Hello recruiter let me keep everything on table: 1. We want it to be very cheap. 2. We want it to be unique, unlike any aftermarket solution. My startegy: 1. We can use attiny85 microcontroller, its a very small 8 pin microcontroller, smd version is just 0.4x0.4 cm. 2. I'll use 5amp mosfet to switch led 3. Pwm signal from controller will drive the LED using Mosfet 4. According to your need push button can be wired from pcb to handle or you can intigrate the push button directly to the pcb 5. Choice of LED, i'll discuss with you, because i want the project to be out of ordinary from market solutions, you can either put 5 led 0.2 amp each or one 20watt LED, that'll be enough to blind the traffic behind the bicycle. 6. In case you want anything other than 5 settings you mentioned about brightness and switching, I'll provide you complete toolkit to reprogram the settings of LED. 7. If you want smd version of every component, the pcb can be 2cmx2cm in dimension, otherwise if you want easy to solder components that can be done too, in quite compact space. New to freelancer but have delivered 30 successful projects to our clients, you can see all the projects we delivered to our client in my portfoilio(it contains only those that i hold copyrights of)

I design Schematic and PCB on Eagle and ORCAD. I can complete your project with perfection. Hi, I am an Electrical Engineer with experience in PCB designing and Electronics circuit designing. Recently I completed one Wifi Based project(Schematic plus PCB) and one GSM based project. If you want I can show you Images of project. You are not seeing that projects on my profile because I just join one company as an Hardware Engineer and they don't allow me to take outside projects thats why I don't ask for review from my client. Please contact me so that I can show you sample of my finished projects. Reason for bad review: I completed 16 power relay project(Check it into my profile) but due to some payment issue I have to stop my project from delivery as you can see it into my profile rating. Client didn't even create milestone. At starting he agree to pay me before project delivery but after I finish the project he start avoiding my messages so this force me to stop my project from delivery. I hope you will understand. I lost 85$ in that project. Please contact me so that we can discuss.
