Hey I'm bob and I like to make stuff
Today I'm going to show you how I made this 4 player quiz game
From another project I had several strips of excess plywood
so I ripped them down into 4.5" strips
then I held those strips up against the blade and set my stop block.
this way I could cut them down into perfect squares.
once I had a bunch of those cut I took three of them and glued them together.
not along the insides but just around the outside
then i added some clamps to hold it together while the glue set up.
after the glue had dried i took it to the band saw and cut out the middle of the box
now this is kind of like you would do if you were making a band saw box
i went in from one side and cut out a section in the middle
i added some glue to the section i had cut out and clamped it back up to dry
i made four of those in total, one for each player
and each one of these had a top panel where i marked centre point
before glueing and clamping it on.
after they all dried i used a forstner bit, a 1 and 1/8" bit
to drill a hole at the centre point of each one of the boxes.
this is just big enough for an arcade button to drop in
for each one of these, I took another panel and countersunk some holes into each corner.
i screwed these onto the bottom of the box, to make a solid box
after each box had a bottom i took all of them to the disc sander.
this took a little while but i squared off all 6 faces on all four boxes.
then i took each one to the belt sander
and this helped me make a roundover on all of the corners.
its not entirely necessary but it was a nice feature,
since these were gonna be held by kids
i rounded over as much as i could
but even in the corners they were still a little sharp
so i used an orbital sander to knock those down
and kind of finish everything up.
for the control box i cut up some more plywood to the same width
but then cut it twice as long.
to make a rectangle instead of a square.
follow the exact same process for all of the other stuff
to end up with just a larger version of the same box.
once they were all sanded, i sprayed a few coats of spray laquer
on all of them
each one of these arcade buttons has 5 terminals on it,
but we only really care about four of them.
two are for the LED and two are for the button itself
since each one of these has four wires coming off of it
im gonna use a phone cable, because its four conductor
all in one piece of insulation.
i cut the end off of a cheap phone cable
and then stripped off some of the outside insulation
being sure not to strip off the insulaton from the inner wires.
i cut four sections of this wire
and then i had to strip each one of the inner wires
on both ends in each cable.
this is the wiring setup for a single button,
just so its easier to see whats going on.
you start with an Arduino Uno
that has 5 volts in ground going to a perf board
then i have the arcade button with the four wires connected
and they go also to the perf board.
there are 2 resistors in play here, one for the LED and one for the button
both of these have a line that got to a pin
on the Arduino
this is what it looks like on the bottom
i added all the other buttons in the exact same way
and its messy to look at but they
are all the same, just spaced out across the board
when i unscrewed the bottom of the boxes
i made sure to mark one side
so i knew which direction to put them back on
and then i dropped in the buttons and screwed them on
with the nut that comes with them.
th wire needed to go through the box
so i marked a small area,
and cut out just enough area for the wire to fit through.
i twisted the LED
and the button into the button housing
and then super glued in the wire into the slot
i tried hot glue as well but superglue worked much better
i gave it a test and then did the same for all of the other buttons.
the only difference for the control box
was that there were 4 wires coming in,
and i had to cut slots for each one of them.
i added in the single reset button
to this box but it doesnt use the LED
i added the perf board and the Arduino to the top
of the inside of the box with a screw each
then i chiseled out a small are for a power cord to fit through,
and glued it in place.
i also glued in the 4 cords coming out to each one
of the controllers
to prevent any of the wires from falling,
out of the Arduino
since it was upside down, i added some hot glue
to all the wires to kind of lock them together.
this also acts as an insulator just in case
i used it just to hold wires in place inside the box,
and then screwed the bottom on.
then, it was done
i made sure to test all the buttons
to make sure everything worked before taking it
to the kids, to see if they liked it.
the first button that gets pressed lights up
and once one is lit up
none of the other ones will light up
until i hit the reset button
that way we know who is the first person to answer
*Button Clicks*
A mallard duck?
yay!
a male!
grizzly bear? Yup!
That was a grizzly bear
Yeah! *kids laughing*
a white chicken? yes!
*inaudible words*
really quickly i gotta tell you about something
thats coming up over the next couple of months
i got asked by a company called Quarterly
to curate the next maker box.
basically every 3 months
they send out a maker box
with a bunch of cool stuff,
and in this case i get to pick out what goes in the box
i cant tell you whats in the box,
but, if you know me,
you will get a pretty good idea
of the type of thing that i will put in that box
basically, you just subscribe to the box,
when it ships in may of this year
they will send it to you
and you get a bunch of cool stuff to work on.
its all stuff that you can do with your hands
things that you can actually make
and theres gonna be a note inside from me
explaining kind of whats in there.
so be sure to check out Quarterly
if you're interested, and subscribe for the maker box.
id love to know what you think about this one
you can let me know in the comments below
or my website, iliketomakestuff.com
also on the website i got articles
and videos for everything that i've ever done
as well as a bunch of plans you can buy
and t-shirts and all sorts of stuff.
be sure to check out the website!
ive also got social links down here
and lots more videos for you to check out
thats it for this one, thanks for watching,
ill see you next time.
