Chili and Eggs

Makes a great breakfast.


Mobi go2  breakdown:

Stealth Pen testing device that appears to work as a kids game.


Pieces and Parts:

Raspberry Pi Zero W 1.4

D1 wemos mini x2

Possible Hardware STM32F103C8T6 (since i have 3 of them)

And some code I want to modify but need to make sure I toss credit too.

// JP1 is an input

byte rows[] = {2,3,4};

const int rowCount = sizeof(rows)/sizeof(rows[0]);

 

// JP2 and JP3 are outputs

byte cols[] = {8,9,10};

const int colCount = sizeof(cols)/sizeof(cols[0]);

 

byte keys[colCount][rowCount];

 

void setup() {

    Serial.begin(115200);

 

    for(int x=0; x<rowCount; x++) {

        Serial.print(rows[x]); Serial.println(" as input");

        pinMode(rows[x], INPUT);

    }

        Serial.print(cols[x]); Serial.println(" as input-pullup");

        pinMode(cols[x], INPUT_PULLUP);

    }

         

}

 

void readMatrix() {

    // iterate the columns

        if (rowIndex < 10)

            Serial.print(F("0"));

Mobi go2 Tear Down Part 1

Some pics of the tear down: First the Subject:

Next up the back of the subject with the battery cover removed.

Back of the screen hing

Now for a bunch of tear down pics

Some Test fits 

Part 1 of many to come of a stealth pen testing device in a kids toy with a screen and keyboard + extras
