help me stay alive (mains)

listen:i've spent to much time reading and not enough building stuff (no time with anything 120V). i got this neat toroid and i need some suggestions on connecting it to this power cord i have. just solder and heatshrink? seems kind of weak.
also, quick dumb question: do i take this plastic wrapper stuff off the transformer? i'm pretty sure that's a no.

do i take this plastic wrapper stuff off the transformer?

no leave it on. its there for a purpose

your safety for one

no time with anything 120V. if your new to electronics. its good to have somebody nearbuy just in case you make a mistake

do you got a pic of the toroid?

travis · 20th June 2003, 04:21 AM

i've taken 4 semesters of electronics classes at college... i have to wait for next spring for the industrial electronics class though. i could totally build a gainclone on the hickock breadboards...

picture in a minute.

i should vacuum. my mom would kill me if i let you guys see that picture at 1280x1024

primaries are white and black.......build a test jig.....look on these forums before you go killing yourself and the cat....if you took "3" semesters of electronics then you should know how to hook a basic transformer....want more help from me then recite ohms Law

travis · 20th June 2003, 04:38 AM

i know what everything is. its just the physical connecting of stuff.

remember this little triangle trick thing to help kids with the algebra of ohm's law?

Code:

 V
 -
I|R

i think i'm going to buy a plug instead of just soldering the cord to the transformer.

dam this cable modem

on this one. looks like the two white wires in the black caseing are
your primaries.

the other 4 well i use a ac dc volt meter to test em. in order i would say

yellow red is one line.could be 13v 30v 12v?

orange purple is the other line.13v 30v 12v?

test em

and put a fuze on the main

travis · 20th June 2003, 04:57 AM

is that picture's size bordering on rude? i try not to forget my dial-up roots.

it says on the side of transformer"br-re/or-ye"

i know what wires to connect. i just wanted suggestions on how. physically.
i hope radioshack has female three prong thingies these days.
