Hey Guys, I have designed a circuit.The proposed circuit, will be used for a tracking device. The device can be connected to smartphone via Bluetooth protocol. This circuit contain following sections: 1. controller: This Section contains NRF51422 microcontroller, Antenna, motor driver, LED controller. 2. Power Section: This circuit provide energy for the system. This circuit also charges a battery by solar cell. The system has 2 source of energy, rechargeable battery and a backup battery. Also rechargeable battery has an output to a USB charger. 3. GSM/GPS: this circuit can locate the device and send its data through SMS to the user, also user can communicate with device in long distances via SMS. Concerns: -Circuit Size. Since the device is really compact, size of the circuit is an important factor. -Energy Efficiency: Solar cell is the only source of energy, therefore developing a low powered system is the must. Cooperation I will provide schematic design of the...

We require the Hardware and Software Development for an IoT enabled device, which will contain: Multiple LED's, BLE (Bluetooth Low Energy), GPS (2G/GSM/3G compatible) and a Temperature Sensor. We will also need a mobile application (iPhone and Android) to control aspects of this device (LED's and to check the Temperature) over Bluetooth and then synchronise with a Wi-Fi enabled Base Station in the home. This device will also need to contain a RESTful API to talk to other devices like LIFX, Philips Hue, NEST Thermostat, etc. The device will need to have the most amount of available battery life when not in use (e.g. low-power mode). Because this is a GPS device, it will need to consume as little battery power as possible. If this is something you are interested in, please do not hesitate to show your interest and provide a quote.

Scope: An embedded system needs a software encryption for data in motion between MCUs via various data lines. Goal: To develop an encryption routine that will become an integral part of the C++ code for the embedded system. First, to review algorithms suitable for the embedded system and select one that is mathematically simple and robust to keep the burden on the MCUs light. General: The encryption is to be used between the embedded systems that are non-public, i.e., standalone. However, the system may eventually have port(s) for internet connection. Deliverables: Source code and a written report to describes the details of the math and how to implement the encryption routine into the main code. Vetting: A short video interview may be necessary. Please propose the charge rate and the time length of the project but the details may be discussed further in the interview. ** I am sorry to be blunt--"This is not a "let's try and figure out and see if it works" hobby research...

We are looking for an ambitious go getter with grit who has graduated/currently pursuing a Bachelor’s in Electrical Engineering or a similar degree. The everyday job will be to develop an innovative product that includes a micro controller, LED, sensors and other components. You’ll need to be able to choose the appropriate components, design a schematic layout, program and test firmware to accompany the micro controller, develop a PCB, and then coordinate with assemblers and manufacturers to have the product built in the most efficient way. You’ll also have the opportunity to network with other engineers, billionaire investors, and mentors from the likes of Jabil, Frog, and more who are all a part of the accelerator program!

I need to attach OV7725 camera to Leopardboard 365. I'm using RidgeRun LeopardBoard DM36x EVAL SDK https://developer.ridgerun.com/wiki/index.php/Getting_Started_Guide_for_DM368_DM365_LeopardBoard which have Linux kernel sources with ov772x drivers included. Problem is when I enable OV772x drivers in kernel it compiles and boots on Leopardboard, but don't detect a camera and don't give any error messages while booting. It looks like driver isn't really enabled. For more info on this issue you can look at my message on Leopardboard forum http://designsomething.org/leopardboard/f/33/t/1010.aspx

I need someone to tell me how to hook 2 stepper motors up to a dual stepper motor shield. I need someone to do this quickly. Here are the motors I have: http://maintextech.en.alibaba.com/product/60025636385-222759619/24BYJ_high_toque_stepper_motor_with_step_angle_for_IP_Camera.html And here is the shield: http://www.robotshop.com/en/dual-stepper-motor-driver-shield-arduino.html I need to know which wires go where. Then I will run the sample code to test it.
