Circuit board Design

Hi Sir i am an expert embedded system designer. I have read and understood your requirement, I am highly interested in your project. Please GIVE ME A CHANCE TO PROVE MYSELF. I believe in relations. Money is secondary thing to me. We can have a discussion on price if its an issue. Waiting for a positive response. Regards

hi, i am an electrical engineer. i have expertise in embedded system design and Matlab.i can help you with this project. 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 past experiences with PCB development to end product. we can make your design small as possible. please contact us. best regards Lasantha Prasad

Hi, Have a Great Day. We canm help you. We have our own setup for PCB manufactuering and PCB design. We will make a prototype and test it here, after sucessfull testing we will handover you the design files. Please note we will also arrange an online demo of the hardware. Please feel free to contact. Best Regards and Happy New Year in Advance. Shahbaz.

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. (autopromotion^)) This will be some small mcu, bt module and obviously mosfet for driving your latch.

I am working as Lab Engineer at FAST National University Pakistan, in Electrical Department, I have conducted the followings Labs, and also supervised Projects related to these labs. 1. Circuit Analysis and Design (Matlab & Simulink) 2. Digital Logic Design (Verilog, VHDL) 3. Computer organization & Assembly Language (8086 processor, 8051 controller) 4. Electric Machines 5. Control System Design etc. I assure you, if you assign your project to me, you surely gonna work with me in future.

Hi, I have already done similar project. And I have components to show the working prototype. And what is the electrical specification of the hinge/latch/lock? Please reply if you consider. Thanks, Sam

i am an electronic engineer with 4 years of experience. i can make this circuit using a pic microcontroller. i can write the firmware and guide you in building the circuit and the complete setup. please contact me to discuss details

Hi, I am working with various Bluetooth modules and your requirement appears relatively simple. Please confirm whether you are using Bluetooth Classic or Bluetooth BLE ( BT4.0). I would also need to know the details of the hinge/latch/lock mechanism to design the control for this. Kind regards Marc

Hello! I have experience programming in C / C + + for almost 20 years. Devices based on Arduino, I'm doing more than 3 years. I have experience writing applications "client-server" for the Arduino, writing applications to interface Arduino and Android, integration of Arduino and Processing. I have experience making "smart house" on the Arduino (arduino, php, javascript, AJAX, JSON). More, I have experience in: - making hydroponics installations on Arduino - the control system with LED lights for plants light - equipment for the reality-show "Treasure Rom" - Access Control Systems for printing equipment with RFID I am ready to write a program for Arduino and provide a complete description of the device. But In fact, I need a more detailed description of the project.

I can do this job with no problem. This bid is for designing schema, component define and future support. If you want I can also deliver a working PCB after assembly and debug for extra cost and time.

Dear sir, It so easy by arduino,I can do it for you now, Hope to HERE FROM YOU SOON, please,contact me. Regards Eng,ALY

i am a btech student and a certified CAD/CAM designer and an experienced draftsman .I am able to do this project because i have the ability to design new things and convert your needs to 3d or 2d designs with at most accuracy,ergonomics and aesthetic qualities

I have BS, MS and PhD degrees in Electrical and Electronics Engineering from one of the most reputable universities in Turkey and have 15 years of analog and microcontroller based systems design experience (both hardware and firmware) and 5 years of RF design experience. I am founder and manager of an R&D company focusing on analog and embedded systems design. Given your app, we can design a custom circuit for your it. It will utilize a Bluetooth module and an MCU. It will be more reliable, smaller, cheaper (even for low volume production), and as you mentioned, more professional looking than an Arduino-based system. Please note that: - the bid does not include app development, it will be provided by you for testing. - we will build and test a prototype but the cost of shipping, if necessary, from Turkey to your location is not included in the bid. - end-product plastic/metal casing design/molding cost is not included. However, if you can provide a drawing for the casing, we can design the board accordingly. Alternatively, we can design the casing at extra cost. - FCC/CE certifications are also not included since even only independent laboratory testing costs exceed this bid. -the requested prepayment is only for nulling the immediately taken 10% site commission. We found it necessary because of employers who disappear after awarding the project.

Hi there, Here is your experienced and professional designer. Kindly start messaging so we can discuss further details. Regards, Frike

Dear Employer, I have been working on embedded control systems for the last six years in india. I have designed various miniature products for wearable electronics right from the conceptualisation stage. I can support you in the proposed work for: 1. Functional conceptualisation 2. Small size PCB design & fabrication 3. Embedded software development 4. Packaging of electronics I have done similar work for another employer on freelancer earlier. Please drop off your message if we can take it further :)

Hi, your requirements are relatively simple. You can use a small servo motor, a motor controller board, an MCU dev board and a Bluetooth module for your application. Since you can program yourself, there should be no issue to make connections for those components. Thank you.
