FADU F-stop Enlarger Timer App for Android

FADU F-STOP ENLARGER TIMER



The project files for the FADU F-stop Enlarger Timer have now been moved to GitHub as that is a more appropriate place to maintain the project - but read on for an overview and release...

Hi Bob
Did you ever start selling the programmed sonoff devices?
I haven't a clue doing that stuff and would love to buy a ready to go one so I can use the Android FADU timer app.

This is probably the last update for a while as it now does pretty much all it needs to do.

I might be making reprogrammed Sonoff Basic devices available on Tindie for anyone that can't reprogram them themselves and want to have a play.

Cheers, Bob.

Hi Les.

You mention setting the app to "LC Tech". Can you give a link to the relay board you bought - just to make sure we are talking about the same board.

Does the “AI-Thinker_xxxxxx” network show up on your phone? If so, you need to connect your phone to that network first before the App can talk to it.

Also, disconnect any other device from the “AI-Thinker_xxxxxx” network to avoid confusing it.

It is also possible the board you have uses different commands - hence a link to the one you bought should help identify it.

Cheers, Bob.

Hi Les.

No, I didn't go ahead with that as there did not seem any real demand and after researching it further, I found Tindie is not a particularly welcoming place for sellers outside the US - they don't have the facilities and processes in place to handle that properly.

Cheers, Bob.

Hi Bob,
Many thanks for your replies, very much appreciated!
The relay I bought through eBay at this link:

https://www.ebay.co.uk/itm/5V-12V-Se...11720742acfc0f

The relay works with the eWeLink app and switches enlarger on and off but no sign of any 'AI-Thinker...' network on phone/tablet.

I'm assuming this is the wrong relay so if you could point me to where I can buy the correct one I would appreciate it.
Kindest regards
Les

Hi Les.

Sorry, as you guessed, that board is not compatible with the app. Only the ones listed in the manual will work with it.

These types of modules can only talk to devices connected to the internet - this is not a practical option for a timer due to the delays inherent in sending commands across the internet (the Sonof devices also have this problem by default, which is why they need to be reprogrammed first).

Are you intending to switch the mains input to the enlarger or will you be switching the low-voltage output from the voltage stabilizer?

This defines which type module you need to use.

Cheers, Bob.

Hi Bob, thanks for the clarification re the relay. In answer to your question, since I've already broken into the wires between the transformer and enlarger I would want to work on the low voltage side of the power.
Again, many thanks for taking time to help me with this.
Kindest regards
Les

Hi Les.

In that case this one is the one I used when designing the app: https://www.banggood.com/5V-ESP8266-...r_warehouse=CN

It will come from China so will take a 2 to 3 weeks to reach you unfortunately. I don't see one on ebay, but Amazon has what looks like the same module: https://www.amazon.co.uk/DollaTek-2-...206252&sr=8-36 at twice the price, but UK based.

You will also need a suitable 5V power supply and a box to put it in per the manual.

Cheers, Bob.

No problem Les. If you have any further issues once it arrives, let me know.
