Cool Gadgets for the Raspberry Pi

Here are some awesome new gadgets I found over the break

Small 4.3" Monitor
Great for prototyping
Small portable screen for the Raspberry Pi
NTSC

10000mAh battery
5V, 9V, and 12V Battery Pack
2 USB ports for charging

5200mAh
5V Portable Battery Pack
1 USB for charging external devices
1 Micro USB for charging the battery
It powered my Raspberry Pi streaming 1080p video for 4+ hours

a fun after project . .. the ugly christmas sweater

so i decided to make an ugly sweater to win a nice friendly competition . . . here is my entry

Here is the code that I used:

// ugly sweater v.2

byte oneYellow = 13;

byte oneRed = 12;

byte oneBlue = 11;

byte twoYellow = 10;

byte twoRed = 9;

byte twoBlue = 8;

byte thrYellow = 7;

byte thrRed = 6;

byte thrBlue = 5;

byte fourYellow = 4;

byte fourRed = 3;

byte fourBlu = 2;

int ledDelay; // delay between changes

unsigned long changeTime;

int potPin = A2; // select the input pins for the potentiometer

void setup(){

  pinMode(oneYellow, OUTPUT);

  pinMode(oneRed, OUTPUT);

  pinMode(oneBlue, OUTPUT);

  pinMode(twoYellow, OUTPUT);

  pinMode(twoRed, OUTPUT);

  pinMode(twoBlue, OUTPUT);

  pinMode(thrYellow, OUTPUT);

  pinMode(thrRed, OUTPUT);

  pinMode(thrBlue, OUTPUT);

  pinMode(fourYellow, OUTPUT);

  pinMode(fourRed, OUTPUT);

  pinMode(fourBlu, OUTPUT);

  changeTime = millis();

  pinMode(potPin, INPUT);

}

void loop(){

  int valPin = analogRead(potPin);

  unsigned long tmDelay = map(valPin, 0, 1023, 500, 0);

  digitalWrite(oneYellow, HIGH);

  digitalWrite(oneRed, HIGH);

  digitalWrite(oneBlue, HIGH);

  digitalWrite(twoBlue, LOW);

  digitalWrite(thrBlue, LOW);

  digitalWrite(fourBlu, LOW);

  delay(tmDelay);

  digitalWrite(twoYellow, HIGH);

  digitalWrite(twoRed, HIGH);

  digitalWrite(twoBlue, HIGH);

  digitalWrite(oneYellow, LOW);  

  digitalWrite(oneRed, LOW);
