    Great guy to work with. Did the job fast and never lost patience. He worked with me to develop the software without having the actual board. That was very impressive, and it shows he knows what he is doing. Good debugging skills, always stayed in touch and finished the project on time. Would definitely love to work with him in the future.

    Project Description:I have a development board with a keypad lock firmware. You need to write firmware to add a calculator and a thermometer functionality to it. A very simple project. Please only bid if you can finish this project in two weeks...

    Design electronic circuit used in a IR fluorescent sensor that modulates a laser light source at around 20khz. Flourescent light is gathered through a optical system and focused into a 16 position photodiode array. There are 16 identical photodiode amplifier filter demodulation circuits that reduce light noise and ampllfy the 20khz analog signals from the photodiodes. The 16 analog voltage amplified filtered demodulated signals feed into a digital processor PIC 32 and an algorithm is used to determine when to output a logic signal to another device (0 Vdc). The VOLTAGE gain in each of then 16 photodiode circuits can exceed 2000X and can to be automatically adjusted by the microcontroller. The board has ethernet output, .9/ 2.5ghz Zigbee wireless transmitter, and a simple 2 line LCD interface with momentary pushbutton used to stroll through menu.

    I would like to translate an old Fortran90 simulator source code into a C# program, with results displayed in a GUI rather than a text output (3D representation of grid nodes, customizable graphs, and numerical output sheets). I personally have very limited programming experience (VBA, a little Python), but am trying to learn C# for this project. My overall goal with this project is to learn how this type of simulator works and learn C#. I do not want to produce commercial software or make money from these efforts, so my time table is very open.I will have 3 goals for this project...1. Understand the simulator source code, formulas, and inputs that will be required.2. Develop a logical C# program architecture.3. Set the program up in C# to a basic level of operation.

    I am looking to establish a long-term relationship with an electrical engineer with embedded design experience for several projects. The initial project is an electronic device that embodies the following sensors/capabilities:Heart Rate - Electrocardiogram (ECG/EKG) + Respiration3 or 6 axis Accelerometer - Motion and gesture recognitionTemperature SensorOLED Display Bluetooth Low Energy (BLE)Wireless Access Point/Gateway to transfer sensor information to cloud for evaluation/illustration/etc. If the engineer believes it is possible to incorporate a GPS without suffering too much battery life, then GPS capability would be great, too. If the engineer believes it is possible to incorporate wireless charging or actually motion charging (preferred), then that would be great, too. There is at least 3 other projects which incorporate the sensors above in various other fashions. Please send me a private message with your thoughts/estimates/questions/concerns and ideas. Additional information can be provided to you at any time.

    We have a device that currently runs Arduino code (2500 lines) but is not a standard Arduino board. It is a commercial product that is based on an ATMega 1284P, 8 relays, Roving Networks Wifi, Digi Xbee, RS485, FT800 GPU, LCD and RTC. The code is getting complicated and needs to be optimized for performance, future expansion and reliability. We are looking for someone with serious guru C skills (as well as Arduino familiarity) to analyze the existing code, make suggestions on it&quot;s improvement and, if agreed, follow through on those changes. If this small project is completed satisfactorily then further, larger projects related to the same hardware are very likely.Location is not a problem but we will provide you with example hardware. Real deep down AVR and embedded coding skills are required. This device communicates with a web-app so experience with Lua and Javascript that run at that end would be great but not required.Much more work is available to the engineer who proves him/her self.

The Documentation of the serial communication protocol used for each device will be provided.Basic functions required in the app:1) Send serial command to read current temperature (just a string of characters)2) Read data from serial adapter (temperature, current setting, etc)3) Display read data on screen4) Buttons to manipulate the temperature setting (and send the associated command over serial)Design of the app is secondary to the functionality of the app at this stage. If successful, the developer may be commissioned to improve the functionality and design of the app at a later date.

    Our team needs to collect data for machine learning. We need a battery powered portable device capable of logging data from sensors to a microSD memory card, controlling two small motors, and enumerating as a USB thumb drive displaying log files when connected to PC.We need schematic design, BoM selection, board layout, and software development. The device will include gyroscope and accelerometer data, as well as audio recording. The device has two outputs, controlling low wattage (3-5W) motors. If your team can provide a complete schematic in EAGLE, we can do the board layout.A detailed statement of work (Word document) is available for interested candidates. We are looking to start immediately, but are budget-conscious (our company is un-funded, so as much as we want to pay you a lot, we can&quot;t).
