DIY Enlarger Timer Circuit?

That is a mighty fine piece of work- I hope it serves you very well.

I might just build a SS timer myself, I'm sure I have everything I need in stock but it's been a while since I took out the soldering iron-

How about going the f/stop timer route?

Does it have a metronome?

flow soldered.. got access to fabrication facility with day job.

it's an f stop timer.. and I guess I can write a routine for the metronome that someone asked for.. don't see the point since it a fully programmed f stop timer..

I'm currently working on the routines for burning in..

works in 2 modes..

basic count down timer

strip mode count down.

only counts in f stops..
hex display to show the time counting down..

i also need the hex display for my other project which is a garden irrigation timer for my rose propagator....

putting the unit through it paces now.. got some software bugs to fix , otherwise working quite nicely ..

I love F Stop printing.. it really has changed the way i work in the darkroom. It's just so logical..
