Forum rules
The DIY forum is for personal projects (things that are not for sale, not in production), info sharing, peer to peer assistance. No backdoor spamming (DIY posts that are actually advertisements for your business). No clones of in-production pedals. If you have concerns or questions, feel free to PM admin. Thanks so much!
find an LFO design, figure out what shape of wave you want for the 'flash" and use the voltage coming out of it to control an LED... can i assume you are going to control an LDR with that?
