Hi Guys, I am stuck with MOSFET over heating issues. I really need to resolve this fast. Behind schedule and over budget. How is $100 to the first person who steers me to success? Details are here ...   [obscured]  /support/power_management/non-isolated_dcdc/f/196/p/421954/1508657#1508657 I prefer not to award this to any single person, and tie this up longer. I need suggestions / answers immediately. Once I get the circuit to work from your guidance, I can award / pay. I am hoping to find a power expert that has seen and fought this fight before, not just anyone who is tossing out random suggestions (although I would take that now)

We are working on a project that uses Raspberry Pies and currently use serial-to-usb convertors to receive serial input from 2 sources. We lack opto isolation & this is not a solution we can repeat without great effort. So instead we need a board designed that does that and is easy to add to the Raspberry Pi. Design a board that has at least 2 (serial) inputs (more = better) with opto isolation. Every incoming connection will be a copper cable pair, not your typical 9-pin serial port. We also need guidance with where to have these made, in greater numbers (500 at least). Please propose what you can create as a board (how many inputs, and don't forget to opto-isolate every input) and what your estimated size and production price board would be, based on a rough estimate of the parts used & production process cost. #THANK YOU

We have developed a new design having rf components, during the sample test stage we have noticed certain issues and looking for validation by third party rightly experienced in this. The prospective person must be having atleast 10 years experience in designing & layout and pcb and well known to RF/ESD issues. He is supposed to find the issues and then implement changes in the schematic and layout which has been done using Altium.

I need to put 3-4 components on one pcb. They are as following: 1) Using arduino pro mini (so no usb connection is needed) 2) TCS34725 color sensor, I've built prototypes using   [obscured]  /products/1334 so it should have the same functionality. 3) HM-10 or HM-11 for bluetooth communication connected to the rx/tx of the arduino 4) circuit to produce 5v from 2 AAA 1.5v batteries. This should be on a single PCB. For the project to complete, I would order the a few PCB's to be made and all the parts which you will be sent to the contractor with mail. The contractor should assemble and test and also send me an assembled unit to test with. Please quote me the cost for the PCB design and also the cost to solder all the parts on a PCB once it is made. We would work with milestones. Thanks

Hello, I am building a model train track that is approx 1 quarter of a kilometre in length, which has the attached layout. As you will see the track can be split up into 8 zones. The objective is to design a PCB that will control all of the signal lights, based on a train passing in either direction over the relays at the beginning and end of each zone. In practice if a train is in zone:1, then the beginning of zone:2 should display amber and the beginning of zone:3 a red light. The same logic will be repeated for any three zones. I would like a cost to design the PCB and specify the components from   [obscured]  -online.com/ or   [obscured]  / please. Let me know if you have any questions, Thanks, Harry
