Schematics of delabs: Precision Op-Amp Current Source
http://schematics.dapj.com/2009/02/precision-op-amp-current-source.html
Electronic Circuit Diagrams and Design Ideas. Thursday, February 19, 2009. Precision Op-Amp Current Source. In this circuit we tackle the error indicated in the earlier Current Source. The LM336-2.5V eliminates the tiny error of the regulated supply and resistors. Thereby increasing Precision to a higher degree. Suppose you build it with the best Opamp, FET etc., but place it close to a Warm transformer, Regulator chip or even a Cooling Fan, you will see the lower digits of a 5-1/2 DMM spinning fast.

http://schematics.dapj.com/2008/04/flashing-mains-neon-lamp.html
Electronic Circuit Diagrams and Design Ideas. Tuesday, November 10, 2015. Flashing Mains Neon Lamp. Here is a Neon Flasher circuit (untested) for a user request at Elex Quna. This can be built into a switchboard or a gadget for indicating Live Power. See more of my Home Made Circuits. Oh, i will put the probe it in 10M mode" will not do. The ground clip of the probe goes to Electrical Earth which is 'connected' to Neutral in the mains wiring. So you put the earth crocodile clip on the live point&...For t...
Schematics of delabs: Battery Level Indicator
http://schematics.dapj.com/2004/10/battery-level-indicator.html
Electronic Circuit Diagrams and Design Ideas. Saturday, April 11, 2015. This circuit uses a LM339, a quad comparator. LM339 can work on single or dual supplies, it has a open collector output that can drive 15mA, low power consumption. The circuit is an untested design but it should work. I did it as many searches were made in my webpages with these keywords. Mains Voltage and Power Circuits. Similar circuits for Mains Voltage Monitoring. Comparators in Interface Circuits. Simple Sample and Hold. This is...
Schematics of delabs: Battery Backup for SRAM or Microcontroller
http://schematics.dapj.com/2006/10/battery-backup-for-sram-or.html
Electronic Circuit Diagrams and Design Ideas. Monday, February 15, 2016. Battery Backup for SRAM or Microcontroller. This circuit can be used as a low cost SRAM and Microcontroller-Microprocessor Battery Backup. All the diodes are 1N4148, The diodes prevent battery discharge back to power source. D8 gives a one way path to charge Battery thru R13 which limits current. D4 ensures a one way path of supply to chip when power is present. D5 is backup supply on power failure. Microcontroller in Process Control.

Soldermans Basic Electronics: Fluid or Water Level Indicator with Reed Relays
http://solderman.dapj.com/2004/10/liquid-level-measurement.html
Tutorials, Circuits, Explanations, Theory, Fundamentals. Tuesday, September 09, 2014. Fluid or Water Level Indicator with Reed Relays. This is a way by which you can monitor the level of fluids like water in a tank. Based on data from the sensor you can control things like solenoids or motors as required or even turn on a buzzer, hooter or annunciator in a control panel. When the fluid level changes, the float moves up or down with it, when the float moves over a section of pipe where the reed relay is m...

In Test and Measurement and Industrial Process Control a common factor is instrumentation. The measuring aspect is common to both. T&M instruments are used in Testing, Research,Automated Testing, Troubleshooting and Servicing. On-Off controls or level trip relays can oscillate if hysteresis dead band is very small or absent. LF356, TLO71 and CA3140 are FET input Op-Amps, the bias is ...
Soldermans Basic Electronics: Thermocouple Temperature using DPM or DMM
http://solderman.dapj.com/2009/01/thermocouple-temperature-using-dpm-or.html
Tutorials, Circuits, Explanations, Theory, Fundamentals. Tuesday, January 06, 2009. Thermocouple Temperature using DPM or DMM. If wires of two dissimilar metals are joined at both the ends and the junction formed at one of the ends, is heated more than the other junction, a current flows in the circuit due to Seebeck thermal emf. This effect is used in thermocouple temperature sensors. Temperature in Deg C. As cold junction is not zero but is at room temperature (RT) add RT to temperature. In the circuit...
