Hi, We have a schematic and library parts modeled in Eagle CAD. We need a designer to prepare our prototype board by designing the board to the schematic. You must know and have demonstrated: -Differential Pair routing, length matching within 5mils properly locating AC coupling Capacitors and ESD components (all components are specified by the schematic) -Locating silkscreens for ease of assembly -4 layer PCB routing. 2 layer is preferred however 4 layer may be used if absolutely necessary. -understanding of current limitations on trace widths -understanding DRC and specifying the correct rules for our given PCB manufacturer capabilities -run length-free-ri for matched pair evaluation We want to get this board designed within a week and considering the schematic is already available in Eagle with library parts modeled we expect this project to be maximum 15 hours of work. Please let us know your availability and when you believe you could finish this type of project.

I want a driver to run 6 of these 24volt LED white light strips driven from a single power source. http://store.yujiintl.com/collections/high-cri-led-strips-ribbon/products/bc-series-dual-cct-ribbon-120led-2835?variant=3149575809 First see this video on driving a similar strip, https://youtu.be/jLia59KfkSw?t=1m32s Use voltage regulation NOT PWM, I need to use this light with slow motion and cannot have pulsing as happens with current lights I have. There should be 2 dials, one for brightness, one for color tone balance between the 2 color channels strips (warm and cool white) and 2 switches for turning on/off each side. 1 power cord. 2 cords to connect the lights.

Use the given CAD plans as an xref base plan for MEP notes Everything you have previously received for livingston, please delete. we will go back to the ALF building after the post acute CAD drawings are finished for initial review for the tradesmen. I will only have one day before the meeting. you will have 2 by the time you awake. I will highlight what sheets on the PDF you are to focus on. the rest will be delegated to other draftsmen. Keep in mind, this is only a rough draft getting prepared for monday. Don't over think what is needed or missing. Simply place mechanicals where you see fit in accordance with the PDF mark ups.

Hi, I am looking to make this possible. I need an on/off switch for an electrical project using mosfets. Two in parallel, so is should handle 100A continuously and 300A peak or more. Size: 40x32mm Current cont: 100A Current peak: 300A Voltage: 14V - 55V (4S to 12S) Price: about 10€ for the PCB and components. http://s24.postimg.org/bkp7eufpx/Spark_Protection_Switch_F_3_D.png http://s2.postimg.org/q4ibbk8ex/Spark_Protection_Switch_B_3_D.png http://s3.postimg.org/8w5bhyfdf/Spark_Protection_Switch_Sch.png Details are here https://github.com/vedderb/SparkSwitch I simply just need help in making this a complete project. Project Details 1. Create a PCB which can use an LED switch. http://www.ebay.com/itm/20PCS-Led-Dot-Light-12V-Car-Auto-Boat-Round-Rocker-ON-OFF-Toggle-SPST-Switch-/171659787329 2. The on/off switch will be in between a 12S LiPo pack and an ESC Speed Controller. The on/off switch will turn the system on & off. 3. PCB would need to be made. Might already be made from the...

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...
