Built an f-stop enlarger timer and want honest feedback from people who actually print

[johnjones4]

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.

Been printing in the darkroom since 1980 (professionally since 1985). I'll give it a watch later this week.

I have used many timers in my day. Currently I use a Ilford cold light head on a 4x5 Beseler enlarger chassis. https://www.ilfordphoto.com/wp/wp-content/uploads/2017/06/MG500-Operating-Manual.pdf

Very cool piece. As long as you provide clear instructions I think this will be a time saver. I believe an assembled kit is best but you could offer an unassembled kit at a lower price for the DIY crowd. Good luck.
