Since 2008, ToughDev has been extensively exploring a variety of technical topics—from software development to electronics design. Key areas of focus include Android and iOS programming, VoIP technologies, embedded systems using Arduino and PIC microcontrollers, reverse engineering, and retro-computing.

Recent highlights include running macOS Sequoia on a Dell Latitude, teardown of the vintage Tandy 2500RSX—a powerful 386 system by Tandy Corporation, the Super 8086 Box—a home-built PC XT emulator with full legacy hardware support— and the dsMP3, a custom-designed multi-band radio with MP3 recording and playback.
