We live in the information age. Your phone knows where you like to eat, computer programs know what movies you like better than you do, and going to a party can mean going in this life, or a Second Life. So why is your message of love still stuck in the 16th century? These days it takes more than a sonnet to melt a girl’s heart. This video tutorial shows step-by-step how to make a Valentine’s Day card for the digital age. The NerdKits team shows how to make an LED Heart Valentine’s card powered by a microcontroller. The heart features an LCD screen for a personalized message, and 20 LEDs around the perimeter that can be programmed to show any pattern. The code provided contains a “twinkle” function that randomizes the process to provide a true star-like twinkle.

What do you do if you have a spare LCD module with backlight, a weird 16 button keyboard, and a PIC16F877A microcontroller gathering dust? A monster Martian Clock immediately springs to mind.

You are probably thinking “There are hundreds of PIC clocks on the Net – do we need yet another one?

This clock is quite different than all other PIC clocks I’ve seen in this that it has multiple timers that can work with different speeds (for example, you can have one showing your local time, another working on Mars day time, another showing the moon phase, etc.)

This project uses the Simple LED Animation Kit (SLAK post) with red/green LEDs arranged in a triangle.

The three sides of the triangle are connected in parallel. Even though there are 18 bicolor LEDs (36 individual LED elements), the PIC16f628A is controlling only 6 bicolor LEDs (12 individual elements) and these are duplicated around the triangle.

On PC desktops the RS-232 serial ports are about to disappear from most computers (especially from laptops), replaced by the USB connection. This project was begun as a response to build simple ELM327 compatible USB adapter for On Board Diagnostic (OBD2) monitoring.

Theremin Style Instrument: This battery powered electronic musical instrument is a descendant of the theremin and can be played without contact from the musician. This easily – assembled, small instrument contains two infared (IR) sensors, one controlling the note, with the other controlling the octave that is played through the speaker in the front. There are seven possible notes (c-b) and 7 possible octaves of each note. The tone is reflected by one of seven colors that illuminates the center area and highlights a small indicator located on the top panel. The brain of this piece is a boot-loaded atmega chip. The source code is available, as well as, pictures and a video. Check it out here:
