Building Modular Open Source Electronics with Lukas Henkel
Lukas Henkel, co-founder of Open Visions Technology, details the engineering behind modular open-source hardware, including a Linux-based smartwatch and a Framework laptop modification. He explains the use of custom System-in-Package (SIP) designs, HDI PCB technology, and Thintronics low-DK substrates to achieve signal integrity in ultra-compact form factors. The discussion covers the challenges of sourcing documentation from major chip vendors like Qualcomm and NXP, and the strategic decision to use off-the-shelf Framework mainboards as an intermediate step for their open-source laptop project.
