@Jan ohhh right, yes, I have some x-rayed stuff
out of interest, do you use lead shielding?
yeah, that's what I'd like to know as well. and a dosimeter?
mm i was wondering about that too
got my my complete face x-rayed a few weeks ago (teeth) and had to wear a full body lead apron
I use a Geiger counter, it's what I have right now, but I'd like to use a proportional meter
heh i've had my teeth x-rayed, i had to bite something that was very uncomfortable, not sure why, but don't think i had an apron
that's just to keep them from moving I think!
ah yeah heh
yeah I had to. to keep steady for imaging
before we start, I will answer any question and that includes technical ones of course
@Fran Piernas just watched your youtube x-ray video. amazing
linky? don't think i've seen that
@Jan thank you so much :D
@anfractuosity here you have
X-ray video is so sweet. seeing the HDD move...
my favorite part, the HDD
hasn't this been done to animals and humas as well in early X-ray days?
ahh, so you're using phosphor screen right? (like krasnow did too?)
@Jan you mean live fluoroscopy?
@anfractuosity of course, digital screens are very, VERY expensive
i'm curious, if it's possible to diy them
if you skip the fibre part
As late as the 1940s, some shoe stores had fluoroscopy machines in them to show customers how well their shoes were fitting.
OK, folks, good turnout already and a good crowd in the chat. Let's kick it off with Fran Piernas talking about X-rays and high-voltage stuff.
Fran, can you start us off with a little about how you got interested in this area?
Yes of course
First I will introduce myself
Hello everyone, my name is Francisco "Fran" Piernas, I'm a 23 years old physics student at University of Granada in Spain. When I was a kid, I was that kind of kid that disassembled his toys to see what they had inside. I loved to disassemble anything. Sometimes my dad gave me a broken printer for me to disassemble it, and I was the happiest kid ever lol
Then I started building small devices, until I saw a tutorial about a TV flyback using the 2n3055 transistor
And I entered the amazing world of HV stuff
If you guys haven't questions I can start talking about some HV projects I've done X)
Cool, so much to be learned from taking stuff apart. I was always warned not to take TVs apart because of dangerous voltages. I ignored them, lol
heh, how dangerous are the inside of old TVs, i'm kind of scared
by the flyback things
or in microwaves
