This is useful tip for anyone making or using surface mount components on PCBs. It relies on access to a laser cutter, so if you don’t have one, look away now….. I cut a plastic stencil on the laser, align it with the PCB pads and then squeegee a thin layer of solder paste through […]

All items stored in a deep freezer will thaw out if, for some reason, the temperature inside the freezer rises to the thaw point. However, a freezer monitor alarm can warn you of the rising temperature before the thaw point is reached. This simple circuit is powered by regulated 9V and built around a few […]

panStamp was one year old in June but we forgot to prepare a decent celebration… To be honest, we were thoroughly working on our new line of wireless modules so we preferred to postpone the party. OK but, what do we have up our sleeves? It’s not a secret, we were creating a new panStamp with all […]

A while back I picked up a SparkFun 128×64 LCD and an Adafruit 66-channel GPS module to have a go at making a GPS clock.The great thing about setting the time and date via GPS is that I won’t have to put any buttons on the clock. It’ll set itself, and appear to be completely […]

I’ve been an electronics hobbyist for many years, so I’ve used and even built my share of resistance decade boxes. Each one consisted of rotary switches with labels identifying a different power of 10 for each switch. You “dialed up” the desired resistance by turning the appropriate knobs to add up to the target resistance […]

Semtech has launched the SX1272, the first product in a new family of long-range Radio Frequency Integrated Circuits (RFICs) with a transmission range up to 15 kilometers. The SX1272 integrates Semtech’s new LoRa (long range) modulation technology to enable drastic range improvements over alternative modulation methods. Compared to a typical range of 1 to 2 […]

Double PCB terminal blocks of the PDSV series from company Euroclamp enable to better utilize a space and to connect more leads on a small area. If we need to connect several leads on one side of a PCB and we can´t or don´t want to use terminal blocks with a smaller pitch, then the […]

Before like two years when I got my first Ladybird toy, I was thinking it will be great if I can charge those wirelessly, without changing the battery. Yes, it is charging very slow, yes it will add some weight, but it will be cool. QI standard is going forward, and there is already some […]

Potentially, headphone listening can be technically superior since room reflections are eliminated and the intimate contact between transducer and ear mean that only tiny amounts of power are required. The small power requirement means that transducers can be operated at a small fraction of their full excursion capabilities thus reducing THD and other non-linear distortions. […]

These recent breakthroughs in electrical component technology are likely to have a significant impact on the electronics industry – and on people’s everyday lives. Graphene – Latest News for Revolutionary Material Your’e probably aware of the superstar conductor of the future, Graphene: “A wonder material that is the world’s thinnest, strongest and most conductive material […]
