I have a PHP script that translates MQTT data into a CSV file. This script worked perfectly when it was sourcing data from a single MQTT topic. However, I've since moved my GPS data to a separate topic and now the script is parsing data into incorrect columns. I need a skilled developer to correct this code so that the data is parsed correctly again. Key Details: - The GPS data and sensor data needs to be put into the right columns, but the specific columns are yet to be determined. This will need to be figured out based on the structure of the data. - The script currently handles multi-level MQTT topics, but the sorting and parsing needs to be adjusted to accommodate the separate GPS topic. - The task should not take long for someone with the right skills and ex...

Will drive a coil of 17mH or 34mH (thick wire on a big, 60cm bobbin) Signal should be from 0 to 50Hz Power input from line 230Vac and idealy 100-240Vac Need 2 controls: 1. for the intesity (output voltage): 0-40 volts 2. for the frequency: 0 (off) - 50Hz The control at this stage can be potentiometers, but in the near future will be controled by an MCU, so control signal should be of low voltage (e.g. 0-5 volt) There should also be a protection of the output if there is a shortcut. Based on SG3525 is a good idea.
