Project Ideas

• usb to sata adapter

• RC mower
• Garage Door accessible via local network, not WiFi

• Dual mode CAT5 cable tester( 4 wire, 2 pair / 8 wire, 1 to 1)

• battery replacement module for cell phones(uses LM317 and components to provide 3.7v)

• water meter monitor( use it to check if there is a leak in the rest of the water system, such as the sprinkler system)

• gutter sprayer/ cleaner : make it out of pvc.  Make sure it is rebuildable and configurable.

Ideas for CAT5 Tester Receivers

Ideas for using 1 RJ-45 jack for 2 different test modes.

Attiny85 code examples

Heres a piece of code that blinks LEDs in a particular order, similar to the lighting of a Proton Pack.

int led1 = 0;
int led2 = 1;
int led3 = 2;
int led4 = 3;

void setup() {               

  pinMode(led1, OUTPUT);
