awful

2018-01-30 22:07:31 UTC  

wait wtf

2018-01-30 22:07:56 UTC  

AC/DC adaptor

2018-01-30 22:08:10 UTC  

interface says AC18V in

2018-01-30 22:08:12 UTC  

which is it

2018-01-30 22:12:59 UTC  

DC

2018-01-30 22:13:09 UTC  

i don't see a full bridge rectifier in there

2018-01-30 22:13:58 UTC  

this board looks like it was part of a hobbiest kit

2018-01-30 22:14:03 UTC  

so much wasted space

2018-01-30 22:14:34 UTC  

and every part is silkscreened

2018-01-30 22:15:09 UTC  

Is there nothing on the backside? Else what spaqin said

2018-01-30 22:15:24 UTC  

nothing besides traces and joints

I think it's halfwave rectifying by the looks of it

2018-01-30 22:18:16 UTC  

it uses a barrel plug as input

2018-01-30 22:18:29 UTC  

lick the caps

2018-01-30 22:18:31 UTC  

omg

2018-01-30 22:18:47 UTC  

Hrmm

2018-01-30 22:18:56 UTC  

that diode may be just for safety

2018-01-30 22:18:57 UTC  

Might be a voltage doubler from the look of the diodes?

2018-01-30 22:19:04 UTC  

in case someone plugs in a musical instrument adapter

2018-01-30 22:19:32 UTC  

And TIP122 with the zener as a reference for a cheapo linreg maybe

2018-01-30 22:19:36 UTC  

Too tired to trace that out

2018-01-30 22:19:37 UTC  

why are these traces so BIG

2018-01-30 22:19:44 UTC  

THICC traces save lives

2018-01-30 22:19:44 UTC  

big voltage fam

2018-01-30 22:19:48 UTC  

ya

2018-01-30 22:19:59 UTC  

b-but my amps

2018-01-30 22:20:03 UTC  

you want
1) thick traces
2) clearance

2018-01-30 22:20:18 UTC  

it just looks like thick traces

2018-01-30 22:20:28 UTC  

clearance is not so

2018-01-30 22:20:34 UTC  

THICC traces for THICC amps

2018-01-30 22:21:04 UTC  

Prolly was just cheap to make with through-hole parts

2018-01-30 22:23:59 UTC  

with this much wasted space you would think the clearences would be at least 1mm

2018-01-30 22:24:05 UTC  

they can afford to space things out

2018-01-30 22:24:32 UTC

2018-01-30 22:25:18 UTC  

its about 0.6mm

2018-01-30 22:26:27 UTC  

stop talking about your dick

2018-01-30 22:28:16 UTC  

some1 ban this underage
