This is a first in a series of stories called “EEvolution of an idea” showing how a good idea got its start and evolved into a viable product in the electronics industry. I would ask our faithful EDN readers to comment on this series idea and if there is a good positive response which views […]

I just happened to see some large strips of LED lighting when I was picking up some parts at Maplin which were on sale (if I remember correct they were around £12 per approx. 2m strip) however the controller/driver was still around £40, so I thought I would just build a better one myself. I

This Instructable will demonstrate the building of a bare bones (and really inexpensive… less than $5) Arduino compatible module that can be put together on a small piece of stripboard and can be used either on a breadboard or independently. The following links / similar projects were used as inspiration: * http://www.instructables.com/id/Small-form-factor-DIY-Arduino-on-stripboard/ * http://tinkerprojects.blogspot.com/2012/06/minimal-arduino-on-small-stripboard.html * http://shop.moderndevice.com/products/rbbb-kit * http://txapuzas.blogspot.com/2010/07/paperduino-stripboard.html The

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
