Mounted ZX Spectrum tape covers.
Mounted front panel from a dead, vintage audio amp. Holes are backlit with LEDs and the dials cycle up and down. You can control the speed and lighting by touching the wood on top of the frame - a capacitance based qprox sensor detects the proximity of your hand to act as a switch.
The switch is multimodal; a quick touch cycles the lighting modes to on/dim/off, holding your hand there for 3 seconds enables the speed setting mode - the dial increments one level on the panel meter per 2 seconds held, ie, hold your hand there for 10 seconds and the dials take about 30 mins to cycle, hold it there for 1 second and the dial will cycle at once every 2 seconds.
All control is done with a PIC microcontroller (before I swapped to AVR). This was my first electronics project.

Microchip Technology Inc., a leading provider of microcontroller, analog and Flash-IP solutions, today announced the MCP1754/MCP1754S low dropout regulators (LDOs). The devices feature a high PSRR of 70 dB at 1 kHz (typical), and a maximum output current of 150 mA at +125 degrees Celsius junction temperature. Both LDOs offer a high input voltage of 16V and an output voltage range of 1.8V to 5.5V, with standard output voltages of 2V, 2.5V, 2.8V, 3V, 3.3V, 4V and 5V, and output voltage tolerances of +/-2.0 percent over the entire temperature range. The MCP1754 provides enhanced features, such as a shutdown input signal and a power-good output signal, while the MCP1754S is the baseline version of the device. These LDOs are ideal for electronic circuits, such as in GFCI and AFCI circuit-breaker designs, and in the automotive, medical and consumer electronics markets, such as in automotive power adaptors, cell phones and medical devices.
Microchip’s 32-bit PIC32 microcontrollers provide a high-performance platform for developing quality digital-audio playback and accessories.

Microchip announced the expansion of its Low Power PIC® microcontroller (MCU) portfolio. Features of the new PIC24F “GB6” family include up to 1 MB of Flash memory with Error Correction Code (ECC) and 32 KB of RAM, making it the first 16-bit MCU in Microchip’s portfolio to offer such a large memory size. Also featuring dual-partition Flash with Live Update capability, these devices can hold two independent software applications, permitting the simultaneous programming of one partition while executing application code from the other. This powerful combination of features makes the PIC24F “GB6” family ideal for industrial, computer, medical/fitness and portable applications that require a long battery life, and data transfer and storage without the need of external memory, such as electricity metering, HVAC control, fingerprint scanners and gaming. For more information of the GB6 family, visit: www.microchip.com/PIC24FGB6-112315a
Microchip expanded its eXtreme Low Power (XLP) PIC® microcontroller (MCU) portfolio. Features of the new PIC24F “GB4” family include an integrated hardware crypto engine with both OTP and Key RAM options for secure key storage, up to 256 KB of Flash memory and a direct drive for segmented LCD displays, in 64-, 100- or 121-pin packages. Dual-partition Flash with Live Update capability allows the devices to hold two independent software applications, and permits the simultaneous programming of one partition while executing application code from the other. These advanced features make the PIC24F “GB4” family ideal for designers of industrial, computer, medical/fitness and portable applications that require secure data transfer and storage, and a long battery life.

All these 8-bit retro computers were loading software from MMC cards using an interface and firmware by Arduino Nut.
Input was the audio out from the netbook. The AC signal is quite reduced by the time it gets to the microcontroller. It is added to a DC bias set by RV2. Mine is set to just under 1.5V.
A technique for setting RV2 is to increase the bias voltage while playing music into Pin 5 of the radio connector. Don't start too low or you'll short out your music player. When the "CD" LED comes on stop increasing and stop the music. The CD light should go out after a couple of seconds. Then start the music again and see that it comes on.
You can measure the bias on Pin 10 of the PIC or Pin 2 of the radio connector. The picture shows measuring using a Picoscope PC oscilloscope on Pin 10 of the PIC.
DK7IN has some interesting notes on this at www.dk7in.de/TinyTrak_e.html
I reckon a simple circuit can decode the signal, something I'm working on in software simulation at the moment and fingers crossed could try in hardware.
