We have a PCB layout job that will take an existing .pdf schematic, adjust circuit design based on red line changes (mostly deleting a few sections) and then layout a new board based on a .dxf file of the board outline that includes all critical placements. the board is approximately 4" square and will be populated with about 80 - 100 components. We will order and assemble prototype boards here in house. This job may actually be two very similar boards with the identical schematic design. We prefer the Use of Eagle as it allows the most flexibility for us.

As you know, big box stores demand very low cost electronic gadgets. Often consumers will enjoy using an electronic gadget for a few minutes, and then will discard the gadget. Dichroic lcds require voltages > 9V. 9V driver chips are expensive, and chips suitable to drive 3V TN lcds will not handle voltages greater than 5V or 6V. I want you to write up a basic BOM. After I approve BOM, you can also make the schematic and gerbers. I need you to be creative, to "put your thinking cap on", and suggest a VERY LOW COST pcba to drive a single dichroic lcd pixel off and on, like a simple flasher circuit. The precision of the timing of the flashing off and on is not important. Square wave is best but not required. Direct drive is OK, but a multiplexing rate of 16 flashes per second or 32 flashes per second reduces battery consumption substantially. If a pcba with direct drive is lower cost than a pcba with multiplexing, I would prefer a direct drive pcba. For example, in...

This is a PCB design job. And I want you to use PADS for both schematic and layout design. The PCB is a PCIe card. I'm going to use the XR17V352 (PCIe-UART bridge) for PCIe interface. And the UART will be connected to microZED module. Simply say, This is for giving PCIe interface to microZED through UART interface. I want 2 UART connection to be connected between PCIe and microZED. I can't give you more information of XR17V352 because I couldn't find a reference schematic of it. And I want you to have some knowledge about the Zynq which is the SoC on the microZED because you need to understand it how to make the UART connection. It is basically nothing but a PCIe to UART bridge circuit attaching microZED carrier to the UART interface. So I want it cost effective, i.e. 2-layer design.

I am looking for an electrical engineer to design an electrical control box for an oven. I will need detailed specifications that I can use for taking in offers for parts and/or a fully assembled control box. Delivery is a list of components and schematics for wiring. We will only be making a few of this machine at this time, so I think it would be better to use PLC:s rather than PCB:s. The box will control one motor and two heating element arrays. The motor will need adjustable speed and soft start. The motor will also work and pause in intervals. The element arrays will be controlled individually and by a common thermostat. The elements will also be controlled with a timer. The machine will need an emergency kill-switch that turns everything(motor&elements) off Attached is a schematic representation of our system and our needs

Fido is a Belgian startup looking for a talented electronic schematic designer and PCB designer that is open to help a team design the ultimate dog wearable, to be launched this year. The PCB design should take into account multiple sensors (e.g. accelerometer, gyroscope, etc.), wireless charging and radio chipsets (e.g. BTLE, Wi-Fi, etc.). The ambition is to provide the maximum of information on an as small as possible footprint. Therefore, the PCB designer should have a firm grasp on building small and compact PCB designs. The tasks will be to: 1) Review high-level product requirements and provide feedback on feasibility to the team; 2) Support in the development of the first electronic schema's; 3) Produce and iterate on PCB designs. The ideal candidate has a startup mentality and can work under tight deadlines and often with open and changing requirements. Your own interpretation and feedback is therefore matters and will greatly impact the product design and product materia...

I need someone that can write articles in the electronic industry. Specifically on Printed Circuit Boards. Topics : - PCB surface finishing techniques (OSP, HAL, Gold Plating,...). Pros and cons - How a PCB is made (describe how a 2-layer PCB is made) - Materials available for PCB manuacturing. Pros and cons - Defining temperature of soldering on a PCB (what temperature ranges are optimal depending on the material chosen. Limit it to the most common materials for eg FR-4) - PCB pooling for prototype orders. Using a pool of different projects/clients we can reduce manufacturing costs for low quantity orders. Other subjects will come. I need a 500-800 words article for the topics. Good english and good technical knowledge. Experience in electronics required.

Hi, For more info about what we do see   [obscured]   Our project shortly: We are developing a small handheld device which automatically captures the color of any surface. The colorcodes will be sent to a smartphone (IOS/Android) for viewing via Bluetooth Low Energy. We need code to set up a RS232 uart in the KEY fob that will use 9600 or 115K baud. Thesent uart text should then be sent over the BTLE link The BTLE code can be as is in the KEY fob. Do you have the skills needed for this project and would be interested to assist us? Please note that we do not need help developing a mobile app. Best regards

Need a schematic and BOM for the wiring and components for a locator system device. The heart of the system will be a microcontroller similar to an Arduino Mega connected to a NFC Reader Shield, GSM Shield, having GPS, Wi-Fi and Bluetooth connectivity. The system will include a Lithium polymer battery, charging circuit using a mini USB port to plug in an AC charger. All components are to be generic off-the-shelf to keep cost down. It is preferable to use existing Circuit designs as much as possible to shorten the debugging process. Freelancer must be able to take care of the system design, including electronic and firmware. Electronic design includes schematics, BOM and PCB layout. Firmware design includes the implementation of all the logic functions and demo A general component layout, and functions and features requirements, will be provided as a guide. Freelancer must sign an NDA and be able to complete the job in 4 days, and be immediately available for any revisions requi...

Hello, as I want to measure 2 thermocouple temperatures via BLE, i'm looking for: A TI CC2540T with two Maxim-IC MAX31855 chips, serial protocal via BLE link, SPI from CC2540T to both MAX31855. The PCB should in the end be powered via LTC3588, but this is something for the next step of development. The application is in a vibrating environ- ment, where piezos should generate enough energy. Scope of work will be Firmware for CC2540T: - reading data from both MAX31855 via SPI - sending data via serial BLE link, when command sent via same link Hardware: - prototype BLE master (serial TTL connection for ATmel C RX/TX) - prototype BLE slave with MAX31855 - schematic and board as files in Eagle format preferably The energy harvesting would be an add-on, to be quoted separately, but just when you feel comfortable enough to offer it. - LTC3588 included of the above mentioned slave board - 3.3V supply for BLE-TX every second only - piezo disks from beepers (brass-based type) a...
