It sounded perfect! No soldering, no high-speed camera needed, extremely accurate and consistent results.Coming soon: How to build your own Arduino-powered input lag meter using a photodiode! No soldering needed.
I looked and looked and couldn't find the software nor any build-guide, i'm not experienced at all with microelectronics or building circuits so an accessible guide like that would be just what i needed, specifically the no-solder part. most guides out there either required soldering or used seemingly sub-optimal parts such as slow light sensors (with response times of 16ms - 24ms) that made me unsure of a lot of the DIY projects.
Was there ever any followup on it?
