HJSplit (Software for Splitting and Joining File)
HJ-Split is a software that can be used to split and join a file with very easy steps.
How to split files:
1. run HJ-Split and select Split
2. select the file you want to split (input file)
3. specify the location of the...

555 Timer Chip
The 555 timer chip is probably the most versatile non-programmable part I have ever seen. Over the past 40 years, many people have created at least hundreds...

Metronome
A metronome marks time by producing a regular sequence of "clicks" or "pocks". Adjust the click rate by adjusting R2 or changing C1's value. That will varying the RC time constant so it will also varying the "delay...
Light Flasher
This circuit produces bright flashes every second or so. R1 controls flash rate. L1 can replace with 3V or 4.5V flash light or for simply you can use a LED for example.

Zener Voltage Regulator
This circuit supplies a steady voltage (Vout) to a load from an unregulated supply (like a battery), Vin can vary but must be at least 1 volt above desired Vout. I, can vary from 0 mA...
Voltage Doublers
These circuit approximately double an incoming AC voltage. The output is DC. Use capacitors and diodes rated for twice the input voltage. Output ripple can be reduced by using large values for C1 and...

Binary Subtraction
Half subtractors and full subtractors will be explained in this section. The rules for the binary subtraction of two bits are given in Fig. 1. The top number in...
Binary Addition
Adding binary numbers is a very simple task. The rules (addition tables) for binary addition using two bits are shown in Fig. 8-1. The first three rules are obvious. Rule 4 says that, in...

Combinational Logic Circuit
Multiple gate functions can be combined to form more complex or different Boolean logic functions. Wiring together multiple gates are used to build a complex logic...
Logic Gates
Various forms of logical building blocks are available in integrated circuit form. These logical building blocks are called “gates,” with each gate having a distinct...
Introduction to Digital Electronics
Digital electronics is a large branch of the electrical-electronics field relating to those electronic functions used in performing logical functions. It encompasses every type of logical system from simple combinational logic control in a coffee pot...
