Runcam Split intervalometer

thingiverse

Unfortunately the Runcam Split has no built in feature to auto shot in intervals when it is set to photo mode. So I made this little board to do this job. When it's switched on, the interval is set to 1 second. Each time you press the little button one other second is added. So, if you want to have an interval of 5 sec, you just press it 5x, if you want 10 sec intervals you press it 10x and so on. The LED on the bottom side will flash for the first 10 cycles so you can control your settings The Runcam PCB is connected through an optocoupler, so it is completele isolated from the timer PCB. Use thin wire and a small tip to carefully solder the wires to the tiny switch on the Runcam board. For wiring see the pictures. It shows just the wiring for the Runcam Split V2. For the V1 I can't say, but it should be similar. PARTLIST: -------------- 1x ATtiny13 1x 8pin IC socket 2x SMD resistor 220 Ohm (1206) 1x SMD resistor 10 kOhm (1206) 1x SMD LED (1206) 1x optocoupler PS2501 (or KB357N2T, ....) 1x tactile switch (OMRON or similar) 1x miniature slide switch Thanks to David Watts who shared this schematic and the code. To flash the code into the ATtiny13 you can use an Arduino Uno: https://create.arduino.cc/projecthub/taunoerik/programming-attiny13-with-arduino-uno-07beba The *.brd and *.sch - files are for EAGLE (if you want to redesign the PCB). The PCB layout and Arduino code are within the ZIP file. I also added two STL files for a small housing. One with holes for screws, one without (for clueing)
