I'm developing a gateway station that receives data over RF from sensor-stations, and send this data to a cloud via WiFi. I need to do 2 improvements to it. On one hand, I need to control a wifi modem. turn it on and off every time the the GW sends new data to the cloud. On the other, I'm using the LM2596 as voltage regulator. It goes from the 12V supplied by a solar panel to stable 5 volts, this supplies the wifi modem and other route goes to a LDO-3.3V. I don't want to use the module () anymore and embed it to the PCB as a fixed-5V circuit. So i Ask for: 1. Add a transistor circuit to supply 5V to the modem (from the lm2596 regulator) when the ESP32's GPIO commands. Add it to the

Kijiji The following is a reply to your "PLC and Hmi programmer--own software--Servos--Control Systems" Ad on Kijiji. Jeff: Hi, I need someone to re-program an Allen Bradley micrologix 1200 I have a Single shaft RG32WP from “Vecoplan” that is using a Allen Bradley micrologix 1200 and I need to reprogram it The controller is set for 480 volts and I don't know the amperage it's set at. I changed the motors to 600 volts and the amperage becomes lower so the control is not sending the lower amp and still keeps pushing the material instead of slowing down or giving a 5 second break. Because it keeps pushing the rotor binds up can't chew fast enough then it hits the shut off switch and the machine shuts down Can anyone help Higher the vol...
