Default Hello from a relatively new member

Hi All

My name is Mads Barnkob, 35yo and from Denmark.

I have been involved in amateur high voltage and general electronics for about 10 years now. Besides having owned a few handheld lasers as a kid, I have lately acquired laser modules from different old medical equipment or handheld devices.

I originally became a member of this forum when someone asked about Tesla coils in the geeks section, later on posted a little bit about a old Coherent power supply.

I run a few websites like Kaizer Power Electronics | High voltage enthusiasm and https://www.highvoltageforum.net also there is my youtube channel for electronics related content: https://www.youtube.com/channel/UCSu...WiL-sl0UeYeJvQ

Kind regards
Mads

Nice intro Mads, glad to have you around.
+rep for your intro.

For God so loved the world that He gave His only begotten Son, that whoever believes in Him
should not perish but have everlasting life.
For God did not send His Son into the world to condemn the world,

but that the world through Him might be saved.
“He who believes in Him is not condemned;
but he who does not believe is condemned already, because he has not believed in the name of the only begotten Son of God.
And this is the condemnation, that the light has come into the world, and men loved darkness rather than light, because their deeds were evil.
For everyone practicing evil hates the light and does not come to the light, lest his deeds should be exposed.
But he who does the truth comes to the light, that his deeds may be clearly seen, that they have been done in God.”
(John 3:16-21)
─────────────────────────────────☀
If you confess with your mouth, “Jesus is Lord,” and believe in your heart that God raised Him from
the dead, you will be saved.
For it is with your heart that you believe unto righteousness
and it is with your mouth that you confess
your faith and
are saved.
(Romans 10:9-10)

Welcome! Pushing the envelope are we? As if high voltage wasn't already enough, now photon's in mass collimated quantity! Wait, I wrote mass... hmmmm, high collimated quantity is more accurate, no mass there.

Welcome to the forum Mads, let's see we've got high voltage and photons, does that mean we have a functioning light saber on the horizon? Heeee.

Enjoy and be safe and Welcome again.
