  • Step 1 Unboxing

    • It's not just a box, it's also a use guide.

  • Step 2 Undo the screws

    • The Phillips screws are hidden underneath silicone covers.

  • Step 3 Pry it open and remove the front cover

    • The cover is a pain to get open. The amount of force needed is quite high.

    • The hinges are spring loaded. They tend to fly away when tension is relieved.

  • Step 4 Remove the flip cover

    • As said in the previous step, the springs tend to fly away!

  • Step 5 Remove the light conductor

    • This can simply be pulled out once the covers are removed.

  • Step 6 Pry out the button

    • A screwdriver may not be the ideal tool for this job, a less sharp object might be better to avoid damage to the silicone.

  • Step 7 Remove the lenses

    • Use the flat side of the screwdriver to avoid damage to the lens.

  • Step 8 Remove the hinges

    • You will stab yourself with the screwdriver while doing this.

    • The white parts of the hinges will very happily fly away and get lost.

  • Step 9 Remove the battery

    • Pull out the connector, be careful and only pull the connector and not the wires to avoid damaging them in the process.

    • The battery is fixed in place with double sided tape. Make sure not to bend and damage the battery when taking it out.

    • Text on the battery:

      • Grand-Pro

      • - PL805050 3.7V 8.14Wh

      • GB-GP004 UN38.3 2200mAh

      • + 11-22-2014-11265

  • Step 10 Remove the PCB

    • There are two plastic pins holding the PCB in place. You will have to break them.

    • Undo the connection between the PCB and the solar panel with a soldering iron. Do not pull the cables out, this may result in severe damage to the cables or PCB.

    • Top tip: for one time at least, you can redo the plastic pins holding the PCB by pressing a semi-hot soldering iron on the plastic.

  • Step 11 PCBA

    • Most important silicon:

      • Texas instruments LM358 Dual opamp

      • Fairchild Semiconductors MJD210 PNP Transistor

      • NXP 74HC595 8Bit shift register

      • Intivation SNBST3 MPPT Solar charger with integrated MCU (heart of the Waka Waka)

      • Dsunsolar High efficiency PET film solar panel. Custom made for Intivation.

  • Step 12 Pry out the solar panel

    • Use a flat object like a bank card to avoid bending the solar panel.

    • This Waka Waka has been opened up previously to this teardown. Since the solar panel was originally glued in place, the solar panel was re-attached using double sided tape. When putting your Waka Waka back together, you could either choose glue or double sided tape. Both work fine.
