- Nick CornfordDespite the title, this DI does not describe a gadget to tell you when to don your shades, but instead features a useful add-on to (analog) audio kit. Built into a mixer, for example, it will show when the output of any stage is approaching ...Aug 6, 2024
- Stephen WoodwardWhen the Sun is shining and illumination is needed inside a dimly lit interior space, a popular, proven, and highly efficient solution is to utilize the energy of available sunlight in the simplest and most sustainable fashion conceivable: Opening ...Jul 2, 2024
- Glen ChenierBattery-operated instrument benefited from auto-power shutdown A handheld, battery-operated “fiber finder” measures the light escaping from an optical fiber when clamped in a V-shaped block under slight pressure. A pair of photodiodes ...Jul 2, 2024
- Stephen WoodwardAll thermal anemometers work by inferring air speed from measurements of thermal impedance (Z) between a heated sensor and the surrounding air: (1) where P is the power dissipated by the sensor and T is the temperature difference between the sensor ...Jun 27, 2024
- Nick CornfordIn Part 1 ( Ref. 1 ) of this article, we briefly looked at the Wien bridge oscillator before homing in on the bi-quad filter as our best candidate for an oscillator capable of giving 0.0001%/ 120 dB distortion, and showed its full circuit. Treating ...Jun 27, 2024
- Nick CornfordOver the years, the Design Ideas (DI) column has featured many interesting oscillators, but none that I can recall was specifically designed to produce a really clean sine wave. Putting that omission together with the need to rebuild my old ...Jun 26, 2024
- Vijay DeshpandeTesting the system Testing was done at various sunlight intensities. For any given sunlight intensity, V PV , I PV , V M , I M , etc., are measured. Figure 5 shows the variation of PV power (P PVON ), converter power (P M ), and total power (P TOT ...Jun 10, 2024
- Vijay DeshpandeThe PV-pushback-effect with solar panels can control backup power and provide constant light output. Solar day lamps (SDLs) are made by simply connecting an LED array to a solar photovoltaic (PV) panel. SDLs represent a highly cost-effective way of ...Jun 6, 2024
- Nick CornfordWhile an internal, rechargeable lithium battery is usually the best solution for portable kit nowadays, there are still times when using replaceable cells with an external power option, probably from a USB source, is more appropriate. This DI shows ...May 28, 2024
- Stephen WoodwardSelf-heated transistors used as thermal air flow sensors are a particular (obsessive?) interest of mine, and over the years I must have designed dozens of variations on this theme. Figure 1 illustrates one such topology seen here (Reference 1) ...May 27, 2024
