Today we are making this, exploding clock with motion lighting!
Hello, and welcome to DIY Perspective.
In this video, I am going to show you, how to make this unique looking wall clock, which
has an integrated motion lighting system.
What's really cool about this system, that it's powered just by two Lithium-Ion batteries,
and it should run for about 100 hours.
It might seem not so much, but when you consider that if you trigger clock's lighting system
for 15 minutes every day, batteries should last for around one year, which is very impressive.
Another thing, you can make this clock from a single wood square, of 21 centimeter side,
which makes this design quite material efficient too.
So, let's start making this clock by printing my made template, marking boundaries, in which
we need to add paper glue, and glue the template on the wood board of 18 millimeter thickness.
We need to drill 11 millimeter depth hole for the router bit, and start routing.
If you don't have a router, you can drill as many holes as you can, in the area which
needs to be removed, and by using a chisel, carve required space for the electronic parts.
However this takes long time and you cannot control depth that precisely.
As I started routing, I saw that because of the tearing paper it's hard to see the edges,
so I removed it with a utility knife and continued routing until I could fit all the electronic
pieces perfectly.
Now, we can move to cutting small square pieces from the template.
I made 1 millimeter gaps between pieces, to make it easier to cut them out, as jigsaw
blades usually are around 1 millimeter width.
When we have done all the main cutting, now we need to cut left parts like these, which
was impossible to cut with a jigsaw, but is very easy to cut with a fretsaw.
We need to sand all parts with 120 and 220 grit sandpapers, to get all pieces looking
from this to this!
Now, we need to drill a hole for the clock mechanism and for the infrared motion sensor.
For the sensor, first drill hole of the size as the sensor and then drill thinner hole.
This will make sensor to trigger at more direct and narrower angle.
At this point, we have finished all the cutting and drilling, so now we need start gluing
square pieces to the main part of the clock.
We need to add something beneath the main part of the clock, this way it would be easier
to glue small square pieces.
Use the template to know where to glue different wood pieces and mark them off one by one,
when you glued it.
I used high quality wood glue and I fasten drying process with a hair dryer.
When all pieces are finally glued, now we can see how truly unique this clock looks
even without any finish or lighting.
But you know me, I need to add some sort of electronics to it, and take this build to
a next level.
So now, we need to cut 50 centimeters of the unprotected RGBW LED strip and place it around
clock's back.
Then, we need to mark sports where we glue small blocks, which will be holding these
white looking LEDs.
They produce RGB colors and yellow ones produces white color, which we won't be using.
We need to glue the template on the 6 millimeter plywood, cut all small blocks and sand them
down.
Then glue each block to the marked spot on the clock's back.
And when glued parts dry up, we can start applying finish to the wood.
I applied one coat of white color paint, but there are so many other ways to finish wood
for your own taste, so choose finish for your own liking.
I just suggest finishing back of the clock with a bright color for the better lighting
reflection from the LED strip.
In the next step, we need to start connecting our electronic components for the clock's
backlight.
For this, we need to have NPN type transistor, RGBW LED strip, two protected Lithium-Ion
batteries, holder for them and infrared motion sensor.
What's cool about this sensor, is not only that you can adjust its detecting sensitivity
and duration, but you also can adjust triggering type by changing this pin's location.
Let me explain.
Let's say sensor trigger time is set to 30 seconds.
So when this pin is set inwards the circuit board, if you trigger sensor on 15th second,
timer resets, and counts another 30 seconds.
While if you set this pin to the outer position of the circuit board, it triggers just one
time and runs 30 seconds no matter what.
So now let's move to short explanation of whole circuit.
Basically, when the motion sensors detects movement, it sends small voltage signal to
the transistor, which reacts to that voltage, and connects battery straight to the LED strip.
Simple enough, right?
We need to start with connecting this DIY battery box in series, by soldering one end
connectors together with a small wire and then bending them, that the box would fit
perfectly.
It's good idea to place some electrical tape inside the box and mark polarity of the
batteries.
In other end of the box, we need to solder two 15 centimeter wires, and bend connectors.
Then solder two short wires to the LED strip connectors.
Mine for some reason, glows red when I connect negative wire to letter "g", which makes
no sense.
So check if your strip gives color that you want before soldering.
Next, we need to cut those long legs of the transistor and add some solder to it.
Then solder the transistor's leg which is called "base" to the middle connector
of the sensor.
To sum up, transistor has 3 legs – one is called "base", other is "collector"
and another is "emitter".
Order of those legs can be different, so it's important to know which is which.
Moving on, we need to solder extension wires for the positive and negative connectors on
the sensor, and then solder negative wire from the LED strip to the "collector"
on the transistor.
Now, we need to connect and solder 3 positive wires – one from the sensor, second from
the LED strip, and third from the batteries.
Then, connect negative wires from the sensor and from the batteries and solder them to
the "emitter" on the transistor.
Add some electrical tape around open wires.
Finally, we need cut away non-sticky tape behind the RGBW LEDs, put the sensor and the
battery box in place, and glue the LED strip to the small blocks.
I additionally used super glue to quickly and firmly glue LED strip to those blocks.
Then, we need to add hot glue on the wires, and if other components doesn't hold well,
hot glue them too.
Put in Lithium-Ion batteries, add and tighten clock mechanism, add clock arrows and insert
battery.
Also, add some more electrical tape on the sensor, to prevent from accidental short circuit,
when you hang the clock on some sort of metal hook or a nail.
And finally, we are done!
I really like the result of the clock.
Even without lighting, it looks very good and unique.
But that motion lighting system, I think, it just takes this clock design to a next
level.
I love, that even in the daylight you can easily see the red glow, when you move your
arm in front of the clock.
Few suggestions, is that you place the clock above your head level to avoid sensor trigger,
when you walk next to it.
And don't place the clock in position, that the sun beams could directly travel to motion
sensor, to avoid false triggers.

That's all from me in this video and will see on the next one!
And no, the clock arrows doesn't trigger motion sensor.
