I found this DIY synth kit on a site called "Tech Will Save Us".
Using this kit you can create 3 different types of synths.
With the items found in this kit you can create a Dub Siren Synth a stutter synth and a Atari synth.
Each synth has it strengths and weaknesses but they all create unique and interesting sounds
If you want to make a track like the one seen below you will have to pitch the sounds to a note so that you are able to place them on a keyboards as the 'DIY SYNTH" doesn't have any set pitch control to a musical scale.
These files can be imported into a sampler and then played on a keyboard
Example - Using Ableton live lite included instrument "Simpler" or Logic pro's EX24 instrument.
