Rediscover electronics as a hobby and link to this page for every circuit known to mankind. Unfortunately as we all know, links come and go, pages may become obsolete or links inactive without us having the time to amend. Also, most of these circuits have not been checked by us so we cannot be held responsible for their accuracy, working or your own safety. Never work on mains powered devices as a first project and always make sure you have an isolation transformer or GFIC (Ground Fault Interrupter Circuit) as added protection. As first projects go the safest is run from a PP3 (9V) battery or through a transformed regulated supply with current limiting. Do not attempt circuits which use thermionic tubes or valves as they require a substantial anode supply to be effective (upwards of 300V DC).

These are just some of the better websites on the web. Yes, I did Google it and yes I have browsed through the relevant pages.  ESP remains one of the best (my opinion) in terms of explanation and accuracy.  For another one, if you are an audiohead:

Nelson Pass DIY – well put together website which gives readers more insight into circuit design.

As most DIYers will recall, their first circuits may have been around audio or RF, possibly light flashers and buzzers. No matter which circuit you build or direction you take, think Voltaire, Ohm and Ampère, the pioneers of this exciting hobby (or profession). Students of electronics in the 1970s may possibly have had the best of both worlds, tubes (valves) and semiconductors. Semiconductors paved the way to microelectronics. Digital electronics is now an everyday part of our life but analog is just as important. Our senses are analog in that they can measure varying degrees of sound, touch, light etc.  Combining the two we build very sophisticated circuits, control our world.
