You are tasked with building two sensor devices that are capable of detecting objects such as people and vehicles, regardless of whether said objects are in motion or not. The devices must be small and compact, not exceeding 5 inches in height, 10 inches in width, and 4 inches in length. Physical Appearance --------------------------------- The two devices must both be encased in a Matte Black hard casing capable of withstanding repeated drops from about 5 feet in the air, extreme high and low temperatures, water/rain, snow, high winds and ice. The devices and casing must resemble the form of a square, cube or rectangle and must be able to sit flat on concrete, asphalt and many other surfaces on its own. Features and Capabilities ---------------------------------- The two devices must be equipped with Wireless, Bluetooth, NFC, GPS, Flash Memory Storage, GSM connection, 3G, 4G, Ultrasonic, Camera, and battery charging capabilities. You may add more components in order in order to successfully complete this contract. The devices must be able to detect, connect, transmit and receive data to and through Wireless, Bluetooth, NFC, GSM, 3 and 4G. The devices must be able to log data such as date, time, temperature, whether it is raining, or snowing, whether rain/water, ice and snow is present, whether or not the space it is tasked to monitor is occupied, when it becomes available, and the GPS coordinates of the individual device. Each device must have a unique signature, and must be able to securely verify that it is only communicating with the other device, and or any other allowed devices based on signature, IP address, and GPS coordinates. The devices needs to be able to detect whether an object such as a vehicle or person is within 15 feet from it. The device must also be able to detect objects within a space at least 9 feet wide and 18 feet long. The device must be able to detect vehicles based on tire plates. The devices must contain Flash Memory with at least 2GB of storage space. The devices must also be able to transmit and receive requests from a web server inquiring information such as battery life, GPS coordinates, temperature, whether conditions, date, time, and whether the space being monitored is in use or not. The devices must have battery charging capabilities, and a cord that can support 120 V charging which is the US Standard. The devices must have internal battery's meant to keep the device functioning in the case the cord is not in use or functioning. Internal batteries which can be removed and replaced should be able to last a minimum of two to three days. The devices will be functioning 24 hours/7 days a week. When the space the devices are tasked with monitoring is unoccupied or motion is not detected, the devices will display a strong beam of green light (LED) that is at least 3 inches wide, can be seen from 15 feet away, but when the space is being occupied or motion is detected, a red light will appear. The devices should have at least 1 GB of Ram, and at least 80 MHz CPU although you may increase these specifications. Blueprints and documentation -------------------------------------- You are also tasked with providing detailed blueprints containing detailed information and diagrams as to how the device was assembled. The blueprint should resemble those used by manufacturers, one example/diagram is shown in the following link - You are also tasked with providing detailed documentation of the programming, and the devices functionality, etc. You must also provide information of your suppliers for and the cost of each item. The blueprints and documentation should be stored inside a flash drive and physical paper/canvas. Reimbursements ------------------------------- You will be reimbursed for component prices of the second device, flash drive, paper/canvas and the shipping costs of shipping both devices and documents if and only if the devices work to specification and the documents meet the standards and requirements set above. Should the devices not work as required or the rest of the requirements not be met, you will be responsible for absorbing the fee's. Payment --------------------------------- In your proposal, you can request a fixed or hourly payment. Due Date --------------------------------- Completion of the blueprints accompanied with a 3D animation and or model (not required) of the product may allow me to extend the due date past November 2016, into the first or second week of December. Please be aware should you accept this contract, that this project is time sensitive. If you are successful in completing this project, I may be able to rehire you for more work such as the completion of Android and IOS mobile, and smartwatch apps, smart car apps such as those in Ford and Tesla, and apps for devices such as Amazon Alexa and Googles Home.

I am currently running an i7 3770k on a Gigabyte GA-Z77X-UD4H. I am able to overclock using the motherboard's auto tuner up until 4.4ghz without any issues but I feel like the automatic settings are wrong somehow as it tends to make me stutter in games instead. At the moment playing games like WoW with my default CPU settings and no overclock tend to give me better results in terms of framerates. So, basically I need someone who can help me do a simple overclock for my CPU that can maybe be more "stable" for my gaming needs.

We have a newly designed PCB board without embedded firmware. The board has (3 x FLASH ICs, capacitive TOUCH screen, MicroSD, Ethernet, power management for battery and POE, interface for WiFi or GSM module, NFC Mifare … etc.) we’re using Renesas MCU Rx Family (RX62N) – part number R5F562N8BDBG. For embedded software, we’re using Segger RTOS and we already did build a full operating firmware for another PCB board using almost same parts (modules). However, our electronic engineer has changed the interface Pins between the MCU and the modules (NFC IC, MicroSD, IC Flash, … etc.) which is using the following interfaces (SPI, UART, I2C, and GPIO). We need to reconfigure our libraries (SPI library, UART library … etc.) to work with the new board. Because we don’t have enough SPI and I2C interfaces in the MCU, we may need to use soft SPI and I2C. the following is list of the interfaces need to be configured/written to let the firmware work with the new board: - SDRAM IC interface - MMC Memory Card IC (SPI interface) - Capacitive Touch (I2C interface) - Serial Flash IC x 3 (all in one SPI interface with chip select pin) - EPROM IC (I2C interface) - LED Driver IC - RTC IC (I2C interface) - Configure 6 UARTS to communicate with other modules. - ADC for battery level. - RFID IC (SPI Interface) - Buzzer, Relay, LED, etc. - HID IC (UART Interface) - USB Host interface - POE IC (AS1834) I2C interface
