Pots water alarm circuit
The flowers in pots require watering, as relying solely on the observation of moist soil surfaces can be unreliable. To address this issue, a flower watering indicator has been developed. This circuit includes a field effect transistor (VT1), a second...
The FARA 2 meter amplifier project
This article discusses a 2-meter amplifier capable of delivering an output of 25-30 watts. Over 35 units have been acquired at a cost of less than $50 each in bulk. Photo A displays the final version of the circuit board,...
DC-Coupled Audio Amplifier circuit
Designs for audio amplifiers with DC coupling to the load are not frequently seen today, despite offering distinct advantages.
Audio amplifiers that employ DC coupling to the load provide several benefits that can enhance performance in specific applications. In traditional audio...
ProfiLab-Expert 4.0
The ProfiLab-Expert software allows you to develop your own digital or analogue measuring technology projects. It doesn't matter if you want to create analogue measurements or digital controls - you can realize it all. And for all this you don't...
Tv-audio-amplifier
The amplifier captures the audio output signal from the TV and amplifies it to drive a set of earphones for private listening. It is constructed using an LM324 quad operational amplifier and an LM386 low-power audio amplifier. The circuit employs...
Load Cell Amp
A conventional 250-pound tension/compression load cell (LPU-250) based on a 350 Ohm strain gauge bridge has been acquired. A simple DC-accurate amplifier is being constructed to convert the low-level output of the strain gauge into a 0-5V signal suitable for...
Advances in Measurement & Sensor Tech
This issue features articles on various measurement and sensor-related embedded design projects. Readers are encouraged to attempt similar projects and share their results. Starting on page 14, Petre Tzvetanov Petrov describes a multilevel audible logical probe design. Petrov notes that...
Amplifiers connecting Bridge
This is a circuit that ensures that you can connect two amplifiers together so you get more power. When called in bridge linking two amplifiers plus you can link the outputs of the amplifiers to the speaker. One of the...
Stabilized-amplifier
This amplifier operates across a broad range of gains, typically from 1 to 10. It integrates the LT1010 with a fast discrete stage and an LT1008-based destabilizing loop. Transistors Q1 and Q2 create a differential stage that converts to a...
