Enlarger Timer app - DarkTimer

[peekpt]

Hi, everyone. I do some darkroom black & white printing, basically I use two filters and split grade technique. One day I decided to do a timer to help me in the process.

It's very annoying and time consuming to set up manual timers and keep track of things for split grade processing in the darkroom. The timers need to be reset at each exposure and filter change, and it usually requires the photographer to keep notes as he goes along. Darktimer is designed to simplify the process, with multiple timers and sound alerts that will allow the photographer to focus on the creative process instead of worrying about elapsed time.

The app looks really good but have you thought of taking it to the next stage where the app also controls the enlarger?

There are a couple of possibly easy and not too expensive options.

If the enlarger was plugged in to an ir remote controlled power point (available on eBay for a few dollars) then there are at least a couple of devices that could allow the app to turn the enlarger on and off.

One option would be the redeye mini https://thinkflood.com/products/redeye-mini/ that uses a dongle in the headphone socket to send ir commands and costs less than $50. I think they make a programming manual freely available.

Another slightly more expensive ($75) option might be the gear4 unity remote that receives Bluetooth commands and converts them to ir remote commands.

This looks really good. Would it be OK for me to write about it on my blog? One thing I'd like to know is if it disables the iPhone's other functions while it's in operation. The red figures might be safe as far as photo paper is concerned but if it's sitting next to the easel and the phone rings and lights up that could be a bit of a problem.
