I need a program for an Arduino board so that it can generate 4 types of PWM. 1. Sinusoidal pulse width modulation - SPWM 2. Selected harmonic elimination - SHE PWM 3. Space Vector PWM - SVPWM 4. 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 system is intented to work with a single-phase inverter. The Arduino board that will be selected will be anyone with an ATMega micropcessor. The final deliverable should be the arduino code files with extensive comment documentation.

We require a small form factor solution that satisfies the requirements listed below. We think Arduino or RaspberryPi might be the best solution, so that we can easily update code in the future, but are open to other suggestions. We will cover all parts and supplies costs. Unit must have the following hardware capabilities: - integrated speaker(s) capable of playing audio in a noisy home and still be heard. - 1/8" headphone output jack (internal speaker(s) are disabled when a device is plugged into this jack) - SD card or MicroSD card reader - built-in WiFi with ample power or antenna to provide sufficient range - power adapter connection option - user-replaceable battery powered option (we will need to determine best battery size to keep unit powered for an acceptable amount of time before battery needs replacing) Unit must have the following software capabilities: - Play audio WAV file from inserted SD card - RESTful API (read details below) The device will s...

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...

We are looking to build two versions of the PCBA with two schedules: 1. Power Only PCBA ? Take the raw DC 5V / 1.6A power from the charging unit, run it through a Boost Converter, Charge Controller, Microcontroller for LED, LED lightpipe (Bivar FLPR4.0-SBC), and other necessary inductors, etc. This version does not have a battery, protection circuit, or charge controller (for the battery). Essentially, this PCBA is a USB charger without the AC to DC conversion. 2. Power & Battery PCBA ? Requirements are attached. Everything on the Power Only PCBA with the requirements of an extra battery (1S1P protection circuit with thermistor). We own many Tenergy 30262 batteries and would like to use them. Testing: Both units must pass FCC testing and any other required testing. The battery unit must pass DOT tests. Schedule: Power Only PCBA is ASAP. Power & Battery PCBA target is end of May. Please feel free to contact me with any questions. Look forward to receiving ...

Our company is seeking a freelancer to design and build a data logging board that will be used in an exposed outdoor environment. The device should be housed in a weather tight enclosure. The enclosure will need to have a bulkhead connection in order to allow a water hose to be connected for pressure sensor readings. The device should also be capable of storing readings from a pressure sensor which detects water pressure. The readings would ideally be stored onto an SD memory card for later retrieval. The device should have an external ON / OFF switch. The device can be made using an off-the-shelf device such as an arduino if the cost is less than designing a custom printed circuit board. In summary, the device should have the following operating characteristics: -- Weather tight enclosure suitable for use in an outdoor environment -- Bulkhead connection for water pressure connection -- External ON / OFF switch -- Pressure Sensor capable of being in continuous contact with ordin...

Hello, I am needing a report created similar to the example attached, except instead of the front/top/side screenshot images, I would like there to be a single 3D model on each page that the user can spin with the mouse. I will provide the 3D models in DWG format. So they will have to be converted to 3D PDF and inserted into the report. There are approximately 20 models. Thank you, Lanny
