I'm looking for someone to take my hand drawn electronic schematics and enter them into Eagle CAD. I'm a circuit designer and will specify all the necessary details, so I just need someone that can redraw my schematic. If by some chance you also can use a program called Diptrace that would be great. I've been using Diptrace which I find more user friendly than Eagle, but I know Eagle is the standard. If your proposal looks good then I will contact you and send you a sample schematic so as to get your fixed price quote. In your proposal please supply your normal hourly rate, but once I send you a certain schematic I'd like a fixed price quote. Thank you!

I have a simple, low power 555 timer based circuit that seems to work fine on a breadboard with DIP style 555 and through-hole style support components, but seems to work erratically when I create an SMD mounted version. I need an electronic circuit expert to review my design and suggest potential issues, recommendations, and calculate battery life given the current usage, etc. Contractor must be willing to sign a Contractor's NDA, at which point I will provide the circuit and information on its usage. I am looking for someone who can provide these services in 2-3 hours of billable time.

We need an interface cable designed and prototyped that will incorporate three channels of charge mode amplifiers with gain and a single channel 15W speaker amplifier. This cable will connect a device containing two piezoelectric sensors and one speaker to an existing embedded system. Currently, the embedded system connects to a slightly different device which contains a speaker and two microphones. The goal is to include the electronics in the prototype cable that will interface the new device to the existing embedded system. We would like this designed and fabricated ASAP and would like five cables made after we have tested the prototype. A non-disclosure agreement will be required to work on this project. See attachment for the requirements. Applicants should be well versed in analog circuit design and PCB layout.

I want to design a iPhone 5 Case that has slots to accept power from the following potential power cords: +iPhone 4 +Apple notebook +Regular USB +Samsung Galaxy S4 +LG G2 +Nokia Lumia 520 +HTC One I want the case to have slots for each of these cords to plug into. Each slot would be covered by a plastic fin. My hunch is for this to work, each of these slots could lead to a central charging pad (see enclosed photo of charging pad) that is sandwiched between the phone and the case (ie the charging pad is on the inside of the case). I enclosed hand drawn sketches of what I had in mind. Please pardon the chicken scratch. If you have any questions let me know. Need electrical engineer to design manufacture ready CAD for this. To apply, please send application listing experience, word 'elephant' towards the beginning of your application, and whether you think the charging pad is the best solution for this challenge. Don't do hours of research upfront to find the best solution for this a...

I would like a circuit designed to produce a current with a specific voltage, waveform, and frequency. The design will be used to build a prototype. I will request a confidentiality agreement, provided by my organization, for the project. I may request several circuit designs afterwards with slight modifications, or seek advice when assembling the circuit.

This may be a bit of a reach but?..We are looking at out sourcing our sales and estimating. We are a small electrical contracting company in need of a sales and estimating time for a limited time. We would require lead generation for our services within a two hour travel radius. We would need lead to meet calls which one of our staff would follow up on to promote our services and possible projects for quotation. Then we would need assistance with estimates using our labour rates. The estimating process would require a detailed material list that we would then send for pricing. We are active in the Residential market both new single dwelling and large multi dwelling markets as well as the photovoltaic installations primarily microFIT. We are also interested in opening other market possibilities such as fixture re-lamping or upgrades for large factories and facilities quants approximately 40-80 Fixtures per project.

Hello, I was wondering if you could create an electronic device for me? Unfortunately my knowledge of electronics is somewhat limited however; I have taken a video of the device to show what I am after.   [obscured]  /watch?v=NJKehBVTD7s Some Info: The EMP uses 10 wraps on the large coil and 100 wraps on the small coil. It uses 6 x 3.7v lipo batteries. The pulse timing can be changed via a button on the side. I would like to be able to charge the batteries from a dc jack plug. I am interested in just the PCB and components (no coil, case or batteries). I am after about 20 making for now. Would something like this be possible to make? If a pre-set chip with timings is not do-able could an alternative like a potentiometer to control the pulse timings be created? Unfortunately, I don't have a device I can send you as it was broken when it was taken apart by another company. If it makes it any easier I can call you or contact you through Skype etc. Many thanks, Robert Hetheri...

Hi I am trying to gain a deeper understanding of how a pre amplifier works. I have an operational knowledge using microphones but I would like to modify or even design my own at some point in the future. Before I get that far I would like to get some 1 hour long lessons over Skype or anything like skype covering the signal flow in a pre amplifier and how resistors, capacitors, op amps, transformers and other electronic components might change the original signal. I would also like advise on surface mount soldering and what equipment I should by for my first preamplifier. Of course this type of understanding will take a while and I would first like to start with 10x 1 hour long lessons. No pressure, I'm sure your not a teacher by trade and teaching over the internet will be hard, but I'm sure you could help my basic knowledge and become friends. My name is dennis and I live in Australia. I'm 28 years old living in Darwin with a pretty fast internet connection.
