Car PC MP3 Player

This is a computer I built for my car, its an MP3 music system but can also do other tasks. Based around a super-small sub-micro ATX motherboard from a computer known as the BookPC BKi810, I have put the motherboard, hard drive, and a 12 volt power supply in a small case that fits under the seat of my car. Total size is approximately 11 x 8 x 2 inches. The motherboard has a lot built in. The connectors, from left to right, are mouse, keyboard, 100 MB ethernet, 2x USB, printer, S-Video, composite video, VGA video, joystick/MIDI, audio out, line in, mic in, and then two connectors I added: power in and remote control. The main case has latches to keep it shut, and make it easy to show off the internals. Unfortunately I have not found a source for these plastic enclosures, this was one salvaged from a 15 year-old professional modem! The CPU fan is also the system fan.

This project involves the integration of a sub-micro ATX motherboard into a compact enclosure designed for automotive use. The BookPC BKi810 motherboard serves as the core of the system, providing essential computing capabilities and connectivity features suitable for an MP3 music system and additional tasks. The compact dimensions of the case, measuring approximately 11 x 8 x 2 inches, facilitate its installation under a car seat, optimizing space without compromising functionality.

The motherboard is equipped with a range of connectors that enhance its versatility. From left to right, the connectors include ports for a mouse and keyboard, a 100 MB Ethernet port for network connectivity, two USB ports for peripheral connections, a printer port, and various video outputs (S-Video, composite video, and VGA video). Additionally, it features joystick/MIDI ports for gaming or music applications, audio out for sound output, line in for audio input, and a mic in for voice input. Two custom connectors have been added: one for power input and another for remote control functionality, allowing for convenient operation of the system from a distance.

The enclosure has been designed with latches to secure the components while also allowing for easy access to the internals, which may be beneficial for demonstrations or future upgrades. The choice of a salvaged plastic enclosure from an older modem highlights a resourceful approach to sourcing materials, although it presents challenges in finding suitable replacements for future projects. The cooling system is managed by a CPU fan that also functions as the system fan, ensuring adequate airflow to prevent overheating during operation.

Overall, this automotive computer project represents a blend of creativity, technical skill, and practical application, showcasing the potential for integrating computing technology into vehicle systems for enhanced entertainment and functionality.This is a computer I built for my car, its an MP3 music system but can also do other tasks.
