/diy/ - Do It Yourself

Found a couple of old matched JFETs ICs and found out I can turn triangle waves in breddy gud sine waves using a diferential pair. It seems my bench supply project will also generate some signals. Nice. Wish me and the other psu anon luck

>years ago brazil had like 10 types of plugs in use
>for some kinky reason we also have multiple legal tensions
>110,220, 3something the list goes on
>sometimes on the same fucking city
>retarded government instead of picking the most popular plug or chosing the best of 10
>takes the swiss plug, changes it just a little bit so swiss shit can`t fit in
>make 2 versions of it, one with hole sligthly smaller,so retarded monkeys do not burn their TVs and stop being mind controlled
>the plug is fucking directional
>their excuse for picking some random plug from fucking helvetia is ``lel ground pin, be s4fe monkeys``
>most brazilian hovels are not grounded because wtf is safety
>still forced to adapt to this shit standard
>there are still cities with 220 on one side of the street and 110 on the other
