Ladies and Gentalmen. I present to you the meyers squarewave

[Dynamite]

After building meyers PWM and VRC (volt regulator) i finally hooked it up to the scope.
and boy was i suprised!!!!!

all components are to spec, even finding the now obsolete IC's
sorry i didn't work out the frequency, i will post the scope setting if someone can work it out.

it actually seems to be squarewaved, squarewaves, if you look closely.
this is then imposed over the hish voltage with an optocouple and SCR. before hitting the VIC.

thats neat... wat do ya think all the 4 or 5 diffrent set'ns are there for?
Difrrent water or temperature or just there for expierimentation or wat....
looks like those last photo's added more harmonics and or added even harmonics.... still man , good job !!!

looking forward to see em after the SCR.

the scope is my firends and i'm still getting the hang of it, hafing never used one before.
but there are some major differences switching between the settings,
i mean chages so big i have to re-adjust the scope after turning the switch around. seem to dramatically change the frequency,

the onlying thing holding me up at the moment is trying to get my hands on a variac. i don't have $100's to spend on parts, basically at the moment the cost of the variac is probably greater than my entire budget at this point.
