Hi Everyone,
I am electronics illiterate for starters and I Need help to build a circuit or to contract it out. Here is the complete background of what I am doing.
I am a 1/24th scale model car builder and I have wired in head and tail lights using micro incandescent bulbs 1.2mm in parallel and using a 1.5 v battery with no problems.
PROBLEM 1 I am building a model of my 62 Chevy Impala SS and I have a motor out of a pager that I installed inside the model motor and it is actuated by either pushing the gas pedal or moving the carb linkage. I hooked it up to an adjustable resistor so the motor speeds up and slows down with the throttle. If someone has a better Idea please tell me.
THE MAIN PROBLEM I NEED HELP WITH. I need the turn signals and the brake lights to work off the same bulb if possible. I built a simple contact switch inside the steering column using the center shaft as ground and 2 separate contacts in the outer column for left or right activation. I also have a sub miniature momentary switch under the dash so when the brake peddle is pushed I have contact for the brakes.
I have very limited amount of space to hide things in and I am hoping to use some Sony lithium coin cells stacked together to power the circuit I need. Either some CR-2450's 3 vdc @500mA , (24mm dia x 5mm thick) or CR-1620's 150mA, (16mm dia x 5mm thick). I'm using one yellow bulb for each side in the front and 3 red bulbs for each side in the rear.For a total of 6 leds for the rear and 2 Leds for the front. I do not need emergency flashers so only one side will need to blink at a time. I have a dozen or so of micro-mini 1.5 mm axial leds in red, and yellow along with 33 ohm resistors and 470 ohm resistors, NOW I AM LOST.
I need a very small circuit using Surface Mount Technology and not over 3/4 of an inch square to control the Leds. I will be using 32 Gage wire to hook the board to the Leds, I can hide that wire pretty easily. The Batteries will be hidden elsewhere. I will be mounting the red leds next to the incandescent bulbs that I use for the taillights so the Leds will over power them when on and also because of lack of room The taillight len's are only .135 Dia. I was told by using diodes it is possible to isolate the circuit so it can share the ground with both turn signals and also use diodes so the brake lights will work off the same circuit but before the blinker. I have no clue if this is right so Please tell me if this is correct. If I can use the brake lights and turn signals seperatly off the same board and bulbs I'll be happy. The trunk of the model opens so I need to hide the circuit board behind the seats that is why I need it designed using surface mount devices. Hopefully this model will be entered in State and National model shows. The turn signals and brake lights will only be on for less than one hour per show and only used for demonstrations. Power loss is no problem but dependability is. I have plenty of batteries. Also everyone talks about wiring Leds in series, Can they be wired in parallel? I wired my head lights and all six taillights in parallel and hooked them to one AAA battery with no resistors and they stayed lit up for 27 hours before dimming out but those are Incandescent bulbs not Leds I have pictures of the taillight housings and trunk area if they are needed. I don't expect something for nothing Please help me.
