Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Prepare the Case
You can use all the types of cases because the speakers, powerbank and module are very small,i have choose to do my own wood case.
Drill the holes for the speakers for the front and cut the pieces for the case, i had to trim the front/up sides of the wood case to be abble to fit the speakers.
Step 2: Front Part
Place the speakers in the correct position and secure them with small wood pieces glued with wood glue, when its dry remove the speakers and glue them using contact glue and hot glue
Step 3: The Switch
Mark the position of the switch and cut it carefully, i connected directly the switch to the power bank positive usb cable (red one), the switch controls the power output of the powerbank.
I have also apply some clear lacquer to protect and give a better look to the wood.
Step 4: The Electronics
its very simple , follow the schematic, to recharge the power bank connect an mini usb extension on the back of the case, isolate all the exposed wiring and solders with shrink tube and hot glue, do an hole on the back cover to expose the mini usb cable to recharge the powerbank.
Step 5: It Works !!
It as a nice sound, the battery should last plenty of hours, once again learning a little bit more in every project.
Tank you for watching.
