I need a design for a small rugged battery operated LED light with a wired remote tact switch. Power supply must be 3 serial LR03 - AAA. LED color must be yellow or amber. FUNCTIONALITY: Continuous light mode: Upon tact switch input >3 sec. The LED must shine with low intensity (approx. 3 lm) for 10 minutes. Intermittent light mode: Upon tact switch input <3 sec. The LED must blink with maximum intensity (approx. 20 to 40 lm) for 30seconds (100ms on / 900ms off). More details in the attached flowchart diagram. OBJECTIVES/WISHLIST: A. Minimal Costs for PCBA (Target <2 USD@10k) B. Maximum battery livetime C. Maximum luminosity D. Vibration resistent design (short battery contact interruprions) E. Single or multiple LED with lowest costs F. Programmable or preprogrammed MCU Milestones: 1. Schematic layout incl. livetime and cost calculations 2. PCB layout 3. Prototype

Hello, I have had many years experience in electronics design and product development. I also have the capacity to develop and implement electronics deigns and produce complete engineering prototypes. Regarding your project, I dont see any particular issues other then:- What sort of distance do you want between the lamp and the button? How did you want the lamp to be enclosed? Perhaps as a flat panel or could also be in a tube with a clear lens at one end. Can you quallify the 'yellow/amber' colour? There are many options. How would you want the remote button to connect to the lamp? Happy to discuss further.. Regards and good luck with your project James Harrison-Smith
