Hello everyone,
A friend of mine gave me an old PSU, PCChips MXM-145TF1, previously taken apart, and I wanted to convert it into a bench power supply.
I have tried to power it up with no success. Apparently, one of the high voltage switching transistors was removed.
I would like to know if...
Yes, I like the schematic of the "Clock Controller" and I now understand how to use the contactor.
I have been thinking about it and I might even go with servo on a mount, which flips the switch on the wall, this would make the solution more portable and cheaper being able to use it to control...
So basically a more powerful relay.
What about the relay you said I should use to drive the contactor? Can't I just drive the contactor like I would a relay using a transistor connected to the uC?
So to sum it all up,
RTC definitely, I have decided to move to a PIC16f877 to have a display telling me the current time, time at witch relay is triggered and for how long.
So about the relay,
"tpetar" mentioned I should use a contactor, could you explain to me the concept of the contactor...
Hello everyone,
I have a heater at home which I want to turn on every day at 6pm for 30 minutes.
I am planning on using a PIC16f684 to control a 20A relay to turn it on.
Now my question is: Should I use an RTC (DS1307) to tell time or create a very long delay in the program (If possible)...
Now I understand, thanks!
Your story reminded me of when I was building a power supply and the mains where shorted by its metallic case...
Heart attack + big spark + all 3 bedrooms out of electricity (safety switch, thermal switch(whatever you call it in english) switched off)
Hi,
I have a question to which I couldnt find a clear answer and that is, why does a DMM have a 20a UNFUSED socket?
Why would you fuse the 200ma Max. and leave the 20a one unfused!
The DMM I have is a low end, an Unitrend UT58C, looks nice and works well but I feel kinda insecure knowing that...
Hi there,
How are you all doing?
-Circuit-
I have built a power supply using a transformer that has multiple outputs (7), ranging from 2.5v to 35v.
I use an 8 way switch to switch between the 7 available voltages and then run them through a full wave rectifier and a capacitor(10uF) to smooth...
Hello Everyone,
I want to use an HCF4017 or similar device to controll many applications by hacking a rc car to send the motor control signals to the clock input of the HCF and then change the output and so change what device im controlling with the other "joystick" in the controller.
The...
