Hello. Im designing different electronics devices, mostly based on avr, arm MCUs and boards with them like arduino, stm-discovery etc. I can help you with your deal and since im new one here I can do it cheaper then anybody. I dont understand what you mean with "occupancy", but it doesnt metter ^) Can do both either homemade prototype( faster), or order PCB production and do cute one. Ofc my bid is only my work and doesnt include any additional expenses like parts, PCBs, shiping. But parts and PCBs are much-much lower then bid. And Im little busy now, can start in a week minimum and need up to 2 weeks. Plus PCB manufacturing waiting if needed.

Hi I am interested to this project. I am familiar with electronics as well as PCB design by eagle. Thanks.

Hello, My name is Stefan, and I work at a company as an Electronic Application Engineer and I believe that I can help you with your project. I can work on schematic design, provide PCB layout, BOM, also work on firmware (if needed), develop and test the prototype. (basically I can work on the entire process). I look forward to a more detailed discussion about this project, and if you could give some additional information, it would be great. Please note that price time period that I put in my bid are just preliminary, and as soon as we set the project details, I will be able to give you a better estimate. Depending on the complexity of the project, I could finish the work sooner. I appreciate communication when working as a freelancer, and I want to assure you that I will respond to your question/ ask questions regarding the projects any time when it's necessary, because I believe that good communication leads to positive results for both sides. I am not an arrogant person, and I won't bid with a large amount of money, I want to prove myself to an employer first, and then if he appreciate my work, continue in future collaborations. I look forward to hearing from you! Wish you a nice day

Hello Sir. I can do what you need with quality and reliability. Please read more about me: I'm an Electronic Engineer, working with electronics circuits (digital, analog, mixed and of power) and embedded products with microcontrollers since 1996. My work as freelancer is my only work, so I work on the projects assigned to me full time. For the PCB project I use Altium Designer 10 You will receive: - PCB project (the entire Altium project); - PCB file; - Schematic file; - Gerber files (for manufacturing); - PCB 3D modeling view. I undestood all you need and I'm ready to start. My BID includes the prototype in a bench made PCB. Shipping not includded. I am ready to answer any question you may have. I hope you choose me. After hired we can stablish a full communication using email or Skype. Regards, Leonardo Takahata

Hello, I have experience with LED lighting I have made before RGB colored flexible LED strips. I have made devices that use power LED on metal core PCBs. I have also experience in designing chargers for different type of battery and I have also design 220V FPC power supply's If you have time I will like to talk some more with you about this project More about me: I have 8 years of product design in the automotive industry. I am an expert in: - Dc - Dc converters - USB charging - accelerometers, gyroscopes - GPS and GSM - LCD Displays - LED power calculation As a Layouter I have 5 Years experience. I am an expert in : - Power Dissipation Calculation - EMC Rules - Impedance Calculation - Manufacturing Rules I have made Layout for ARM processor. Work also with BGA footprint. I have done projects even on 10 layer. So I know how to build a layer stack up. As Layout and Schematic software I am an expert in Eagle, PADs, Zuken. As Simulation software for the Schematic I used LTSpice. Thank you for your time, Have a nice day.

hello, we can do that, i prefer to make the dimmer using analog circuit or ATMEL micrcontroller device, please send me for more discussion

I have read and understand your requirements Please open chat window to discuss further.. ++++++++++++++++++++=====================================

Dear Employer, I have 5 year experience in design of wireless sensor nodes and low power smart electronic systems. I have constructed hardware for assisting several research projects and prototyping research ideas. I have worked with Atmel's and EnergyMicro's controllers and with several Arduino boards. On low power wireless I have developed nodes with 802.15.4, Bluetooth, WiFi and ANT. I have designed PCBs with Eagle Layout Editor and PADS by mentor graphics. You are most welcome to contact me in case of any further question about my qualifications or similar projects I have been involved in or to get my insight about your project. Best Regards,

I am an electronic engineer with 4 years of experience. I can provide u proof of concept schematic and pcb layouts. please contact me to discuss details

Hi, I can design for you simple electronic circuit to dim lights. I can use PWM or digital potentiometer. Also will read light sensor and act as needed (you define) I am an electronic engineer with experience of 13 years in electronic development. I can do the actual layout and provide a working prototype. I promise to be available for you and support you even after I deliver. Amir

Dear I am Electronics Engineer. I am ready for your project. I have good experience of such projects. Thanks Engr. Malik Soban

I am an electronic engineer having a professional background on cct design and simulation.I've followed analog cct design, digital cct design and power electronic cct design modules. if you go through my portfolio you can see what i've designed. i will guarantee you that you will not regret a bit on offering me this project. :)
