3. Coin battery
4. Acrylic casings
5. LEDs
6. Plastic bolts
7. Plastic standoffs


To get two smaller casings from the kit,
you’ll need to break one large acrylic piece.

But please, be super careful when
doing this to make sure you don’t
damage the parts you need.

After breaking it, you’ll end up with two separate pieces
of acrylic casings. If you find there’s any acrylic in the
holes of the casings, just gently push it out.

Remove the protective foil from both sides of the casings now.

Your casings should be all nice and transparent now.

Now, let’s dive into the
exciting assembly part!

Start by grabbing the casing that matches the one in the
photo below and gently place it onto the PCB.

Now, for the next step, put the second casing on the backside.

To make sure everything stays in place, we’ll need to
secure these casings with bolts and standoffs.

Here’s how you do it: put the
bolts in from the front and add
the standoffs onto the back.

Fasten the standoffs
with your fingers – no
need for fancy tools!

Now, insert the battery, making sure the + sign is facing up.

When it comes to
Marv’s LEDs, it’s
super easy. You’ll
find the polarity
indicated by plus
and minus marks.

So, when you turn on Marv and start adding LEDs, just be sure to pay attention
to their polarity as you connect them. Look for the cut-off (-) and rounded
(+) parts marked on the LED – they’ll tell you all you need to know.
And hey, if you flip Marv around, you’ll spot those + and - signs next to each
connector. These symbols are your guide to getting the polarity right.

Now, here’s where the magic happens: When you turn Marv on,
the LEDs in the circle will light up one after the other.

Ever wonder how Marv’s
decade counter works?
Well, here’s how:
If you press the
pushbutton on the
bottom right side, the
LEDs will stop in the
start position (left eye).

But if you press the
pushbutton on the
upper right side, the
LEDs will pause right
where they are.

Need to change the speed of the counter? No problem! Marv’s got a
handy potentiometer on its back. Grab a screwdriver, and with a simple
twist of the potentiometer, you can adjust the speed to your liking.

We hope you had a blast putting Marv together and maybe
even picked up some cool insights into how it works.
