Hello i am looking for a hardware circuit/schematic design engineer who is very good is designing circuits/schematics. Basically i have a schematics which needs to be modified. i have one sierra wireless aircard 320U connected to the USB1 i have one TL-WN722N wireless USB adapter (wifi) connected to USB2 your tasks 1) now we will use Sierra Wireless Airprime MC7355 to be connected to mini PCIe M.2 slot hence we need to design a circuit so that host can talk to the modem on mini PCIe slot and obviously the modem must be connected to the SIM card slot. 2) and wifi must communicate with the host with some reasonable bus. in other words this usb must talk to our hardware 3) we need to add RS232 , RS485 ports to the schematics as well. Pre-requistes: please make sure you have worked on designing circuits involving sierra wireless airprime with PCIe slot and wifi as well Regards

For this job, you will be required to complete a total of 6 lab reports (Labs 4 + 6-10) and simulate digital logic circuits in a program such as Logisim ( or LogicWorks or any digital logic simulator. You must use simulation software to check your work and build schematics, saving schematic files, as well as taking screenshots of the schematics being simulated successfully. You will need to save every Logisim/simulated schematic file (.circ) as you build it while completing the steps of each procedure in each experiment and submit with a well formatted report. When submitting for review, you will send the report, the .circ file, any screenshots of a simulated circuit, and any other relevant information/data. Laboratory Experiments 1-3 and Lab 5 have already been completed. You will only need to do Experiments #4 and #6-10. View the EXAMPLE files to see how the work was done and how to set up and format properly. I have included COMPLETE examples of Labs 2, 3, and 5. You can view INCOMPLETE and possibly inaccurate Lab examples 6, 7, and 8. However, these may be incorrect results and still do not have the simulated digital circuit. The only real work is completing the questions, any calculations, and creating the schematic being simulated for the lab experiment. Skills required: Electronics, Digital Logic, Circuitry, Knowledge of Components, etc. Compensation is negotiable depending on your skills and how well you do on the reports.

I will give more details about my project after I review your application. I need a battery operated personal heating system. I also have another project that involves designing a new type of ct scanner. I really need somebody who knows about switches and junctions. Somebody who knows about virtual reality displays would be an added bonus.

Hi, I am looking for a person who can design a Circuit to control the direction of the motor driving. There is a frame which is moved by motor-1. When this frame is moving above the ground, I need to keep a safe distance from the ground. For that another motor-2 is attached on top of the frame. Based on the height from the ground this motor-2 has to lift up-or-down the frame. You can use sensors or other parts to get the distance of the frame from ground. Main matter is I need to change the safe distance parameter (some times it is 10", 12", 14"....)

A) Mechanical Constraints/Geometry Board Dimensions: The control board should meet the geometric constraints as defined. Geometry of the circuit board need to accommodate the concentric circular cut out inside the control board geometry. B) Connector for the control board Geometry: The connector can be square/rectangular in shape. The mating part for the connector can be mated with connector in only one manner/direction. The height of the connector need to be less than equal to 0.25”. If that is not achievable then the max. height should be 0.5”. Connector Availability: Readily available connector (example from Molex, 3M etc. – TBD) – choice will be dictated by cost of the connector Number of pins: 5 (4 inputs and 1 output) Alternatively: No Connector on the board with wires soldered directly to the board. How much does this impact pricing? If the number of pins increase, it would be potentially more cost effective to adopt the approach of a connector than soldered wires. C) Control Board Operation Control Voltage: 0-5 V and PWM signal. Optional: 4-20 mA signal (optional) – dip switch Total number of Inputs: 4 (Supply Voltage range (10 V-38 V), Common Ground, Control Voltage (0-5 V), Motor Direction of Rotation-F/R). Discuss:+5.0V supply from board: power supply for speed control potentiometer and so the customer does not require a separate voltage source for controls. Total number of Outputs: 1 (Tach Out) – Pulse per rev, signal options available Motor Normal Operating Current Range: 0 – 4 amps Motor Max. Current / startup current: 4.5 amps Maximum electronic component temperature (ex: driver chip): max. 125 C, TBD RPM range: 500 rpm - 4000 rpm @ given speed and given torque Feedback: Open Loop Control with selectable closed loop control (RPM fluctuations are within 1 rpm of set point, ± 1 RPM) Set point RPM Fluctuations at constant load: Within 1 rpm of set point, Tolerance ± 1 RPM Motor control scheme: 0 – 5VDC PWM control signal linearly mapped to 500-4000 RPM speed. (Discuss on Open loop and closed loop with Control Resources) D) Control Board Intelligent Protection Over current protection: The control board shuts itself down if current exceeds 4.5 amps (Optional 3.5 amps). Reset current? Over Voltage and Under Voltage Protection If speed control is not required, supply voltage can be used in lieu of control voltage. Supply voltage acts as 5 V signal (10V-38V) Thermal shutdown: Design includes thermal shutdown at 125°C. Power to be cycled after cool down below 100°C to restart Fusing: Yes E) Regulatory/Environmental Operating Pump: -20 °C to 125 °C, 95% RH EMC/EMI: To be designed with best practices RoHS Compliant: yes Safety Standards: Designed to IEC standard 60950 Assembly Standards: Built to current IPC-A-610

I'm a software guy in need of a custom Bluetooth-connected relay module. Looking for someone to do the complete hardware design, from schematic to the final PCB and BOM. I'd prefer Eagle or Kicad for the design files but am flexible on this. Some requirements: * BLE module: BM70 ( ** Flexible on this if you have other suggestions * (3) individually controlled 24vdc/0.5 Amp relays, normally open * (4) indicator LEDs, 1 power, 3 output indicators * (1) pushbutton * Tag-Connect pads for flashing * 5V input, USB Micro connector (no data) I would retain ownership of the finished design files once completed. Or if necessary, the design would fall under whatever open source licensing necessitated by the libraries used. Thanks for checking out the project!
