The single most important factor in synth DIY is your skills. You'll need to be able to read and understand [[Schematics|circuit diagrams]], identify [[electronic component]]s, and [[fault-find]] non-working circuits.<ref name="ks">[https://web.archive.org/web/20170420052751/http://www.cgs.synth.net:80/help.html Help page] of Ken Stone's Modular Synthesizer site (archived)]</ref> The best way to learn is by building.

[[PAiA Electronics Inc|PAiA]] have been producing analogue synth [[kit]]s since 1967. The [[PAIA Fatman]] is a complete synth to build from a proven design. It has two [[VCO]]s and a good [[VCF]] similar to that of the second-series [[ARP Odyssey]]. The schematics are easy to follow and anyone is allowed to build it providing they don't market it as their own.<ref name="sos" /> There is a selection of links to bare [[Printed circuit board|PCBs]] and kits at [https://web.archive.org/web/20130530023107/http://www.cgs.synth.net/modules/index.html Ken Stone's Modular Synthesizer site].

Things changed when ETI, in conjunction with a company called [[Powertran]], released the design and a kit of parts for a single-oscillator synth called the [[Transcendant 2000]]. The article (by [[Tim Orr]], formerly of [[EMS]]) was well planned, and Powertran provided everything you needed, down to the last nut and bolt, even including a mains plug. It was very popular, and spawned a range of synths including the [[Transcendant Polysynth]], which was the kit-builder's [[Jupiter 8]] without the memories. In 1979 ETI also published schematics for the [[Digisound 80]] modular. This, like the Transcendant Polysynth, featured [[Curtis Electro Music]] synth [[chips]]. The CEM chips made kit building much easier.<ref name="sos" />
 
The Elektor [[Formant synthesizer]] design was published in 1977/78,<ref>[httphttps://web.archive.org/web/20070110103220/http://www.euronet.nl/~rja/Emusic/Formant/ ''Formant Modular Analog Synthesizer''] by Rick Jansen</ref> also modular and based around [[Moog Modular]] styling. Another early ETI design was the [[ETI International 4600|International 4600]] and its descendants, the [[ETI 5600|5600]] and [[ETI 3800|3800]] synths, which were distributed as kits by [[Maplin Electronics]]. The 4600 and the 5600 featured a [[pin matrix]] for [[Patch|patching]] similar to that of the [[EMS VCS3]], only larger. However, these synths proved overly complex for the amateur constructor.<ref name="sos" />
 
Bear in mind that magazine designs are frequently inaccurate or incomplete. The [[Practical Electronics Analogue Sequencer]], for instance, published in April 1977, will not function correctly without the modifications published in September 1977.<ref name="sos" />
