5 Simple Electronic Dice Circuits Explained [Digital Dice]

Last Updated on May 21, 2026 by Swagatam 12 Comments

dice compressed

We all know what a dice is and how manually a dice is shuffled and thrown to get a random number. In older times when we did not have computer games or mobile games, we used to play with various indoor games that required tossing a cubical thing called dice having 1 to 6 dots […]

buckboost

In this post I have explained s few simple DC to DC buck-boost converter circuits which can be used for either stepping up the input DC voltage or stepping down the input DC voltage to specific output DC voltage levels. Since a buck-boost converter allows the input voltage to be either stepped up or stepped […]

Load-Line Analysis in BJT Circuits

Last Updated on May 20, 2026 by Swagatam 1 Comment

So far we have been studying BJT analysis dependent on the level of β over their corresponding operating points (Q-point). In this discussion we will check out how a given circuit conditions can help in determining the possible range of operating points or Q-points and in establishing the actual Q-point. What is Load Line Analysis […]

How to Troubleshoot Transistor (BJT) Circuits Correctly

Last Updated on May 20, 2026 by Swagatam 9 Comments

checking DC level of Vbe

Troubleshooting BJT circuits is basically a process of identifying the electrical faults in the network using multimeters across the various nodes in the circuit. BJT troubleshooting techniques is a huge topic and therefore including 100 % solutions and strategies can be perhaps difficult within a single article. Basically, the user should know about a handful […]
