/controller board. We are using a standard microwave oven motor to independently spin our product and this is directly connected to a switch and powered directly to an AC power source. The motor turns 360 degrees and then automatically reverses since we have created a mechanical stop. The way the unit will function is as follows: 1) User will turn on a power switch located on the bottom of the display 2) Display will provide power to the motor which will start spinning and simultenously power the microcontroller board to run the OS (i.e. Linus/Android). 3) OS will initiate and the user will see a splash screen which will allow them to e...

We are using the Synapse Wireless RF200PD1 in our product. We have an order to supply our product to Japan. We need someone fully familiar with the requirements of obtaining a modular certification of the radio module in Japan, who can shepherd us through the complete process and, if necessary, help prepare the documentation. Most tasks such as preparing the module for certification testing, drawings, etc. we can do, but we need leadership to take the process from beginning to end including selecting the test laboratory, the certification house, etc. Final deliverable is the Japanese certification letter. Successful bidder will demonstrate that a similar certification has been accepted. Japanese consultants or Japanese speaking specialists preferred but not required.

We need help designing a very simple circuit, that will fit our specifications. We are trying to use the attached LED, with the attached LED driver (or an equivalent), but we don't know how to design an appropriate circuit for our specs. We want the LED to run at 18.2V and 1.2Amps. We don't need anything fancy, no PWM functionality. We just need to turn the LED on and off very quickly via a +/- 5V signal. Please see the "Shopping List" below for further requirements and specs. SHOPPING LIST: Input Power 24v dc-27v dc Battery 150AH Led Requirements 1. Build a linear array of 120 light that will be powered using a 24vdc 150 amp battery. 2. The lights will be mounted on a heat sink that will cool the lights to temperatures well below the required operating temperatures. 3. Regulate input to each led to 18.3v dc and limit amperage to 1.2 amps 4. Ability to turn light on and off 10,000 times per second for 14 micro seconds. 5. Each LED will have a dedicated driver to prevent t...

You will get a real life netlist of a combinational block (no memory elements). Your task, is using standard Python programming language Generate a new logically equivalent netlist which only uses NAND2 and NOR2 gates, which replace all the different gates that are there already.(refer block32 notepad for verilog code) Requirements: ? Code should be tidy and commented ? The code should work also on other netlists ? make it as generic as possible ? The netlist generated should be a legal verilog netlist including input, output declarations, wires, unique gate names etc. ? Tip: use a text editor that supports highlighted verilog syntax like: sublime text, Notepad++, Nedit or emacs ? Assume the drive strength to be X1 in all NOR2 an d NAND2 that you would use ? Code should be easily extended to new types of gates upon request ? i.e. when a new netlist comes with new gate types inside ? the change process should be easy

I need a program for an Arduino board so that it can generate 2 types of PWM. 1. Space Vector PWM - SVPWM 2. Hysteresis band current control PWM The user must be able to select the type of PWM that he wants and the frequency (1-200 Hz). The frequency will not be changed with a potensiometer because of the noise but from the serial monitor. The system is intented to work with a SINGLE-phase inverter. The Arduino board that will be selected will be arduino uno. The final deliverable should be the arduino code files with extensive comment documentation.
