Hello, This is an offer to generate Gerber files as well as Bill of Materials (BOM) for the description provided. A combination of a Wireless USB 2.4 GHz or 3.45/3.5 GHz, a sun powered grid from a calculator and a battery, and a sim card with a memory of a “history book” should be inside the extension of a mite coin. See the design on the next page attached. The coin periodically would transmit a signal to the network with the transactions, and each coin is going to be distinguished by a bar code from each other. The final version of the coin needs to be sealed completely, so it is water resistant and dust proof, and the battery needs to suffice even when it is in a dark room. There should be a simple plug in to the hardware of the coin in order to program it. Programming is the second step that I would prefer to discuss once the hardware part is over unless it is a part of it. The programming language is Assembly or anything based on it like Pascal or C++ based on Assembly similar to the coin sending the key. See the design page. Coding and decoding of the sending key are based on a formula. You would provide a mock formula, and a third party will provide a different formula for security purposes. Also, I would like to a see the graph/sketch of the circuit board. Documentation will be filed afterwards unless you provide it. The price is negotiable for the initial design, and then it would be per coin based. Many thanks, Taras Zenyuk Mannequin3 Director Related videos: https://www.adafruit.com/products/700?gclid=CMGkkriXy8wCFQ9Zhgodh2cOgA

The job is about consulting for the design and implementation of this GSM-based device: https://goo.gl/PPHeDP. More specifically, the objective is to answer the following questions: 1) What hardware parts are needed to build this? 2) Is it purely hardware design, or custom software as well? 3) How does it work? Provide a schematic diagram. 4) Are there alternative ways to achieve the same result (that may be easier to implement or just buy off-the-shelf)? Deliverables: 1) Schematic diagram of the device, along with a description. 2) Hardware parts being used, external software libraries being used, as well as any custom software development that may be needed. 3) Alternative solutions that may be easier to implement, and any available plug-and-play solutions in the market. In your cover letter, please provide: 1) Your experience, 2) Estimated hours for completing the job, 3) A brief description on how you plan to complete this job (separate question).

VIDEO HUB FOR MULTIPLE VIDEO INPUT AND OUTPUT FOR EXAMPLE CVBS IN LVDS OUT LVDS REQUIRE TWO OUTPUT WITH TI FPDLINK OUT FOR EXTERNAL DISPLAY CVBS REQUIRE ONE OUTPUT FOR EXTERNAL DISPLAY CAN FOR EXTERNAL HMI TO CONTROL (USE Kinetis EA SERIES MCU WITH CAN TRASCEIVER TJA1040) USB OTG USB HOST TO READ VIDEO AUDIO DATA FROM EXTERNAL STORAGE DEVICE TO Charge Phone BLUETOOTH USING CSR BC5MM FOR SHARING AUDIO / VIDEO FROM PHONE AMPLIFIER WITH ADC / DAC FEATURES FOR LINE-IN AND LINE-OUT (OTHER DEVISE MAY USE IT FOR AUDIO AMPLIFICATION) DSP FOR PROCESSING AND SAMPLING AUDIO AUDIO DECODER FOR MP3 / AAC / AACPlus / FLAC (If No Chipset Can Satisfy All Requirement Use Software To Decode Either) VIDEO DECODER FOR MPEG-2 / MPEG-4 / / RMVB / AVI (If No Chipset Can Satisfy All Requirement Use Software To Decode Either) VIDEO SCALER TO FIT IN DIFFERENT SIZE OF EXTERNAL DISPLAY DEFAULT DISPLAY SIZE 9" # SOFTWARE REQUIREMENT 1. SYSTEM Android / MQX RTOS + QT Recommend To Use Android Because Almost Peripheral Drivers Are Done In BSP And There Are So Many Open Source Projects Can Be Used. 2. ALL AM FM BAND NEED TO ENCODE INTO CAN BUS DATA FIELD. 3. AM FM DIGITAL SIGNALS REQUIRED TO OUTPUT FOR A RECORD FROM DSP THROUGH DIGITAL I2C. THE PERIPHERAL REQUIRED TO BE PACKED INTO TUNER HAL WITH A DAEMON TO PROVIDE A SERVICE WITH AN API FOR TOP LEVEL TUNER APPLICATION USE. Reminder: 1. All Components Requires AEC-Q100 / AEC-Q101 / AEC-Q200 / ISO26262 2. When Jobs Are Done You Need To Provide: Schematic (Cadence Orcad) PCB Layout (Cadence Allegro) BOM 3. A Working Sample Prototype If You Can Not Handle It We Will Take In Charge All Material And SMT Fees But You Need To Provide The Relative Document And We Pay You When We Confirm That Everything Is OK Design Is No Problem. 4. BSP With Custom Device Driver In Tree 5. Other Source Codes For Us To Test And Modification 6. We Will Assess A Long-Term Partnership Base The Job. Once You Have Done A Great Job We Will Need You To Help Us For Rapid Prototyping And Considering R&D Project One Quarter 3 Cases.

I believe it is Arduino, at least. I need someone that can make a circuit for a prototype I have in mind. The circuit needs to be able to activate three different switches based on the time of day (and also easy to select each switch otherwise, then go back to time). I would prefer if the whole thing could fit inside a 5" x 5" x 6" enclosure, but it it cant that will be fine for the prototype. The time of day and timing for each switch needs to be easily programmed via buttons. I can give any other information you might need after contacting me.

Looking for an EE with experience in MCU, wireless communication (wifi, rf) AC and DC voltages. We currently have 3 projects that require fine tuning. All 3 projects deal with MCU + wireless + relay or solenoid. We are a group of software programmers with little MCU (or electronics) experience and looking to partner with someone who can provide on going EE advice. More details will be discussed in private. If interested please start a conversation with us.

I need someone to design an inverter circuit with smooth sinusoidal output to be used to provide 220V 50Hz signal from a 12V DC battery (similar to a car battery). A control design for the circuit will be a plus.
