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...

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...

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...

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...

Low-power, low-noise Analog Devices ICs and Intel MAX 10 FPGA in compact 86.5mm x 25mm outline Analog Devices and Arrow Electronics have worked with Trenz Electronic GmbH to produce three ready-to-use data-acquisition platforms that relieve the design and electronics manufacturing...

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...

Tektronix brings many of the key features loved in classic curve tracers to Keithley SourceMeter source measure units (SMUs) with the release of its Keithley I-V Tracer software. Tektronix introduced the industry’s first curve tracer in 1955 to display characteristic curves for vacuum...

Adil Malik build his own injection transformer to test switchmode power supplies in his lab. He writes: Recently, I have been designing some SMPS and required some hardware to measure the actual loop response of the complete converters. People familiar with this area will probably know...
