If you’ve never been to a chiptune show – yes, they exist – you’ve noticed the awesome visuals behind the performers that are usually displayed with a glitching NES. If it’s a really good show, that 8-bit visualization will be in sync with the music and may actually serve as a lo-fi spectrum analyzer. [Andy] [...]

[Camilo] built a spectrum analyzer to use with his audio system (translate). The hardware is quite simple, using an op-amp, microcontroller and LCD display. He chose an LMV324M low-voltage op-amp which connects to the incoming audio signal and feeds its output to the microcontroller’s ADC. In this case, he chose a Freescale microcontroller from the HCS08 [...]

This year, students working for Texas Instruments as part of their Co-op program were challenged to construct a project around the company’s MSP430 microcontroller. A team of three students, [Max Thrun, Mark Labbato, Ian Cathey] decided to build something that would fit perfectly in any college student’s dorm room – an RGB LED coffee table. [...]

[Fred] dropped a note in our tip line to let us know about arduino forum user [bilbo]‘s latest project: A 3-in-one spectrum analyzer, oscilloscope, volt-meter combo. The build consists of an Arduino, radio board and Nokia 5110 LCD breakout board.  The (thin) video after the jump shows the rig in action. Though soldered to a [...]

[Debraj] wrote to us describing a project he recently completed – a  simple, compact spectrum analyzer using a 16-bit dsPIC microcontroller. The analyzer is fed an analog signal, which is passed through a large resistor followed by an opamp. A DC offset is then applied to the signal, after which it is passed through a [...]

[Simon Inns] just rolled out his latest project, a PIC based spectrum analyzer. He’s using a Fast Fourier Transform routine crafted in C to run as efficiently as possible on the 8-bit chip. The video after the break shows that the results are quite pleasing, with just a bit of noticeable lag between the sound [...]

A small, cheap spectrum analyzer with an LCD can be a fun thing to play with. But to be truly usefully you need access to raw data, and lots of it. [Travis Goodspeed] set out to make that possible by pulling data with a GoodFET and a Python script. He started with [Michael Ossmann's] IM-ME [...]

[Michael Vincent] turned his TI-84 Plus into a spectrum analyzer. By running some assembly code on the device the link port can be used as an I2C bus (something we’ll have to keep in mind). After being inspired by the cell phone spectrum analyzer he set out to build a module compatible with the calculator [...]

[Taichi Inoue] put together this beautiful visualization system called Yukikaze, japanese for “snow wind”. Basically a spectrum analyzer, Yukikaze is delightful to watch. We would love to see what kind of response he gets, as most of the footage shows very slowly changing smooth jazz. While we don’t think he gets crisp EQ visualizations out [...]

[Paul Klemstine] is working on some PC-side software hacks for the IM-ME. We’ve seen a lot of hardware hacks for this device, such as controlling the display, firmware flashing, and using it as a spectrum analyzer, but if you don’t want to alter the device right away you can try [Paul's] collection of hacks. Working [...]

[Michael Ossmann] rolled out some firmware that makes his IM-ME into a Spectrum Analyzer. He met up with [Travis Goodspeed], who authored the IM-ME flashing guide, at SchmooCon and spent some time hacking wireless doo-dads in the hotel bar. Once he arrived home the new firmware was just a few coding sessions away from completion. [...]
