Delta Pulse

What is the resistance between the outputs (5 and9) and GND?

OK.

Nothing between output 5 and ground, shorten between 9 and ground...replacement needed i think.. If so, thats fast..brandnew component..Is there a know reason why this can b happen or just bad luck?

Check if a short circuit between the outputs of 556 and GND.If is gone, replaced with other 556th

I bought 2.1 Ah battery. This is tied to the Dp. Twice he has gone 556 likely due to the initial current is stronger. How could this problem be eliminated?

Cant measure when ic is installed. for some reason its nothing..system is switched off ....between ground/5 nothing and ground/9 variable.. I don't get this..

Hi Freedan3d

thank you very much

Nice, thx for your speedy reaction .

I allrdy chked it. Found a mistake in PR1 221 instead of 203..i placed now 223, because i have no others here around now. Funny part is, when not on and wait some short time,and switch on.. it works, but after some small time (1 minute)the power consumtion is increased with factor 10. (50Mamp)..Seems there's a bad condensor in the circuit. I'm testing it without irf740..

My English is like yours, but it works for both of us

I forgot to say that we should first check whether a short circuit between the output 556 (5 i9), then remove NE556Sorry for my bad English.

Hi all..Pretty new on this forum, but reading it daily. Great to see you all over the world busy with this project.

I'm following this for some time, and decided to follow you on your work, to make a great MD. Only problem i have right now is that my ne556 is getting hot, while without irf740.

strugling here to get this problem solved. Circuit is checked several times. I try to catch this project up and hopefully my problem is soon solved.

Maybe any idea's around? Ow, i replaced vd8 and vd9..no difference

It's a while ago, i did't electronics..(20years+)

Thx.

Question about connector

What are the correspondence points between main PCB and LCD PCB?

Sorry error

Delta pulse lcd

Will this LCD work on any delta pulse version?

Hello Freedan3d
Thanks for posting the file: "discriminator.rar".
It is complete and functional?, Or is it a demo?
thanks
Jose

thank you so much

That resistor is for lcd backlight contrast .I use a Potentiometer for it
and i used 1000uf 10v for that it is not important
