Make Working Prototype, PCB, Microchip, Coding, More Looking for a simple PCB Design + Coding + Sample Board + 120 Days Warranty / Support. I have already source most components (like connectors, buttons, so on). You need choose which MCU chips and so on. Make Code. Make Sample. THEN Done. -- PCB ONE -- Functions are simple. - Button 1 (Power Function. On / Off. LED On/Off). - Button 2 (Speed and Mode Function. Slow, Middle, Fast, Mode 1, Mode 2, Mode 3. Each Selection has their own LED) It is to be connected to a battery and motor. The speed functions will alter the RPM difference (PWM and duty cycle percentages) on the motor. The LED will display according to each mode selected on the Mode Function. When unit is powered off and powered on, it will begin at First Speed = Slow Speed. -- PCB TWO -- Simple PCB Battery Charger for Battery. It will have ONE input, a micro USB, 5v current, from computer USB or wall outlet charger. This PCB will have two set of two pads. One pads from battery. Other pads to PCB 3. Components to ensure will not; - Over Charge - Discharge below certain voltage amount, depending which battery is chosen after sample is done. -- PCB THREE -- This is simple double sided PCB, two pads on each side. Only function is to transfer power from front large pads to back side pad. That's it. -- PCB FOUR -- Small board with Battery Pins + 2 Pads. The pads will be used to solder a cable and connect it to PCB 1, to supply PCB 1 with power. The battery pins will only transfer power from PCB 3 (large pads). -- SAMPLE PCB FOR PCB ONE -- This sample pcb is so I can test the 7 different motors and 5 different batteries. It will have - 5 battery input - 5 input for charging each battery separately (should have proper components to ensure no over charge, or no discharge according to each battery type) - 7 motor output - Power Function - Speed and Mode Function - Should add easy way to flash the chips on sample board. Maybe USB input or some kind jumper that lets me easy flash the chips on sample pcb board. -- VERY IMPORTANT -- I do not know which RPM is best. Therefore I need make 4 different settings. Maybe we make 4 different PCB. OR if you recommend, maybe we can use a number selection jumper so no need make so many PCB. Please check the attachment for example of sample board, the sample RPM settings and so on. PLEASE WRITE you understand "PWM and Duty Cycles" so I know you read my project brief. Thanks. I WILL PAY FOR ALL SHIPPING TO YOU / FROM YOU. I expect from you the following; - Make Schematic Diagram - Build of Materials - Make sample board (breadboard or PCB, including assembly and preliminary testing) - Mail me sample board (I will pay shipping separately) - Provide gerbers, build of materials list, code on ic, pcb design file and all other files used to construct the code on the chip - 120 days warranty of bugs or support of simple write-ups or updates. What I mean by 120 days warranty or support. Say the components list has problem. Or the code has bug we originally overlooked. This is cover by warranty. By support, it will just mean some simple adjustments if we decide use different motor or battery or add/update the vibration modes. I will make 4 milestones. - Milestone 1 (20%) released when I see schematics and request for components list to be mailed to you. - Milestone 2 (25%) released after seeing test sample fully functional without bugs - Milestone 3 (25%) released after receiving all files related to the project + samples made locally & tested. - Milestone 4 (30%) released after 120 days of warranty / support coverage.

Hi, (PWM and Duty Cycles) Firstly, I have many skills that are relevant to your project, including the electronics, pcb and motor driving aspects. I'm currently doing two projects involving driving motors, one for a mixed RC application and anoter requiring precision positioning. Secondly, you have put together a magnificant project brief, congratulations! you clealy have been giving lots of thought to it. I have read the brief in some detail and had a look at the attachments. It appears you are trying to do a motor/powersupply evaluation but its purpose is not clear, superficialy and perhaps my lack of understanding, suggests this is a very hard way to achieve what you appear to need as an outcome, however what you have asked for is easily enough done. I can comply with your ist of deliverables including the 120day support period. and your milestones are reasonable.. If you wish to go further I would be happy to offer a more detailed response to your brief and chat with you about alternative appraoches. Always happy to chat. Regards and good luck with your project. James Harrison-Smith

Hi... I have 5+ years of experience in the field of electronics. I have worked on different industrial based project where my primary role was circuit designing, circuit implementation, PCB designing and programming of micro-controller. You can check out my portfolio for my work information and my qualification. Also notice that i have worked on similar project which was "Home automation where micro controller control speed of fan motor according to speed set by user remotely. I have very good experience in industrial motor controlling like MDrive NEMA series motors. You may also like to know that in one of my project GSM based security system i have implemented dual power supply concept where system was running on external power supply but if any thief cut this supply, board will automatically turn on internal battery power supply. Once external power supply is again given, it will automatically charge to some threshold level. which is required to prevent battery damage. Other than this, I have worked on more than 35 projects including chemical detection robot for pharma industry, autonomous robots, cap sense based home automation system, looms automation and many more. Expect your work done within deadline with best quality..... Please let me know any thing else you need to know in personal message and send any specific requirement if there is, so we can discuss in details.... Thank You
