A digital dice using 74LS47, 74LS90 and seven segment display

Posted on June 16, 2020July 18, 2021 by kitstvcom

This is a different type of digital dice. We have previously seen electronic dice with 7 LEDs. In this project, we have a seven-segment display, not LEDs.

When you press the tactile switch the numbers increase from 0 to 9, and when the switch is released it stops at a random number. Using the 2 jumpers, you can display the numbers from 0 to any number, for example, from 0 to 1 or 0 to 5 or 0 to 8 or 0 to 9.

NE555 and CD4017 electronic dice DIY Kit

Posted on June 16, 2020December 16, 2020 by kitstvcom

This is yet another CD4017 and NE555 based digital dice with 7 LEDs. When you press the tactile switch, the LEDs start flashing and stop with a pattern that represents a number between 1 to 6 like real dice. The display will always random.

How to build Jaycar’s electronic dice DIY Kit KJ8222

Posted on June 16, 2020November 8, 2020 by kitstvcom

This is yet another digital dice DIY kit from Jaycar. This kit is good for electronics beginners and extremely easy to build. Basic soldering skills should be enough to build this kit.

The video shows all the assembly steps. After assembly, simply press the red button and wait until you will see the set 7 pcs LEDs working as a dice. It requires a 9V battery.

Remote operated musical bell DIY Kit

Posted on June 16, 2020June 18, 2020 by kitstvcom

Remote operated musical bell is one of the interesting experiments every electronics hobbyist would like to make. We have made a very simple remote-operated musical bell DIY kit that requires your half an hour labor to make it work. It uses CD4017 decade counter, UM66 or BT66 musical chip and TSOP4838 infrared sensor as its important components.

DIY Arduino Kit with ZIF socket

Posted on June 16, 2020June 16, 2020 by kitstvcom

It is just another ‘build your own Arduino’ project. BuildCircuit has worked on similar projects before. The most popular project is a DIY Arduino kit. The DIY Arduino looks similar to the real Arduino boards and uses an FTDI basic programmer to program the chips.

The kit that we are going to work on this article is also a DIY Arduino. It comes with a zero insertion force (ZIF) IC socket. You can simply insert an Arduino chip and program it. The board has a header to connect an FTDI basic module that can be used to program the Arduino chip.

A basic multivibrator using 2 transistors

Posted on June 16, 2020June 16, 2020 by kitstvcom

This is a simple multivibrator kit using two transistors(S9014), two capacitors, and a few other components. The working principle of a multivibrator has been explained in previous posts also. You can read about the multivibrator circuit on this page.

The two LEDs on the PCB flash alternately, that’s all you see on the circuit board. It is a very basic electronic kit for electronics beginners.
