Step 1: Preparation

Gather together the necessary components, materials and tools.... the images below show the necessary electronic and mechanical components - you'll also need some epoxy resin (about 5ml), some lacquer, solder and a few tools - more information can be found on my website - http://home.clear.net.nz/pages/dandavies/parts_materials_tools.htm

Step 2: Assembly

Assemble the components according to my slightly antiquated and long winded animated instructions written for electronics students - if it is not easily viewed on your display, it may also be viewed here home.clear.net.nz/pages/dandavies/instructional_animation.htm

Step 3: Test Your G-Spot

Picture of Test Your G-Spot
Apply +ve power to the anode of the SCR, connect a load to the SCR's cathode and then earth the load... now touch the G-Spot as well as earth at the same time and the load should operate... see schematic below....
 You could also install a hidden switch...

AMEN !!!!!!

I think this is a great idea. It would be even greater if the instructions were clearer. Maybe if the instructions were broken down into more steps and step by step photos including car installation... Perhaps add links for the parts. Make it simpler for non electrical folk who like to tinker. Thanks.

I am utterly confused. Are the only instructions inside your GIF, which leaves no possibility to pause, rewind, or fast forward. If you miss a step, the only thing you can do is restart the animation and watch the entire thing again. Is there a step by step part with photos that I am missing? I really want to make one, but your directions are the only ones I have found. After I started to watch the animation three times, I am afraid that I am going to miss something. It seems like a great idea, but I just can't follow it that fast. I am afraid to make one with the sole direction of that animation. Is there standard (i.e. a page of step by step) directions anywhere? All I can find is the YouTube video, which seems to be a different version.

hi whosdadog - this and the YouTube are the only versions that I'm aware of. Yes, the YouTube version is different - it uses leaded components - not SMD's - and there is no PCB or diode used. Maybe you could try capturing a few screen-shot's of the animation - the PCB image is probably the most important part. Hope that you manage to work it out.
Yeah, I tried to get the frames out of the gif, but PS would cooperate. The most confusing part is when the gif is showing to how to lay out the components. Its hard to tell what is supposed to connect to what. I'll have to try to get the frames out some other way. Thanks

Here's a link to the animated schematic which may be useful... http://home.clear.net.nz/pages/dandavies/Tech%20Info.htm#Animated%20Schematic
Yeah, thanks. That helped a bit more. I'll have to give it another go.

the animated pictures are way too large to fit on my screen

You could try watching it from my website here home.clear.net.nz/pages/dandavies/instructional_animation.htm or increasing the resolution of your display may help too.  Thanks.
