Samsung stay clear of it

Samsung stay clear of it I have a very expensive Samsung 46 inch 3D LCD. About every thing that can be wrong with it IS wrong. As I mainly use it to watch DVD via SCART (at least that quality is acceptable) sort of learn to live with all its limitations, useless remote, bad user interface, no settings saved... no zoom on recordings, the list is endless.

Things change, and I decided to try the local cable company for a fast internet connection (Vodafone does not seem to bother anything more than GPRS 5kB /s here, deliberately throttled), and I want my servers away from godaddy.com who are copyright violating criminals, so that fast cable would allow me to run the servers back here again... saves time, reduces problems, increases quality. Now normally I watch TV via satellite, record too, so because the cable was connected yesterday, I wanted at least to check if teafee worked via that cable (the ethernet box comes next week). Plugged the cable in the Samsung TV.... Indeed teafee worked. So left the cable in. Watched a DVD today, and all sorts of RF interference and moire on the screen. Unplugged that cable (what else could it be..), and interference gone. mmm ground? Multimeter, TV is grounded on mains, cable is grounded dunno where..

2 volts difference. Scope, yes dirty AC volts 50 Hz with spikes. OK, samsung saved on an insulation transformer, I thought after so many years selling teafees they should have learned SOMETHING but no. Made a 50 Hz isulation box:

Repeated DVD play experiment RF interference still there from cable. Maybe I should have tried an attenuator.. but hey that gets me noise on analog channels. So stay clear from Samsung.

I bought a HTC Android phone, it is user friendly and nicely made, about the opposite as that S Korea shit. Now I know why N Korea wants to nuke the south, it is Samsung.

I mostly read books. Except for occasionally changing a lightbulb in the lamp by my bed, I haven't had any problems.

Yea, well, last books I bought were about financial markets. Then I was reading some magazines, C'T (German computah magazine), some electronic ones too... many years before that psychology books... before that nuclear science, before that comics... Now with internet I like to follow politics, science,' best done online with nice color pics etc.. best universities, it is all available. No need for killing anymore trees.. Those Androids are nice, you can just read the latest news with pics in bed late at night, see youtube videos too. And comics.

Does anyone know of an avalanche diode 1600V >30A which I can actually buy a small quantity of? I need 16 of them, not 100.

Finding TVS diodes that high of voltage is going to be a problem..

Are you sure they are not MOV/Varistors ?

Sure, they are for a e-stop on a magnetizer I build. We are thinking of upping the voltage to 1600V from 880V. They dump transformer reverse current when the e-stop is pushed to stop damage to the rest of the system.

Humm same problem. At 1500V operating there is just no availibility.

I read this was not a good option for avalanche dioes.

In that case,use two 800V diodes..

DigiKey has avalanch didoes up at 1600 volts. I did see some in stock there.

Those are samples and they have them in stock..

Yeah those are the ones I have, but they are out of stock on the inverted ones. I was just wondering if someone knew of another place that might have small quantities. I hate to redo all the machine work to build the rectifier out of all non-inverting type.
