DIY KIT 27- CD4060 and LEDs music kit

This is a simple CD4060 based LED and music kit for beginners. The kit flashes the different color LEDs and plays monophonic music, that’s all. The CD4060BC is a 14-stage ripple carry binary counter. The counter is advanced one count on the negative transition of each clock pulse. The counter is reset to the zero state by a logical “1” at the reset input independent of the clock. (more…)

DIY KIT 26- 16×3 Audio spectrum DIY kit

DIY KIT 24- NE555 based piano kit

This is a very simple NE555 based electronic kit for electronics beginners. It is a basic piano kit. I have written a similar project article before on this website. You can see it here. The kit has been built in an astable multivibrator mode. Every press of the switches results in a change in resistance in the astable multivibrator mode circuit. (more…)

DIY KIT 23- CD4511 based seven segment display kit

This is a basic electronic kit for beginners and hobbyists. It has a CD4511 chip that is a BCD to 7 segment latch decoder driver. It is a very popular chip and used widely in seven segment display projects. You can send pulses to this kit (via NE555 or any other pulse generator) and the seven-segment display starts counting. It is an up counter which means that it does not count down. There are other up/down counter chips like 74LS192 which can be used along with CD4511 to make an up and down counter circuit. However, this kit cannot be connected to 74LS192 or any other counter chips. (more…)

DIY KIT 22- Rain drop sounder circuit using NE555

This is yet again a very simple astable multivibrator circuit using NE555. The circuit produces a sound that somewhat sounds like a raindrop. This is a very basic electronic kit project for electronics beginners and hobbyists. Anyone with basic electronics and soldering skills can build this easily. (more…)

DIY KIT 20- How to make a simple multivibrator

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. (more…)

DIY KIT 19- Remote Operated Musical Bell DIY Kit

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. (more…)

DIY KIT 17- DIY ZIF Arduino programmer

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.

DIY KIT 12- Hee-Haw Siren With Flashing LED

This video shows all the steps to build the HEE-HAW Siren Project from Jaycar. The kit is based on NE555 IC. The timer NE555 IC is configured in astable mode.

You will hear a hee-haw siren similar to an ambulance and you will see the two green and red flashing LEDs.

The kit is very much similar to BuildCircuit’s project: https://www.buildcircuit.com/light-activated-police-siren-using-555-timer-and-light-dependent-resistorldr/ This kit is good for electronics beginners and extremely easy to build.

Watch the video to see all the assembly steps:

DIY KIT 10- Jaycar’s Sound Level Meter Kit project

This is a sound level meter project from Jaycar. It is based on LM3915 chip. The kit displays the volume intensity via LEDs. It is a visual representation of the audio level.

For the maximum volume of an audio source, the yellow and red LEDs light up. For medium sound level, only GREEN LEDs light up. In the video, you will see all the steps required to build the project. (more…)

DIY KIT 9- Light explosion LED effect DIY electronic kit using LEDs, NE555 and CD4017

This is a basic electronic DIY kit for beginners. The kit generates a light explosion effect with several LEDs. The scrolling of the LEDs is controlled by CD4017 and NE555.

You can adjust the speed of the explosion using a potentiometer. You need basic soldering skill to build the kit. It takes about an hour to build the kit for beginners.

You will receive these components in the kits package: 

The final look/output of the kit after assembly:

DIY KIT 8- Happy Birthday LED Flashing DIY Kit using CD4060 and Music Chip

This is a basic electronic kit for beginners. The kit has few SMD component and few through-hole components. Because it has SMD components, it is recommended to use a temperature-controlled soldering iron to solder the CD4060 chip.

You need to set the temperature to 300°C, otherwise, you may burn the chip and the kit will not work. The kit has colorful LEDs and when the kit is turned on, you will see the Happy Birthday Music and flashing of LEDs go together.

You can adjust the speed of flashing of LEDs using the potentiometer. This kit gives you a lot of ideas about soldering through-hole and SMD components. You need to be careful while soldering the diodes, capacitors, LEDs and the buzzer because all these components have polarity. Connecting the capacitor in the wrong way will explode it.

Soldering of music chip is a bit tricky, so, you need to see the video till the end. You need basic soldering skill to build the kit. It takes about an hour to build the kit for beginners.
