Updated apps posted. Changed the Loop Mode delay to seconds.
Apps updated to version 2019_006_xxx which I am calling final. Links on the Downloads page.
The latest android app is now available in the Play Store
dropControllerV3 user guide added. Link on the Downloads page.
Decided to stop adding things and concentrate on water drops. Removed the sensor connections used for high speed photography and may spin this off as a separate project using one of the newer faster Arduino compatible boards. Need to finalize the PCB
and write a user manual.
Minor update to the circuit.
I removed the GND labels from the camera and flash trigger connections as these were misleading. A couple of people had commented that they had connected these to the GND on the PCB which is incorrect. The camera and flash connections should be connected to the optocoupler only. The labels on the trigger plugs have changed to FLASH TRIGGER GND, FLASH TRIGGER VCC to show that they are the flash connection only.
Experimental Sensor Mode published. See the Sensor Mode page.
Found an issue with the circuit diagram related to auxiliary triggers. Have updated the diagrams on the V3 page.
The changes do not effect camera, flash, or valve triggers.
Finished adding flash 3 trigger
Updated the dropController V3 sketch.
Updated the Android app.
Updated the Windows App.
The new apps require a firmware upgrade on the dropController device. Please update to Sketch_2019_V3_005_01 or higher.
Made some minor changes to dropController V3 circuit diagram. The circuit has not changed only the diagram. Wanted to show the position of the optional manual valve drain switch more clearly.
Updated the Arduino sketches (V2 and V3), updated the windows app, updated the Android app.
dropController V3 and V2 now use the same Windows app and Android app. They still have different firmware/sketches though.
There have been offers for PCB design. René sent a design, Theo has a design, and Luc is working on a design.
I think the main one will be Luc’s but I will post all designs if the designer agrees.
Version 2 in no longer being developed.
I plan to update the V3 apps to make them compatible with the V2 controller and I will still fix bugs if any are found. If you are planning on building a controller please build version 3.
