Free Fresh Article: Capaci-Meter
With the compliments of the Elektor Labs and Editorial teams, here comes another fresh-out-of-the-lab article that's free to download by all registered Elektor e-zine readers. "Free Fresh Articles" are published at two-weekly intervals in the Elektor e-zine, alternating with "Free Back Articles". This time we have a DIY capacitance meter that’s remarkable for its accuracy, low cost and beautiful PCB design. It has a two-digit Dekatron-style display made from discrete LEDs, and zero (0) microcontrollers inside, yet achieves 5% accuracy across its range of 200 pF to 9.9 uF.
