8 GHz Sampling Oscilloscope for experiments

A basic open-source multi-GHz sampling oscilloscope for experimenters on a budget. Still a work-in-progress, with key pieces on separate PCBs, but showing bandwidths in the 7-8 GHz range with >= 100 GSa/s equivalent-time sampling, and around 500 k comparisons/second real time. by Ted...

Low cost high accuracy STM32 FFT LCR meter

Adil Malik made a low cost FFT LCR meter with an STM32 MCU: The approach I took was a mixed signal one where a capable analog front end would be paired up with a beefy DSP processor to compute the Impedance. Most importantly, in this scheme, the DSP is responsible for discriminating...

Free Elektor Article: Improved Radiation Meter

Author: Burkhard Kainka All that’s required to measure radiation is a simple PIN photodiode and a suitable preamplifier circuit. We present here an optimised preamplifier and a microcontroller-based counter. The microcontroller takes care of measuring time and pulse rate, displaying...

Digital Caliper Computer Interface

Digital Caliper Computer Interface can be used to log data on a spreadsheet. Report by Jeremy S. Cook @ blog.hackster.io With a few pointers found here, he found that this data is transmitted in a continuous stream in 24 bits at 1.5 volts. He therefore level-shifted the 1.5V output to...
