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.

ARDUINO-BASED CUTDOWN DEVICE FOR HIGH ALTITUDE BALLOON This project would involve designing, programming, and fabricating a finished prototype, possibly using a small single-purpose Arduino processor (i.e. Micro or Nano, or something similar) to serve as a cutdown device for a high altitude balloon. Requirements: - The device needs to be as small, lightweight, and durable as possible. - The device needs to operate using an Energizer Advanced Lithium 9-volt battery as its power source. Operation: Basically, the device would be a simple timer. - Turn on the device and a small red LED begins to flash, letting the user know that the device is active. - Turning on the device starts a 60-minute countdown. At the end of the 60-minute period, the device would activate a reed relay to allow current from the 9-volt battery to flow to a user-supplied piece of nichrome wire that would heat-up and sever a small piece of braided mason lin...

We are developing an integrated circuit board for remote data acquisition, and remote control of solid-state relays, for solar power systems in remote, off-grid healthcare facilities in sub-Saharan Africa. We call this circuitry the RMC Unit (Remote Monitor and Control). We have engaged a PCB design company to design the board. The RMC uses a variety of sensors to gather necessary data. Today. we need help in determining which sensors will be used, so that the PCB design firm can select the correct ports. Further, our in house team lacks experience in PCB design. We need someone with extensive experience who can answer questions and offer guidance. Experience developing relevant circuitry is crucial. Experience with sensors (voltage, current, and temperature) is important. As are basic programming skills. We are looking for an on-going working relationship. We expect to have further technical hurdles in the coming months for which we will need help. Feel free to contact ...
