For my personal use, I’m looking for an electrical engineer, who can design/develop an electrical scheme. Project description: It’s some kind of Christmas tree lights, but all components (PCB, LEDs, battery, etc.) should hold inside tiny transparent ‘rod’ (enclosure). This rod needs to be as small as possible, like Dia 8 mm, and up to 40mm long. Design should include battery, charging protective components. Most component list represented on the Block scheme. Functionality: The hard part of the developing is having different lighting programs that should be changed by clicking on a switch (about 3-5 programs). It should be achieved without a microprocessor. Cheap components, small ICs. Also, I need to have calculations of how many hours it will last on one charge. Your response, please start from ‘I read’, so I’ll know that you read the whole description and have attention to details. Thank you!

Hello, I read the details and what I can say is, If using three different buttons is ok than it is pretty simple, if you want only one button, I will the circuit in a way that you need to hold the button a bit longer for each of the lighting program. It will be like 3 sec. for program 1 2 sec. for program 2 etc. still ok but only one button and the state changes each time you press on it without time differency I need to think for awhile but I am sure I will handle it. So please let me know. Regards
