How to Make a $20 PC
This is a raspberry pi zero PC! I made it because I have seen cool videos on YouTube by the wrench
Supplies
WARNING! This computer is very slow
old modem box
raspberry pi zero w
5V fan
hot glue
jumper wires
exposed wire
insulated wire
3V LED
portable charger
raspberry pi sticker (optional)
Break the Modem
In this step let’s take apart the modem (I already took out the electronics)
Insert the The Charger
Put the charger in mine fits perfectly so I don’t need to hot glue it
Insert the Raspberry Pi Zero
Insert the raspberry pi zero w this also fits perfectly
Solder the Pins
Solder the pins red to the 5V GPIO and black to ground
Attach the Fan
Bend the wire to look like a fishhook. Then put the fan up to the side and stick the wire through and bend the other side of the wire
Connect the Fan
Connect the wires of the fan to the soldered pins of the raspberry pi
Solder the LED
Hot glue the LED to the power indicator of the modem then solder the led anode to 3.3V GPIO and cathode
to ground. This way when you plug in the charger to the raspberry pi the LED should light and the fan
should turn on
Connect Everything
Then connect everything
That’s It!
that’s it. everything should be working!
