I think it is time to share this project that I made years ago but it is not a kind of sharing. The devil did not have an open schematic like every time :). I found time.
As understood from the circuit diagram, the CD4017 and NE555 integrations are controlled by police pinch + signal lights. Trimpots set the burning speeds.
BICYCLE FUEL CIRCUIT DIAGRAM
Res I left empty because the resistance is not an all LEDs, LEDs, and power parael connecting resistor value can be found. I did it this way. It is not really a useful method, but I do not think it will easily become difficult unless the LEDs are of poor quality.
There are bicycle horn, signal and brake light sets for the brake knob. We can check if a part of the rear brake is removed and the brake is tightened with a screwdriver.
I use a 6V 4Ah battery, and I use a smart charger
Charge can now be selected according to the battery or battery to be used.
Come on to the box. Although the drink was not very cold, I could not find another alternative then. I had supplied the box materials that appeared in the video to Karaköy and I made these drawings and drawings again with the help of the manual output. Then the plaque and LEDs were already sitting. Depending on the number of LEDs and the likelihood it can be done in different ways.
Finally, when all the LEDs are on (the signal is on one side, of course ) it draws a current of about 0.5A at 6V.
- Wide supply voltage range: 3.0V to 15V
- High noise immunity: 0.45 VDD (Typ.)
- Low power Fan out of 2 driving 74L TTL compatibility: or 1 driving 74LS
- Medium speed operation: 5.0 MHz (Typ.) with 10V VDD
- Low power: 10 µW (Typ.)
- Fully static operation
