The automotive products are quite recognized nowadays. It brings high demand on automotive chip and other related electronic devices. These demands are diverse, which brings difficulties to automotive developers. In this design, users are provided a modifiable firmware using In-System/In-Application Programming (ISP/IAP) via USB. It features the Vertical Alignment (VA) Chip-On-Glass (COG) display module with […]

This unit provides 4 autonomous MIDI inputs and 1 MIDI output. Note this is a ‘proper’ MIDI Merger – all 4 MIDI inputs can be used at the same time, unlike other ‘designs’. The unit also provides an indication of the channel number being played, and has shown itself to be capable of expansion into […]

By Stephen Evanczuk Contributed By Hearst Electronic Products 2015-01-28 Microinverters provide an effective solution to solar-energy harvesting by providing power conversion at the individual panel level. The emergence of highly integrated MCUs offers an attractive approach to microinverter design, providing an option that reduces the cost of complexity which limited widespread adoption of microinverters in […]

A device operates OK until it reaches stable operating temperature … a typical situation in praxis usually caused by a faulty component or faulty (cold) joint. Localization of such a fault is easy only if we can cool down (locally) a given component or a given joint. It´s often possible to suppose a source of […]

If the piclist is an any indication the 16f877 seems to be the new favorite hobby microcontroller, a position that used to be occupied by the 16f84/16c84. Compared to is older brethren the 16f877 has much more to offer at around twice the price. As for all Microchip controllers the datasheet (pdf) and the MPLAB […]

For the first time in 60 years, a new higher-performance semiconductor technology is less expensive to produce than the silicon counterpart. Gallium nitride (GaN), has demonstrated both a dramatic improvement in transistor performance and the ability to be produced at a lower cost than silicon. GaN transistors have unleashed new applications as a result of […]

Described here is a low-component count Emergency Vehicle LED Light circuit which can be used for capturing the attention of (or warning) drivers and pedestrians. These type of lighting gadgets kindle an instant response that makes people look up and pay attention -an important consideration when a matter of moments can mean life or death […]

I started playing with electronics back when I was 10 years old in Argentina, where I grew up. Then I got my ham radio operator license when I was 16 years old and I was very active in the ham club and on the air. It was then when I built my first vacuum tube […]

Over the last year I’ve been working towards an underwater sonar system for ROVs and surface boats. In order to learn the basic signal processing required to detect the echoes, I initially got a simple sonar working in air with a desktop conferencing USB speaker/mic running on Windows. A writeup, including source, is here. That article […]
