The Slurptop: A home-built luggable that runs on power tool batteries

The "Slurptop" is a home-built laptop-like computer that runs on power tool batteries. This project was inspired by a desire to have a full-fledged x86 portable computer, similar to a laptop, after experiencing other Raspberry Pi-based builds. The initial design process involved considering Intel N50 and N100 mITX motherboards and PicoPSU power delivery, but the cost and power consumption concerns led the author to explore mini PCs with laptop processors and integrated graphics.

Power delivery for the Slurptop was achieved using a 24v power tool battery, paired with a properly specified boost/buck converter to ensure compatibility with the laptop processor's 19v/5a power supply. The design process also included crafting a trackball mouse, using a Corsair M65 (non-ultra, non-pro) model with an ADNS-9800 sensor and KMK firmware.

The battery is an off-the-shelf item that operates between 25v and 19v, with a low voltage cutoff to prevent damage to the cells. The Slurptop project embodies a blend of aesthetic appeal, improvised hardware selection, and functionality, aiming to satisfy the needs of coding and light design work.
