    ESP8266 ESP-01 (WiFi relay module) Usage Help Request

    Hi guys. It's been a lot of time since I was last here. So, after my cellphone activated cupboard lock project (it worked, but the headache maintaining it was immeasurable) I stopped being an intrepid mad electrician and bought a proper remote relay module ESP8266 ESP-01 which they said allows...

    BJT or MOSFET for 4017 Relay Driver Circuit retaining High-Level Logic Output

    Hello there, I'll start by saying I'm by no means an expert in electronic design, so please bear with me. Also my schematic and the datasheets I'm using will all be attached to this post. I'm designing a circuit whereby the output of a 4017B IC is driving a relay via a BC337-25 BJT Transistor...

    light switch/relay box build

    Good morning; Long time away here. I am trying to build a "relay box" that simply separates the load (tow trailer lights) from the vehicle's circuits. In some circles, especially in the Chrysler/Dodge world this is called a TIPM "saver". TIPM stands for Totally Integrated Power Module and...

    unusual trailer light interface circuit

    I came across this circuit while doing a patent search for trailer lighting at Industry Canada's website, www.ic.gc.ca. I don't know if the relays ( 67, 68, 69) will work this way. By its layout, polarized relays aren't suitable. I'll modify this circuit as a stepper motor controller.
