OVERVIEW I have a schematic diagram for a electronic stimulation system, meant for applying electric fields to different types of materials ranging from liquids to soils. The implementation is very simple, consisting of an 5V Arduino pro-mini module, with 3 different pin outputs going to a connector. Each output is different. One puts out 5V, another does 3V via a voltage divider, and the last one has a RC filter on one of the PWM ports. I also have 4 LEDs, 2 switches, a CdS light sensor and a power jack. I developed the schematic myself along with some help from some engineering mentors, but need help with validating portions of the design, namely the current buffer and ESD protection stages. I also need to make some minor changes to the board, e.g. Adding a push button. DESIGN When I prototyped the buffer output using a Npn current-follower, I couldn't see my source waveform showing up on my scope. Maybe I made a measuring mistake, but need validation from someone more ski...

Hello, I am in need of some updates to be made to an existing Arduino-compatible PCB layout. The original layout uses all PTH components. These are being used for elementary education student courses, and I've found that it is too overwhelming for the students to have to populate the entire PTH PCB. So, I would like to have the layout modified so that some of the "less interesting" components (according to the students, which happen to be mostly the passives) are modified to SMT, leaving a few of the "more interesting" components (I/O, power, and MCU) as PTH for the students to populate themselves. The students will receive the boards with the SMT's pre-populated. For this job, I will provide the Eagle files (both schematic and layout), a revised BOM with the suggested SMT replacement components, and stenciling logo change. There are a total of 11 components that will need to be converted to SMT pads and the traces adjusted accordingly. The BOM is a draft, s...

This posting is for the delivery of a schematic and PCB design and layout of a 40W, 110V, 60Hz sine wave inverter. This includes design documentation and all files (GERBER, etc) required to manufacture and modify the design in the future. The incoming power will be from four of the attached lithium-ion batteries, arranged in a 4S configuration, which are already regulated to a 4.1V maximum charge by another circuit. Therefore, maximum input for the inverter circuit will be 16.4Vdc. Circuit size should be no more than 3x2x1" (LxWxH), and the smaller the better in all cases. Height is of highest concern, but overall size should be as compact as possible. The inverter will be in an IP56 minimum container, so heat generation is an issue to be mindful of - heatsinking to the outside is possible, but a design that generates little-to-no heat is ideal, and should be possible with this low of wattage. Audible noise should be non-existent - transformer selection should be of high quali...

We are looking for a circuit board designer to layout boards from schematic, parts list (BOM) and dimensional requirements. These designs consist of surface mount components with some through-hole parts. Generally the board designs are 4 layer (which includes internal power and ground planes). We need the design in CADSoft EaglePCB format. Layout would include final CAM files for all layers. These designs are mixed signal. This work would be on-going for new products as they are developed.

The project is to convert an Express PCB design into PADS by redrawing. I have the PCB express files as well as printed copies of the same. We use PADS Layout and PADS Logic and would like the new files created in the same platform. I will attach the Express PCB files for review in the free tool downloadable from ExpressPCB.

I'm running four 'tests' of a PCB design software for marketing purposes (we are producing marketing documents from this). The first part of the 'test' consists of building a part and finding parts in the library. The second part is doing a full schematic and then layout of a board. And the third test is a review/edit of a board (basically looking at the workflow of each type of software). In total, I expect we'll need 4 to 8 hours for each of the types of software. TASK: I need someone who is experienced in each of the four types of software, and I am assuming this is going to be four different people. Though it would be fine to have one person who knows more than one type of software. For this I need someone who is experienced in: 1. KiCAD 2. EAGLE 3. Cadence OrCAD 4. Mentor Graphics Xpedition (DxDesigner) TIMELINE: Ideally we could complete these 'tests' on or around April 16th and 17th. If you can please apply with 1. what type of software you are familiar with 2. how man...

Design a fully functional custom printed circuit board (PCB) to be used with Intel Edison(r) compute module (  [obscured]  /content/  [obscured]  /en/do-it-yourself/edison.html). Both the board and the module would preferably be powered using a single Micro USB type B receptacle (similar to the official Intel Edison(r) Mini Breakout board) connected to a power-path management IC like the TI BQ24074 or similar. The board should also contain a RJ45 Ethernet receptacle connected to a Microchip LAN9500A (or alternatively LAN9512) Ethernet-to-USB chip and Microchip 24AA02E48 EUI-48 EEPROM chip, which would provide unique MAC address to the Ethernet interface. In addition, the board should have pin headers for reset switch and status LEDs. UPDATE: I added a draft of possible circuit board layout design. The final design doesn't need to be exactly as in the image, but it hopefully gives you a better idea of what I am looking for. - I have no hardware design experience so I am dependant on y...
