We have designed a wireless light dimmer which is working well however we wish to simplify the circuit and reduce the number of parts to decrease the costs involved with assembly. We do not mind spending more on parts. We will provide further details including the current schematic and BOM upon awarding you the job. We require this work to be carried out quickly (1-3 days). It is preferred if you can use Eagle PCB to design the schematic but we will accept Altium. No board layout is required at this stage.

Hello, I have been associated with Hardware design (Circuit / Electronics design), PCB design, PCB Manufacturing, Component procurement, PCB Assembling and Functional testing for over 9 years. I have used various CAD/EDA tools for PCB design. I'm having good experience in Eagle and Altium. I will provide the PCB Manufacturing, Component procurement, PCB Assembling & Functional testing services too. I would like to take this up and are fully equipped to deliver the required files. 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! Thanks & Regards, Karthik

Hello, Have a nice day. My name is Shahbaz Ali. iam running a setup for prototyping electronic devices. We will deliver the tested schematics. The test will be based on simulation that we will perform at our end. From the attached file i have seen 2 MOSFETS driving an AC Load. Here i would like to offer an alternate if you can accept. 1) use Optocoupler. 2) use Triac instead of using MOSFETS. The circuit can be triggered from 2.8VDC ~5VDC. for more information please feel free to contact. Best Regards, Shahbaz.

I can find you a mosfet no problem that will work in your configuration. And it will be able to work at 3.3v to be driven by a pic microcontroller you may want to put a diode in there in order for protection or some sort of isolation if you are going to use a mains line to connect to.

Do you want reduce the number of components and you need test functionality. can you send me complete details of the circuit and BOM which you are using. cost required for how many numbers? I am using Altium Design software. Already i have worked on dimming circuit. I have little bit experiance on it.

The driver will be modified according to your requirement, The driver circuit can also be provided with isolation, keeping in mind your are driving mains directly from microcontroller. I have hands on experience of power electronics specially MOSFETs and IGBTs. I have done projects like. 1 -DC Servo Motors Drives 2 - AC Servo Motor Drives which requires extensive knowledge of Power electronics, driver circuitry(like Boot Straps), Sensors, and isolation of digital and power circuits. I am looking forward to hearing from you. Hussain Aftab

Hello, I do my work in Altium, so for the schematic stage I hope it won't be a problem. It looks to be a small circuit so few days should be enough. Regards
