Novice, built a model for a popular wargame.
I built a modular tank using magnets for multiple variants from 1 kit.
I hope to add some LEDs (max of 20 3V) & fibre optic lights on the vehicle and fibre optics for laser sights or panel lights etc.
For the fiber optics, I plan to make sealed boxes/packets with a grommet in each to allow a 3mm LED to be fitted, 1 for RGBW colours with the fiber optic cables for each colour ending inside the box/ packet. All sealed up and blacked out to stop light leakage to the main body. Probably heat shink or acrylic resin seal. I'll need 2 of these 1 for main hull lights and one for the turret for the sights.
Been looking at a 4056 USB charging board to be hidden behind a panel as a way to charge the battery pack in the main body of the vehicle battery pack.
For the battery pack, I hope to be able recycle 18650 batteries from an old laptop battery pack for the project.
I don't know where to start, how to work out what battery power I'll need, if I can step it up if needs be. I've read a badly fitted LED can burn a system out. Should I find something to protect the circuit?
Is it worthwhile buying pre soldered LEDs with resistors and leads already done?
I read that LEDs are best wired in series, I'll hope to use the magnets to transfer power between modules either to charge individual battry set ups (enough room depending on the size of the battery required, I have several batteries from rechargeable pocket items e.g. ear buds battery pack/storage) or simply to continue power to the lights running through the section (1 mag + ve, 1 mag -ve ) The space is approx 30mm x 70mm x 160mm of the top of my head, may vary 5 mm in some cases, I'll clarify if required. The LEDs are going to be fitted about the body.
The battery pack, charger, a fiber optics box, and power transfer (hopefully magnets where possible to maintain the modular set up of the model) will be in the base, the rest will involve wiring the LEDs to the various modules. Anyway thats the brief outline, please ask if I'm unclear.
