‘Soldering’ with a laser
https://www.electronics-lab.com/soldering-with-a-laser/
Thijs Beckers @ elektormagazine.com writes about a new experimental method of connecting electronics components together using a laser beam. Researchers from the University of Saarland have, together with colleagues from Helsinki, discovered a new material which can connect electronic components together using a chemical method. Multiple very thin layers (1000x thinner than a human heir) […]
Improved Arduino Rotary Encoder Reading
https://www.electronics-lab.com/improved-arduino-rotary-encoder-reading/
Here is a nice tutorial on how to use rotary encoders with Arduino. Example code is included. I wanted to use a low cost rotary encoder as an input mechanism for one of my upcoming projects and was initially bewildered by the code options available to take readings from the rotary encoder and determine how […]

NeuroBytes Simulate Dendrite to Axon Input/Output
https://www.electronics-lab.com/47980-2/
Zach Fredin and Joe Burdo has designed an electronic neuron simulator to help educate students of neuroscience. NeuroBytes are tabletop electronic neuron simulators designed to help students understand basic neuroscience concepts. The platform consists of modular elements that can be freely connected to form biologically representative networks, and has been built from the ground up […]
Building a simple Circuit Probe
https://www.electronics-lab.com/building-a-simple-circuit-probe/
Vicente Jiménez has published a new project. It’s a circuit probe that gives an indication when a node is floating or driven logic high or logic low and can also be used as a continuity tester. He writes: Sometimes you need to check one circuit and test some of its nodes. Usually a tester in […]
Low voltage power supply
https://www.electronics-lab.com/low-voltage-power-supply-unit/
Dilshan Jayakody has build a low voltage power supply that is able to provide four outputs: 1.5V, 1.8V, 2.5V and 3.3V. This power supply can be used to power low voltage mcus, CPLDs and analog ICs. He writes: In this post we introduce simple and flexible, regulated low voltage power supply unit. This power supply […]
