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 14- Jaycar’s ‘Jiminy The Cricket’ project
This post shows how to build Jaycar’s JIMINI THE CRICKET DIY KIT- PROJECT SC2 #14. It takes around half an hour to build this kit. It is basically a sound sensor.
When there is a noise/sound close to the electret microphone, the circuit turns on the two LEDs and produces a chirping sound. (more…)
DIY KIT 13- Jaycar’s Skeet Shooting Game DIY Kit
This is the “Skeet” Shooting Game Project from Jaycar. The kit checks your hand and eye coordination. There are 9 green and 1 red LED. There are two switches: one is reset switch and the other is FIRE switch. (more…)
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.

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.
