LCR meter - first results
11/12/12
Here my first update:
Got the analog part up and running.[more] Unfortunaltely I had to do some "bugfixes" & optimizations... Nevertheless, tests have proven that it supports up to 100 kHz test frequencies.
The low level stuff of the software is also d -
Cheap 'n good LCR meter (or RLC meter?) for SMD components
11/06/12
How often do I debug electronic circuits and have a lot of SMD components lying on my table. To avoid mixing up wrong values I usually throw them away.
Sometimes it would be handy to measure the values of SMD components.
Already quite some time ago I found a [more] nice device -
Homemade vortex flow meter
11/05/12
I have a selfbuilt ventilation system in my house, including a selfmade heat exchanger.
Of course I'm interesting to measure efficiency of the system, so I added temperature and humidity sensors to it and even realized a function that it only ventilates when the outside humidity is l -
dielectric absorption
11/04/12
I read in a book about an effect called "dielectric absorption".
Basically it is an effect that each capacitor has. Depending on the dielectricum it is larger or smaller.
When a capacitor is discharged the capacitor charges up again after removing the shortcut between the
