as you can tell by the uh lack of a pint glass over there i'm on call for work this week and
so i don't have a lot of time to throw together a video so i thought i would just uh take a look at
these little 3d printable spotlights that i found on thingiverse and probably on a few other
online 3d printing sources they're kind of neat too so the file that i found came basically
with three parts the barrel the front barrel here this one um the back housing and the yoke
that holds it up this base is just something that i randomly printed just to stand it on
you'd be able to screw it to just about anything and the guy who originally designed this
said that he designed it to mount onto t-nuts on the frame of his 3d printer to shine down
onto the bed which is pretty cool i thought there are actually two different versions of the front
barrel available there's that long throw spotlight one and then there's this short one um that you
can put on there which also does a uh does more of a flood light a little bit wider beam kind of
thing and even with the bright studio lighting that i've got going on here let me shade it a
little bit you can sort of see it in the file that you download there is also a gel frame that you
can drop in the front here but i haven't bothered to use it because you know i don't need to i also
found a remix of the file which is basically the same front barrel except for it comes with
barn doors and i just put some bits of wires in there to use as a handle or as a hinge rather
and then this can kind of cut down and shape the beam a little bit let's again shine it on the mug
and you can sort of uh shape the beam how you want it
which is pretty cool and that's that is a standard thing in theatrical lights has been forever
so the light that is designed to fit inside that is these little star style i think big
clive calls them luxian star style uh one watt leds suppose you could find a
three watt in that same size it would fit in there too but that's what that is in there
and that's what i've got in here just on a couple of short little uh wires there is a little bit
of room in the back there for electronics but not too much i've been thinking about putting
some control electronics back there so i can do some other fancy things but i'm not sure
of course those star-shaped leds are not just available in white they're also available in rgb
and why just print one light when you can print a bunch of them
so here we have two different ones doing rgb under control of this arduino nano
using two slightly different methods well same but different this one on this side is just a
standard neopixel aka ws2812 led it's just on a little circuit board like that there you can
see the pins on the back of it it's got five volts in ground and then data in and data out
all the way across you just snap these individual circuit boards off and solder them down to
whatever you want and in this case i've just put it onto a little piece of perf board and then ran
it uh four wires out in some heat shrink sleeving onto some pin headers and it gets its control the
same way as any uh ws 2012 led does and then the voltage comes in separately so that's that one
this one is one of these exactly one of these i'm not sure if you can see i've commoned up the red
green and blue positives down there and then ran the negatives out on wires out the back here and
i didn't have any red so i used orange but green blue and that one is the common and those land
on aws 2811 back there which is the control chip that's in the neopixels of the ws2812s
just separately as a standalone little chip i've got mine mounted on a breadboard adapter
but it is a surface mount chip and then it's taking exactly the same data from the arduino
uh into it and then its data out is going over to this one and i could if i wanted to add extra
neopixels into the string i'm not going to right now but i could if i wanted to i did
when i was experimenting earlier so i could use either of those methods to daisy chain
a whole bunch of these things together and create myself an entire light show i think
that might be pretty cool to do you know from an old rock and roll kind of uh kind of a standpoint
i think i'd probably use these floodlights mostly just because it throws more light around but uh
yeah i think that'll be pretty cool i'll put the links down in the description but here
is the light that i downloaded to print out as you can see it's a 1 12 scale stage spotlight
and this is what the guy originally designed it for is lighting up inside his printer cabinet
which is kind of cool the file comes with the back piece the short front piece the long front piece
this gel frame on the front which i chose not to print the yoke and this little spike
for i guess mounting it into i don't know what a flower pot maybe to light up a plant something
and i did find there is actually somebody's made a base for specifically for it but that's not the
one that i used but i'll put a link to this one as well just in case you feel like doing this and
here is the remix basically they just change the front around a little bit and added the barn doors
that you just put a piece of wire through there as a hinge i used uh 18 gauge solid wire and so
you print off four of those and one of the front barrel and you too can have your own rock and roll
light show i'm going to have to find the file for this piece this truss work and print off some of
that that looks pretty cool i think i might want to do that i don't know why i want to do that
i just want to or if you prefer you can also get this remix of the light from prusa's printables
website it comes just with i think that's the i think that's the longer barrel but he's
added in his remix this little snoot on the front of it to focus the beam a little bit more
and the ones that i put together i used an m3 screws to hold it together
this guy's added this little friction pin for the hinge point so either is an option
and then the leds as i said are available in all sorts of places i'll put a link down below
to this well to one listing i'm not sure if it'll be this one another one it might be a search term
but it'll get you close in order to fit properly into the housing get the one with the pcb
um one watt i suppose i suppose you could get three watt but one watt's probably bright enough
i don't think you'd want to heat it up too much with the three watt and then there's a variety
of colors you can get you know any standard led color or you can get the rgb version
i guess just for completeness there is the version of the ws2812 that i used
on these little pcbs you can get the circuit board in white or black i just happen to have
white ones and so 50 of them for 1538 canadian with free shipping that's not too bad at all
so just a quick fun little video today um nothing too high tech i just thought these
were pretty cool and interesting to play with so i figured i'd share it thanks for
watching uh questions or comments down below as usual i will talk to you later
