Using the ICL8038 IC, this kit allows you to create a function generator that can create sine waves, square waves and triangle waves. You can adjust the potentiometer for vary the frequency from 200Hz to 2kHz. Play with the other two potentiometers to adjust the duty cycle and adjusting the offset of your signal. This kit is aimed for helping students or beginners in electronics solder their second through-hole board.

This kit is a simple soldering practice board, the goal is to build a digital clock! Using the Abra Kits guideline we have streamlined the manual to offer at most a schematic diagram, a parts list and basic soldering guide. This makes our manual ideal for classrooms who want no non-sense straight forward guide. This clock has two alarms and on digital clock, when powered off the settings will be reset.

Challenge yourself to create one of the most difficult things to make an LED Cube. The hardest part of this design is the backside which compose Surface mount components that need to be soldered into place! After mounting the components using either a soldering iron or Hot-air Rework Station, you have to flip the board and attempt to solder an array of 3x3x4 LEDs. Following our guide offers a good practice and verifications of your skill!

Build your own amplifier board that can control the bass, treble and volume! Works great with 4 to 8 ohm impedance speakers. Tested with our 5 watt speaker. All you need is a transformer, some 3.55mm audio source input and your speakers for the output. A rough estimate of 30 minutes soldering work is required to construct this kit. The two channels can deliver a max of 15 Watts thanks to the beefy heatsink. If you are looking for a preassembled and straight out the box functionality please look for “MOD-AMP”.

Typically this unit has 16 pinouts that requires a breadboard to interface with any microcontroller and a 10k potentiometer to adjust the contrast value to reduce the backlight and view the text. However with the addition of the I2C Backpack pre-soldered you only need to connect four pins to your microcontroller. You do not need to worry about the 16 pin cables that need to be connected and the unit comes with a potentiometer to adjust the Contrast. You also have a jumper for two pins to enable or disable brightness.

Simply follow the basic manual or skip to the schematic diagram and assemble this led Ripple/Flash board based on the 555 timer and CD4017BE IC. Reuse the ICs for creating other circuits such as a follower using a LED Vu Meter on breadboard. Hack the board to create a Night Rider Circuit or anything else you might want to use for the future, the system should be fairly easy to assembly and offers a functional circuit which will also demonstrate if your soldering skills have improved.
