Improve your Photodiode-Based Radiation Meter
In the ever-changing world of electronics, not many applications remain valid after eight years, but there are exceptions. One of them is the photodiode-based radiation meter we published at the end of 2011. Because the original design has suffered slightly from component obsolescence, we decided to refresh it a bit and replace the BF245 by a BF256B. We also did some other useful modifications.
