The Power Breezer is an evaporative cooler. It has the following components: The main fan (which does what a fan does - blows air). An atomizer (a rotating disc that throws water into the main fan’s air stream). A water pump (which pumps water from a water tank onto the atomizer). A rotational motor (which swings the fan head left/right) The machine operates in the following way: Water from the main tank is pumped and thrown onto a rotating disc called an atomizer. The atomizer, despite its name, does not break down water into single atoms or molecules, but rather to very small droplets. These droplets are thrown (by the centrifugal force of the rotating disc) into the main air stream. The water droplets evaporate in the (hot) air stream, serving to cool it as well as to humidify it. You may see it in action at [login to view URL] and [login to view URL] What we require is a simple PCB that will receive the signals from the control panel (what is on, what is off, what speed should it run) and act on them: open/close the respective relays and set the correct speed of the components (generate a PWM signal for the pump). All the components (pump/motors) have external drivers (no motor drivers are needed on board). Simply choose the right components (pluggable terminal blocks, relays, PWM generator), and build it.

Its a simple but an interesting job. I will design the main control board and will assemble 5 prototypes for it. I do have in house assembling facilities with all the machinery and testing equipment required for it. I will then ship 3 boards to you for testing and keep two boards for building the firmware. My bid includes everything, designing the control board, procuring components and PCB for it, assembling as well as firmware development. There will be 3 milestones for it, 1st one when design is ready so that I can start making the PCB and procure components, 2nd milestone when the test prototype is shipped to you after validating everything works and basic firmware is ready, 3rd and final milestone will be after you test at your side and satisfied. Expected duration for completion of this job will be 45 days or less as there will be many phases and all my PCBs are nowadays being fabricated in China so there are external factors which may cause delays. However I normally get them in 10 days and parts should reach by that time from digikey or mouser. I will also assist you to program the control board just in case needed. I will however send you pre loaded firmware in them, but I am sure you will need some tweaking on the codes in order to perform at its highest efficiency once you connect that to your actual mechanism. I will tweak the codes accordingly as per your feedback and test results. Lets discuss and get it done nicely. Thanks...BR. Roy

Hello, Greetings of Peace! It was really cool to see the actual breezer in working. I love to create something worth that would be used to run such a cool device. It has really got my interest. Well, I have great experience in developing custom electronics systems. I have developed an automation for a solar thermal power plant and have created many other industrial solutions. I have the ability to give my clients the best-optimised solution with industrial standards. I love to program to control all that stuff from the video. I can give you a one-stop solution for prototyping, PCB design, assembly, and manufacture. I would like to have the opportunity to work with you and would love to discuss your requirements in detail. Please have a look at my portfolio for my detail work. https://www.freelancer.com/u/krunalbhongade.html Let's get in touch to discuss in detail. Thanks and Regards, Bk Krunal

Hi I would be very happy to help create the control pcb to help you enhance your product. I would of course require some info regarding the motors and the type of interface you would like to give - whether its mechanical switch based or a more modern capacitive touch control based. The electronics will be designed to run on a universal ac supply so you could export it anywhere and not have to worry about power conversions etc. I will produce a complete working prototype and have it mailed to you.

I have extensive experience in PCB board designing in Altium. I have made a multi layered PCB (finished product with multiple versions) Spartan FPGA based PCB with ethernet and other high speed connections including high speeds ADCs and many CMOS components were used in designing this huge product. I have a lot of experience with IOT products and embedded systems as well. I am currently designing multiple state of the art products using high tech measurement instruments such as Agilent Spectrum analyzers, oscilloscopes etc. Hence I am confident that I will give you top quality fully functional ergonomic design in minimal time

Dear Sir: Thank you very much for your polite offer about a power breezer PCB; in order to achieve your best satisfaction, we'd thank you please specify us some additional parameters about the needed circuit and its environment, as could are: -Motors to be used: kind and power for each one; Power supply: Voltage and peak current. -Level of "intelligence": speed breeze regulation, humidity level regulation, (any other one). -Alarm situations to be contemplated: Overcurrent, Overvoltage, Overtemperature, lack of water... -The PWM will be generated by the PBC; does the power drives also be incorporated to handle the motors current?. In such case, does the DC necessary to feed the PWM generators be rectified from line onboard? Thank you in advance for your answer; You can have full confidence that, if we could agree, your project will be studied with the utmost detail and carried out with earnest professionalism. Best Wishes Carlos de los Rios

I had worked on a air cooler project for BAJAJ. I had good experience in those areas. I can provide you a better solution for you . Before proceeding I would like to know about the BOM cost and physical dimension of the cob and the power requirements for pump ,motor ,I/P and O/P voltage and current requirements. I can design the project to pass all IEC standards and to EMI and EMC standard.
