“…The groove width of a typical record is 50.8 µm; a laser is easily capable of producing a feature in this range [2][3][4][5][6][7][8] as the minimum spot size of a Gaussian laser at its focal position is typically twice its wavelength (Khan-Malek, 2006) [4]. Therefore, using a shorter wavelength will produce a narrower groove.…”

“…Varying laser power has a direct effect on the rate of material removal. Laser ablation rates have some form of linear response as the energy, or fluence, of the laser is increased [8,[19][20][21][22][23][24]. However, the linear response may be limited.…”

“…The use of a laser opens up the possibility of utilizing materials with more favorable characteristics. Using lasers for microprocessing is an extensive research area and has covered the production of microstructures in polymers to the scale necessary for records [2][3][4][5][6][7][8]. The resurgence of vinyl record production means that laser technology is becoming an alternative to the traditional production methods.…”

The recent resurgence of vinyl music records sales led by a consumer demand is increasing faster than production capability. This has resulted in supply delays across the sector. Thus far, manufacturing investments have been focused on traditional proven methods rather than alternative technologies. This paper demonstrates for the first time the production of a stereo recording via analog methodology using a single pulsed laser beam. Using mid-side theory, to combine a sum (mono) signal with a difference signal, a 532nm Nd:Yag laser beam was used to process high-impact polystyrene discs (HIPS). Stereo recordings were manufactured by varying the laser power to produce a difference signal and deflecting the beam with a mirror mounted galvanometer to produce the sum signal. Upon playback on a conventional turntable, the recordings were analyzed with an oscilloscope and stereo separation was observed. To our knowledge this is the first time a stereo signal has been successfully recorded using a single laser beam. Previous literature has used a single laser beam to achieve mono signals and required significant digital pre-processing of the audio source. This new methodology requires lower investment costs than traditional pressing plants and would make volume-tailored production more affordable.

In recent years biomedical scientific community has been working towards the development of high-throughput devices that allow a reliable, rapid and parallel detection of several strains of virus or microparticles simultaneously. One of the complexities of this problem lies on the rapid prototyping of new devices and wireless rapid detection of small particles and virus alike. By reducing the complexity of microfluidics microfabrication and using economic materials along with makerspace tools (Kundu et al. 2018 ) it is possible to provide an affordable solution to both the problems of high-throughput devices and detection technologies. We present the development of a wireless, standalone device and disposable microfluidics chips that rapidly generate parallel readouts for selected, possible virus variants from a nasal or saliva sample, based on motorized and non-motorized microbeads detection, and imaging processing of the motion tracks of these beads in micrometers. Microbeads and SARS-CoV-2 COVID-19 Delta variant were tested as proof-of-concept for testing the microfluidic cartridges and wireless imaging module. The Microbead Assay (MA) system kit consists of a Wi-Fi readout module, a microfluidic chip, and a sample collection/processing sub-system. Here, we focus on the fabrication and characterization of the microfluidic chip to multiplex various micrometer-sized beads for economic, disposable, and simultaneous detection of up to six different viruses, microparticles or variants in a single test, and data collection using a commercially available, Wi-Fi-capable, and camera integrated device (Fig. 1 ).
