Electronics lab electrical power

Here are some tips how to arrange electrical power distribution on a small electrical lab (for example home lab). Grounded power outlet: The power that comes to your electrical lab should be grounded for your safety. Most everyone has 3-prong electrical outlets in their homes, with the third prong being called the “ground.” Extension cords

Playing with high end oscilloscope

Playing with an oscilloscope you’ll (probably) never own article tells that Hackaday staff were really jealous when [Shahriar] a video he made, in which he casually explains how a $500,000 160GS/s 62GHz oscilloscope works and then starts playing with it. Looked interesting do I thought to link it to my blog as well. Experiments and

USB Fume Extractor Idea

USB Fume Extractor project combines a small craft box, 12v case fan, aquarium carbon filter, dc boost converter and some basic electronic components to create a USB powered fume extractor which treats your lungs to some clean air when soldering. Check the USB Fume Extractor video how the project works: USB Fume Extractor was designed

Fiber-optic testing

Fiber-optic testing: Keeping it simple in the field article tells in the telecommunications industry today, testing is one of the most confusing and misunderstood phases of installing a fiber-optic system. While misunderstood, optical-fiber testing is one of the final and most important procedures in installing optical networks.

EMF measurements

An electromagnetic field (also EMF or EM field) is a physical field produced by moving electrically charged objects. It affects the behavior of charged objects in the vicinity of the field. The electromagnetic field extends indefinitely throughout space and describes the electromagnetic interaction. It is one of the four fundamental forces of nature. EMF measurement

Open Logic Sniffer software and hardware

Logic Sniffer Java client is an alternative OLS-client provides a software client for the Open Bench Logic Sniffer logic analyser hardware (that is based on ideas from open source SUMP analyzer). Software works also with SUMP compatible devices and Bus Pirate hardware. When tested with the demonstration data the software seemed to work quite well

Measuring pictures with software

Reverse engineering salvaged part footprints article mentioned an interesting idea to use a microscope software to process an image of the board. Measuring with Software article mentions an interesting free computer-based microscopy software MiCam. MiCam software allows (once you have calibrated it) you to draw more lines on the photos and calculate and display the

Debugging RS-232 with logic analyzer

RS-232 serial interface is still quite widely used in many applications. Usually RS-232 Mini Tester with LEDs for indicating state of different signals is all that is needed to make things work. But sometimes seeing signals with your eyes is not enough for troubleshooting and testing. There are nowadays cheap logic analyzers (like Saleae Logic
