I want to buy a signal light for my bike but all of them don't work in real life. So I made it and want to share with you.
I bought 2 of these bike lights only $1 per set in my local store. One for front and the other one for rear. Come with 7 flash modes. But use only 1 push switch which hard to use in real life. I removed the print circuit. Keep only case and bright 5mm LEDs.
This is the test circuit. By the way, the turning switch should be 3 positions. I will draw the final circuit soon.
