no work

[laurent]

hello,

my probleme, everything is correctly assembled, welded but that does not work.
The regulator warms a lot,And after 10 seconds, the condenser 100uF in burned(blown) out
I used a I used a 9v 700ma

I checked(controlled) the welds, no probléme.
I looked if a weld does not get(touch) another weld. No, no problem
I do not go you sent back(dismissed) piéces because I have déja paid a big tax of douane:35 dollards!(douane Française!!!!)

It’s a pity because this project interested me a lot

A little disappointed all the same

I had a doubt on 2 welds, but they do not raise problem. ( Red circle)

laurent,

Can you please send high quality photographs of the top and bottom of board to michael@nootropicdesign.com

I will look carefully at the device.

[Michael]

question: is your power supply center positive? That is, does it have the correct polarity?

[laurent]

yes,

I checked it before connecting.
I also checked(controlled) the voltage to be safe(

8,8v
9v

700ma

[Michael]

The 100uF capacitor may have been defective.

Now that it is gone, what happens if you connect power? Does the voltage regulator still get hot?

If your power supply outputs clean 9V, then the capacitor is not really required.

[laurent]

It is for it that I removed the condenser,
The regulator no chauufe not any more, but that does not work .
I have 9v in the regulator(on the pin)

thanks you..

I prefer to have a new ” bomb” and I indeed want to participate at the expense of port
I would send you 15 euro(20 dollards) for the transport costs

I give them to you by paypal?

PS:
I am going to try to find this problem >:D
I controlled everything twice!!And I am going to try to see where is the problem ??? ??? ??? ???

[Michael]

Thank you. I’ll send you an email….

hello,
I received the material and that works perfectly.

I made a comparison between my assembly and yours, I see no difference.

I think that a been defective constituent(component). It was not of luck.

I thank you.

Good Christmas and new Year holidays

PS:
We can modify the bomb in this way: if I cut the bad thread, the countdown of the bomb goes faster?.

And as I said it to you, I should command you 2 other “bombs” in January or February.
