The innovation of equipment for calamity detection and monitoring are quite rampant. It is because of consecutive aggression of storms and earthquakes in different parts of the world. As to observe the different scenarios, these are not merely natural causes, there are some or most of it is manmade. A good example of it is […]

Thin LED strip but also a powerful LED application sourced directly from 230V mains line are no problem for Wago series 2059, 2060 and 2061 terminal blocks. Innovative series Wago 2060 now has two new familiar – smaller and bigger one. We talk about series 2059 and 2061. In result, WAGO 2059, 2060 a 2061 […]

This chimera is a microcontroller emulation of a UK101, an 8-bit microcomputer from the early 1980s. Needless to say I had one; it is a shocking thirty-three years since, as a spotty teenager, I soldered one together over the course of a few days. I recall the kit cost the equally shocking sum of £99.95 (a lot of pocket-money), and […]

We recently had a customer present this faulty Alchemist Forseti integrated amp for repair – I’d guess this dates from the 1990’s and has been well looked after. It’s a bit of a bruiser as you can see from the extensive heatsinking! Unfortunately it developed a DC fault on the loudspeaker outputs and destroyed the […]

The PIC 18 PIN (DIP) Development / Evaluations Board demonstrates the capabilities of Microchip’s 8-bit microcontrollers, specifically, 18 Pin PIC16F1847. It can be used as a standalone demonstration board with a programmed part. With this board you can develop and prototype with all Microchip’s 18 PIN PIC microcontrollers. The board has a Reset switch and […]

As if smartphones can’t already do enough, soon they may be able to scan three-dimensional objects and send the resultant high-resolution 3D images to a 3D printer that produces hyper-accurate replicas. This comes thanks to a small and inexpensive device called a nanophotonic coherent imager (NCI), which was developed by scientists at Caltech. The NCI […]

It´s surely not necessary to remind that any device can fail. Failure of a component, overload of a component (underestimated sizing), external influence and many other reasons are daily causing failures of devices. If the result of a malfunction is only an intermediate shutdown, it´s let´s say a better case. But if a device malfunction […]

This design features a low power wideband RF synthesizer that is used in GSM receiver cards. It has dual differential and open drain outputs with frequency range of 34.375MHz to 4400MHz(in continuous range). The logic compatibility is 1.8V while the system is running on a single 3.3V supply. It has -143dBc/Hz Phase Noise (PN) performance […]

The dramatic rise of smartphones, tablets, laptops and other personal and portable electronics has brought battery technology to the forefront of electronics research. Even as devices have improved by leaps and bounds, the slow pace of battery development has held back technological progress. Now, researchers at UCLA’s California NanoSystems Institute have successfully combined two nanomaterials […]
