Take a random LM285Z 1.24V 1% part. Select a 124K 1% resistor and select a 2.37M 1% resistor from nominal population by measurement, each one to 5 digits. Goal is to get 25V as close to 0.1% as possible. ASS-u-ME one measures...
I have a TRUE RMS DVM.Hooked it in parallel with a digital scope to thefunction generator at 60 Hz.At zero offset, the DVM reading tracks the scope RMScalculation for sine/square/triangle waveforms.The scope knows how to measure the RMS...
Hi,ich bräuchte mal von den Mikrocontroller-Auskennern hier eine Einschätzung zur Machbarkeit des Folgenden:Gegeben sind diverse Uhren auf AtMega 168 Basis - konkret die "Ice TubeClock" [1] und die "Monochron" [2]. Dummerweise geht...
I generally avoid Maxim, after some bad experiences ("we never obsolete parts", says the Maxim outside sales guy. "we'll ship you some as soon as we get enough orders to do a fab run", says the Maxim inside-sales girl.)But those...
Hallo, sind eure Eier schon wieder aufgetaut? Aber die eigentliche Frage ist folgendes: Wie justiere ich mein Digitalvoltmeter vom Flohmarkt? (Sieben euro) Das DT9205A hat 3 Potentiometer und diese Vorschrift: VR1: Gleichspannung im 20...
I'm interested in making a load cell scale using an Arduino so I can program special features that currently available scales don't have.Any thoughts on best way to get high resolution data to an Arduino microcontroller board?AD7730 chip,...
