Hello,
I want to build my own flash for macro photography and i have some questions.
1. Do you think is better to have each led controlled by a transistor (2N2222A ?)and with a capacitor attached (470uF tantal)?
2. How can i have a visual indicator(LED) that the capacitors are charged?
Any idea or guidance on this matter is welcomed.
Thank you.
