Capacitor Charger Lead Acid Battery
Leaving aside the complex chargers, "stuffed" electronics capacitor charger is one of the best connections. Charging current is limited by the resistor (or other element of the changing excess energy into heat), but the reactance of the capacitor to the...
MePADS
If you are considering building the Desert Ratt 2, it is advisable to read all the accompanying text, as it contains relevant construction details. Engaging with the comments and replies can also provide additional insights, as previous blog posts have...
Power supply circuit design
C1 is a 1000 microfarad aluminum electrolytic capacitor. For loads less than 100mA, a 220 microfarad capacitor can be substituted. The voltage rating should be 2.5 times the output voltage.
C1 serves as a critical component in various electronic circuits, particularly...
Simple Capacitor Tester
An LM3909 LED flasher functions as an oscillator, with the frequency determined by the capacitor connected to its terminals. The LED can be utilized to visually count frequency using a stopwatch for large capacitors (C > 500µF).
The LM3909 is an...
Apply a Pulse to a Speaker Using a Capacitor
This project demonstrates how a capacitor can supply a pulse signal to a speaker. A capacitor is charged and then discharges its voltage to a speaker, which acts as a transducer that converts electrical signals into sound. The result is...
Field, Crystals and capacitance meters schematics
Because it uses few parts, a printed circuit board is not necessary; components can simply be soldered to one another. However, a box is desirable for operating convenience. The case and aerial from a discarded toy walkie-talkie was used in...
Car Large capacitor charge controllers
One-farad capacitors require some care. It's common knowledge that they must be pre-charged with a current-limiting resistor before plugging in. It is less common knowledge that those fifty-dollar smart cap controllers are in fact very simple devices, two dollars for...
Help with a schematic please
A project is underway to construct the CountryHick DI as illustrated on DIYFactory, incorporating a few minor modifications. The final design aims to be a 1U unit with four inputs.
The CountryHick DI (Direct Injection) box is a crucial tool in...
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...
