create a custom multiplexer/switch for me

$8-15 USD / hour

In Progress
Posted about 5 years ago

$8-15 USD / hour

1) I need an electrical engineer to design a 15-bit 2-to-1 multiplexer (switch) of low voltage signals (under 5V) on my specifications. This is a general idea but I'm not an expert, so my use of terms might not be fully correct. I'll explain the objectives to you in more detail after you place a bid. This might be as simple as figuring out which standard logic chip or two to use. 2) You will have to use electronic parts available in USA or from any online store, the cheaper the better. 3) You will have to develop an efficient circuit board and produce a working prototype of the product. I'll pay for the parts. 4) You must be able to ship the prototype to USA. I'll pay for shipping. 5) When you place a bid, please explain what is your experience in this field and what similar projects you have completed. If your bid does not have this information, I will ignore it. Thank you!

Hello thank you for making this job available. This project is very closely connected to what I have been doing for the last 6 years. I have worked on the projects similar to those. In one cpecific, the requirements were to make 8-bit 2-to-1 multiplexer. I did it using a multiplexer switch, but there are various ways to do it: 1. multiplexer 2. analog switch 3. analog electronics (transistors) I can also manufacture the boards for you, since I have the electronics manufactury line. let's talk more in the messages. Best regards

I have built custom circuits before for national & international purposes, 10yr in the industry. I can show you a sample of my last project, if you’re willing to chat. Will need detailed understanding of what you’re trying to achieve so that the best pcb can be designed for you. After that I can estimate a commitment to you, and we can set milestones. Thanks.

Hi there, I have wide experience in in Hardware/PCB design and product development of more than 5 years. I did many kinds of electronic circuits and I have got great portfolio of PCBs in rigid, flex, and rigid-flex boards. High density of components and layers like 10 or more layers. Highly mixed designs with RF, processors, digital, analog and power electronics. I am currently working in IoT specifically wireless modules for developers and I worked before in a GPS device for outdoor sports. I would like to make your low voltage multiplexer with your specifications. There are different kinds of multiplexers depending on the application, power and frequency you need. I guess is for digital signal and communications. I would like to understand your needs in private and give you a better feedback and a working hours planning. I would be glad to study your development in detail if you decide to make the project with me. I am a professional engineer. Looking for the best quality and performance on my works. Kind regards, Jesus L. Netherlands, Europe

Hi, I am an electronics engineer with over 15 years of experience in designing embedded hardware for consumer and industrial hardware. I can work end to end from concept, design the hardware, work with PCB fabrication/assembly vendors here in India and ship you the tested hardware. I will forward you the exact quote from the vendor and you can pay in actual. I will also send you the complete design docs and PC application software to test the multiplexer, if you need it. I have not got an opportunity to work in Freelancer so far, but you can find my projects at Fiverr.com. Please search for srihari_ue, which is my user ID there. Let us discuss further if you are interested in my offer. Hoping to have a fruitful collaboration here with you. Thanks & Best Regards, Srihari.
