You can build the tiny XFM2 synth for under $100
Miniature electronics kits like the Raspberry Pi have ushered in a new generation of DIY tinkerers. And while most of these builds emulate classic gaming systems, there are plenty of other possibilities. Futur3soundz, for example, designed a synthesizer around an FPGA chip and an Adafruit digital-to-analog converter. The company says that the components can all be purchased for under $100. And while the synth has few on-board controls, it has an extensive MIDI integration, so musicians can control parameters from their keyboards, making it a viable piece of bedroom studio gear.
