Built an f-stop enlarger timer and want honest feedback

0 x Thank You

Hey everyone - I've been working on a DIY f-stop enlarger timer for my home darkroom and recently put together a 10-minute walkthrough video of it in action. I'm sharing it here because I'd genuinely love to hear what the darkroom community thinks. This is not a sales pitch. I'm still very much in the development and feedback stage, and I want to know whether this solves a real problem for other printers, what features matter most to you, what I've missed, and whether a kit or assembled version is something you'd actually want. If you have thoughts - positive, critical, or otherwise - please share them. That kind of honest input is exactly what I'm looking for at this stage.
