SP Semi Automatic Paintbrush
Any work of art are often copied using this and therefore the elements that are needed to form this is often listed below:
IR camera
InkShield
Ink cartridge
IR LED.
The software thats run on a desktop for this purpose is understood as paintbrush.py. The software plays the role of mapping the camera focus with the co-ordinate system of the canvas. Four LEDs are placed at every corner of the canvas and therefore the mapping is calibrated by hitting a key when needed.
The region of the image is captured by tracking the motion of the LEDs. the mandatory commands are send to an Arduino with the InkShield by means that of a script written for this purpose. The script tells the arduino that nozzle to fireplace and additionally the grey level that must be achieved by the firing nozzle. so as to avoid flooding, the painted areas are tracked.
Thats all its. The paintbrush is complete. this is often a lot of of a fun-based project and may be tired some spare time using the elements mentioned earlier. the desired script is out there on github. The InkShield library employed by the

Automatic Headlight Reminder
Do you drive an older car without an automatic "lights-on" warning circuit? If so, youve probably accidentally left the lights on and flattened the battery on one or more occasions. This headlights reminder circuit will prevent that. Its more complicated than other circuits but its also more versatile. As shown, the circuit uses two low-cost ICs. IC1 is a 555 timer which is wired to operate in astable mode. Its output clocks IC2, a 4017B decade counter. IC2 in turn drives a row of indicator LEDs and also resets IC1 (after about 10s) via transistor Q2.
The circuit works like this:
When the ignition is on, transistor Q1 is also on and this pulls pin 4 of IC1 low. As a result, IC1 is held reset and no clock pulses are fed to IC2. Conversely, if the ignition is turned off, Q1 will turn off and so IC1 will start oscillating and sound the piezo siren. At the same time, IC1 will clock IC2 and so LEDs 1-10 will light in sequence and stop (after about 10s) with the last LED (LED10) remaining on. Thats because, when IC2s O9 output (ie, pin 11) goes high, Q2 also turns on and this pulls pin 4 of IC1 low, thus stopping the oscillator (and the siren).

Note:
That different colored LEDs are used to make the display look eye-catching but you make all LEDs the same color if you wish. Installing optional diode D1 will alter IC1s frequency and this will alter the display rate. Finally, if the lights are turned off and then back on again, the alarm will automatically retrigger. LED1 is always on if the lights are turned on. If you dont want the LED display, just leave the LEDs out.
