If you’re knee-deep in designing a new optical switch or some kinda sensor setup, you’ve probably hit that moment where you stare at the specs
If you’ve been scrambling to source BPW34S photodiodes lately, you know how frustrating it gets when stock just vanishes overnight. One day everything’s fine, next
If you’re here, chances are you’ve been working with the Vishay BPW34S for a while. It’s that trusty little PIN photodiode that’s been around forever,
So you’re knee-deep in designing an infrared optical switch, and now you’re staring at datasheets trying to figure out which 940nm phototransistor won’t let you
If you’ve been dealing with the Everlight PT334-6B in your designs, you probably know it pretty well by now. It’s that solid 5mm phototransistor that’s
If you’ve ever messed around with phototransistors in a project, you know they can stop working outta nowhere. Turns out, a lot of times its
If you’ve ever messed around with off-the-shelf phototransistors and thought, “this almost works, but if only the window filtered out more visible light” or “why
If you’ve ever wondered what makes those TV remotes work so reliably, it’s all about infrared light bouncing around invisibly. Most folks don’t think much
If you’ve ever worked around big machines in a factory, you know how quickly things can go wrong if someone’s hand gets too close to
Optical switches are pretty cool little setups that let you detect stuff without any physical contact. I’ve messed around with these a ton over the
