Here's the fancy, animated schematic:

These are all the electronic components required:

and these are all the mechanical components:

apart from these, a soldering iron, solder, heat source, fiberglass resin (and hardener) plus some lacquer and cleaning solvent - that is all that is required!

See http://home.clear.net.nz/pages/dandavies/index.htm for full assembly/installation details - or, alternatively you can watch this YouTube video showing the construction of a similar product which uses leaded components instead of surface-mount ones - and no PCB or diode is used either.

在下看起來像是安裝一個暗鎖.
安裝之後,必須碰觸這個東西,汽車的電源才會導通,之後才能發動引擎.
如同影片最後用燈泡測試,碰了之後燈泡就亮了.

若是暗鎖  那裝一個開關不是比較簡單
可能他訴求是觸碰吧
