I know it's been a year but this is not quite correct L means "LIVE" not "Load"The Live side is connected to the fuse and then is available right under the Nuetral post. There is no post on the "LIVE" side because you want to go through the fuse. I can't tell if there is an internal connection to the switch or not. I'm guessing probably not.be cool if the OP came back and indicated what they found.

Using a linear regulator to provide power 1.5V of power from a 12 volt power supply isn't going to be anywhere close to efficient. You end up with a 10.5 volt volt drop across the regulator being burned off as heat. If your circuit uses 1 amp, then your circuit is using 1.5 Watts of power and your power supply is using 10.5 Watts. 7 times more than your circuit and a total of 12 watts of power. When you are burning that much power you are going to need a big heat sink on your 317. At lower currents, it might not be that big a deal but any time you have it set to 1.5 your power supply is going to be using 7 times as much power as your circuit whether it's 100 mW and 0.7 Watts or 1 Watt and 7 Watts.Might want to consider a variable switching regulator. While they are more expensive, ...

While they are more expensive, in my opinion they are worth the cost.

I've used the muriatic acid and proxide method. Question: How/where do you dispose of it?

You can get square buckets. ;-)

• A couple issues:1- Nobody had to reverse engineer the Arduino. The wonderful people at Arduino released all the hardware files as open source. Making and selling clones is legal as long as you don't use the Arduino trademark or try to pass it off as an official "Arduino". Those that do are guilty of trademark infringement.More information here: https://blog.arduino.cc/2013/07/10/send-in-the-clo...2 - Your claim that "<Samsung>literally wait for a new iPhone to come on, then buy a few, and very quickly make the same thing or better versions in a different case and for the 3rd of the price..." Is outlandish and slanderous. I can't believe such a claim is allowed to be published here without any evidence to back it up. Apple makes phones, Samsung makes phone...

Is outlandish and slanderous. I can't believe such a claim is allowed to be published here without any evidence to back it up. Apple makes phones, Samsung makes phones. In the past, Samsung has stepped on the toes of Apple but Apple has been found guilty of infringing Samsung as well. The world of copyright, patent, and trademark infringement can be a very muddled place. I'd be very careful about making these types of claims. You could find yourself on the wrong end of a defamation lawsuit with a very big, very powerful company.
