Using the HYPNOTIZE as a general shunt reg PCB

@Salas
Yes I connect both rails + & - & only loaded the rail +

 

[Salas]

Pictures please.

An externally hosted image should be here but it was not working when we last tested it.

 

[Salas]

I see all leds lit. Is insulation OK between all Mosfets and case? Is minus side healthy?

 

[merlin el mago]

Don't lit, isn't powered, it's an effect camera flash.

Yes are isolated from chassis, you can't see because is transparent isulation.

Not, the problem is in minus rail, the 5 leds between mosfets don't lit & the 2 resistors 33 ohms 1W in parallel starting smoke, as you can see his colour is different of positive rail.

 

[Salas]

I thought they were some strange color. OK, so are the leds facing correctly? There is a guide sign. A half circle. Showing how to orient their flat side.

 

[merlin el mago]

Mines are round, yellow colour lit, when don't lit are transparents.

-D+?

Long leg + & sort leg -?

 

[Salas]

Yep. The 240's and 9240's aren't the other way around for sure? That's a board, few things to go wrong.

 

[merlin el mago]

I'm using 9140

 

[igwt]

merlin,
do you have the ground jumper between the diodes installed? from the pics it looks to be missing

 

[Salas]

I'm using 9140

But you need 140 too. And yes, the jumper is missing. Good catch igwt.

 

[Tea-Bag]

no ground reference, smoke, wrong fet type in smoke.
Done them both.

 

[Salas]

Done them both? Who gave you so many boards to experiment with?

 

[Tea-Bag]

I should mention I've done neither to these boards. But I did both to a couple of F5 boards. Have a hard time reading P vs N. Oh ya, and no ground reference for baby shunt killed that. Can't win or lose if you don't play. It's called experience right?

 

[merlin el mago]

@igwt
I didn't, thank you

@Tea-Bag
So I have to change two 9140 rail minus, anything else more?

@Salas
Do you know who's the seller....

We need one of those magnifiers with white leds on the rim. Simple tools that can help a lot. I got a 3Euro thing with pivoted braces, a couple of crocodiles at their ends and a magnifier on another brace that can be positioned around. Its very Metropolis. Can hold for you a small board to assemble. Only 3 Euro and it can save a lot of nerves.

Where it says IRFP240 you can use either that or IRFP140. On line sellers, electronics downtown shops.

PCB seller....

Only have to connect the gnd & change the two mosfets right?

 

[Salas]

As far as it shows those must be your main mistakes. Change the BBQ resistors too. PCB seller is someone Passphile.

 

[merlin el mago]

Without mistakes life will be too worried.

Ok connected gnd, it's necessary to change the 2 mosfets for rail minus?
