Since 2008, ToughDev has explored embedded systems, software development, reverse engineering, and retro computing, bridging legacy hardware with modern software.

Recent projects include the Super 8086 Box PC XT emulator, the dsMP3 embedded radio, and detailed teardowns of vintage PCs such as the Tandy 2500RSX.

I also write about voice, AI, and communication products from a technical user’s perspective. My recent first-impressions review of Talk Machine looks at its voice-first interface, email-based voice notes, transcript refinement, and natural speech output.

Beyond publishing technical research, ToughDev also provides consulting and custom development services in embedded systems, mobile applications, VoIP, microcontroller firmware, and integration with vintage or undocumented hardware platforms.
