Design and develop an array of LEDs that are responsive to a magnetic field

Hello 'Lucent2', This sounds like an interesting project. My bid is based on designing suitable circuitry and testing a hand built prototype. Once the design is working correctly I will produce schematics and a PCB layout from which I can generate gerber and drill data for you to manufacture the boards. If you require a different approach, please just let me know. I'm sure I can accommodate your requirements. If it makes any difference to you, I am British and a native English speaker so communication should be easy. Please look at my resume here on the freelancer site for details of my electronics history and experience. Best regards, Paul Burger

hi, i am an electrical engineer. i have expertise in embedded system design.i can help you with this project. for my quoted bid i will provide: 1) schematics 2) PCB layout 3) Firmware 4) BOM and gerber files 5) one prototype system My milestone breakdown would be as follow: 1) initial upfront 40% 2) upon completion of the Prototype before shipment. 40% (shipment cost not included) 3) when you receive the prototypes and test it fully on your end. 20% Please check my profile for my previous work experiences. let me know if you are interested in the bid so we can discuss the details further. regards

Dear Sir, We have completed Electronic projects in Freelancer.com using Ethernet, USB and RS232 communication methods using Microchip, Atmel (Arduino Platform, Atmel studio), Texas Instrument and freescale ICs. Please see our profile for more details of our past projects and current projects. We can design your circuit using low power microcontroller with LEDs controlling by PWM according to magnetic field. Hope to join your project. Contact us for more clarification on our past projects. Best Regards, Lasantha Prasad

Hello, I have been associated with Hardware design (Circuit / Electronics design), PCB design, PCB Manufacturing, Component procurement and PCB Assembling for over 7 years. I have used various CAD/EDA tools for PCB design. Would you prefer any specific EDA tool for PCB design (or) any tool is okay? Thanks & Regards, Karthik

I have 14 year experience in electronics and system designing therefore am very confident that I can do this project,following shall be the expected milestones: 1. Specification requirement document. 2. Schematics using Altium 3. Simulation of code and electronics (Where ever possible) 4. Software delivery. About my self , you can review my profile and my clients comments. Regards.

Hi, My name is Stefan Ponova, and I work at a multinational company as an application engineer. I can start the work right away, and finish very soon. 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 have some ideas for a proper solution and I think I can help you. Of course I will prototype and send you the obtained results. My bid includes the prototyping costs. So, If you'll give me a chance to take part to your work, I will respond in the same manner, handling you good quality projects, as soon as possible. I look forward to hearing from you! Wish you a nice day!

Hi, I am an experienced electrical/electronic designer who specializes in new product development. I have designed, built and tested many systems that incorporate LEDs and am very familiar with proximity switches and sensors. Based upon your description, this product can be developed within 10-14 days (dependent upon the speed of parts acquisition and delivery). I am able to get started immediately and hope to have the opportunity to work with you on this project.

Bid price includes working prototype on a single side flex PCB. I have experience with hall sensors. You have to specify the number of hall sensors and how exactly do you want them to operate - if any sensor detects magnet it powers it's led or if all sensors detect magnet they power the leds. Please be more specific and contact me if you like my offer.

Dear Client, Hope you are doing great. Thanks for the project post and providing an opportunity to bid upon. It is my immense pleasure to submit my proposal for this project as I am an experienced product designer with more than 5 years of experience. As per my understanding, the scope of this project is to design LED control unit, which is hall effect sensor. As soon as it senses some magnetic field due to placement of magnet, the LED brightness will be regulated. This device may or may not require a micro-controller. If the described function is only need, then we can do the needful using transistor based amplifier. Kindly suggest, if the device is having any LED driver. There will small number of component. I can provide you with design as per your size recommendation. The BoM will be generated with proxy sales quotations. The design step will have schematic drawn in Eagle, then converting to PCB. After that optimized routing will be done and Gerber Files will be generated. I will provide you the complete design files, which will include PCB files, Gerber files, schematic, Bill of materials, part numbers and a prototype delivered to your address through DHL. Looking forward for your kind response. I would love to give you my relevant work references. Kind regards, Amit

hi i am an electronics design engineer, I have completed a number of projects here on freelancer. you can have a detailed look at my previous works by clicking on my profile. I am highly interested in your project. Please reply to discuss it further. regards

Hello, I can design for you a prototype on flex board. I will have pure logic. no processor. Simple. It will illuminate the LEDS when magnetic field is around. It will be configurable, and you will gey fully working board. I am Electronic engineer for more than 10 yars and I can assure you satisfaction. I have proven results. Thanks,

hi ... i can design this circuit on Altium Designer 14 to produce flex PCB... i ll provide schematics PCB BOM thanks..

I will use small SMD LEDs, a product I designed as jewelry also included a Magnetic compass so that the changes were very sensitive to orientation. The bid does not include the cost of parts which normally we source from Digikey. What short of battery do you have in mind? Thanks AD

I have experience in designning analog and digital circuits. I have made a lot of kind of projects related to it and I worked with hall sensors to current's measurement. First, I would calculate the power because of the leds and then build a circuit that allows oscillate its current in a range depending of the magnetic field approaching. Considering the formula P = V.I, we can see the leds will increase or decrease their brightness when the current varies. I have a lot of skills to make this project as soon as possible for a lower price. If you really want to make sure to hire me, I can show projects made by me.
