Seeking an experienced electrical engineer or technician to redesign a 42A LT3751 charging circuit for use in a prototype board. Possibility of work on more extensive full production circuit if design is good. Required: Experience working in Eagle, experience with LTSpice simulation software, strong background in DC-DC flyback converters, capacitor charge controller operation. Preferred: Electrical engineering degree

Details will be sent to you once I receive notice of your interest. However the basic idea is this the pcb is large size 1220mm X 550mm. The main pattern on the board will be alternation horizontal sinusoidal or triangular patterns. each pattern will be connected to either positive polarity or negative polarity. The patterns will be routed such that a positive and negative tracks alternate from the top of the board to the bottom. Essentially ( not absolutely) no components exist on the board, only the positive and negative sinusoidal/triangular/ or straight copper tracks. More details later

Looking for someone with experience in PCB design and ordering of assembled PCBs (e.g., from 4pcb). I'm a grad student working in optics and am using an LED array to do "Fourier Ptychography" (an imaging technique that allows for simultaneous high resolution and high field of view imaging). My group has been using LED arrays like these from Adafruit (https://www.adafruit.com/products/1487, https://www.adafruit.com/products/2026) but we'd really like to use an array with closer LED spacing and brighter LEDs. My original plan was to modify the schematics/board files myself and have someone proof it before sending it to Colorado (or wherever) for fabrication/assembly, but after some thought I think it would be better just to hire someone to do the modification/proofing end-to-end (I don't trust myself not to make a mistake somewhere). Anyways, what I would like done is: 1. Modify the attached schematic files (Adafruit_NeoMatrix_8x8 v2.sch) by replacing the current LED's (WS2812/SK6812; they actually have a built-in controller IC as well) with the smaller form-factor SK6812mini. I have attached a library that has the footprint of the SK6812mini already included which you are welcome to use (pimoroni-optoelectronics.lbr). If you prefer to draw up your own part based on the specs, they are attached as well (SK6812MINI_REV.01-1-2.pdf). 2. Modify the board layout (Adafruit_NeoMatrix_8x8 v2.brd) to pack the LEDs as closely as possible. Ideally I would like something spaced at around 4.0mm or less, but if that's not possible (I realize that the SK6812mini is already 3.5mmx3.7mm), please try to get the spacing as close to 4.0mm as possible (spacing needs to be uniform for this project but perhaps not for future ones). 3. Deliverables are: schematic/board files, BOM, drill files. Basically I just want to be able to go to 4PCB (or some place) with the files and order materials and have them fabricate/assemble the board. **If you can do fabrication/assembly yourself I would be willing to pay extra for that as well. **Also, in addition to financial compensation, I would be happy to put your name on any publications of mine that end up using this device. **If this project goes well, I would probably love to get your help again for designing other LED array layouts (e.g., more rows/columns, or unequal spacing between LEDs). Thanks! Justin

Looking for an analog circuit designer to improve current schematic design and create an Eagle PCB file for a simple rechargeable BLE bracelet with a switch (no accelerometers, heart rate sensors, etc., only a BLE module, switch, and rechargable IC with battery). The project and further use will be explained upon application. This is a one time job as of right now. Applicant should be experienced with analog circuit design and be familiar with most recent releases in components for wearables.

We are looking for someone able to imagine, calculate, design and build a mtoherboard for an Automated Hyroponics project. The circuit should implement the functions described in the attached diagram. We see this project as a 6 months full time project. We can work with a set of 5 deliveries 1. Circuit design (we would like it in Fritzing, if not, in Eagle) 2. Building 4 prototypes (and shipping 3 of them to us for tests) 3. Working with our Python developer to connect electronics, sensors and actuators with Python software 4. Document things so that we are able to send a request to a PCB company and print 10 or 100 or 1000. 5. Adjust things after the feedback of the bio-engineer and the Python programmer who are at the input and the output of this curcuit.

This project is to create a schematic of a USB Powerbank that uses typical Li-Po battery (max 1000 mAh). The PCB size and shape has already been determined and layout will need to be designed to fit on that board (both sides if needed). Will need to conform to Apple's MFi regulations. Project will need to be designed in Eagle and provide all files including packaged Gerber files upon completion. A similar board can be found here for example: https://www.adafruit.com/product/2465 I will provide .dxf of the board layout when project begins. Would like a quick turnaround. Thanks for considering.

1. around 300 words, 2. theme is about solutions to solve the problems in pcb designing or PCB assembly, it should list the common problems in pcb design OR PCB Assembly, and measures to solve or avoid them 3, each article should include 1~3 pictures to better explain the subject pictures should not be download from web, should be your own PCB layout picture or other pcb picture, it can be just a screenshot which helps explain what you want to say 4. it should have a proper title. 5. 100% pass copyscape. http://copyscape.com/
