In the world of hobbyist microelectronics, surface-mount technology (SMT) has for many years been regarded as beyond the capabilities of mere amateurs, who prefer the larger, easier-to-handle through-hole technology (THT).
However, as components have got smaller and cheaper, SMT has become unavoidable, especially for devices based on modern microprocessors, which often come only in SMT format.
Now German hackers’ collective Embedded Ideas has posted a step-by-step guide to creating an SMT setup that avoids the need for a traditional (£1k+) reflow oven, instead using a £20 USB-powered hotplate.
The article is illustrated by a hack that upgrades the display of an old Game Boy console to colour using a small RP2350 ARM processor.
Another Game Boy hack, this one using an FPGA to add a VGA and HDMI interface, is also discussed.
