hello everybody I'm gonna present you today how to make a bench power supply
out of this DVD player as you can see it here alright so let's get started for
this project we're gonna need an old DVD player preferably functional some kind
of container or plastic thingy to put the power supply in or lab bench power
supply for this project I'm going to use this old nail polisher bottle it's
alright and funny shape and this all DVD we're going to open it up this stuff
you're going to use the power supply of it and as well these connectors here
okay alright friends we are back now we have the main board which is this one
over here this is the power supply of that DVD that I should record here it's
got here a switch which is convenient this is the input side that goes to the
mains and here normally it's got some output as we can see here we got a
ground symbol here so I'm using this one is going to have two outputs probably 5
volts and 12 15 or so yeah let's put it in the mains and test it out to see what
voltage is going to give us our future power supply ha mate yeah alright so we
have the board we have this connector that we're going to plug into the main
so be very careful when you're going to use them
the mains voltage we're gonna connect it we're going to flip it over and we're
going to start from here and measure this outputs always connect your finger
to the cable before you're going to plug it to the mains okay we have our power
supply and we're going to connect it to the mains
all right so no sparks or nothing all right
so now we're very careful what you're gonna hear this board just flip it over
we got a switch here and now with our voltmeter then go into the 20 range 20
volts range power it up oh okay so no sparks it's okay it's working yeah let's
see so I said this one over - all right so we got a 4.5 volts and 12 so we have
figured out the pins is this one here which is 16 come on 16 points free and
this one
these 4.6
all right so we're gonna have to output 15 16 volts and 4.5 5 volts alright so
let's proceed alright so we have our board we have
this plastic container we're going to measure bottle like so we're going to
cut it open we're gonna insert it inside and then we're going to solder the
connection to the this RCA connection alright stay tuned we have all the parts
necessary we have the connector I have the power supply over the DVD we have
the case and we're gonna use this 1 DVD to transfer the templates on this side
basically we're gonna need a switch which we're gonna put it somewhere here
I'm gonna mark it and transfer it to our thing
so I have the the switch and we're gonna put a little streak connectors let's see
I'm gonna put like so to be in line with the switch this is just for looking nice
my friends we have managed to have all the parts the container the power supply
the connectors and switch on and off we're going to introduce all this stuff
in this box here let's see if we're going to manage to hold on to the wires
I'm going to introduce this one in the Box time on page one so let's bring in a
plaque right place we're gonna put these cables through this hole in the back
they're going to be the main or what you see right careful as well look how nice
it's sliding in almost perfect something is happening and the wire is kind of big
a free motion stuff and I friends one more try
I have to make some minor adjustments to the hole in the back here nice joy
slide it all the way that's it let's try it one more time
yeah that's more like E
alright folks after a long process we have managed to assemble the power
supply we have here the switch we have here the input from the mains
and the board in the inside here now we can adjust put in the switch then tilt
it into position let's see which one up on now like this
it's better like so slide it in sit tight in perfectly adjust it
yeah that's it and now I have to move for you to be the board to be able to
slide in the connectors I said this one is 12 volts so I have to tilt this one
we have to put something in between these wires and the board be back so
that's it folks we managed to assemble the power supply we're just going to
need to put a screw here to hold on the connectors there this is it friends our
finished product our lab bench power supply
homemade we got two outputs for 15 kinda and 5 volts on switch and this is the
thing what do you think huh looks kind of shitty but he's gonna do the job so
it was free so you cannot complain about it
to connect to those thingies we're gonna use this one as well as from from the
DVD player as well so let's connect it and then a multimeter test alright
friends we have connected our power supply to the mains power switch right
we're gonna connect the probe to the 15 volts output we're gonna turn it on and
we will see if we're gonna get 15 volts here we go fourteen point six yeah so
it's working let's connect it now to the second output this okay alright yeah
four point two that was all for us today friends thanks all for watching see you
next time in the meanwhile thumbs up subscribe and the full project is gonna
be on the description below on to instructables.com thanks for watching
see you next time bye bye a power bank babe
