ATtiny814 Power Analyzer
Not sure there is anyone on the internet who loves the Attiny series of microcontrollers as much as Stefan Wagner. We have explored a number of projects from him, from the USB power tester to the TinyRemote with ATtiny13, all based on a member of the Attiny series of microcontrollers....

Power Meter gives accurate Measurement For energy Consumption of IoT devices
In the world of today's technology, the Internet of Things is very popular. We see that most of the devices used to create the IoT (Internet of Things) function on small batteries or energy harvesting. We find it quite hard measuring the amount of energy being consumed by these IoT...

BPW34 Gamma Ray Detector
The usual approach to radiation detection is the use of a Geiger-Müller tube and its high voltage circuit requirements, but during a quick surf through the internet today, I came across this portable and "accurate looking" solution developed by Stefan Wagner, on EasyEDA. Rather than...

DIY voltage and current reference
Petteri Aimonen designed and built his own voltage and current reference: When developing a data acquisition system, I ran into a need of having fairly accurate current reference to compare against, 0.1% accuracy or better. This is not a particularly high standard, but unable to find a...

Free Elektor Article: Current Transformer for Oscilloscopes
Commercial current clamp devices certainly are able to measure current by potential-free means but they are not suitable for capturing rapid alterations in current over time. In addition, many low-cost examples of these do not provide an output for connecting to an oscilloscope. Here...

Free Elektor Circuit – Acoustic IR Remote Control Tester
In this circuit we use the output signal from a standard IR receiver (IC1 in the schematic of Figure 1) to drive a miniature loudspeaker. The IR receiver from Vishay used here is available for various frequencies ranging from 30 to 56 kHz. A large number of IR remote controls operate...
