Hi,
I’m trying to make a strobe using the bank of leds from a cheapo flashlight. I was shooting for an on time of around 30ms but the flashes are less than overwhelming, seems very dim compared the brightness of the flashlight. Is there a ramp up with LEDs to reach full brightness that I should accommodating?
The application is to ‘freeze’ a rotating object as part of soft bearing dynamic balancer I’ve built. From an accelerometer mounted on the balancer I clean up the signal then trigger a 555 as a monostable timer setup for around 30 milliseconds. After the 555, I use a transistor as a switch. It works, just not bright enough compared to what I thought I’d get based on the flashlights brightness. Frequency will be 1-4 Herts and I want the light turned on for a short enough duration so you can see radial markings on the rotating part and thereby tell where it is its rotation when things were triggered.
I’m at the beginner end of things but try and muddle through. Maybe LEDS are a poor choice for this? I liked it because it was inexpensive, but am open to better ideas
thanks
