Arduino based GPS data logger to SD card

You can use GPS data for many interesting projects and experiments. By analyzing logged data you can track the movement of the object, analyze you hiking route, RC plane model, weather baloon and other crazy stuff. Building such logger isn’t very complex task as it involves only standard modules and practically no soldering needs to be done. Almost all standard GPS modules support so called NMEA0183 data format – a short message which contains all data including position and time stamps. Once connected, GPS module automatically sends this data via serial interface. Arduino simply needs to capture it and store data to memory like SD card. In this project, data is stored in FAT32 (or FAT16) formatted SD card. Arduino accesses SD card through SD card V4.0 shield. This is… Continue reading

This Puzzlemation is Even Thrilling Than Rubik’s Cube!

You love to play Rubik’s Cube, but you’re kind of bored with the ordinary design. You’re wishing for something more challenging here? Then, this Puzzlemation might satisfy your desire! For your information, this Puzzlemation is not just an ordinary tile display, but it is an expandable platform of light and animation. Hence, it can be used to build modular animated signs, puzzles and much more (Yeah, it sounds thrilling and exciting, isn’t it?) Basically, the system has two main components, the main PIC24FJ64GA002-based tray and the tiles that can be separated. All the tiles are based on 2″ square 8×8 LED displays. The PIC24FJ64GA004 is responsible driving the LEDs under each display. Since each tile is individually powered and animated, thus you can pick them up and re-assemble whenever you… Continue reading

The 100% DIY Digital Picture Frame

In the past, our ancestors mostly putted their photos in the old-fashioned photo frames, where it is not only huge but lack of any other useful functions as well! Time has passing by and the technology keeps changing. Beside of the ordinary photo frame, you’re now have another option to choose from: Digital photo frame. The digital photo frame is not only can display your photos in JPEG format, but it can also display the photos as a slideshow. Some other useful features of digital photo frames are: They come with adjustable time interval; The user can send photos to the printer; Some additional multimedia functions, such as movie clips recorded in a digital camera’s movie mode, MPEG video files or MP3 audio; Loading pictures over the internet from RSS… Continue reading

The Compact and Powerful AVR-based Power Usage Logger

Nowadays, the electronic and electrical fields have been developed in lighting speed, especially after the invention of Atmel AVR. For those of you that didn’t know this AVR for, it’s a modified Harvard architecture 8-bit RISC single chip microcontroller and it’s the fine product of Atmel that was been developed in 1996. Do you know that the AVR is one of the first microcontroller families, which using on-chip flash memory for program storage, as the opposed to One-Time programmable ROM, EPROM, or EEPROM used by other microcontrollers at the time? Today, you’ll going to be exposed yourself to the world of AVR, by DIY an AVR-based power usage logger. For your information, this device monitors household power usage and logs it to an SD card. A simple analog front-end amplifies… Continue reading
