Electronics Lab Cable Hanger Sorts Things Out
If you have a bunch to test cables lying around, you can easily organize them with a proper lab cable hanger. If you have a 3D printer, just make one. Read more
LCR-T4 Component Tester – Good Stocking Stuffer
Did you find an LCR-T4 Component Tester in your Christmas stocking this year? At around $10, it’s a pretty neat gift for electronics makers. Read more

Download your free LTSpice digital breadboard and have some fun learning electronics. Test and understand your ideas before you actually build something. Read more
La Crosse Wireless Weather Station
Last summer, we replaced our La Crosse Wireless Weather Station with a new model, this time in living color. Works great and looks good. Read more
Wideband Loop Transimpedance Op Amp Selection
You can select candidates for a wideband loop transimpedance op amp by reading data sheets and simulating performance in LTSpice. Read more
Wideband Loop Antenna Implementation Begins
Enough theory. It’s time to start the wideband loop antenna implementation using real parts and circuits. Read more
Loop Amplifier Input Impedance – Keeping It Low
Popular circuits do a pretty good job of providing low loop amplifier input impedance. This means you can use these to keep a loop in short-circuit wideband mode quite easily. Read more
Andonstar ADSM201 Digital Microscope – Merry Christmas
Merry Christmas, John. An Andonstar ADSM201 digital microscope for SMD work. And looking at tiny bugs with the grandchildren, too. Read more
Loop Current-to-Voltage Converter – A Short Story
A transimpedance amplifier provides a near perfect loop current-to-voltage converter. It provides lots of gain while keeping your loop in wideband or short-circuit mode, which is what you need. Read more
