Re: NTC thermistor Temp sensor

Learning different ways of doing something does not hurt but rather equips you with allot of info some of which can be used to solve other problems @ hand in another application. I love it when a solution is looked at in different ways in that way, you even get to choose which is better,simple and m...

Re: Dc voltmeter 0-55v

Here is the link to the RC snubber circuit design. Here am interested in the LR (load resistance) is it for the transformer or the battery to be charged? https://m.youtube.com/watch?v=eZwJgPd7_p4&t=479s

Re: RTD temperature Reading

Sorry some pictures have repeatedly appeared but definitely no doubt this will work am only thinking of phase angle charging have you checked on my pics in the Dc voltmeter 0-55v post? Gonna have to post there the link to the video of the thyristor RC snuber circuit i ask you kindly to watch it.

So on the 18F47K40, i have allot of space in that I've changed allot on the display a...

Re: Dc voltmeter 0-55v

Ok am almost finishing this one but also needs the 18f47k40 because it will have a bunch of setups as i need it to be used from 12v to 48v,so with multi function two buttons i think i will be able to achieve that, may be provide a little pass code before you jump into the settings for battery to be ...

Ok, i can't run the previous code ether, because i have used a 12MHz crystal on my PCB giving me 48MHz and the max of 18f442 is 40MHz.

Re: RTD temperature Reading

For enclosure, that LCD is removable and can be put on a LCD bessel mounted on the box cover then run connector wires from the LCD in the bessel to the lcd female header on the control board.

Re: RTD temperature Reading

More i added the two Blinky leds to give a feel of a second, tick-tack and also to indicate a few on-goings coz most of it is indicated on the LCD.The buttons are DOWN, SELECT, RESET, ENTER and UP buttons from your left hand.

Re: RTD temperature Reading

The control board is almost done, am saying almost because you cannot get a pic18f47k40 here in Uganda which is the main target for this project test, same thing for the pt100.
